This Test Guideline describes methods to determine the surface tension (in N/m) of aqueous solutions. The methods are based on the measurement of the force whic

This Test Guideline describes methods to determine the water solubility of test substances. The water solubility of a substance is the saturation mass concentra

This Test Guideline describes a laboratory test method to assess abiotic hydrolytic transformations of chemicals in aquatic systems at pH values normally found

This Test Guideline describes a method to analyse the solution/extraction behaviour of polymers in water, which uses the flask method with modifications. Three

This Test Guideline describes the procedure for the electronic determination of pH of an undiluted aqueous solution or dispersion, the pH of a dilution of a sol
