Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Record the force at the elongation specified for the test and at the time of rupture. Method A can be performed using a universal testing machine capable of constant rate of extension CRE control. Have a question about conducting the test for this standard? Tensile set is expressed in percent and is calculated by dividing the change in length of the test sample by the initial length.
Start the test machine and astm d412 the force and corresponding distance between the astm d412. ASTM D covers two test methods: ASTM D specifies a dumbbell shaped specimen. Formally confirming that your products and services meet all trusted external and internal standards.
ASTM D TESTING FIXTURE
astm d412 Method B is a less common test, requiring rubber ring samples. Works very well with flat, thin specimens Eccentric design increases gripping force with tension. The initial length between these marks is measured for each sample.
It is the responsibility of the user of this standard to establish appropriate safety and health practices and asgm the applicability astm d412 regulatory limitations prior to use. Testing Evaluating how your products and services meet and exceed quality, safety, zstm and performance standards.
ASTM D412 TESTING FIXTURE
Link to Active This link will always route to the current Active version of the standard. Load ratings from 1 kN to 10 kN lbf to 2, lbf Maximum specimen thicknesses of 7 mm or 8 mm 0. Whether your business is local or global, we can ensure your products meet quality, health, environmental, safety, and social accountability standards for virtually any market around the world.

Need help or have a question? By means of our extensive testing expertise and modular product design, we will help configure the testing solution that is right for you. ASTM D gives you the choice of six specimen geometries and cutting die. Two marks are precisely placed on each test sample at the ends of the gauge length of the dumbbell shaped specimens. To determine tensile set, place the specimen in the grips and adjust symmetrically.
These two different astm d412 do not produce identical results. Cuts astm d412 specimens from stock material Available for a wide variety of ISO and ASTM standards Consistent specimens for consistent results Manufactured with tool steel to resist damage and wear over time.
Method A is a common guideline for evaluating the tension properties of dumbbell samples of vulcanized thermoset rubbers and thermoplastic elastomers. Measure the distance between the bench marks.
The methods appear as follows:. Assurance Testing Inspection Certification.
When the specimen breaks, measure and record the ultimate breaking elongation and the tensile force strength. These ast, are not applicable to ebonite and similar hard, low elongation materials. G Series Pneumatic Grip. Die C has an astm d412 length of mm 4. This provides a gauge length benchmark 25mm 1 inch long and a gauge width of 6mm 0. Asym the specimen breaks, measure and record the elongation. Method B covers procedures to evaluate the tension properties of flat ring samples of vulcanized thermoset rubbers and thermoplastic elastomers.
