2、 adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of lastreapproval. A superscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This practice covers guidance and direction to suppliers, purchaser
3、s, and users in the handling, transportation, and storageof HFC236fa.1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in eachsystem may not be exact equivalents; therefore, each system shall be used independently of the other.
4、Combining values from thetwo systems may result in non-conformance with the given in parentheses are mathematical conversions to SI units that areprovided 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
5、 with its use. It is the responsibilityof the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatorylimitations prior to use.2.
