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, for flexible and rigid cellular polymeric materials, laboratory procedures which are intended to imitate the effects of naturally occurring reactions such as oxidation or hydrolysis by humidity. The physical properties of interest are measured before and after the application of the specified treatments. Test conditions are only given for open cellular latex, both open- and closed-cell polyurethane foams, and closed-cell polyolefin foams. Conditions for other materials will be added as required. The effect of the ageing procedures on any of the physical properties of the material can be examined, but those normally tested are either the elongation and tensile properties, or the compression or indentation hardness properties. These tests do not necessarily correlate either with service behaviour or with ageing by exposure to light. If desired, the ageing conditions contained in this document can be applied to composite structures containing any of the above types of cellular material. This can be helpful in the investigation of possible interactions between cellular materials and other substrates. Composite constructions can be in the form of complete finished products or representative small specimens cut there-from.

Covers the determination of material with a density up to 250 kg/m3. It also indicates a method for the calculation of the compression stress value of such materials. The compression stress/strain characteristic is a measure of the load-bearing properties of the material. Two formulas allow to calculate the results. Part 2 refers to high density materials. Constitutes a minor revision of the first edition (ISO 3386-1-1979).

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.
