Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard replaces GB/T 15902-2009 "determination of elastic elongation and elongation of the conveyor belt and calculation of elastic modulus", Compared with GB/T 15902-2009, the main technical changes are as follows. --- The ISO 7500-1 Chinese name "static test of metallic materials uniaxial testing machine Part 1. Tensile/compression testing machine Testing and calibration of force measuring system "is corrected to" Inspection of metallic materials, static uniaxial testing machine Part 1. Rally and (Or) pressure testing machine testing system and calibration "(see Chapter 2,.2009 Edition Chapter 2); --- Modify the normative references (see Chapter 2,.2009 edition Chapter 2); --- Modify the definition of high reference force and unit (see 3.3,.2009 edition 3.3); --- Modify the definition of low reference force and unit (see 3.4,.2009 version 3.4); --- Modify the definition of specific force range parameters (see 3.5,.2009 version 3.5); --- Modify the principle (see Chapter 4,.2009 edition Chapter 4); --- Modify the figure Y in Figure 1 units (see Figure 1,.2009 edition of Figure 1); --- Increasing the formula number (see Chapter 10,.2009 edition Chapter 10). This standard uses the translation method identical with ISO 9856.2003 "Determination of conveyor belt elastic elongation and permanent elongation and elastic modulus Calculation of Amount (English version). The documents of our country that are consistent with the corresponding international documents that are normative references in this standard are as follows. --- GB/T 3690-2017 fabric core conveyor full thickness tensile strength, elongation at break and reference force elongation test side Act (ISO 283.2015, IDT) --- GB/T 16825.1-2008 static uniaxial testing machine test Part 1. Rally and (or) pressure testing machine force measuring system Inspection and calibration of systems (ISO 7500-1.2004, IDT) --- GB/T 30691-2014 conveyor belt test environment and state conditioning time (ISO 18573.2012, IDT) --- HG/T 2410-2006 conveyor belt sampling (ISO 282.1992, IDT) This standard also made the following editorial changes. --- Incorporation of ISO 9856.2003 Amendment No. 1 (ISO 9856.2003/Amd.1.2012), while the modified terms The outer margins are marked with vertical double lines (‖). --- Remove the note in 3.9 and 3.10. This standard proposed by the China Petroleum and Chemical Industry Federation. This standard by the National Belt and Belt Standardization Technical Committee Conveyor Belt Technical Committee (SAC/TC428/SC1) centralized. This standard was drafted unit. Qingdao Shinkansen Technical Consulting Co., Ltd., South Africa Rubber Group Co., Ltd., Qingdao University of Science and Technology. The main drafters of this standard. Lv Guiqin, Wang Chuanui, Xin Yong recorded. This standard replaces the standards previously issued as. --- GB/T 15902-1995, GB/T 15902-2009. Conveyor belt elastic elongation and permanent elongation Determination and calculation of elastic modulus
