Through our network of over 43, people in 1, laboratories and offices in countries, Intertek provides quality and safety solutions to a wide range of industries around dd6641 world. Work Item s – proposed revisions of this standard. Historical Version s – view previous versions of standard. Due to the very large number of tests offered, descriptions of those most commonly requested have been gathered into the following groups:.

Factors that c6641 the compressive response include: The test fixture is designed to provide a combined loading to the unsupported center 12 mm 0. A gage length between 12 mm and 25 mm [1. One requirement for a successful test is that the specimen ends do not crush during the test. Within the test the inch-pound units are shown in brackets.

Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. The test specimen is inserted into the two halves of the test fixture so that the ends of the specimen are flush with the top and bottom of the test fixture, and the bolts in the fixture are tightened to a specified torque to capture the test specimen.

This test method determines compressive properties of polymer composite materials by applying combined end-loading and shear-loading using a combined loading compression CLC fixture.

Have a question about conducting the test for this standard? Formally confirming that your products and services meet all trusted external and internal standards. Materials of higher orthotropy, including unidirectional composites, typically require tabs. The specimen may be untabbed Procedure A or tabbed Procedure Bas required. Please email info trl. It may not be possible to successfully test untabbed specimens of these same materials using either of the other two methods.

Active view current version of standard. The specimen may be untabbed Procedure A or tabbed Procedure Bas required. Composite properties in the test direction that may be obtained from this test method include:. Need help or have a question?

One of the basic rules is that the ends of the specimen does not crush during the test. Specimens may be tabbed or untabbed depending on the specimen material and specimen failure during v6641 testing.

This test method is applicable to general composites that are balanced and symmetric. Select from list below: 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. When testing lower strength materials such that untabbed CLC specimens can be used Procedure Athe benefits of combined loading become particularly prominent.

Composite properties in the test direction that may be obtained from this test method include: When a material has a high compressive strength in the direction of loading, end crushing may occur. This test method determines compressive properties of polymer composite materials by applying combined end-loading and shear-loading using asym combined loading compression CLC fixture. 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.

Compressive Properties (CLC) by ASTM D

One requirement for a successful test is that the specimen ends do not crush during the test. The fixture is placed between the platens of a Universal Testing Machine, and if a strain measuring device is being used, it is attached to the specimen.

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. The compressive force is introduced d6641 the specimen by combined end- and shear-loading. Assurance Testing Inspection Certification.
