Thermoplastic pipes. Resistance to liquid chemicals. Classification - Unplasticized poly(vinyl chloride) (PVC-U), high-impact poly(vinyl chloride) (PVC-HI) and chlorinated poly(vinyl chloride) (PVC-C) pipes1 Scope The method of classification given in this part of ISO 4433 serves to determine the chemical resistance of unplasticized poly(vinyl chloride) (PVC U), high impact poly(vinyl chloride) (PVC HI) and chlorinated poly(vinyl chloride) (PVC C) pipes designed for the conveyance of liquids in the absence of pressure and stress (e. g. due to earth loads or traffic loads, dynamic or internal stresses). To determine the chemical resistance, the method

— weather tightness of the roof

First aid kits can be complemented by other items that have been identified during a risk assessment if necessary

Calculation periods

Textiles — Tests for colour fastness — Part B02: Colour fastness to artificial light: Xenon arc fading lamp test
