What is PD CEN/TS 17627 about?
PD CEN/TS 17627 specifies a method for determination by melt filtration of solid contaminants content in a sample of recycled thermoplastic material, evaluating their number and, optionally, their size and substance (material).
Who is PD CEN/TS 17627 for?
PD CEN/TS 17627 on solid contaminants in recycled plastics is relevant to:
- Plastic manufacturing industries
- Plastic recycling companies
- Suppliers and buyers of recycled plastic
Why should you use PD CEN/TS 17627?
The use of recycled materials in the production of plastics products is widely accepted throughout industries. Those recycled materials are mostly prepared from post-industrial or post-consumer sources, which always contain more or less contamination by foreign bodies. Most of this contamination is removed during the recycling process, either by washing and/or by melt filtration.
In this regard, PD CEN/TS 17627 specifies the determination of solid contaminants content in recycled plastic through procedures that involve extrusion and flattening. The level of contamination can then be rated based on the number of foreign bodies and percentage of screen blocked. The rating levels as per these criteria are provided in PD CEN/TS 17627.
PD CEN/TS 17627 plays a vital role in identifying not only the level of contaminants but also the type of contaminants, the designation for which has been tabulated.
Standardising processes to assess recycled plastic in compliance with PD CEN/TS 17627, will help make improved choices regarding the components and materials used in end products, thereby maintaining consistency in quality control.
