What is PD CEN/TS 18522Polypropylene (PP) plastics piping systems about?  

PD CEN/TS 18522 is a standard that discusses PP plastic piping systems. 

PD CEN/TS 18522 is the second part in the multi-series that is applicable to the plastics piping systems for non-pressure underground drainage and sewerage. It details best practices to establish efficient quality management systems for drainage and sewerage pipework. 

PD CEN/TS 18522 gives guidance for the assessment of conformity of materials, products, joints, and assemblies in accordance with the applicable part(s) of EN 1852 intended to be included in the manufacturer’s quality plan as part of the quality management system and for the establishment of certification procedures. 

In conjunction with EN 1852-1, this document is applicable to solid wall piping systems made of polypropylene (PP) is intended to be used for: 

  • Non-pressure underground drainage and sewerage outside the building structure (application area code “U”) 
  • Non-pressure underground drainage and sewerage for both buried in ground within the building structure (application area code “D”) and outside the building structure 

Note: The quality management system is expected to conform to or be no less stringent than the relevant requirements in EN ISO 9001. 

Note: If third-party certification is involved, the certification body is expected to be accredited to EN ISO/IEC 17065 [2] or EN ISO/IEC 17021, as applicable. 

Note: In order to help the reader, a basic test matrix is given in Annex A. 

Who is PD CEN/TS 18522PP plastics piping systems for?  

PD CEN/TS 18522 on PP plastics piping systems is useful for:  

  • Manufacturers and suppliers of PP pipes and fittings  
  • Construction industry   
  • Contractors   
  • Civil engineers   
  • Specifiers and installers   
  • Inspection bodies 
  • Certification bodies  
  • Testing laboratory 

Why should you use PD CEN/TS 18522PP plastics piping systems?  

PP plastic is a flexible, lightweight and corrosion-resistant piping product. These benefits make them an ideal option for a broad variety of applications such as potable water service or distribution lines, natural gas distribution, lawn sprinklers, sewers, waste disposal, and drainage lines.   

PD CEN/TS 18522 provides requirements on testing and inspection, materials, size and fitting groupings, and characteristics that require type-testing. As a result of the testing performed, you can prove that the material, product, joint or assembly is capable of conforming to the requirements given in the relevant standard. 

If you are a manufacturer, PD CEN/TS 18522 ensures the products and assemblies produced are based on a quality management system which includes a quality plan. Adhering to standard requirements and the resulting enhancement in quality management systems can help you demonstrate credibility of your products, further enabling entry to newer markets.
