Rubber, vulcanized or thermoplastic - Determination of compression stress-strain properties (ISO 7743:2004) English version of DIN ISO 7743:2006-11

DIN ISO 7743-2006 发布历史

This International Standard specifies methods for the determination of the compression stress-strain properties of vulcanized or thermoplastic rubber, using a standard test piece, a product or a part of a product. Three procedures are given: — using a standard test piece with the metal plates lubricated (method A); — using a standard test piece with the metal plates bonded to the test piece (method B); — using a product or a part of a product with the metal plates lubricated (method C). The three procedures do not give the same results. With lubricated test pieces, the results are dependent only on the modulus of the rubber and are independent of the test piece shape, provided that complete slip conditions are achieved. Effective lubrication is sometimes difficult to achieve, however, and it is prudent to inspect the variance in the test results from replicate test pieces for indications of erratic slip conditions. With bonded test pieces, the results are dependent on both. the modulus of the rubber and the test piece shape. The dependence on test piece shape is strong and consequently the results will be markedly different from those obtained with lubricated test pieces. For products, the result is dependent on the shape, but as tests on products are mainly comparative this is acceptable. NOTE For well-specified product shapes, such as 0-rings, the result may be correlated to the hardness value. Provision is made for the use of test pieces of different size and/or shape from the specified test piece, but extrapolation of the results obtained to other sizes and shapes may not be possible. Guidance on the effect of size and shape of test piece and of bonding or lubricating is given in Annex A. The method is not suitable for materials that exhibit high set. The necessary calibration schedule for this type of measurement is included in Annex B.
