New DIN standards for water pressure pipes recognise PP-RCT
During 2006, the German standards for polypropylene (PP) pressure pipes have been revised. The designations PP-H100, PP-B80 and PP-R80 have been withdrawn as they did not reflect the required behaviour at elevated temperatures and were changed to PP-H, PP-B and PP-R. Also, pioneering PP-RCT has now been officially recognised as a category under the new German standards DIN 8077 and DIN 8078 for PP pressure pipes. The creation of a new PP-RCT class means that these solutions can now be tested according to a widely accepted quality standard.
