Foreword

GB/T 18742 "hot and cold water with polypropylene pipe system" is divided into three parts. --- Part 1. General principles; --- Part 2. Pipe; --- Part 3. Pipe fittings. This section GB/T 18742 Part 1. This section drafted in accordance with GB/T 1.1-2009 given rules. This section replaces GB/T 18742.1-2002, compared with GB/T 18742.1-2002, in addition to editorial changes outside the main technical changes as follows. --- Increased the following terms and definitions. Tolerance (3.1.14), the calculated value of the tube series (3.1.16), design pressure (3.2.2), the maximum allowable Allowable working pressure (3.2.3), hydrostatic stress (3.2.4), cold water temperature (3.2.8), treated water for heating systems (3.2.9), design Stress (3.3.3), Polypropylene (3.3.4), Tubing with barrier (3.3.5); --- Added PP-RCT acronyms (see 4.2); --- Increased polypropylene pipe and fittings with other ingredients of the other requirements (see 6.1.5); --- Increased PP-RCT prediction strength reference curve (see Appendix A). This section uses the redrafted law to amend the use of international standards ISO 15874-1.2013 "hot and cold water equipment, plastic pipe system polypropylene Part 1. General Principles (English version). This section compared with ISO 15874-1.2013, the structure of the two appendices (normative Appendix A and informative Appendix B). This part of ISO 15874-1.2013 technical differences and the reasons are as follows. --- The scope of the standard is limited to the pipe and fittings to adapt to the domestic habits; --- The current effective national standards, instead of ISO 15874-1.2013 in the reference documents; --- Removed the definition of "nominal nominal size (nominalsize, DN/OD)" not adopted in China; --- Increased polypropylene pipe and pipe fittings with other ingredients of the table, in order to facilitate the production, research and quality supervision use. Please note that some of the contents of this document may involve patents. The issuing agencies of this document do not bear the responsibility of identifying these patents. This part is proposed by China National Light Industry Council. This part of the National Plastics Standardization Technical Committee (SAC/TC48) centralized. The main drafting of this section. China Petrochemical Co., Ltd. Beijing Yanshan Branch Institute of resin applications, Shanghai White Butterfly Industry Technology Co., Ltd., China Machine General Machinery Technology Co., Ltd., Icahn Enterprise Group (Shanghai) Co., Ltd., Jinde Management Group has Limited, Rifeng Enterprise Group Co., Ltd., Beijing Technology and Business University, Beijing North High-Tech New Technology Co., Ltd.. The main drafters of this section. Chen Hong Yuan, Chai Gang, Wu Wenli, Qiu Qiang, Wang Shiliang, Peng Xiaoyi, Xiang Aimin, Cheng Hongyuan. This part replaces the standards previously issued as. --- GB/T 18742.1-2002. Hot and cold water with polypropylene pipe system Part 1. General principles
