The relationship with ISO 161-1 published by
10、the International Organization for Standardization (ISO) is shown in Appendix A. DIN, the German Institute for Standardization, would like to bring attention to the fact that complying with this standard can involve exploitation of Patent EP1448631 in regard to material PP-RCT. DIN takes no postitio
11、n on the legitimacy, validity or scope of this patent. The holder of this patent has declared to DIN he is prepared to negotiate with applicants from any part of the world licences under reasonable and non-discriminatory business conditions as laid down in his declaration. The declaration of the hol
12、der of patent EP 1448631 is registered with DIN. Information can be obtained from the patent holder at this address: Att: Managing Director Borealis Technology Oy | P.O. Box 330 | FI-06101 Porvoo | Finland Tel. +358 9 3949 00 e-mail: Attention is drawn to the possibility that some of the elements o
13、f this document may be the subject of patent rights. DIN shall not be held responsible for identifying any or all such patent rights. Amendments This standard differs from DIN 8077:1999-07 as follows: a) The material designation has been amended (see Explanatory notes in Appendix A). b) Type PP-RCT
14、polypropylene has been included. c) The S/SDR series has been extended in the dimension and operating pressure tables. d) The operating pressure tables have been revised and corrected. e) The explanatory notes have been revised. This standard differs from DIN 8077:2007-05 as follows: a) A reference
15、to patent rights has been added to the Foreword. b) The description of PP-RCT polypropylene has been modified. c) A reference to existing European product standards has been added to the Scope. Previous editions DIN 8077: 1974-02, 1989-01, 1997-12, 1999-07, 2007-05 DIN 8077:2008-09 5 1 Scope This st
16、andard is applicable to pipes made from homopolymer polypropylene (PP-H), block copolymer polypropylene (PP-B), random copolymer polypropylene (PP-R) and random copolymer polypropylene with modified crystalline structure and elevated temperature resistance (PP-RCT) as specified in DIN 8078. Attentio
17、n is brought to the fact that existing European product standards apply for some specific applications, which are to be complied with where necessary. Some of these product standards are listed in the Bibliography for the information of users of this standard. Please note that because European Stand
18、ards are continually being developed, this list is not exhaustive. 2 Normative references The following referenced documents are indispensable for the application of this document.

22、ics. Since the impact strength of PP-H decreases as the temperature increases, the safety factors have been classified as a function of the temperature.
