This part of ISO 1628 specifies a method for the determination of the viscosity number (also referred to as "reduced viscosity") of dilute solutions of thermoplastic polyesters (TPs) in certain specified solvents. The method is applicable to poly(ethylene terephthalate) (PET), poly(butylene terephthalate) (PBT), poly- (cyclohexylenedimethylene terephthalate) (PCT), and poly(ethylene naphthalate) (PEN), as well as to copolyesters and other polyesters, referred to in iso:proj:76396ISO 20028-1:2019, that are soluble in one of the specified solvents under the specified conditions. The viscosity number is determined by the general procedure specified in iso:proj:86451ISO 1628-1:2024, observing the particular conditions specified in this part of ISO 1628. The determination of the viscosity number of a thermoplastic polyester provides a measure of the relative molecular mass of the polymer.

 

1.1 This document specifies conditions for the determination of the reduced viscosity (also known as viscosity number) and K-value of PVC resins. It is applicable to resins in powder form which consist of homopolymers of the monomer vinyl chloride and copolymers, terpolymers, etc., of vinyl chloride with one or more other monomers, but where vinyl chloride is the main constituent. The resins can contain small amounts of unpolymerized substances (e.g. emulsifying or suspending agents, catalyst residues, etc.) and other substances added during the course of the polymerization. This document is not applicable, however, to resins having a volatile-matter content in excess of 0,5 % ± 0,1 %, when determined in accordance with iso:proj:39135ISO 1269:2006. In addition to this, it is not applicable to resins which are not entirely soluble in cyclohexanone. 1.2 The reduced viscosity and K-value of a particular resin are related to its molecular mass, but the relationship varies depending on the concentration and type(s) of other monomer(s) present. Hence, homopolymers and copolymers having the same reduced viscosity or K-value can have different molecular masses. 1.3 The values determined for reduced viscosity and K-value, for a particular sample of PVC resin, are influenced differently by the concentration of the solution chosen for the determination. Hence the use of the procedures specified in this document only gives values for reduced viscosity and K-value that are comparable when the concentrations of the solutions used are identical. 1.4 The experimental procedures specified in this document can also be used to characterize the polymeric fraction obtained during the chemical analysis of a PVC composition. However, the values calculated for the reduced viscosity and K-value in these circumstances can deviate form the correct values for the resin used to produce the composition because of the impure nature of the recovered polymer fraction.

 

 

This document provides guidance on the intent of the requirements in iso:proj:88464ISO/DIS 9001 ISO 9001:2026, with examples of possible steps an organization can take to meet the requirements. It does not add to, subtract from, or in any way modify those requirements. This document does not prescribe mandatory approaches to implementation or provide any preferred method of interpretation.

This document specifies a method for identifying microplastics, using microscopic observation, whether the size of captured fibre fragments released from fabrics under washing test conditions. It also specifies a thermal method and a gravimetric method for the quantitative determination of microplastics made of certain synthetic fibres: polyester (PES), polyamide (PA), acrylic (PAN), elastane (EL), polypropylene (PP), and polyethylene (PE). The thermal methods such as pyrolysis-gas chromatography-mass spectrometry (Py-GC-MS) and thermo extraction desorption-gas chromatography - mass spectrometry (TED-GC-MS) are applicable to PES, PAN, PA, and EL. The gravimetric method is applicable to PP and PE, including blended fabrics, provided that non-PP/PE components are dissolved by appropriate solvents so that PP and PE are isolated for quantification. These thermal and gravimetric methods are applicable to fabrics composed of these six synthetic fibres, either alone or in blends with other fibres (e.g., natural or non-target synthetic fibres). Gravimetric method does not apply to: solvent-insoluble components (e.g., aramids) composed with polypropylene and/or polyethylene

 

ISO 1628-3:2010 defines particular conditions for determining the reduced viscosity (also known as viscosity number) and intrinsic viscosity of polyethylenes and polypropylenes at 135 °C in dilute solution. The viscosity of polymer solutions may be affected by additives present in the sample. The value of a reduced viscosity determined by this method may therefore be unreliable if the sample contains fillers or other additives.

Hence, homopolymers and copolymers having the same reduced viscosity or K-value might not have the same molecular mass. 1.3 The values determined for reduced viscosity and K-value, for a particular sample of PVC resin, are influenced differently by the concentration of the solution chosen for the determination. Hence the use of the procedures described in this document only gives values for reduced viscosity and K-value that are comparable when the concentrations of the solutions used are identical. 1.4 Limiting viscosity number is not used for PVC resins. 1.5 The experimental procedures described in this document can also be used to characterize the polymeric fraction obtained during the chemical analysis of a PVC composition. However, the values calculated for the reduced viscosity and K-value in these circumstances might not indicate the actual values for the resin used to produce the composition because of the impure nature of the recovered polymer fraction.
