Piping systems for alternative installation techniques
For more than six decades, plastic pipes have been used successfully in gas and drinking water supply, wastewater disposal, sanitary and heating installation as well as industrial plant engineering. The deciding factor in particular is the long lifetime of up to 100 years proven on basis of international standards.
Plastic pipes made of PE 100-RC offer a considerably higher resistance to slow crack growth in comparison to pipes made of PE 80 and PE 100. Due to their high stress cracking and point loading resistance, sand embedding is no longer mandatory for safe operation of these pipes. Instead, alternative installation techniques such as installation without sand em-bedding with reuse of excavated soil when laying in open trench can be used. Moreover, also methods of trenchless installation such as burst lining with associated economic benefits are applicable.
Development of PAS 1075
Already in 2009, when PAS 1075 was introduced, DIN CERTCO established the corresponding DINplus certification of pressure pipes made of PE 100-RC for alternative installation techniques according to PAS 1075:2009-04 "Pipes made from Polyethylene for alternative installation techniques - Dimensions, technical requirements and testing".
The theoretical knowledge and practical experience ob-tained in the past 10 years has been included in DIN CERTCO Certification Scheme Plastic Piping Systems (Pressure pipes and fittings), which uniquely reflects the current techno-logical and scientific status to assure highest quality and safety in this field.
This is why grid operators and planners, whether in Germany, in Europe or worldwide, rely on the DINplus certification of pressure pipes made of PE 100-RC for alternative installation techniques according to PAS 1075.
By means of DIN CERTCO Certification Database at www.dincertco.tuv.com , all valid certifications can be viewed transparently on a daily basis by using the keyword “PAS 1075”.
Testing and certification
Before granting a certification, an initial inspection of the production site is carried out by DIN CERTCO. Later on, the production site is inspected by DIN CERTCO twice a year. The inspection audit includes the inspection of production, laboratory, factory production con-trol and quality management as well as sampling of pipes for audit testing.
The type testing as well as the audit testing is carried out only by competent testing laboratories recognized by DIN CERTCO. The mandatory testing programme depends on the certified wall thickness range and includes testing of stress cracking behavior and point loading tests. For specific applications, penetration tests and scratch tests are also required. The involved testing laboratories have proven their competence on basis of a corresponding accreditation according to ISO 17025 and an extensive knowledge and experience in this field.
There are lots of good reasons for a DIN CERTCO-certification.
- Provide evidence of your superior quality
- Clearly set yourself apart in the competitive environment
- Help your customers make a decision by an international mark with high reputation
- As a neutral third party, DIN CERTCO backs up your quality assertions
- Provide evidence of tender requirements in the voluntary and legally obliged field
- Quicker market access for innovative products
- Control the quality of basic materials.
- Use of a strong international network of testing laboratories and cooperation partner like KRV and DVGW
