DIN EN 15346:2015-01 EN 15346:2014(E)5 Introduction Recycling of plastics waste is one type of material re

27、covery process intended to save resources (virgin raw materials, water, and energy), while minimizing 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 th

28、e 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 alternat

29、ive 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 recyclin

30、g technologies and with the (changing) needs of the identified market outlets, preferably at minimum costs to society. This European Standard has been produced in accordance with the guidance produced by CEN on Environmental Aspects and in accordance with CEN/TR 15353. NOTE CEN/TR 15353 considers th

31、e 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 correctly through its life. Consequently products are out of industrial control for a period

32、of time. It is possible that during this period contamination with other materials might occur that could affect the products suitability for recycling into the intended application. DIN EN 15346:2015-01 EN 15346:2014(E)6 1 Scope This European Standard defines a method of specifying delivery conditi

33、ons for poly(vinyl chloride) (PVC) recyclates. It gives the most important characteristics and associated test methods for assessing of PVC recyclates intended for use in the production of semi-finished/finished products. It is intended to support parties involved in the use of recycled PVC to agree

34、 on specifications for specific and generic applications. This European Standard does not cover the characterization of plastics wastes. See EN 15347. This European Standard is applicable without prejudice to any existing legislation. 2 Normative references The following documents, in whole or in pa

46、es A single batch is the quantity of recyclate that has homogeneous characteristics within the specified tolerances. The characteristics of PVC recyclates, given in Table 1, are divided into two types: required characteristics needed to characterize PVC recyclates in general, and required for all re

47、cyclates; optional characteristics needed to characterize PVC recyclates according to customer specifications and applications. These characteristics shall be assessed by using the test methods given in Table 1. A certificate of analysis giving the test results for each batch of recyclates shall be

48、provided by the supplier to the purchaser upon request. NOTE Typical compositions of PVC compounds are given in Annex A. DIN EN 15346:2015-01 EN 15346:2014 (E) 8 The supplier shall provide the necessary information about the material composition of the recyclates, as specified by the purchaser or required by the applicable regulations.
