ASTM F1519-98R19

1.1 This test method is applicable to complete microwave susceptors.

1.2 This test method covers a procedure for identifying volatile extractables which are released when a microwave susceptor sample is tested under simulated end use conditions. The extractables are identified using gas chromatography/mass spectrometry (GC/MS).

1.3 This test method was evaluated for the identification of a variety of volatile extractables at a level of 0.010 μg/in.² of susceptor surface. For extractables not evaluated, the analyst should perform studies to determine the level of extractable at which identification is achievable.

1.4 The analyst is encouraged to run known volatile extractables and/or incorporate techniques such as gas chromatography/high resolution mass spectrometry (GC/HRMS), gas chromatography/infrared spectroscopy (GC/IR) or other techniques to aid in verifying the identity of or identifying unknown volatile extractables. The analyst is referred to Practice E260 for additional guidance.

1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.6 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.

1.7 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.
