- Various forms of test data can be searched, exported and printed out
Test Principle
Total Migration
The specimen shall be soaked in the solution which is simulator of various food. When the solution is evaporated to dryness, the total migration of non-volatile contents can be measured and calculated.
Non-volatile-matter Content
The specimen shall be soaked in standard reagent. When the reagent and blank liquid bath are evaporated to dryness, the total weight of non-volatile-matter contents can be obtained by comparing with the blank liquid.
Test Standards
ISO 759-1981, GB 31604.8-2016, GB/T 9740-2008, YBB00342002-2015 and YBB00132002-2015, etc.
