ASTM D395-03(2008) Method BStandard Test Methods for Rubber Property—Compression Set

ASTM D395-03(2008)橡胶特性的标准试验方法 — — 压缩设置

样品要求：

“A型试片: 29 mmDIA×12.5mm(可不超过3层叠加) 或

B型试片:13 mmDIA×6mm (可不超过3层叠加)

3 pcs(备注: ASTM D395中A型试样叠层不得超过7层, B型试样叠层不得超过4层)

周期：7~9个工作日

Scope：

1.1These test methods cover the testing of rubber intended for use in applications in which the rubber will be subjected to compressive stresses in air or liquid media. They are applicable particularly to the rubber used in machinery mountings, vibration dampers, and seals. Two test methods are covered as follows:

Test Method                                                                        Section

A-Compression Set Under Constant Force in Air                  7-10

B-Compression Set Under Constant Deflection in Air            11-14

1.2 The choice of test method is optional, but consideration should be given to the nature of the service for which correlation of test results may be sought. Unless otherwise stated in a detailed specification, Test Method B shall be used.

1.3 Test Method B is not suitable for vulcanizates harder than 90 IRHD.

1.4 The values stated in SI units are to be regarded as the standard.

1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
