This International Standard specifies a guide for the selective quantitative analysis by immunoassays of environmental chemicals such as pesticides (including insecticides) or their metabolites in drinking, ground and surface water. The application range of the procedure for the analysis of pesticides in drinking water applies to mass concentrations W 0,05 _g/l. Therefore, the determination limit…

This International Standard specifies a method for the determination of phenoxyalkanoic acids in ground and drinking water in mass concentrations W 50 ng/l (detailed information is given in Table A.1 of annex A). Examples of phenoxyalkanoic acids which can be determined by this method are given in Table 1. This method may be applicable to compounds not mentioned in Table 1 or to other types of…

This International Standard specifies a method for testing the flexural fatigue resistance of piping assemblies under pressure. The method is applicable to polyethylene (PE) tapping tees, PE/metal transition fittings and PE branch saddles, intended for use with PE pipes having a nominal outside diameter de u 63 mm. NOTE The test is based on simulating the stresses generated in practice on buried…
