Through our network of over 43, people in 1, laboratories and offices in countries, Intertek provides quality and safety solutions f5379 a wide range of industries around the world.

A notched beam specimen is placed in a shear fixture.

Inspection Validating the specifications, value and safety of xstm raw materials, products and assets. Touchstone Research Laboratory, Ltd. ASTM D Either in-plane or interlaminar shear properties may be evaluated using ASTM D depending upon the orientation of the material coordinate system relative to the loading axis. The materials are either continuous-fiber or discontinuous-fiber-reinforced composites. Historical Version s – view previous versions of standard. Standards can be obtained from appropriate standards authorities.

Only a single shear plane may be evaluated for any given specimen. Formally confirming that your products and services meet all trusted external and internal standards.


The upper fixture should contain a linear bearing dd5379 mounts over the shaft on the base. 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. Assurance Testing Inspection Certification. Assurance Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes.

A special fixture is used to hold the coupon and load is applied at a specified rate until failure occurs. This test procedure introduces the compressive force into the specimen through shear at grip interfaces. Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards.

Global Reach Intertek is the industry leader with over 43, people in 1, locations in satm countries.


Properties determined from this test may be used for material specifications, research and development, quality assurance and structural design and analysis.

Make sure that the specimen is centered in the fixture and that it is contacting both upper and lower grip jaws on both sides r5379 still being supported on the back side. Lightly tighten the left-hand-side-jaw, and then lightly tighten the right-hand-side jaw.

Place the specimen loosely into the fixture making sure the notch alignment tool is pulled up into the notch. When the specimen breaks, record the maximum force, the force at failure and the strain as near as possible to the failure.
