CEN/TC 249/SC 1/WG 5 - Physical, chemical and rheological properties

This document specifies general conditions for the analysis of polymers using thermogravimetric techniques. It is applicable to liquids or solids. Solid materials can be in the form of pellets, granules or powders. Fabricated shapes reduced to appropriate specimen size can also be analysed by this method.
This document establishes methods for the investigation of physical effects and chemical reactions that are associated with changes of mass.
This document can be used to determine the temperature(s) and rate(s) of decomposition of polymers, and to measure at the same time the amounts of volatile matter, additives and/or fillers they contain.
This document is applicable to measurements in dynamic mode (mass change versus temperature or time under programmed temperature conditions) or isothermal mode (mass change versus time at constant temperature).
This document is applicable to measurements at different testing atmospheres, such as separation of decomposition in an inert atmosphere from oxidative degradation.

This document defines the general conditions for the determination of the reduced viscosity, intrinsic viscosity and K‑value of organic polymers in dilute solution. It defines the standard parameters that are applied to viscosity measurement.
This document is used to develop standards for measuring the viscosities in solution of individual types of polymer. It is also used to measure and report the viscosities of polymers in solution for which no separate standards exist.

This European Standard establishes a system of designation for profiles made of unplasticized poly(vinyl chloride) (PVC-U) intended to be used for building applications.
This part is applicable to light coloured and coloured PVC-U profiles, obtained by a mono-extrusion or a co-extrusion process, with or without a laminated foil or with a lacquered-coating.
It specifies test methods and test parameters.
This method of designation is intended to be used in product specification when the application is specified.
NOTE   It is recommended to use this method for the designation of PVC-U profiles for information related to technical literature of the manufacturer, not for the marking of the products.
Profiles for the management of electrical power cables, communication cables and power track systems used for the distribution of electrical power, profiles for windows or doors and profiles for guttering are not covered by this European Standard.

This European Standard establishes a system of designation for profiles made of cellular unplasticized poly(vinyl chloride) (PVC-UE) intended to be used for building applications.
This part is applicable to light coloured and coloured mono-extruded PVC-UE profiles, co-extruded profiles consisting of a core made of PVC-UE and a skin layer of non-cellular unplasticized poly(vinyl chloride)
(PVC-U), and PVC-UE profiles with laminated foil or lacquered-coating.
It specifies test methods and test parameters.
This method of designation is intended to be used in product specification when the application is specified.
NOTE   It is recommended to use this method for the designation of PVC-UE profiles for information related to technical literature of the manufacturer, not for the marking of the products.
Profiles for the management of electrical power cables, communication cables and power track systems used for the distribution of electrical power, profiles for windows or doors and profiles for guttering are not covered by this European Standard.

ISO 11358-1:2014 specifies general conditions for the analysis of polymers using thermogravimetric techniques. It is applicable to liquids or solids. Solid materials may be in the form of pellets, granules or powders. Fabricated shapes reduced to appropriate specimen size may also be analysed by this method.

This International Standard specifies two test methods for determining the refractive index of plastics, namely:
Method A: a refractometric method for measuring the refractive index of moulded parts, cast or extruded sheet
or film, by means of a refractometer. It is applicable not only to isotropic transparent, translucent, coloured or
opaque materials but also to anisotropic materials. The method is recommended when great accuracy is
required. It is not applicable to powdered or granulated material.
Method B: an immersion method (making use of the Becke line phenomenon) for determining the refractive
index of powdered or granulated transparent materials by means of a microscope. Monochromatic light should,
in general, be used to avoid dispersion effects. The accuracy of this method is about the same as that of
method A. It is applicable to isotropic translucent, coloured materials but is not applicable to opaque materials
nor to anisotropic materials.
NOTE 1 The refractive index is a fundamental property which can be used for checking purity and composition, for the
identification of materials and for the design of optical parts. The change in refractive index with temperature may give an
indication of transition points of materials.
NOTE 2 The accuracy of method B is approximately the same as that of method A when an experienced operator uses the
method with extreme care (see clause 7).

ISO 1628-1:2009 defines the general conditions for the determination of the reduced viscosity, intrinsic viscosity and K‑value of organic polymers in dilute solution. It defines the standard parameters that are applied to viscosity measurement, and can be used to develop standards for measuring the viscosities in solution of individual types of polymer. It can also be used to measure and report the viscosities of polymers in solution for which no separate standards exist.

Deals with the determination of the total luminous transmittance, in the visible region of the spectrum, of planar transparent and substantially colourless plastics, using a single-beam photometer with a specified CIE standard light source and photodetector. Does not apply to plastics which contain fluorescent substances.

IEC 61747-2-1:2013 serves as a Blank Detail Specification (BDS) for a high quality approval system and contains requirements for style and layout and minimum content of detail specifications. These requirements are applicable when the detail specification is published (e.g. for standard product). This second edition of IEC 61747-2-1 cancels and replaces the first edition published in 1998, and constitutes a technical revision. The main changes from the previous edition are as follows:
- several words and test conditions were added in Clause 7 and Clause 8;
- the new edition was editorially changed according to the current ISO/IEC Directives - Part 2.
