(Practice)Standard Practice for Handling, Transportation, and Storage of HFC Blend B (CH2FCF3, CHF2 CF3, and CO2)
Standard Practice for Handling, Transportation, and Storage of HFC Blend B (CH<sub>2</sub>FCF<sub>3</sub>, CHF<sub>2</sub> CF<sub>3</sub>, and CO<sub>2</sub>)
SIGNIFICANCE AND USE
4.1 This practice provides requirements for the handling, transportation, and storage of HFC Blend B encountered in distribution through both commercial and military channels. It is intended to ensure that HFC Blend B is handled, transported, and stored in such a way that its physical property virtues are not degraded. Transport may be by various means, such as, but not limited to, highway, rail, water, and air.
SCOPE
1.1 This practice covers guidance and direction to suppliers, reclaimers, purchasers, and users in the handling, transportation, and storage of HFC Blend B.
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.3 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.
