Foreword

GB/T 5836 is divided into 2 parts.

---GB/T 5836.2-2018 Unplasticized polyvinyl chloride (PVC-U) pipe fittings for building drainage.

This part is Part 1 of GB/T 5836.

This section was drafted in accordance with the rules given in GB/T 1.1-2009.

This part replaces GB/T 5836.1-2006 "Unplasticized Polyvinyl Chloride (PVC-U) Pipes for Building Drainage", and GB/T 5836.1-2006 in comparison, the main technical changes are as follows.

---Added terms and definitions (see Chapter 3);

---Modified the material requirements and added the requirements for resin K value (see 4.2);

---Added the classification of pipes. According to whether the additives contain lead, they are divided into lead-free pipes and lead-containing pipes (see 5.2);

--- Corrected the nominal wall thickness of dn315 (see 6.3.1);

--- Increase the elongation at break requirements (see Table 4);

--- Deleted the requirements for the methylene chloride immersion test;

--- Increase lead limit requirements (see 6.6);

---Modified the pipe drop hammer impact test conditions (see 7.9);

---The factory inspection items have increased the density requirements (see 8.3.1);

---The size group of pipes has been added (see 8.4.1);

---Modified the sampling plan to increase the acceptance quality limit (AQL) from 6.5 to 4.0 (see 8.4.2);

---Increased the performance of the mixed materials used for PVC-U pipes (see Appendix A).

1 Scope

This part of GB/T 5836 specifies the terms and definitions of unplasticized polyvinyl chloride (PVC-U) pipes (hereinafter referred to as "pipes") for building drainage Definitions, materials, product classification, requirements, test methods, inspection rules, markings, transportation and storage.

This section applies to pipes for drainage systems in buildings that use polyvinyl chloride (PVC) resin as the main raw material and are extruded. On the test Considering the chemical resistance and heat resistance of the material, it can also be used for industrial drainage pipes.

The pipes specified in this section are used in conjunction with the pipe fittings specified in GB/T 5836.2-2018.
