Basic dataStandard ID: GB/T 1688-2008 (GB/T1688-2008)Description (Translated English): Rubber, vulcanized -- Determination of tension fatigue Sector / Industry: National Standard (Recommended) Classification of Chinese Standard: G40 Classification of International Standard: 83.060 Word Count Estimation: 16,121 Date of Issue: 2008-06-04 Date of Implementation: 2008-12-01 Older Standard (superseded by this standard): GB/T 1688-1986 Quoted Standard: GB/T 2941 Adopted Standard: ISO 6943-2007, IDT Issuing agency(ies): General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China, Standardization Administration of the People's Republic of China Summary: This standard specifies the method for measuring the tensile deformation under repeated fatigue resistance in vulcanized rubber. In the sample size and the cycle frequency basically unchanged or no temperature conditions leading to crack growth defects, and finally to the specimen fracture. This method is suitable for the stress-strain properties of rubber stable, at least in a certain period after the loop, did not exhibit undue stress softening or permanent deformation, or high viscous state. GB/T 1688-2008: Rubber, vulcanized -- Determination of tension fatigue---This is a DRAFT version for illustration, not a final translation. Full copy of true-PDF in English version (including equations, symbols, images, flow-chart, tables, and figures etc.) will be manually/carefully translated upon your order.Rubber, vulcanized. Determination of tension fatigue ICS 83.060 G40 National Standards of People's Republic of China GB/T 1688-2008/ISO 6943.2007 Replacing GB/T 1688-1986 Determination of fatigue vulcanized rubber stretch (ISO 6943.2007, IDT) Posted 2008-06-04 2008-12-01 implementation Administration of Quality Supervision, Inspection and Quarantine of People's Republic of China Standardization Administration of China released ForewordThis standard is identical with ISO 6943.2007 "Determination of vulcanized rubber stretching fatigue" (in English). This standard replaces GB/T 1688-1986 "Rubber, vulcanized - Determination of tension fatigue." This standard is equivalent translation ISO 6943.2007 (in English). For ease of use, this standard made the following editorial changes. a) "this International Standard" by "this standard"; b) Remove the foreword to international standards; c) use the decimal point. "" instead of a comma as the decimal symbol "." This standard compared with GB/T 1688-1986, the main changes are as follows. --- Increased warnings; --- Increasing the normative references (Chapter 2 of this edition); --- Increased cyclic sample (this version 6.1.3); Permanent deformation and fatigue increase the maximum strain --- after measurement (edition 8.5); --- Increases the maximum stress and maximum strain energy density measurement (edition 8.6); --- Increased permanent deformation calculation (edition 9.2); --- Increasing the calculation of the maximum strain (edition 9.3); --- Increased calculate the maximum stress (edition 9.4); The fatigue test and GB/T 15584 flexing tests described are different, which is both the fatigue fracture stress and temperature for By the following occurred. This test is superior de Mexico subtype flex cracking and cut growth test (see GB/T 13934), its advantage can be obtained automatically Quantitative results recorded, independent operator of analysis and interpretation; can accurately determine the initial deformation, and easily changed to suit different purposes. When using a standard test results for the practical application of the correlation analysis, it requires special attention, because of the different vulcanized rubber anti-fatigue Lo test results are different, the test conditions and compare the content and methods used in the test results related. Appendix A gives a selection test Test conditions and the interpretation of test results described.2 Normative referencesThe following documents contain provisions which, through reference in this standard and become the standard terms. For dated references, subsequently Some amendments (not including errata content) or revisions do not apply to this standard, however, encourage the parties to the agreement are based on research Study whether the latest versions of these documents. For undated reference documents, the latest versions apply to this standard. GB/T 2941 rubber physical test method for preparing and conditioning General Procedure (GB/T 2941-2006, ISO 23529.2004, IDT)3 Terms and DefinitionsThe following terms and definitions apply to this standard. 3.1 Under the provisions of the tensile strain, the specimen deformation repeatedly until the desired fracture cycles.
