No other units of measurement are included in this standard. This standard is not included in any packages. Contraction, however, is more problematic because loss of seal volume reduces seal force. Fluid and seal manufacturers routinely perform their own tests, which usually result in compatibility ratings in broad generalizations for entire families of elastomers.

For specific warning statements, see 8. ASTM D, for instance, typically incorporates tests with a maximum exposure time of 70 hours, which significantly limits long-term predictive capabilities. Because some fluids experience chemical changes at higher temperatures, specific temperatures were used to control this. We have no amendments or corrections for this standard. No other units of measurement are included in this standard.

The duration times dedicated to the tests are not standardized, nor are they often specified. In critical applications where the lubricant will be in contact with rubber parts subject to severe flexing, extreme temperatures, or similar stresses, other rubber properties, such as tensile strength and elongation, should also be evaluated as they may be more indicative of the true compatibility characteristics.


Still, there are considerable inconsistencies among these tests.

Standards Subsctiption may be the perfect solution. No other units of measurement are included in this standard.

ASTM D – 03 Standard Test Method for Elastomer Compatibility of Lubricating Greases and Fluids

Your Alert Profile lists the documents that will be monitored. When the preparation of such coupons is not feasible, or the lubricant specification requires the use of rubber products that do not have a suitable size or configuration for use in preparing coupons for testing Practice Dthis test method can be used as a guide for evaluating compatibility.

The company ran chemical compatibility simulations between 60 to 90 days, and in some cases longer. This standard is not included in any packages. Add to Alert PDF. Subscription pricing is determined by: An increase in mass might also indicate fluid absorption, and a loss in mass usually indicates chemical degradation. Testing of fluids was ashm included in Test Method D – 95 and earlier versions.

Excepting the Shore Durometer A, this test method requires no specialized, rubber-testing equipment. As the voice of the U. For specific warning statements, see 8. If the document is revised or amended, you will be notified by email. Testing of fluids was not included in Test Method D —95 and earlier versions. Even when exposure times are sufficiently long, the evaluations might be limited to measuring changes in only volume and hardness.


It is recommended that the agreed upon precision values be stated in the user’s lubricant specification. When volume increases are limited to 15 percent, contraction can be no more than 5 percent. Asfm the testing it became necessary to understand how the mechanical properties changed from exposure.

Even in a thorough compatibility program, performance asrm only be inferred. The times vary considerably among manufactures, usually ranging from a week to 30 days. Similarly, this test method can be used in specifications for lubricating fluids as well. In such instances, the repeatability and reproducibility values stated in Section 12 do not apply, and the user and supplier should agree on acceptable limits of precision.

And, it is impossible to accurately deduce material changes for one material based on the results of another, even if the materials are in asym same family. This standard is also available to be included in Standards Subscriptions.
