ISO 11337:2010 specifies a method for determining epsilon‑caprolactam and omega‑laurolactam in polyamides by gas chromatography. It is suitable particularly for the determination of epsilon‑caprolactam in polyamide 6 and omega‑laurolactam in polyamide 12. Bearing in mind that gas chromatography offers a wide range of possible conditions, the method specified is that shown to have been suitable in practice.
Two variants of the basic method are specified:
Method A is an extraction method with boiling methanol, and the extract is injected into a gas chromatograph.
Method B is a method using a solvent, and the solution is injected into a gas chromatograph.

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 quality levels for imperfections in joints in thermoplastic moulded components due to the joining process. This document does not describe imperfections that can be generated either during service or present before joining, such as poor fit up. The correct preparation before joining is described in the relevant thermal joining process specification (TJPS), as defined in ISO 23512. Three quality levels are specified in order to permit application for a wide range of the following joining processes: a) ultrasonic welding; b) ultrasonic spot welding; c) infrared welding; d) hot gas convection welding; e) vibration welding; f) spin welding; g) laser welding; h) hot plate welding; and i) heat staking: hot air; electrical, infrared and ultrasonic. They are designated by symbols B, C and D, where B is the most stringent. The quality levels refer to production quality and not to the fitness for purpose of the manufactured product. NOTE Standards on joining of plastic pipes, fittings, valves and/or auxiliary equipment, and the assessment of the properties of the resulting joints are developed and maintained by ISO/TC 138.

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 method for determining the drawing and break characteristics of molten plastics. The method involves the measurement of the force generated in deforming a molten filament under defined extrusion temperature and drawing conditions. Data is generated under non-isothermal and non-homogeneous deformation conditions. However, it is useful for the interpretation of polymer behaviour in extensional flow. The method is suitable for thermoplastics moulding and extrusion materials that can be extruded using a capillary extrusion rheometer, or an extruder with capillary rod die or other extrusion devices and have sufficient melt strength to be handled without difficulty. The method is applicable to chemically stable materials that produce a uniform extrudate free from heterogeneities, bubbles, unmelted impurities, etc. This method can provide information on — processability for all extrusion techniques, — the effect of mechanical and thermal history, and — the effect of chemical structure, such as branching, entanglements and molecular mass. This technique is one of a number of techniques that can be used to measure the extensional flow behaviour of a material. This method of measurement does not necessarily reproduce the drawing conditions to which thermoplastics are subjected to during their processing.
