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 the world.

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 ashm specimen. It is the responsibility of the user of atsm standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

The compressive force is introduced into the specimen by combined end- and shear-loading. When a material has ashm high compressive strength in the direction of loading, end crushing may occur. Assurance Testing Inspection Certification. Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. Within the test the inch-pound units are shown in brackets.

One requirement for a successful test is that the specimen ends do not crush during the test. This test method is designed to produce compressive property data aetm material specifications, research and development, quality assurance, s6641 structural design and analysis. Within the test the inch-pound units are shown in sstm. 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.

Active view current version of standard. When testing lower strength materials such that untabbed CLC specimens can be used Procedure Athe benefits of combined loading become particularly prominent. Failure to carefully prep your sample can result in premature end-crushing of the specimen during loading, excessive induced bending or buckling, and even invalidation of your test.

Compressive Properties (CLC) by ASTM D

Work Item s – proposed revisions of this standard. 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.

Touchstone Research Laboratory, Ltd. For high orthotropic materials, such as unidirectional composites, tabs are requested.

ASTM D6641

If the fixture clamping forces do induce significant stress concentrations at the ends of the gage section, tabbing is required for the material in order to increase the load-bearing area at the specimen ends. Combining values from the two systems may result in nonconformance with the standard.

Many factors can influence the compressive response during the test, including type of material, methods of material preparation and lay-up, specimen stacking sequence, specimen conditioning, specimen preparation, speed of testing, environment of testing, time at temperature, void content, and volume percent reinforcement.

Compressive Properties (CLC) by ASTM D6641

One requirement for a successful test is that the specimen ends do not f6641 during the test. Due to the very large number of tests offered, descriptions of those most commonly requested have been gathered into zstm following groups: The test fixture is designed to provide a combined loading to the unsupported center 12 mm 0.

Force range of 5 kN to kN 1, lbf tolbf Adjustable test space The most popular choice for static tension and compression tests These dual column testers are available in both tabletop and floor standing models.

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. Specimens should have a uniform rectangular ast, section, 12 mm 0.

Certification Formally confirming that your products and services meet all trusted external and internal standards. Standard load ratings up to kN 67, lbf ; higher ratings available upon request Platen diameters from 56 mm to mm 2. Give one of our application engineers a call today for help with creating the best budget and testing plan according to ASTM D 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.
