GB/T 21757-2008
ActiveChemicals - Test method of acute oral toxicity for chemicals - Acute toxic class method
化学品 急性经口毒性试验 急性毒性分类法
Application Summary AI generated
This standard specifies a stepwise procedure for assessing the acute oral toxicity of chemicals by classifying them into hazard categories based on fixed-dose observations. It is applied in the pharmaceutical, chemical, and pesticide industries for safety evaluation of substances, particularly during product development and regulatory compliance testing. The method is used to determine the toxic class of a chemical without requiring a precise LD50 value, reducing animal use while ensuring reliable hazard classification.
