    Abstract

    This test method covers the standard procedures for measuring and profiling surface temperatures attained by microwave interactive packaging and cooking aids (that is, susceptors). This procedure is useful for measuring susceptor/food interface temperatures during microwave preparation of foods with susceptor-based packaging, heating pads, and crisping sleeves, etc. It may also be used in the temperature profiling of susceptors exposed in vials used for volatile extractives testing, or in liquid (PTFE-fluorocarbon polymer) extraction cells used for nonvolatile extractives testing. The latter procedures are performed to establish test conditions for conducting extraction and migration studies using temperature versus time profiles approximating those for actual microwave preparation of the product.

    Significance and Use

    1. Scope

    1.1 This is a test method for measuring surface temperatures attained by microwave interactive packaging and cooking aids (that is, susceptors). It is useful for measuring susceptor/food interface temperatures during microwave preparation of foods with susceptor-based packaging, heating pads, and crisping sleeves, etc. It may also be used to measure the temperature of a susceptor exposed to extractives testing or in a liquid extraction cell to be used for nonvolatile extractives testing. The latter procedures are performed to establish test conditions for conducting extraction and migration studies using temperature versus time profiles approximating those for actual microwave preparation of the product.

    1.1.1 Several of the steps of this test method are taken directly from Test Method F1308 which gives extraction testing procedures for susceptors.

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

    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 and health practices and determine the applicability of regulatory limitations prior to use.
