1.1 This part of ISO 527 specifies the test conditions for determining the tensile properties of moulding and extrusion plastics, based upon the general principles given in ISO 527-1.

1.2 The methods are selectively suitable for use with the following range of materials in the preferred thickness, or, in case of specimen machined from molded parts in the thickness as molded:

— rigid and semi-rigid thermoplastics moulding, extrusion and cast materials, including compounds filled and reinforced by, for example, short fibres, small rods, plates or granules but excluding textile fibres (see ISO 527-4 and ISO 527-5). See ISO 527-1:2019, Clause 3 for the definition of "rigid" and "semi-rigid".

— rigid and semi-rigid thermosetting moulding and cast materials, including filled and reinforced compounds but excluding textile fibres as reinforcement (see ISO 527-4 and ISO 527-5);

— thermotropic liquid crystal polymers.

The methods are not normally suitable for use with rigid cellular materials or sandwich structures containing cellular material. For rigid cellular materials see ISO 1926. The methods are not suitable for flexible films and sheets, of thickness smaller than 1 mm, see ISO 527-3.

1.3 The methods are applied using specimens which may be either moulded to the chosen dimensions or machined, cut or punched from injection- or compression-moulded plates. The multipurpose test specimen is preferred (see ISO 20753).

This document provides a process that manages the identification of the level of compatibility of plastic packaging features with collection, sorting and recycling, describing the level of compatibility as fully, limited, and not recyclable. This standard covers any plastic packaging where the main body is made of plastic material. It targets to harmonize the design for recycling standard approach for each resin.

This document covers the design of PET bottles with respect to compatibility of the design with the collecting, sorting, and recycling processes. Packaging constituents and packaging components made of other materials than PET are also covered by this standard as they need to be evaluated on compatibility with polymer recycling.

This document covers the design of PET rigid packaging (except bottles) with respect to compatibility of the design with the collecting, sorting, and recycling processes. Packaging constituents and packaging components made of other materials than PET are also covered by this standard as they need to be evaluated on compatibility with polymer recycling.

This document is an input for a standard on the recyclability evaluation process of plastic packaging with respect to compatibility of the design with the collecting and sorting processes for the plastic used. This document covers any household plastic packaging where the main body is made of PET, PE, PP or PS material.

This document establishes the terms, definitions, methodologies, and calculations that are necessary for the recovery of waste from plastic products and materials labelled as industrially compostable (hereafter referred to as compostable plastic waste) through organic recycling. The document identifies the different types of organic recycling technologies used in the recovery and subsequent recycling of industrially compostable plastics waste arising from pre-consumer and post-consumer sources. This document also establishes the requirements and calculations to be considered in evaluating organic recycling inputs and outputs and determining output classifications for the recycling operation and the downstream integration points.

The document also outlines general quality requirements to be applied in all steps of the recovery process, and provides general recommendations for inclusion in material standards, test standards and product specifications. The process stages, requirements, recommendations, and terminology presented in this document are intended to be of general applicability.

This document does not establish test methods and criteria for the definition of the organic recyclability (e.g. compostability) of plastic materials and products.

This document refers to plastic waste deriving from products that have been classified as suitable for recovery through organic recycling by the relevant reference standards (e.g., ISO 17088, ISO 18606) and therefore labelled as industrially compostable. These products are generally called “industrially compostable” (e.g. compostable bag, compostable tableware) meaning “suitable for organic recycling”, independently of the final treatment technology (whether it is true aerobic composting, or a combination of anaerobic digestion and composting, or only anaerobic digestion).

This document does not address home composting because this gardening practice cannot be classified as recycling.

ISO 5659 specifies a method of measuring smoke production from the exposed surface of specimens of materials or composites. It is applicable to specimens that have an essentially flat surface and do not exceed 25 mm in thickness when placed in a horizontal orientation and subjected to specified levels of thermal irradiance in a closed cabinet with or without the application of a pilot flame. This method of test is applicable to all plastics. It is intended that the values of optical density determined by this test be taken as specific to the specimen or assembly material in the form and thickness tested and are not to be considered inherent, fundamental properties. The test is intended primarily for use in research and development and fire safety engineering in buildings, trains, ships, etc. and not as a basis for ratings for building codes or other purposes. No basis is provided for predicting the density of smoke that can be generated by the materials upon exposure to heat and flame under other (actual) exposure conditions. This test procedure excludes the effect of irritants on the eye.
