ISO 899-2:2003 specifies a method for determining the flexural creep of plastics in the form of standard test specimens under specified conditions such as those of pretreatment, temperature and humidity. It applies only to a simple freely supported beam loaded at mid-span (three-point-loading test). The method is suitable for use with rigid and semi-rigid non-reinforced, filled and fibre-reinforced plastics materials (see ISO 472 for definitions) in the form of dumb-bell-shaped test specimens moulded directly or machined from sheets or moulded articles. NOTE The method may be unsuitable for certain fibre-reinforced materials due to differences in fibre orientation. The method is intended to provide data for engineering-design and research and development purposes. Data for engineering-design purposes requires the use of extensometers to measure the gauge length of the specimen. Data for research or quality-control purposes may use the change in distance between the grips (nominal extension). Flexural creep may vary significantly with differences in specimen preparation and dimensions and in the test environment. The thermal history of the test specimen can also have profound effects on its creep behaviour (see Annex A). Consequently, when precise comparative results are required, these factors must be carefully controlled. If flexural-creep properties are to be used for engineering-design purposes, the plastics materials should be tested over a broad range of stresses, times and environmental conditions. The method may not be suitable for determining the flexural creep of rigid cellular plastics (attention is drawn in this respect to ISO 1209-1, Cellular plastics, rigid -- Flexural tests -- Part 1: Bending test, and ISO 1209-2, Cellular plastics, rigid -- Flexural tests -- Part 2: Determination of flexural properties).

This document applies to unplasticized poly(vinyl chloride) (PVC-U) profiles that are intended to be used for the fabrication of windows and doors in accordance with the EN 14351 series or EN 16034, shutters according to EN 13659 and other construction profiles in accordance with the EN 13245 series. Furthermore, this document is also applicable for profiles used in other PVC-U products, which can include recyclates. This document gives references and specifies general and product-specific design for recycling principles. NOTE 1 In this document, the term “PVC-U profiles” is used to refer to construction profiles made from PVC-U, PVC-UE, and PVC-U-based natural fibre composites (NFC). Criteria for the use of materials, process conditions, and recyclability are defined, which are considered during the design process. This document defines principles to - obtain the highest possible share of recyclability of the PVC-U part in the profile, and - increase the share of PVC-U recyclate in the profile, while complying with requirements for the final product, where existent and defined elsewhere. This document establishes flowcharts which help to assess, (i) how recyclability is evaluated and (ii) whether inclusion of rPVC-U is possible. The following components of the final PVC-U construction product are considered in this document: - profiles; - reinforcements; - gaskets; - insulations; - coverings. This document specifies only the technical connection of the profile to other components (such as glazing or hardware) and their impact on the recyclability of the PVC-U profiles. The recyclability of the other components (e.g. glazing, aluminium cover, hardware) is excluded from this document. NOTE 2 Examples for profiles included in this document and their intended use can be found in Figure 1.

ISO 19252:2008 specifies a method for determining the scratch properties of plastics under defined conditions. The method involves making a scratch by moving a hard instrument (scratch tip) of specified geometry under specified conditions of load and speed across the surface of a test specimen and then assessing the result.

The method is used to investigate the behaviour of specified types of specimen under the scratch conditions defined and for classifying the type of scratch of specimens within the limitations inherent in the test conditions. It can also be used to determine comparative data for different types of material by means of a so‑called scratch map in which the types of scratch behaviour for each set of test conditions of test load and test speed are determined using the basic method of constant-load testing, and also by means of the so‑called critical normal load determined using an alternative method of linearly increasing load testing.

The method is suitable for use with uncoated and unlacquered thermoplastic moulding materials and thermosetting moulding materials.

The method specifies the preferred dimensions for the test specimen and the preferred scratch-tip geometry.

This International Standard describes two methods for the determination of free formaldehyde (HCHO) in polymerdispersions. The procedure has been evaluated using acrylic, acrylonitrile butadiene, carboxylated styrenebutadieneand vinyl acetate polymer dispersions. Both test methods may also be applicable to polymer dispersionsof other compositions.

Method A is the preferred method for polymer dispersions with a free-formaldehyde content higher than .

Method B is recommended if lower formaldehyde contents have to be determined or arbitration analyses have to becarried out.

Both methods minimize changes in free-formaldehyde concentration that can result from changes in the physical or chemical properties of polymer dispersions.

There are no known limitations to these methods when used in the manner described.
