This Test Guideline describes methods to measure the viscosity of liquids. The methods listed are appropriate in principle for the investigation of Newtonian liquids. The measurement of non-Newtonian liquids is only possible with the rotational viscometer. Viscosity measurements are carried out...

The test substance is administered in graduated doses to several groups of males and females. Males should be dosed for a minimum of four weeks; females should be dosed throughout the study (approximately 54 days). Normally, matings “one male to one female” should be used in this study. This...

The Globally Harmonised System for the Classification and Labelling of Chemicals defines skin corrosion as the production of irreversible tissue damage in the skin following the application of a test material. The test material (150 µL for liquids or solid with 150 µL of deionised water added...

Studies of Metabolism in Crops are used to elucidate the degradation pathway of the active ingredient and require the identification of the metabolism and/or degradation products when a pesticide is applied to a crop directly or indirectly. A Metabolism in Crops study should be submitted for...

This Test Guideline describes a method which is an adaptation of the Soap and Detergent Association semi-continuous activated sludge (SCAS) procedure for assessing the primary biodegradation of alkyl benzene sulphonate. The test does not simulate those conditions experienced in a sewage...

This study relates to the analysis, via dermal application, of the health hazard of solid or liquid test substance. This method is composed of two tests: the main test and the limit test. This Test Guideline is intended for use with the adult rat, rabbit or guinea pig. At least 10 animals (5...

Metabolism in Livestock studies are used to determine the qualitative and quantitative metabolism and/or degradation of the active ingredient resulting from pesticide use in feedstuffs, direct application to livestock, or premise treatment. The studies provide an estimate of total residues in...

The purpose of the in vitro chromosome aberration test is to identify agents that cause structural chromosome aberrations in cultured mammalian somatic cells. Structural aberrations may be of two types: chromosome or chromatid. The in vitro chromosome aberration test may employ cultures of...
