Defines a system for sampling procedures for testing plastics waste and recyclates which take into account the specifics of the plastics waste and recyclates.

This Technical Specification specifies a system for sampling procedures for testing plastics waste and recyclates which take into account the specifics of the plastics waste and recyclates. It is intended to cover all stages of the plastic recycling process.

The sampling procedures include the statistical specifics of the plastic waste and the behaviour of recyclates.

The sampling method should produce a representative testing sample. Differences can arise due to:

• the mixture of plastics;

• the origin (e.g. green dot in Germany, or electronic/automotive industry);

• the previous use of the plastic material;

• the residual contents (e.g. of containers);

• inert, residual or moisture content on or in the material.

This Technical Specification is without prejudice to any existing legislation.
