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 document specifies a test method for determining the leaktightness and the ease of operation of a valve made of thermoplastic material following an impact applied to the operating device. Additionally, a different procedure of the test on diaphragm valve can be specified by the valve manufacturer.

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.

This document specifies the main characteristics and associated test methods for assessing of acrylonitrile-butadiene-styrene (ABS) recyclates intended for use in the production of semi-finished/finished products. It is intended to support parties involved in the use of ABS recyclates (rABS) to agree on specifications for specific and generic applications. This document does not cover the characterization of plastics wastes, which is covered by the EN 15347 series, neither traceability topics which are covered by EN 15343.

This document defines a system for the classification of recycled plastics based on the available data depth (Data Quality Levels, DQL) and provides guidelines for the labelling of the recyclate type and recycled content in compounds. It is intended to support parties involved in the use and trading of recycled plastics, explicitly including digital trading platforms.

This document specifies the classifications, requirements and test methods for unplasticized poly(vinyl chloride) (PVC-U) profiles with thermo-laminated foils designed for external uses which are 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. NOTE 2 For the purpose of production control, test methods other than those specified in this document can be used.
