1、Designation:F111516Standard Test Method forDetermining the Carbon Dioxide Loss of BeverageContainers1This standard is issued under the fixed designation F1115;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.

2、A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 The objective of this test method is to determine thecarbon dioxide(CO2)loss from plastic beverage containersafter a specified period of

3、storage time.1.2 Factors contributing to this pressure loss are volumeexpansion and the gas transport characteristics of the package,including permeation and leakage.1.3 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.4 This st

4、andard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 AST
