ASTM D1239-22a

Standard Test Method for Resistance of Plastic Films to Extraction by Chemicals

SIGNIFICANCE AND USE
4.1 This test method is intended to be a rapid empirical test to determine the loss of the plasticizer or other extractable components from the plastic film when immersed in liquids commonly used in households.
SCOPE
1.1 This test method for resistance of plastic films to chemicals covers the measurement of the weight loss of film after immersion in chemicals.  
Note 1: There is no known ISO equivalent to this standard.
Note 2: Film is defined as sheeting having nominal thickness not greater than 0.25 mm (0.010 in.), in accordance with Terminology D883.  
1.2 The values stated in SI units are to be regarded as standard. The values stated in other units are nominal values given for information only.  
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
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.
