This report evaluates how well EECCA countries have done in ensuring people’s access to adequate water supply and sanitation services since their Economic, Finance, and Environment Ministers adopted the Almaty Guiding Principles to support such...
The aim of these studies is to demonstrate the time period for which stability has been shown in representative commodities from crops. Freezer storage stability studies should include sufficient starting material and should have a sufficiently high ...

This Test Guideline describes methods to determine the water solubility of test substances. The water solubility of a substance is the saturation mass concentration of the substance in water at a given temperature. This guideline addresses the ...
French
This Test Guideline is aimed at estimating the adsorption/desorption behaviour of a chemical on different soil types. The goal is to obtain a sorption value which can be used to predict partitioning under a variety of environmental conditions; to ...
French
This Test Guideline describes a method to determine experimentally Pow values in the range log Pow between -2 and 4 (occasionally up to 5). This method can not be used with surface-active materials. The partition coefficient is defined as the ratio ...
