Scope

GB/T 21855-2008 is the English-translated version of 化学品与pH有关的水解作用试验.

GB/T 21855-2008 — This standard specifies the scope of the information related to the chemical and pH hydrolysis tests, definitions of terms, the principle of the test, the test substance, reference Interpretation and evaluation of substance, quality control, test methods, data and reporting the results.

This standard applies to the determination of the hydrolysis of the ability of chemicals and pH-related. This standard applies to those with sufficient accuracy and flexibility have Compound analytical method sensitivity (not markers and markers).

It applies for minor volatile and nonvolatile has sufficient water solubility Compound. It does not apply to high volatility (e.g. fumigants, organic solvent), in aqueous solution under experimental conditions in the preserved compound. Test substance for minimal water-soluble difficult [8].

What this standard covers

This standard specifies the chemical hydrolysis of pH test range, definitions of terms, test principle, the test substance information, reference material, quality control, testing methods, data and reporting, interpretation of results and evaluation. This standard applies to the determination of pH on chemical hydrolysis capabilities. This standard applies to those with sufficient accuracy and sensitivity of the analytical method compounds. For minor volatile and non -volatile compound having a sufficiently high water solubility. Not applicable to highly volatile, under the experimental conditions to be stored in an aqueous solution of the compound. On very small water-soluble substances are difficult to test.
