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 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 preferably 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 designed 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 CEN on Environmental Aspects and in accordance with CEN/TR 15353, Plastics—Recycled Plastics—Guidelines for the development of standards relating to 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 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 product's suitability for recycling into the intended application.

3 Terms, definitions and abbreviated terms For the purposes of this European Standard, the terms and definitions given in EN ISO 472:2001 and CEN/TR 15353:2007 and the following apply.
3.1 sieve retention percentage, in mass, of the recycled test sample retained on a sieve at the end of the test
3.2 container retention percentage of recycled material retained in the container at the bottom of a stack of sieves, or under a simple sieve, at the end of the testing method compared to the mass of the sample tested 3.3 average particulate dimension single value of size, expressed to the nearest 0, 001 mm, representing the dominant mass size for the whole test sample 3.4 tetrahydrofuran THF
tetrahydrofuran 4 Characterisation of PVC recyclates 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 recyclates.
 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.
