19、2:2007 (E) 4 Introduction Recycling of 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 environmental impact of recycli

20、ng 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 preferably be met: recycling sch

21、eme 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 designed to deliver recycla

22、ble 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 CEN on Environmental Aspe

23、cts 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 back each individual p

24、roduct 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 affect the products suitabi

Licensed Copy: Wang Bin, ISO/EXCHANGE CHINA STANDARDS, 22/04/2008 08:50, Uncontrolled Copy, (c) BSIEN 15342:2007 (E) 5 1 Scope This European Standard defines a method of specifying delivery condition characteristics for polystyrene (PS) recyclates. I

26、t gives the most important characteristics and associated test methods for assessing a single batch of PS recyclates intended for use in the production of semi-finished/finished products. It is intended to support parties involved in the use of recycled PS to agree on specifications for specific and

27、 general applications. This standard does not cover the characterisation of plastics wastes. See EN 15347. This standard is applicable without prejudice to any existing legislation. 2 Normative references The following referenced documents are indispensable for the application of this document. For

34、pean Standard, the terms and definitions given in EN ISO 472:2001 and CEN/TR 15353:2007 apply. The abbreviated terms are given in EN ISO 1043-1:2001. 4 Characterisation of PS recyclates A single batch is the quantity of recyclate that has homogeneous characteristics within the specified tolerances.

35、The characteristics of PS recyclates, which shall be determined for every batch of recyclate, are given in Table 1, and are divided into two types: Required characteristics, needed to define PS recyclates in general, and required for all recyclates. Optional characteristics, needed to define PS recy

36、clates according to customer specifications and applications. NOTE Polystyrene, or polystyrene-containing, plastics wastes for recycling may contain a variety of styrenic polymers, such as General Purpose (crystal or expanded) PS, and Impact-modified PS (usually containing grafted rubber particles).

37、 There may also be copolymers containing -methyl styrene, butadiene, isoprene, acrylonitrile etc., and there may even be other non-styrenic polymers. The properties and performance of recyclates derived from such wastes will depend on the relative proportions of those polymers. Some of these copolym

38、ers (MBS, SAN for example) are not miscible with polystyrene, and can have adverse effects on the recyclate properties. These characteristics shall be assessed using the test methods given in Table 1. Where possible, the supplier should provide information on the original application of the material

39、. A Certificate of Analysis, giving the test results for each batch of recyclate shall be provided by the supplier to the purchaser on request. The polystyrene content of the recyclate may be measured by a method agreed between the parties, who will also agree the required level of polystyrene. To s

40、ecure 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.

46、ls, processes and finished products. NOTE 1 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 batches of material shall be agreed between the supplier an

47、d the purchaser.

48、ethod available to supply such information. These records should be 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-mel

49、ting contaminants present in the recyclate. The statement of filtration level shall include details of the filter. Recyclates that have not passed through a melt process cannot be quantified in the same way, and the supplier may state this. NOTE 2 EN 15343 describes a qualified recycling process and gives details of traceability and the assessment of recycled content.
