This test method provides a guide for evaluating emulsification characteristics of pesticide emulsifiable concentrates. It defines the stability of emulsified particles in water. Although not absolute, the test method is a measure of expected emulsion stability in agricultural application equipment.
1.1 This test method describes a general procedure for the determination of emulsification spontaneity and the emulsion stability characteristics of pesticide emulsifiable concentrates when diluted with water.
1.2 Proper safety and hygiene precautions must be taken when working with pesticide formulations to prevent skin or eye contact, vapor inhalation, and environmental contamination. Read and follow all handling instructions for the specific formulation and conduct the test in accordance with good laboratory practice.
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

This International Standard specifies a high-performance liquid chromatography (HPLC) method for qualitativeand quantitative determination of herbicides of various substance classes in soils. This method coverstriazines including their related metabolites, phenyl urea compounds and other herbicides. Compounds areidentified and quantified with UV-detection.The limit of detection for triazines and phenyl urea compounds is ~ 0,01 mg/kg dry matter. It is dependentupon both the compound and the soil matrix.
