D02.J0.01 - Jet Fuel Specifications

ABSTRACT
This specification covers purchases of aviation turbine fuel under contract and is intended primarily for use by purchasing agencies. This specification does not include all fuels satisfactory for reciprocating aviation turbine engines, but rather, defines the following specific types of aviation fuel for civil use: Jet A; and Jet A-1. The fuels shall be sampled and tested appropriately to examine their conformance to detailed requirements as to composition, volatility, fluidity, combustion, corrosion, thermal stability, contaminants, and additives.
SCOPE
1.1 This specification covers the use of purchasing agencies in formulating specifications for purchases of aviation turbine fuel under contract.  
1.2 This specification defines the minimum property requirements for Jet A and Jet A-1 aviation turbine fuel and lists acceptable additives for use in civil and military operated engines and aircraft. Specification D1655 was developed initially for civil applications, but has also been adopted for military aircraft. Guidance information regarding the use of Jet A and Jet A-1 in specialized applications is available in the appendix.  
1.3 This specification can be used as a standard in describing the quality of aviation turbine fuel from production to the aircraft. However, this specification does not define the quality assurance testing and procedures necessary to ensure that fuel in the distribution system continues to comply with this specification after batch certification. Such procedures are defined elsewhere, for example in ICAO 9977, EI/JIG Standard 1530, JIG 1, JIG 2, API 1543, API 1595, and ATA-103.  
1.4 This specification does not include all fuels satisfactory for aviation turbine engines. Certain equipment or conditions of use may permit a wider, or require a narrower, range of characteristics than is shown by this specification.  
1.5 Aviation turbine fuels defined by this specification may be used in other than turbine engines that are specifically designed and certified for this fuel.  
1.6 This specification no longer includes wide-cut aviation turbine fuel (Jet B). FAA has issued a Special Airworthiness Information Bulletin which now approves the use of Specification D6615 to replace Specification D1655 as the specification for Jet B and refers users to this standard for reference.  
1.7 The values stated in SI units are to be regarded as standard. However, other units of measurement are included in this standard.  
1.8 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.9 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
5.1 This test method is intended for use in the laboratory or field in evaluating aviation turbine fuel cleanliness.  
5.2 A change in filtration performance after storage, pretreatment, or commingling can be indicative of changes in fuel condition.  
5.3 Relative filterability of fuels may vary, depending on filter porosity and structure, and may not always correlate with results from this test method.  
5.4 Causes of poor filterability in industrial/refinery filters include fuel degradation products, contaminants picked up during storage or transfer, incompatibility of commingled fuels, or interaction of the fuel with the filter media. Any of these could correlate with orifice or filter system plugging, or both.
SCOPE
1.1 This test method covers a procedure for determining the filterability of aviation turbine fuels (for other middle distillate fuels, see Test Method D6426).
Note 1: ASTM specification fuels falling within the scope of this test method are Specifications D1655 and D6615 and the military fuels covered in the military specifications listed in 2.2.  
1.2 This test method is not applicable to fuels that contain undissolved water.  
1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
5.1 DRA is frequently added into multiproduct pipelines to increase throughput or reduce energy requirements of fuel movement. Although these additives are not used in jet fuel, contamination can occur from other products if proper batching guidelines are not followed or by other cases of human error. CRC Report No. 642 reviewed the impact of DRA on jet fuel fit-for-purpose performance and concluded that the fuel spray angle and atomization capability of several engine-type fuel nozzles can be adversely affected impacting high altitude relight performance at elevated concentrations. A method that accurately quantifies the amount of DRA in jet fuel can be useful in confirming the absence of significant contamination to protect the safety of aviation operations. This test method is designed to measure down to sub-100 µg/L levels of DRA in aviation fuel.
SCOPE
1.1 This test method covers the measurement of high molecular weight polymers, in particular pipeline drag reducer additive (DRA), in aviation turbine fuels with a 72 µg/L lower detection limit. The method cannot differentiate between different polymers types. Thus, any non-DRA high molecular weight polymer will cause a positive measurement bias. Further investigation is required to confirm the polymer detected is DRA.  
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.3 Warning—Mercury has been designated by many regulatory agencies as a hazardous substance that can cause serious medical issues. Mercury, or its vapor, has been demonstrated to be hazardous to health and corrosive to materials. Use Caution when handling mercury and mercury-containing products. See the applicable product Safety Data Sheet (SDS) for additional information. The potential exists that selling mercury or mercury-containing products, or both, is prohibited by local or national law. Users must determine legality of sales in their location.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

This specification does not include all fuels satisfactory for reciprocating aviation turbine engines, but rather, defines the following specific types of aviation fuel for civil use: Jet A; and Jet A-1. The fuels shall be sampled and tested appropriately to examine their conformance to detailed requirements as to composition, volatility, fluidity, combustion, corrosion, thermal stability, contaminants, and additives.
SCOPE
1.1 This specification covers the use of purchasing agencies in formulating specifications for purchases of aviation turbine fuel under contract.  
1.2 This specification defines the minimum property requirements for Jet A and Jet A-1 aviation turbine fuel and lists acceptable additives for use in civil and military operated engines and aircraft. Specification D1655 was developed initially for civil applications, but has also been adopted for military aircraft. Guidance information regarding the use of Jet A and Jet A-1 in specialized applications is available in the appendix.  
1.3 This specification can be used as a standard in describing the quality of aviation turbine fuel from production to the aircraft. However, this specification does not define the quality assurance testing and procedures necessary to ensure that fuel in the distribution system continues to comply with this specification after batch certification. Such procedures are defined elsewhere, for example in ICAO 9977, EI/JIG Standard 1530, JIG 1, JIG 2, API 1543, API 1595, and ATA-103.  
1.4 This specification does not include all fuels satisfactory for aviation turbine engines. Certain equipment or conditions of use may permit a wider, or require a narrower, range of characteristics than is shown by this specification.  
1.5 Aviation turbine fuels defined by this specification may be used in other than turbine engines that are specifically designed and certified for this fuel.  
1.6 This specification no longer includes wide-cut aviation turbine fuel (Jet B). FAA has issued a Special Airworthiness Information Bulletin which now approves the use of Specification D6615 to replace Specification D1655 as the specification for Jet B and refers users to this standard for reference.  
1.7 The values stated in SI units are to be regarded as standard. However, other units of measurement are included in this standard.  
1.8 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.9 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
5.1 This test method is intended for use in the laboratory or field in evaluating aviation turbine fuel cleanliness.  
5.2 A change in filtration performance after storage, pretreatment, or commingling can be indicative of changes in fuel condition.  
5.3 Relative filterability of fuels may vary, depending on filter porosity and structure, and may not always correlate with results from this test method.  
5.4 Causes of poor filterability in industrial/refinery filters include fuel degradation products, contaminants picked up during storage or transfer, incompatibility of commingled fuels, or interaction of the fuel with the filter media. Any of these could correlate with orifice or filter system plugging, or both.
SCOPE
1.1 This test method covers a procedure for determining the filterability of aviation turbine fuels (for other middle distillate fuels, see Test Method D6426).
Note 1: ASTM specification fuels falling within the scope of this test method are Specifications D1655 and D6615 and the military fuels covered in the military specifications listed in 2.2.  
1.2 This test method is not applicable to fuels that contain undissolved water.  
1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
5.1 DRA is frequently added into multiproduct pipelines to increase throughput or reduce energy requirements of fuel movement. Although these additives are not used in jet fuel, contamination can occur from other products if proper batching guidelines are not followed or by other cases of human error. CRC Report No. 642 reviewed the impact of DRA on jet fuel fit-for-purpose performance and concluded that the fuel spray angle and atomization capability of several engine-type fuel nozzles can be adversely affected impacting high altitude relight performance at elevated concentrations. A method that accurately quantifies the amount of DRA in jet fuel can be useful in confirming the absence of significant contamination to protect the safety of aviation operations. This test method is designed to measure down to sub-100 µg/L levels of DRA in aviation fuel.
SCOPE
1.1 This test method covers the measurement of high molecular weight polymers, in particular pipeline drag reducer additive (DRA), in aviation turbine fuels with a 72 µg/L lower detection limit. The method cannot differentiate between different polymers types. Thus, any non-DRA high molecular weight polymer will cause a positive measurement bias. Further investigation is required to confirm the polymer detected is DRA.  
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.3 Warning—Mercury has been designated by many regulatory agencies as a hazardous substance that can cause serious medical issues. Mercury, or its vapor, has been demonstrated to be hazardous to health and corrosive to materials. Use Caution when handling mercury and mercury-containing products. See the applicable product Safety Data Sheet (SDS) for additional information. The potential exists that selling mercury or mercury-containing products, or both, is prohibited by local or national law. Users must determine legality of sales in their location.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

1.2 This specification defines specific types of aviation turbine fuel for civil use in the operation and certification of aircraft and describes fuels found satisfactory for the operation of aircraft and engines. The specification can be used as a standard in describing the quality of aviation turbine fuels from the refinery to the aircraft.  
1.3 This specification does not define the quality assurance testing and procedures necessary to ensure that fuel in the distribution system continues to comply with this specification after batch certification. Such procedures are defined elsewhere, for example in ICAO 9977, EI/JIG Standard 1530, JIG 1, JIG 2, API 1543, API 1595, and ATA-103.  
1.4 This specification does not include all fuels satisfactory for aviation turbine engines. Certain equipment or conditions of use may permit a wider, or require a narrower, range of characteristics than is shown by this specification.  
1.5 Aviation turbine fuels defined by this specification may be used in other than turbine engines that are specifically designed and certified for this fuel.  
1.6 This specification no longer includes wide-cut aviation turbine fuel (Jet B). FAA has issued a Special Airworthiness Information Bulletin which now approves the use of Specification D6615 to replace Specification D1655 as the specification for Jet B and refers users to this standard for reference.  
1.7 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

ABSTRACT
This specification covers the use of purchasing agencies in formulating specifications for purchases of aviation turbine fuel under contract. This specification defines type Jet B wide-cut aviation turbine fuel intended for use in aircraft that are certified to use such fuel. This fuel has advantages for operations in very low temperature environments compared with other fuels. The aviation turbine fuel shall consist of blends of refined hydrocarbons derived from crude petroleum, natural gasoline, or blends thereof with synthetic hydrocarbons. Additives such as antioxidants, metal deactivator, electrical conductivity additive, leak detection additive, and other additives including biocidal additive and fuel system icing inhibitor, may be added to the aviation turbine fuel in the amount and of the composition specified. The aviation turbine fuel shall conform to the requirements prescribed for the following: aromatics, mercaptan sulfur content, sulfur content, distillation temperature, distillation residue, distillation loss, density, vapor pressure, freezing point, net heat of combustion, smoke point and naphthalene content, copper strip corrosion, thermal stability such as filter pressure drop and tube deposits, existent gum, electrical conductivity, and microseparometer rating. The test methods for determining conformance to these specified requirements are given.
SCOPE
1.1 This specification covers the use of purchasing agencies in formulating specifications for purchases of aviation turbine fuel under contract.  
1.2 This specification defines one specific type of aviation turbine fuel for civil use. This fuel has advantages for operations in very low temperature environments compared with other fuels described in Specification D1655. This fuel is intended for use in aircraft that are certified to use such fuel.
Note 1: The technical requirements of this product, at the time of the first publication of this specification, are substantially identical to the requirements of Jet B in Specification D1655.  
1.3 This specification does not define the quality assurance testing and procedures necessary to ensure that fuel in the distribution system continues to comply with this specification after batch certification. Such procedures are defined elsewhere, for example in ICAO 9977, EI/JIG Standard 1530, JIG 1, JIG 2, API 1543, API 1595, and ATA-103.

ABSTRACT
This specification covers purchases of aviation turbine fuel under contract and is intended primarily for use by purchasing agencies. This specification does not include all fuels satisfactory for reciprocating aviation turbine engines, but rather, defines the following specific types of aviation fuel for civil use: Jet A; and Jet A-1. The fuels shall be sampled and tested appropriately to examine their conformance to detailed requirements as to composition, volatility, fluidity, combustion, corrosion, thermal stability, contaminants, and additives.

SIGNIFICANCE AND USE
5.1 This test method is intended for use in the laboratory or field in evaluating aviation turbine fuel cleanliness.  
5.2 A change in filtration performance after storage, pretreatment, or commingling can be indicative of changes in fuel condition.  
5.3 Relative filterability of fuels may vary, depending on filter porosity and structure, and may not always correlate with results from this test method.  
5.4 Causes of poor filterability in industrial/refinery filters include fuel degradation products, contaminants picked up during storage or transfer, incompatibility of commingled fuels, or interaction of the fuel with the filter media. Any of these could correlate with orifice or filter system plugging, or both.
SCOPE
1.1 This test method covers a procedure for determining the filterability of aviation turbine fuels.Note 1—ASTM specification fuels falling within the scope of this test method are Specifications D1655 and D6615 and the military fuels covered in the military specifications listed in 2.2.  
1.2 This test method is not applicable to fuels that contain undissolved water.  
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
