This European Standard defines a method of specifying delivery condition characteristics for polystyrene (PS) recyclates. It 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 general applications. This standard does not cover the characterisation of plastics wastes. See prEN 15347. This standard is applicable without prejudice to any existing legislation.
