EN 15344:2007 (E) 4 Introduction Recycling plastics waste is one type of material recovery 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 envir
20、onmental impact of recycling has to be assessed over the whole life cycle of the recycling system (from the 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 prefer
21、ably be met: recycling scheme being contemplated should generate lower environmental impacts than alternative 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 d
22、esigned to deliver recyclable plastics waste fractions fitting reasonably well with the available recycling 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
23、 CEN on Environmental Aspects and in accordance with CEN/TR 15353, Plastics Recycled plastics Guidelines 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
24、back each individual product at the end user stage and to check whether the product has been used correctly 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 affec
25、t the products suitability for recycling into the intended application. EN 15344:2007 (E) 5 1 Scope This European Standard defines a method of specifying delivery conditions for polyethylene (PE) recyclates. It gives the most important characteristics and associated test methods for assessing PE rec
26、yclates 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 standa
27、rd does 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.

34、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 homogeneous characteristics within the specified tolerances. The characteristics of PE recyclates, whi
35、ch 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 for all recyclates. Optional characteristics, needed to define PE recyclates according to cust
36、omer 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 PE-HD (high density polyethylene), PE-LD (low density polyethylene), PE-LLD (linear low dens
37、ity 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 scope of this Standard to investigate such relations. These characteristics shall be assessed by
38、 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 shall be provided by the supplier to the purchaser upon request. To secure the legal use of th
39、e 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: - Polymeric matrix, consisting of polyethylene (PE content); - Fillers, pigments and additives; -
40、 Impurities or contamination in a quantity which do not compromise the workability characteristics of PE (R); - Polymers compatible with the polymeric matrix.

47、ied out, including incoming materials, processes and finished products. EN 15344:2007 (E) 8 NOTE A quality management system certified to EN ISO 9001 may be a suitable guarantee of consistent recyclate quality. The specification and the standard deviation or range of values within and between batche
48、s of material shall be agreed between the supplier and the purchaser. Where a statement of recycled content, or the previous history of the material is requested, documentary evidence shall be provided, where there is no analytical method available to supply such information. These records should be
49、 available to the purchaser on request. Where a recyclate has been produced via a melt process, the supplier may choose to state the level of filtration applied during that process. This will determine the maximum size of any non-melting contaminants present in the recyclate. The statement of filtration level shall include details of the filter. Recyclates which have not passed through a melt process cannot be quantified in the same way, and the sup
