Contractors who construct swimming pools

results of accuracy grade 1 (precision grade) or accuracy grade 2 (engineering grade) are obtained

the evaluation of the hazardous situations and the risk levels as well as the classification of priority levels including the filtering process have been moved to Clause 5

Plastics. Polymer dispersions. Determination of free formaldehyde Ingestion-build-111333 5 Material1 Scope This International Standard describes two methods for the determination of free formaldehyde (HCHO) in polymer dispersions. The procedure has been evaluated using acrylic, acrylonitrile butadiene, carboxylated styrenebutadiene and vinyl acetate polymer dispersions. Both test methods may also be applicable to polymer dispersions of other compositions. Method A is the preferred method for polymer dispersions with a free formaldehyde content
