Foreword
This 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 references
The 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.
