Standard Test Method for Qualitative Analysis of Volatile Extractables in Microwave Susceptors Used to Heat Food Products

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 extractable identification with a variety of volatile extractables at a level of 0.010 [mu]g/in. of susceptor. For extractables not evaluated, the analyst should perform studies to determine when extractable 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 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.
