Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard replaces GB/T 6111-2003 "Test method for internal pressure resistance of thermoplastic pipes for fluid transfer" and GB/T 6111- Compared with.2003, the main technical changes are as follows. --- The scope has been expanded from "pipe" to "pipe, components and assemblies" (see Chapter 1); --- Added the following terms. component (3.1), standard size ratio (3.2), free length (3.3); --- The average temperature of the oven, modified from 3-1 °C to 2-1 °C (6.2); --- Added "size measuring device" requirement (6.8), deleted "thickness gauge" and "pipe average outer diameter ruler"; --- Increased and modified sample types and related requirements (see Chapter 7); --- Increased the calculation method of test pressure. According to the nominal size of the sample and the pressure calculation method according to SDR (8.3, 8.4); --- Increased the "test has been carried out for 500h ~ 1000h" when the treatment method (11.3); ---In the test report, "f) "Sample preparation conditions" and "l) Condition adjustment time" are added (see Chapter 12); --- Deleted the original standard data Appendix A; --- Increased the normative appendix A, appendix B, appendix C, respectively, the pipe, assembly, assembly sample preparation requirements. This standard uses redrafted reference ISO 1167-1.2006 "Thermoplastic Pipes, Components and Assemblies for Fluid Conveyance Determination of Pressure Properties - Part 1. General Test Methods, ISO 1167-2.2006, Thermoplastic Pipes, Components and Combinations for Fluid Delivery Determination of internal pressure resistance of parts - Part 2.

Introduction

This standard will be ISO 1167-1.2006 "Determination of internal pressure resistance of thermoplastic pipes, components and assemblies for fluid transport. Part 1. General test methods, ISO 1167-2.2006, "Insulation resistance of thermoplastic pipes, components and assemblies for fluid transport Determination of Part 2. Preparation of Pipe Specimen, ISO 1167-3.2007, Thermoplastic Pipes, Components and Assemblies for Fluid Delivery Determination of internal pressure properties - Part 3. Preparation of component specimens", ISO 1167-4.2007, Thermoplastics pipes, components for fluid transport, and Measurement of the inner pressure resistance of the assembly Part 4. Preparation of the assembly test piece. The four parts were combined into one text, redrafted, packaged Including editorial changes, the main technical differences between this standard and ISO 1167 are as follows. --- Consolidation of the four parts of ISO 1167 into one text, technical content of ISO 1167-2, ISO 1167-3, ISO 1167-4 Do not use this standard normative appendix A, appendix B, appendix C; --- Normative references have been replaced or increased or decreased using domestically relevant similar standards; In the text, where there are national standards that correspond to international standards, national standards are used instead of directly adopting international standards; --- Increased the normative reference document GB/T 19278-2003; --- Uniformly modify the pressure unit involved in the standard to China's statutory unit MPa "MPa"; --- Modify Figure 1, and mark the free length in the figure; --- The formulas were numbered to comply with the relevant provisions for the drafting of China's national standards; --- Added "Type A type sealing joint when performing arbitration test"; --- Added "pipe arbitration test using measuring dimensions to calculate test pressure"; --- Modify the "minimum state adjustment time" requirement to "state adjustment time" and give the deviation. Thermoplastic pipe system for fluid delivery Resistance to internal pressure

1 Scope

This standard specifies tests for determining the resistance to internal pressure of thermoplastic pipes, components and assemblies for fluid delivery at a given temperature. method. This standard applies to water inside the sample, external water (water - water test), air (water - air test) and other liquids (water - other liquids Test) internal pressure resistance test.
