The ASTM F1500-98 (2019) standard defines a method for the quantitative measurement of non-volatile extractable compounds that absorb non-UV light from microwave receptors using solvents as food simulants. This method is used to evaluate the release of non-volatile compounds that do not absorb UV light from microwave receptors under conditions of simulated food use, thereby helping to reduce the migration of these compounds. Testing includes an assessment of the integrity of the microwave receptors and additional information can be obtained through Miscellaneous analytical techniques such as high voltage liquid chromatograph or infrared Light spectrum. Users are required to comply with relevant safety and environment codes and operate according to standard guidance.
