This European Standard specifies the classifications, requirements and test methods for non-covered unplasticized poly(vinyl chloride) (PVC-U) profiles intended to be used for the fabrication of windows and doors. NOTE 1 For editorial reasons in this document the term "window" is used for window/door.

This document specifies a gradient column method for the determination of the density of non-cellular moulded or extruded plastics or pellets in void-free form. Density gradient columns are columns containing a mixture of two liquids, the density in the column increasing uniformly from top to bottom. NOTE Density is frequently used to follow variations in physical structure or composition of plastic materials. Density can also be useful in assessing the uniformity of samples or specimens. The density of plastic materials can depend upon the choice of specimen preparation method. When this is the case, precise details of the specimen preparation method are intended to be included in the appropriate material specification.

This document specifies a method for the determination of the penetration temperature of thermoplastics using thermomechanical analysis (TMA).

NOTE This method can also be used to measure the softening point.

This International Standard give guidelines for the inspection, recording procedures, packaging and storage of products, assemblies and components made from vulcanized or thermoplastic rubber prior to being put into circulation.

It is applicable to both solid and cellular rubber products prepared from dry raw rubber, latex or other sources. It is subject only to the requirements or recommendations of product specifications in which details of storage requirements for specific products are given. This standard is not intended for use with raw rubber in bale, liquid (solution or emulsion) or particulate form, storage guidance for which is given in ISO 7664.

The recommendations for packaging form an integral part of the controlled storage procedure, as well as providing means of identifying the material and product.

This document specifies methods for determining the amount of sulfur volatilized from vulcanized rubber under heating conditions using high performance liquid chromatograph (HPLC). The methods apply only to the sulfur which chemical formula is S8. The methods cannot be used above the thermal decomposition temperature of the rubber. Note 1 This methods determine the amount of sulfur that volatilizes from the vulcanized rubber under heating conditions, and do not determine the total amount of sulfur that can volatilize from the vulcanized rubber. Note 2 Depending on the method adopted to collect sulfur volatilized from vulcanized rubber, the test results can be different between the two methods.

This document specifies a method for exposing specimens made from poly(vinyl chloride) (PVC) based profiles to xenon-arc radiation, in order to assess changes in characteristics. It is applicable to PVC based profiles including those covered with foil, paint, thermo-laminated foils or coextruded.

NOTE The determination of changes in colour and variations of properties after exposure of PVC based profiles to xenon-arc radiation is described in an informative Annex A.

This document specifies methods for determining the amount of sulfur compounds volatilized from vulcanized rubber under heating conditions using gas chromatograph (GC) or ion chromatograph (IC). The methods apply to the sulfur compounds which are hydrogen sulfide (H2S), carbonyl sulfide (COS), carbon disulfide (CS2) and sulfur dioxide (SO2). The methods cannot be used above the thermal decomposition temperature of the rubber. Note The methods determine the amount of sulfur compounds that volatilize from the vulcanized rubber under heating conditions, and do not determine the total amount of sulfur compounds that can volatilize from the vulcanized rubber.
