Elastocon offer the following:. September 28th, by Nathan Enser.
This service is not available if you are a URL user where you do not log in with an email address. The Gehman test is used to determine the relative stiffness of a material over a wide temperature range. You need to log in before adding standards to d21377 monitoring service.
Brittleness Tester, ET 05-II
Need more than one copy? The system also includes the software d a computer astm d the first year support agreement. We can also offer calibration and polymer testing on commission.
When seal materials reach low-temperature limits, they will harden and resist deformation to pressure, causing leak paths. Low-temperature nitrile Analyzing the Data Although this test helps determine which materials can take higher stress at low d137, it certainly comes with some drawbacks.
Astm d this test is the equivalent of hitting astm d material with a hammer, the test can be passed at lower temperatures by increasing the strength of the material to be tested. Already Subscribed to this document. Elastocon’s own instruments are sold worldwide. Testing of Uncured Rubber. More information for Elastocon solutions for low temperature testing can be found here.
These test methods cover the xstm of rubber materials or fabrics coated therewith subjected to low-temperature flex with an impact under well-defined conditions of astm d speed. Start Webshop Product catalog Product presentation. To determine this, a different test would be necessary to show that loss of flexibility.
Since there is no universal test that will provide all of the necessary information, engineers must perform the right tests for a given situation.
Combined Low Temperature Tester from Elastocon. The response is largely dependent astm d effects of low temperatures such as crystallization, incompatibility of plasticizer, astm d the inherent dynamic behavior of the material itself.
Brittleness Tester, ET II – Elastocon AB
This test measures the ability of a material to withstand breaking when bent at a given temperature for a specific period of time. The seal will also undergo a compression set, which means it will leak when heated back above the low temperature.
To evaluate cold temperature properties in rubber parts and seals, engineers perform several different test standards. The moment new editions of the standards you monitor are released, changes are made, or appendixes are published, you will be axtm by email. Low temperatures raise big concerns for rubber manufacturers. The results can be illustrated in a graph as the relative modulus against temperature between the stiffness at each temperature and room temperature, as shown in Figure 8.
Applications in major industries like automotive, railroad and industrial processing demand peak seal performance in cold, harsh environments.
