Determination of compression stress-strain properties ICS 83.060 G40 National Standards of People's Republic of China GB/T 7757-2009/ISO 7743.2007 Replacing GB/T 7757-1993 Vulcanized or thermoplastic rubber Determination of compression stress-strain properties (ISO 7743.2007, IDT) Posted 2009-04-24 2009-12-01 implementation Administration of Quality Supervision, Inspection and Quarantine of People's Republic of China Standardization Administration of China released ForewordThis standard is equivalent to using ISO 7743.2007 (E) "vulcanized rubber or thermoplastic rubber --- compression stress strain properties" English Text version. This standard replaces GB/T 7757-1993 "Rubber, vulcanized or thermoplastic - Determination of compression stress-strain properties." This standard is equivalent translation ISO 7743.2007 (E). For ease of use, this standard also made the following editorial changes. a) "this International Standard" be replaced by "this standard"; b) use a decimal point instead of a decimal comma ",". ","; c) Remove the International Standards Preface; d) remove the reference. This standard compared with the previous version, the main changes are as follows. --- Increased for the product of Test Method C (1993 Edition Chapter 1, Chapter 1 of this edition). --- Increased the provision of the sample (1993 Edition Chapter 1, Chapter 5, Chapter 6 Chapter 1 edition). --- Increased demands on the test machine (1993 version 4.4, this version 5.4). --- Increasing the normative Appendix B calibration (Excerpts Appendix B). Appendix A of this standard is an informative annex, Annex B normative appendix. The standard proposed by China Petroleum and Chemical Industry Association. This standard by the National Standardization Technical Committee and rubber products and chemical physics at the Technical Committee rubber rubber. This standard Central Rubber Group in Shenyang Rubber Research and Design Institute is responsible for drafting. The main drafters of this standard. Fecamp red. This standard replaces the standards previously issued as follows. --- GB/T 7757-1987, GB/T 7757-1993. GB/T 7757-2009/ISO 7743.2007 Vulcanized or thermoplastic rubber Determination of compression stress-strain properties Warning. Use of this standard should be familiar with normal laboratory practice. This standard does not purport relates to the use of this standard may occur All security issues. Develop appropriate safety and health system and to ensure compliance with national regulations is the responsibility of the user. Note. Some programs in this standard may result in waste and pollution to the local environment. After the safe use of the substance Manage these wastes, reference to the relevant literature.1 ScopeThis standard specifies the use of a standard sample, or a number of products - Determination of vulcanized rubber or thermoplastic rubber measured compressive stress-strain properties Setting Method. This standard specifies three methods. --- Using standard samples and the metal plate (Method A) by the lubricant lubrication; --- Using standard samples and the sample and the metal plate are bonded together (Method B); --- Use part of the product or products and the metal plate by Lubricate (Method C). The results of three methods are not the same. For lubricated by the sample, if it reaches sufficient lubrication, the test results only to rubber mold For the amount, regardless of the shape of the specimen. However, effective lubrication is often difficult to achieve, it should be the same test sample, the difference comparative test results To represent different lubrication conditions. For samples with a metal plate bonded together, the modulus of the rubber and the test results of the sample shape. Sample shape a greater impact on the test results, therefore, the test results and the results by Lubricate the specimen obtained is not significant with. For the product, depending on the results of the test specimen geometry, but the product is mainly used in the test for comparison purposes, it is acceptable. Note. For clearly defined shape of the product, such as О-rings, the test results may be associated with hardness values. However, with respect to a predetermined size and shape of the different samples Thus, the obtained results can not be extrapolated to other sizes and shapes of the test. Appendix A gives the size and shape of the adhesive or lubricant guidelines impact on the results of the sample. This method is not permanent deformation of the material used. Appendix B gives a list of this type of calibration measurements.2 Normative referencesThe following documents contain provisions which, through reference in this standard and become the standard terms.
