This document establishes the terms, definitions, methodologies and calculations that are necessary for the recovery and recycling of waste from plastic products and materials labelled as industrially compostable through organic recycling. It 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. It 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. This 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 treatment technology used for recycling (whether it is 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.

This document defines a method for testing the low-temperature cracking index of thermosetting resin-based materials.

It is applicable to coloured PVC compounds and products where a discolouration test under the action of heat can be unsatisfactory. This document is applicable to compounded PVC materials and products. It can be applicable to polymers in powder form under appropriate conditions, depending on the agreement between the interested parties. This document does not apply to PVC compounds in the form of dry blends, since such materials might not be sufficiently homogeneous. This document does not apply to PVC compounds and products which evolve other decomposition products, in addition to hydrogen chloride, at elevated temperatures that can affect the conductivity of water when they are absorbed into it. NOTE In this case, ISO 182-4 [2] provides the suitable method for the determination of chloride ion (Cl−) in the absorbing solution. This document can also be applied to other plastics materials which can evolve hydrogen chloride or other hydrogen halides when heated under the conditions prescribed by the relevant specifications, or as agreed upon between the interested parties.

This document specifies three methods for the determination of the density of non-cellular plastics in the form of void-free moulded or extruded objects, as well as powders, flakes and granules. — Method A: Immersion method, for solid plastics (except for powders) in void-free form. — Method B: Liquid pycnometer method, for particles, powders, flakes, granules or small pieces of finished parts. — Method C: Titration method, for plastics in any void-free form. NOTE Density is frequently used to follow variations in physical structure or composition of plastic materials. Density can also be useful in assessing the uniformity of samples or specimens. Often, the density of plastic materials depend upon the choice of specimen preparation method. When this is the case, precise details of the specimen preparation method are intended to be included in the appropriate material specification. This note is applicable to all three methods. Annex C provides further information for calculating the volume of the specimen used for the determination of the density in the case that method A (the immersion method) is applied.

This document specifies a test method for the determination of puncture impact properties of a plastic film using instruments for measuring force and deflection. It is applicable if a force-deflection or force-time diagram, recorded at nominally constant striker velocity, is required for detailed characterization of the impact behaviour. This test method is also used when a small number of test specimens are available, and the staircase method described in the ISO 7765-1 cannot be applied. The test method is applicable to films of up to 1 mm thickness and makes it possible to compare impact-penetration forces, biaxial deformabilities and energy-absorption capacities of films. Also, the transition region between brittle and tough behaviour of the film under the conditions of testing can be determined by varying the temperature or the penetration velocity or the relative humidity.[ REF Reference_ref_7 \r \h 4 08D0C9EA79F9BACE118C8200AA004BA90B0200000008000000100000005200650066006500720065006E00630065005F007200650066005F0037000000 ]
