OECD 122 OECD Guidelines for the Testing of Chemicals, Standard Test Method for Determination of pH, Acidity and Alkalinity

EUROLAB laboratory provides testing and compliance service within the scope of OECD 122 standard. The OECD Guidelines for testing chemicals are a collection of approximately 150 of the most relevant internationally recognized test methods used by government, industry and independent laboratories to identify and characterize the potential hazards of chemicals.

They are a set of tools for professionals used primarily in regulatory safety testing and then in chemical and chemical product declaration, chemical registration and chemical evaluation.

They can also be used for selection and sequencing of candidate chemicals during the development of new chemicals and products and in toxicology research. This test group covers physical-chemical properties.

This test guide describes the procedure for electronically determining the pH of an undiluted aqueous solution or dispersion, the pH of diluting a solution or dispersion in water, or the pH of a chemical diluted to its end-use concentration.

It also describes procedures for determining the acid reserve or alkaline reserve for a chemical that is strong or weak acid or alkali and acidic or alkaline.

The pH of an aqueous solution or dispersion in water is determined with a pH meter equipped with a suitable electrode system. The acidity or alkalinity of a solution or dispersion in water is determined by titration with standard acid or alkali using electrometric endpoint detection.
