2、r oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This test method is applicable to complete microwavesusceptors
3、.1.2 This test method covers a procedure for quantitatingnon-UV-absorbing nonvolatile compounds which are extract-able when the microwave susceptor is tested under simulateduse conditions for a particular food product.1.3 The values stated in SI units are to be regarded asstandard.No other units of
4、measurement are included in thisstandard.1.4 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety,health,and environmental practices and deter-mine the applicability of

10、rities.The solvent washes are com-bined and the solvents evaporated just to dryness.The residueis redissolved in a measured quantity of chloroform and thesample split for gravimetric or other analyses,such as HPLC orIR.For the gravimetric determination,a measured portion ofthe sample is filtered and
11、 evaporated and the residue weighed.For other analyses,the remainder of the sample is evaporatedand may be reconstituted in dimethylacetamide prior to injec-tion(see Test Method F1349 for quantitation of UV-absorbingnonvolatiles by HPLC),or treated appropriately prior toexamination by other chromato
