(Test Method)Standard Test Method for Quantitating Non-UV-Absorbing Nonvolatile Extractables from Microwave Susceptors Utilizing Solvents as Food Simulants (Withdrawn 2024)
Standard Test Method for Quantitating Non-UV-Absorbing Nonvolatile Extractables from Microwave Susceptors Utilizing Solvents as Food Simulants (Withdrawn 2024)
SIGNIFICANCE AND USE
5.1 This test method was developed to measure non-UV-absorbing nonvolatile extractables that may be present and migrate from a microwave susceptor material during use. It may be a useful procedure to assist in minimizing the amount of non-UV-absorbing nonvolatile extractables either through susceptor design or manufacturing processes.
5.2 Supplementation of this procedure with other analytical technologies such as high-pressure liquid chromatography, supercritical fluid chromatography, or infrared or other forms of spectroscopy may provide the analyst with additional information regarding the identification of the components of the non-UV-absorbing nonvolatile extractables in the susceptor.
SCOPE
1.1 This test method is applicable to complete microwave susceptors.
1.2 This test method covers a procedure for quantitating non-UV-absorbing nonvolatile compounds which are extractable when the microwave susceptor is tested under simulated use conditions for a particular food product.
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.4 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.
1.5 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.
WITHDRAWN RATIONALE
This test method covered a procedure for quantitating non-UV-absorbing nonvolatile compounds which are extractable when the microwave susceptor is tested under simulated use conditions for a particular food product.
Formerly under the jurisdiction of Committee F02 on Primary Barrier Packaging, this test method was withdrawn in April 2024. This standard is being withdrawn without replacement due to its limited use by industry.
