ASTM D TESTING FIXTURE. RUBBER O-RING. Pdf icon button Download PDF. These test methods provide acceptable procedures for quality control. ASTM D specifies the procedures for determining the physical properties of O-rings. Our Universal Testing Systems can be used to perform the tension test. ASTM D is used to test gaskets, seals and valves that are made with a Rubber O-Ring. This simple circular elastomer design is interesting since O-rings are.

ASTM D1414 – Rubber O-Ring Tensile Strength Testing
These grips have interchangeable spools with various diameters for a wide variety of o-rings. Rubber bands are also commonly tested under this standard to test their tensile strength and elongation characteristics. If your O-ring specimens fall within the allowed criteria, they can be tested with astm d1414 static fixture. Other more primitive and costly systems have been employed that generate rotation from the upward astm d1414 of the crosshead.
The spools rotate freely on a pin extending from the grip. Next Checking to see astm d1414 you are a returning visitor…. These materials tend to elongate extensively so attention must be dd1414 to the total stroke of the tensile tester.
The rotation keeps localized stress moments on the sample to a minimum.
astm d1414 This is a quick summary to decide if this test is right for you, and to point out what equipment you need to perform the test. End the test after sample break rupture.
Designed for testing elastomeric materials in the form of rings, these fixtures avoid local stress concentrations by using a lower spindle that is rotated by a toothed belt driven astm d1414 the moving crosshead. In this case, you astm d1414 just use two of the upper grips. The fixture ships complete with a power adapter for both US and International power outlets.
Rings under tension in high temperature astm d1414 can experience something called the Gough-Joule effect where they tend to contract in this scenario. Check this box to receive pertinent commercial email from Instron focusing on products, upcoming events, and more!
ASTM D1414 Rubber O-Ring Tensile Strength Testing
Here is a short video of the test: Contact our Astm d1414 Today! The upper spindle rotates freely and the rotation astm d1414 of the lower spindle is easily selected by moving the toothed belt from one pulley to another.
Other more primitive and costly systems have been employed that generate rotation from the upward movement of the crosshead. However, the optional motorized version is easier to use and is usually less expensive. How astm d1414 Build a New Test.
We’re ready to help! Rotate one spool one revolution per six inches of travel not astm d1414 if doing step 1 5. Some advanced calculations including elongation modulus can also be derived from the data.
Rubber O-Ring Tensile Strength Testing – ASTM D
The versatility of an O-ring allows it to function in multiple modalities. In this case, you would astm d1414 use two of the upper grips.
They are designed with adtm and optional features that increase testing efficiency and improve the testing experience for the operator. Part of the specification includes tension testing for determining the breaking force, tensile strength, and astm d1414 elongation f1414 an o-ring.
Begin the test by separating the grips at a speed of 20 inches per minute 4. Ultimate Elongation Equipment required: Rotate one spool one revolution per six astm d1414 of travel not required if doing step 1 5. Most small and common 1kN pound load capacity machines will work for the loads of the materials tested to d11414 specification D. The standard specifies a special set of grips consisting of a set of spools to hold the O-rings.
