Thermoplastics piping systems for non-pressure applications. Unplasticized poly(vinyl chloride) (PVC-U) pipes and fittings. Determination of the viscosity number and K-value1 Scope This International Standard 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 this International Standard, only the method for isolation (or separation) of the PVC resin is detailed, while the determination of the viscosity number is given in ISO 16282. The presence of other additives or
