21、ecovery process intended to save resources (virgin raw materials, water, and energy), while minimising harmful emissions into air, water and soil as well as any impacts on human health. The environmental impact of recycling has to be assessed over the whole life cycle of the recycling system (from t

22、he waste generation point to the disposal of final residues). To ensure that recycling constitutes the best environmental option for treating the available waste, some prerequisites should preferably be met: recycling scheme being contemplated should generate lower environmental impacts than alterna

23、tive recovery options; existing or potential market outlets should be identified that will secure a sustainable industrial recycling operation; collection and sorting schemes should be properly designed to deliver recyclable plastics waste fractions fitting reasonably well with the available recycli

24、ng technologies and with the (changing) needs of the identified market outlets, preferably at minimum costs to society. This standard has been produced in accordance with the guidance produced by CEN on Environmental Aspects and in accordance with CEN/TR 15353, Plastics Recycled plastics Guidelines

25、for the development of standards for recycled plastics. NOTE CEN/TR 15353 considers the general environmental aspects which are specific to the recycling process. It is often impossible to trace back each individual product at the end user stage and to check whether the product has been used correct

26、ly through its life. Consequently products are out of industrial control for a period of time. It is possible that during this period contamination with other materials may occur that could affect the products suitability for recycling into the intended application.

It gives the most important characteristics and associated test methods for assessing PE recyclate

28、s intended for use in the production of semi-finished/finished products. It is intended to support parties involved in the use of recycled PE to agree on specifications for specific and generic applications. This standard is applicable without prejudice to any existing legislation. This standard doe

29、s not cover the characterisation of plastics wastes. See EN 15347. 2 Normative references The following referenced documents are indispensable for the application of this document.

36、r the purposes of this European Standard, the terms and definitions given in EN ISO 472:2001 and CEN/TR 15353:2007 apply. The abbreviated terms related to recyclates are given in EN ISO 1043-1:2001. 4 Characterisation of PE recyclates A single batch is the quantity of PE recyclate that has homogeneo

37、us characteristics within the specified tolerances. The characteristics of PE recyclates, which shall be determined for every batch (see ISO 3534-2) of recyclate, are given in Table 1, and are divided into two types: Required characteristics, needed to define PE recyclates in general, and required f

38、or all recyclates. Optional characteristics, needed to define PE recyclates according to customer specifications and applications. NOTE 1 Polyethylene plastics waste originate from different types or grades of PE containing additives to modify characteristics. Polyethylene is generally classified as

39、 PE-HD (high density polyethylene), PE-LD (low density polyethylene), PE-LLD (linear low density polyethylene) and others of less common use. The properties and performance of recyclates derived from such wastes may depend on the type or relative proportions of blends of PE, but it is not in the sco

40、pe of this Standard to investigate such relations. These characteristics shall be assessed by using the test methods given in Table 1. Where possible the supplier should provide information on the original applications. A certificate of analysis, giving the test results for each batch of recyclate s

41、hall be provided by the supplier to the purchaser upon request. To secure the legal use of the recyclate, the supplier shall provide the necessary information about the material composition of the recyclate, as specified by the purchaser. NOTE 2 In this European Standard, PE (R) is composed of: - Po

42、lymeric matrix, consisting of polyethylene (PE content); - Fillers, pigments and additives; - Impurities or contamination in a quantity which do not compromise the workability characteristics of PE (R); - Polymers compatible with the polymeric matrix.
