This document establishes requirements and specifications of the polyester moulding compounds BMC (bulk moulding compound) and DMC (dough moulding compound) with or without thickening agents. BMC and DMC are different types of preimpregnated product used for the production, by moulding, of various parts made of composite materials.

It is applicable to BMC and DMC. The scope is not limited to types of fibres and resins.

This document specifies two methods for the determination of co-monomer contents of polyethylene products by solution state 13C-NMR spectrometry (nuclear magnetic resonance spectrometry):

—   method A: inverse gated decoupling method.

—   method B: insensitive nuclei enhanced by polarization transfer method;

This document is applicable to copolymers of ethylene having a content of other 1-olefinic monomers of less than a mass fraction of 50 %.

This document is not applicable to ethylene homopolymers or copolymers in which ethylene is polymerized with two or more type 1-olefin comonomers.

This document specifies a method for determining the effect of heat on unplasticized poly(vinyl chloride) (PVC-U) profiles, to be carried out in air at 150 °C. It is also applicable to PVC-based profiles at specified temperatures/test conditions.

This document specifies a tensile bending method and a compression bending method for determining the failure stress of welded corners and welded T-joints made from unplasticized poly(vinyl chloride) (PVC-U) profiles. It is applicable to PVC based profiles used for the fabrication of windows and doors.

This document specifies the general “design for recycling” guidelines for EPS raw materials. It provides guidance on the impact of specific design characteristics on the recyclability of the product in practice and recommended design options to ensure that the product is recyclable, including target values and performance ranges, where applicable. It also provides a definition of recyclable product and of design for recycling. This document refers to the recycling processes of EPS products. The sorting and collecting steps are not part of this document. This document takes into account all currently known processes that are suitable to enable the circular economy for insulation materials. Particular attention is paid to ensuring that the most energy-efficient processes are given preference, especially mechanical recycling, unless reuse is already ruled out. For some of these processes, practical experience has been gained over many years, so a basic knowledge base for the development of a guideline is already available. At the same time, it is important to also take into account future-oriented processes, for which at the moment little but increasing experience is available or which have so far only been implemented on a small scale.

The ISO 10350 series identifies specific test procedures for the acquisition and presentation of comparable data for certain basic properties of plastics. In general, each property is specified by a single experimental value, although in certain cases properties are represented by two values obtained under different test conditions. The properties included are those presented conventionally in manufacturers' data sheets. ISO 10350-1 applies predominantly to unreinforced and reinforced thermoplastic and thermosetting materials that may be injection- or compression-moulded or prepared as sheets of specified thickness. For the purposes of ISO 10350-1, long-fibre-reinforced plastics are considered to have fibre lengths greater than 7,5 mm prior to moulding. NOTE ISO 10350-2 deals specifically with long- or continuous-fibre-reinforced plastics.

This document specifies the integrated management of agricultural plastic products with agronomic performance. This document gives guidance and requirements for their installation, use, removal, sorting, collection and preparation for recycling as well as general guidelines for design for recycling. NOTE 1 prEN 13206 , prEN 13207 , prEN 13655 , prEN 14932 and prEN 17098 1 include a specific clause dedicated to design for recycling. NOTE 2 Design for recycling for products not covered by a standard is detailed in this document. This document first aims professional users and can be used also for domestic purposes. This document applies to: - covering films that comply with EN 13206:2017+A1:2020 or with specifications laid out by the film manufacturer/supplier, used for covering greenhouses, small tunnels or livestock buildings, as well as to direct crop covers used for semi-forcing plants and seed; - silage films for horizontal silos that comply with EN 13207 or with specifications laid out by the film manufacturer/supplier; - sheaths for horizontal silos (forage crop and grain storage) that comply with EN 13207 or with specifications laid out by the sheath manufacturer/supplier; - stretch films for wrapping bales that comply with EN 14932 or with specifications laid out by the film manufacturer/supplier; - thermoplastic mulching films that comply with EN 13655 or with specifications laid out by the film manufacturer/supplier; - barrier films for agricultural and horticultural soil disinfection by fumigation comply with EN 17098 1; - nets and twines for catling and horticulture that comply with the specifications laid out by EN ISO 4167 or by the manufacturer/supplier; - flexible ducts, semi-rigid and rigid pipes and fittings for irrigation that comply with ISO 8779, EN ISO 9261, ISO 13460 1, ISO 16438, EN 14267, EN 12324 2, EN 13635, EN 13997, EN 17176 2:2019+A1:2022 or with specifications laid out by the manufacturer/supplier; - fabrics and non-woven nets and sheets for catling and horticulture that comply with ISO 9073 series or with specifications laid out by the manufacturer/supplier. This document does not cover construction, packaging and food-contact products. NOTE 3 For products non-suitable for recycling in the context of this document, specific procedures apply.

This document provides information and general guidance on the selection and use of the methods of exposure to solar radiation described in detail in subsequent parts of ISO 877.

These methods of exposure to solar radiation are applicable to plastics materials of all kinds as well as to products and portions of products.

It also specifies methods for determining radiant exposure. It does not include direct weathering using black-box test fixtures, which simulate higher end-use temperatures in some applications.

NOTE ASTM G7 and ASTM D4141 describe black-box exposure tests.

 This document specifies methods to determine changes in colour and other appearance properties, and variations in mechanical or other properties, of plastics that have been exposed to glass-filtered solar radiation, to natural weathering or to simulated solar radiation from a laboratory source.

The procedure used to analyse data depends on whether the test used to characterize the materials being exposed is destructive or non-destructive. The exposures are conducted under conditions described in specific exposure standards.

This document specifies the minimum values for expected strength as a function of time and temperature in the form of reference lines, for use in calculations on polyphenylsulfone (PPSU) injection moulded fittings.

Note A conservative approach has been taken by basing the analysis on the activation energy for polyolefins, 110 kJ/mol, for Hot and Cold-water applications. If experimental evidence can be given that other extrapolation time factors are justified, these may be used instead of the factors given in Table 1 of ISO 9080:2012.

 This document specifies a method for the direct exposure of plastics to solar radiation (method A) and a method for the exposure of plastics to glass-filtered solar radiation (exposure behind window glass) (method B). The purpose is to assess property changes produced after specified stages of such exposures. General guidance concerning the scope of ISO 877 is given in ISO/DIS 877-1:2024, Clause 1.
