ISO 13229:2010规定了用于测定来自管,配件或化合物的未增塑聚氯乙烯(PVC)树脂的粘度数(也称为比浓粘度)和K值的方法。 在ISO 13229:2010中,仅详细说明了PVC树脂的隔离(或分离)方法
ISO 13229:2010 specifies a method for the determination of the viscosity number (also known as reduced viscosity) and K-value of an unplasticized poly(vinyl chloride) (PVC) resin derived from a pipe, fitting or compound. In ISO 13229:2010, only the method for isolation (or separation) of the PVC resin is detailed.
