The pipes and fittings of Interplast exceed the requirements set by the European standards EN, universally accepted German standards DIN, Spanish UNE, British BS and American ASTM. As a result, pipes and fittings never show no deviation from the specifications in the regular biannual tests carried out official institutes on random samples from production and the warehouse space.
The outcome of all this is that The pipes and fittings of Interplast have product certification from the following organizations covering a total of more than 25 certificates.
- TUV Germany for the Quality Management System EN ISO 9001: 2008.
- EVETAM Greece for the physical and mechanical properties of pipes PE-X, PP-H, PVC and PP-R. It involves sizing of pipes and fittings, measuring the degree of networking for PEX pipes, microscopic homogenisation check, impact tests, testing under pressure at various temperatures and checking linear expansion.
- SKZ Germany for physical and mechanical properties of pipes PE-X, PE-MDX, PE-RT, PB, PP- H and PP-R. Moreover sewer pipes PP-H feature fireproofing certificate. It involves sizing of pipes and fittings, measuring the degree of networking for PEX pipes, microscopic homogenisation check, impact tests, testing under pressure at various temperatures and checking linear expansion.
- SKZ Germany for physical and mechanical properties of PP-R accessories.
- AENOR Spain for firefighting PP-R system
- CSA Canada for physical and mechanical properties of pipes PE-X, as for the suitability for drinking water.
- MPA-NRW Germany for oxygen permeability of Como-Pex pipes and Como-Floor Oxygen Barrie
- WRAS-NSF Great Britain for suitability of pipes PE, PEX and PP-R in drinking water.
While the pipes are periodically tested by the laboratories of ELOT in terms of mechanical strength and the State General Laboratory for suitability for drinking water
