Need more than one copy? Excepting the Shore Durometer A, this test method requires no specialized, rubber-testing equipment. In this respect, this test method is useful for lubricant specifications for example, Specification D If the document is revised or amended, you will be notified by email.
Proceed to Checkout Continue Shopping. To address these limitations, testing standards have been established to evaluate compatibility.
In contrast to these two test methods, which emphasize the evaluation of rubber and rubber-like compounds, Test Method D was developed specifically to evaluate lubricating greases and fluids, especially those used in automotive applications, although the test method can be applied r4289 lubricants used in industrial applications as well.
Your Alert Profile lists the documents that asmt be monitored. These results are limited for a number of reasons. Testing of fluids was not included in Test Method D —95 and earlier versions.
ASTM D Standard Method of Testing Compatibility of Lubricating Grease with Elastomers
Testing of fluids was not included in Test Method D – 95 and earlier versions. Link to Active This link will always route to the current Active version of the asstm.
In contrast to these two test methods, which emphasize the evaluation of rubber and rubber-like compounds, Test Method D was developed specifically to evaluate lubricating greases and fluids, especially those used in automotive applications, although the test method can be applied to lubricants used in industrial applications as well.
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. And in many test recommendations, there are no established guidelines for static or dynamic applications.
Similarly, this test method can be used in specifications for lubricating fluids as well. Add to Alert PDF. In this respect, this test method is useful for lubricant specifications for example, Specification D Virtually all other equipment and supplies specified in the procedure are stock items in lubricants laboratories.
We have no amendments or corrections for this standard. The scope of this test method now includes the evaluation of the elastomer compatibility of both lubricating fluids and greases. What this approach fails to address are the interactions between an actual polymer material and the specific formula of a given fluid — including a host of additives and contaminants that often go unaccounted for but significantly alter the equation.
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.
Please first verify your email before subscribing to alerts. We have no document history for this standard. Such values may or may not be the same as those of Test Method D Because some fluids experience chemical changes at higher temperatures, specific temperatures were used to control this.
For specific warning statements, see 8. Note The scope of this test method now includes the evaluation of the elastomer compatibility of both lubricating fluids and greases.
Testing Parameters The base test parameters included volume swell, mass and density changes, hardness, tensile strength, elongation, percent modulus, work function area under tensile curve up to 20 percentcompression set and abrasion resistance. Developing New Test Methods To fully evaluate material-fluid compatibility, System Seals developed new methods from various standards, as well as experience from seals in broad applications.
Standard Test Method for Elastomer Compatibility of Lubricating Greases and Fluids
No other units of measurement are included in this standard. Subscription pricing is determined by: Even when exposure times are sufficiently long, the evaluations might be limited to measuring changes in only volume and s4289.
During the testing it became necessary to understand how the mechanical properties changed from exposure. It is recommended that the awtm upon precision values be stated in the user’s lubricant specification.
This standard is not included in any packages. Most test standards also do not incorporate changes in the transition temperature, which is critical for low-temperature applications. Ashm at the System Seals laboratory revealed that some fluid-material combinations that appear compatible at 1, hours later became incompatible after 2, hours. It is recommended that the agreed upon precision values be stated in the user’s lubricant specification.
This standard is also available to be included in 4d289 Subscriptions. 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. Still, there are considerable inconsistencies among these tests. Already Subscribed to this document.

Such values may or may not be the same as those of Test Method D You can download and open this file to your own computer but DRM prevents opening s4289 file on another computer, including a networked server. To ensure full saturation, the testing ran for 2, hours, or 12 weeks.
We have no amendments or corrections for this standard.
