Sistemet e tubacioneve termoplastikë për aplikimin e tyre jo nën trysni - Tubat dhe pajisjet prej poliklorurvinili të pa plastifikuar - Përcaktimi i numrit të viskozitetit dhe të vlerës K (ISO 13229:2010)
Thermoplastics piping systems for non-pressure applications - Unplasticized poly(vinyl chloride) (PVC-U) pipes and fittings - Determination of the viscosity number and K-value (ISO 13229:2010)
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.
