General Information
Frequently Asked Questions
ICS 49.025.60 is a classification code in the International Classification for Standards (ICS) system. It covers "Textiles". The ICS is a hierarchical classification system used to organize international, regional, and national standards, facilitating the search and identification of standards across different fields.
There are 66 standards classified under ICS 49.025.60 (Textiles). These standards are published by international and regional standardization bodies including ISO, IEC, CEN, CENELEC, and ETSI.
The International Classification for Standards (ICS) is a hierarchical classification system maintained by ISO to organize standards and related documents. It uses a three-level structure with field (2 digits), group (3 digits), and sub-group (2 digits) codes. The ICS helps users find standards by subject area and enables statistical analysis of standards development activities.

1.2 The definitions cover, in most cases, special meanings used in the composites industry. No attempt has been made to include common meanings of the same terms as used outside the composites industry.
1.3 Definitions included have, in general, been approved as standard.
1.4 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 For application areas such as optical fiber and cable reinforcements, aramid is usually used in a linear – not twisted – form. For designing constructions like this, it is essential to use data based on a specimen without twist applied.
5.1.1 The modulus and FASE of twisted yarns demonstrate reduced values when compared to p-aramid flat yarns.
5.1.2 Use Test Method D7269 for testing of twisted p-aramid yarns.
5.2 The levels of tensile properties obtained when testing aramid yarns are dependent on the age and history of the specimen and on the specific conditions used during the test. Among these conditions are rate of stretching, type of clamps, gauge length of specimen, temperature and humidity of the atmosphere, rate of airflow across the specimen, and temperature and moisture content of the specimen. Testing conditions accordingly are specified precisely to obtain reproducible test results on a specific sample.
5.3 FASE (Force At Specified Elongation) describes the absolute resistance of the p-aramid flat yarn to an imposed elongation.
5.4 Modulus is a measure of resistance of yarn or cord to extension as a force is applied. It is useful for estimating the response of a textile reinforced structure to the application of varying forces and rates of stretching. Although modulus may be determined at any specified force, initial modulus is the value most commonly used.
5.5 Shape, size, and internal construction of the end-product can have appreciable effect on product performance. It is not possible, therefore, to evaluate the performance of end product in terms of the reinforcing material alone.
5.6 If there are differences of practical significance between reported test results for two laboratories (or more), comparative tests should be performed to determine if there is a statistical bias between them, using competent statistical assistance. As a minimum, test samples should be used that are as homogeneous as possible, that are drawn from ...

This specification covers the requirements for fibrous glass blanket thermal and acoustical insulation for use in aircraft applications up to a specified temperature. The fibrous glass blanket insulation are classified into types according to temperature limits, into classes based on acoustical properties, grades according to nominal density and into groups based on thickness. The insulation can either be water repellent or non-water repellent. The materials should conform to the required values of density, handleability, burning characteristics, water repellency and wicking (for water-repellent insulation only), odor emission, service temperature, apparent thermal conductivity, specific transverse airflow resistance, and breaking strength.

For specific applications, the maximum temperature shall be agreed upon between the supplier and the purchaser.

SIGNIFICANCE AND USE
Fiber density is useful in the evaluation of new materials at the research and development level and is one of the material properties normally given in fiber specifications.
Fiber density is used to determine fiber strength and modulus both of a fiber bundle and an individual filament. These properties are based on load or modulus slope over an effective area. Fiber density may be used with lineal mass of the fiber to give an approximation of effective tow area. Tow area divided by the average number of filaments in a tow gives an approximation of the effective area of an individual filament.
Fiber density is used as a constituent property when determining reinforcement volume and void volume based on reinforcement mass and laminate density.
SCOPE
1.1 This test method covers the determination of the density of high-modulus fibers and is applicable to both continuous and discontinuous fibers.
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 This standard may involve hazardous materials, operations, and equipment. 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.
