Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard replaces CJ/T 250-2007 "High Density Polyethylene (HDPE) Pipe and Fittings for Building Drainage", from the date of implementation of this standard CJ/T 250-2007 is abolished. Compared with CJ/T 250-2007, the main technical changes except editorial changes are as follows. --- Increase the normative reference document GB/T 18992.2 (see Chapter 2); --- Replace EN1053.1995 and EN1054.1995 with GB/T 5836.1 (see Chapter 2); --- Increase the English translation of the term (see 3.1); --- Increase PE compounding (see 3.1.2); --- Increased the basic performance of "PE100" (see 4.1); --- Modified the icon and dimensions of Soweto (see 5.2.1); --- Modify the scope of compliance with EPDM (see 5.2.5); --- Increase the out-of-roundness of the pipe (see 6.3.1.4); --- Increase the vacuum test requirements in Table 8 (see 6.4) --- Added H-connector diagram and dimensions (see B.19); --- Increased the illustration and size of the riser vent cap (see B.19); --- Added P-type trap shape and size (see B.20); --- Added S-type trap illustration and size (see B.21); --- Increased impact strength test (see Appendix D); --- Increased weld strength test (see Appendix E). This standard practical redrafting method is modified to adopt ISO 8770.2003 "plastic pipes for sewage discharge (low temperature and high temperature) in buildings) System---polyethylene (PE), the degree of consistency between this standard and ISO 8770.2003 is non-equivalent. Compared with ISO 8770.2003, the technical differences between this standard and ISO 8770.2003 are as follows. ---ISO 8770.2003 high-density polyethylene pipes and fittings for building drainage are connected by butt welding, electrofusion and Socket connection, etc. The connection methods adopted in this standard are mainly butt welding and electrofusion, and the socket connection is only suitable for expansion and extension. Snap and seal adapters. --- For the application range of high-density polyethylene pipe for building drainage, this standard specifies the discharge of sewage, wastewater and rainwater from buildings. application. This standard was proposed by the Institute of Standardization of the Ministry of Housing and Urban-Rural Development. This standard is under the jurisdiction of the Building Water Supply and Drainage Standardization Technical Committee of the Ministry of Housing and Urban-Rural Development. This standard is mainly drafted by. Shanghai Jiboli Housing Sanitary Equipment Engineering Technology Co., Ltd., Shanghai Architectural Design and Research Institute Co., Ltd. Division, Shanghai Minghao Technology Industrial Co., Ltd., Xidi International Design Consultant (Shenzhen) Co., Ltd., Zhejiang Weixing New Building Materials Co., Ltd.
