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 d44289 for use in preparing coupons for testing Practice Dthis test method can be used as a guide for evaluating compatibility.

For specific warning statements, see 8. Limited exposure times and a lack of application-based testing have created shortfalls that have paved the way for industry-wide acceptance of generalizations about entire material families that mistakenly group different materials into single categories, the research found.

The duration times dedicated to the tests are not standardized, nor are they often specified. 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 e4289 fluids, especially those used in automotive applications, although the test method can be applied to lubricants used in industrial applications as well.

Industry Standard Tests Theoretical models that have been established to predict fluid compatibility are based largely on the laws of chemistry.

ASTM D4289 – 13(2014)e1

As the voice of the U. As the voice of the U. We have no amendments or corrections for this standard. Approximately 25 percent of the material-fluid combinations that successfully passed at the day mark, soon began to fail near or after 60 days. 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.

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 awtm indicative of the true compatibility characteristics.

Add to Alert PDF. To ensure full saturation, the testing ran for 2, hours, or 12 weeks. These results are limited for a number of reasons. Testing ast, fluids was not included in Test Method D —95 and earlier versions. Subscription pricing is determined by: We have no amendments or corrections for this standard.

This standard is not included in any packages. Some of the tests were performed by customer request, while others were conducted to round out the research and record for future use. When the preparation of such coupons is not feasible, or asm 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.

Excepting the Shore Durometer A, this test method requires no specialized, rubber-testing equipment. The asttm testing consisted of three main components: Testing of fluids was not included in Test Method D —95 and earlier versions.

The scope of this test method now includes the evaluation of the asgm compatibility of both lubricating fluids and greases. Need more than one copy? Virtually all other equipment and supplies specified in the procedure are stock items in lubricants laboratories. For the past several years, System Seals, a research-based seal manufacturer in Cleveland, has undertaken an exhaustive fluid compatibility study that paired more than combinations of seal materials with commonly used industrial fluids.

Friction, wear and motion can contribute to additional failure risks. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Link to Active This link will always route to the current Active version of the standard. 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.

In the System Seals trials, dd4289 of the materials underwent additional testing, included breaking points, tensile strength, elongation, volume swell, abrasion resistance and hardness — all qualities required for safe seal performance and longevity. Already Subscribed to this document. Two HNBRs, for instance, might demonstrate different property changes depending on the levels of fillers and additives.

However, they can be correlated in many instances. Volume swell is a good indicator of fluid absorption, which is important because many seal grooves have between percent free space available. When volume increases are limited to 15 percent, contraction can be no more than 5 percent.

Engineering Applications The ultimate purpose of a chemical compatibility ast, is to evaluate the ability of an elastomer to function as a seal in its intended application when exposed to a working fluid. To address these limitations, testing standards have been established to evaluate compatibility. No other units of measurement are included in this standard.

We have no document history for this standard. Fluid incompatibility is one of the leading causes of ashm failure, so when a multi-million-dollar operation becomes dependent on the performance of a group of seals, it is critical that the testing is sufficient, accurate and complete, and that the operator has confidence that the seal system will perform to its greatest ability.

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

Excepting the Shore Durometer A, this test method requires no specialized, rubber-testing equipment. 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.

Several of the fluid-material combinations that passed successfully within 28 days failed after longer exposures. You may delete a document from your Alert Profile at any time.

Historical Version s – view previous versions of standard. In this respect, this test method is useful for lubricant specifications for example, Specification D 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.

During the testing it became necessary to understand how the mechanical properties changed from exposure.
