The principle of the method is maintaining a test portion of the PVC at an agreed temperature in a nitrogen gas stream, absorbing the hydrogen chloride evolved in a given amount of demineralized water, and potentiometrically determining the amount of hydrogen chloride evolved in relation to the recorded change in conductivity of the water. The method is recommended for compounded PVC materials and products only, although it can be used for polymers in powder form under appropriate conditions.

This document specifies the methods of preparation of test specimens and the test methods to be used in determining the properties of polyamide moulding and extrusion materials. It gives the requirements for handling test material and for conditioning both the test material before moulding and the specimens before testing.
This document specifies procedures and conditions for the preparation of test specimens and procedures for measuring properties of the materials from which these specimens are made are given. It lists the properties and test methods that are suitable and necessary to characterize polyamide moulding and extrusion materials.
The properties have been selected from the general test methods in ISO 10350‑1. Other test methods in wide use for, or of particular significance to, these moulding and extrusion materials are also included in this document, as are the designatory properties viscosity number and tensile modulus given in ISO 16396‑1.

This document specifies two procedures for the determination of the melt mass-flow rate (MFR) and
the melt volume-flow rate (MVR) of thermoplastic materials under specified conditions of temperature
and load. Procedure A is a mass-measurement method. Procedure B is a displacement-measurement
method. Normally, the test conditions for measurement of melt flow rate are specified in the material
standard with a reference to this document. The test conditions normally used for thermoplastics are
listed in Annex A.
The MVR is particularly useful when comparing materials of different filler content and when
comparing filled with unfilled thermoplastics. The MFR can be determined from MVR measurements,
or vice versa, provided the melt density at the test temperature is known.
This document is also possibly applicable to thermoplastics for which the rheological behaviour is
affected during the measurement by phenomena such as hydrolysis (chain scission), condensation and
cross-linking, but only if the effect is limited in extent and only if the repeatability and reproducibility
are within an acceptable range. For materials which show significantly affected rheological behaviour
during testing, this document is not appropriate. In such cases, ISO 1133-2 applies.
NOTE The rates of shear in these methods are much smaller than those used under normal conditions of
processing, and therefore it is possible that data obtained by these methods for various thermoplastics will not
always correlate with their behaviour during processing. Both methods are used primarily in quality control.

ISO 6401:2008 specifies a method for the determination of vinyl chloride monomer in homopolymer and copolymer resins of vinyl chloride and compounded materials. The method is based on sample dissolution and headspace gas chromatography. Concentrations of vinyl chloride in the range 0,1 mg/kg to 3,0 mg/kg can be determined.
A "dry method", suitable for PVC resins but not compounded materials, is widely used within the industry for in-house determinations. A separate International Standard based on this methodology is under development.

This document specifies a classification and designation system for a selection of the most common unfilled thermoplastic polymers for plain bearings.
The unfilled thermoplastic polymers are classified on the basis of appropriate levels of distinctive properties, additives and information about their application for plain bearings. The designation system does not include all properties; thermoplastic polymers having the same designation cannot therefore be interchanged in all cases.
It also provides an outline of the properties and applications of the most common unfilled thermoplastic polymers as well as listing some of the fundamental parameters that influence the selection of thermoplastic polymers for use for plain bearings.
NOTE     In the further course of the work, it is intended to prepare standards on “thermosetting polymers” and “mixed polymers” for plain bearings.

This document specifies two categories of method for the determination of the vinyl acetate (VAC) content of ethylene/vinyl acetate (EVAC) copolymer, for use in the designation of such copolymers according to ISO 21301-1. One category is referred to as “reference methods”, the other as “test methods”. The “reference methods” are used to calibrate the method used for the determination of the vinyl acetate content of ethylene/vinyl acetate copolymers. The “test methods” are other methods which can be used for the determination if they are calibrated using one of the reference methods described in Clause 4, provided they show a certain permissible repeatability.

This document specifies a classification and designation system for a selection of the most common unfilled thermoplastic polymers for plain bearings. The unfilled thermoplastic polymers are classified on the basis of appropriate levels of distinctive properties, additives and information about their application for plain bearings. The designation system does not include all properties; thermoplastic polymers having the same designation cannot therefore be interchanged in all cases. It also provides an outline of the properties and applications of the most common unfilled thermoplastic polymers as well as listing some of the fundamental parameters that influence the selection of thermoplastic polymers for use for plain bearings. NOTE In the further course of the work, it is intended to prepare standards on “thermosetting polymers” and “mixed polymers” for plain bearings.
