This test method has been found useful for specification purposes, but does not necessarily measure the lowest temperature at which the material is suitable for use.

CCSi UltraLife specimen cutting dies are individually serialized, hand-honed, and mirror polished. Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. The test provides for the evaluation of long-time effects such as crystallization, or those effects that are introduced by low-temperature incompatibility of plasticizers in the material under test.

When testing plastic sheeting for impact brittleness, use Test Method D Aetm are secured in the customer specified specimen aatm A or B with a torque asmt at 5 in-lb. Link to Active This link will always route to the current Active version of the standard.

Auditing Consulting Sourcing Training. Inspection Validating the specifications, value and safety of your raw materials, products and assets. ASTM D employs three cutting dies: Standards can be obtained from appropriate standards authorities. The quality of materials, design, and engineering serve to provide the highest specimen quality possible, over an extended service life.

A asmt coating of industrial enamel is applied to the non-cutting surfaces before undergoing a rigorous final inspection. There are three specimens: Need help or have a question?

Active Risk Management

The procedure is repeated at a lower temperature until enough data is generated to determine a brittleness temperature. Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards.

It is utilized primarily for plastics and elastomers. This test provides for the evaluation of long term effects, such as crystallization, or the incompatibility of material borne plasticizers when subjected to subnormal temperatures.

Brittle failure is defined by ASTM D as fracture into 2 or more pieces, or any crack visible to the unaided eye.

Global Reach Intertek is the industry leader with over 42, people in 1, locations in over countries. When testing rubbers for impact brittleness use Test Method D Due to copyright restrictions, we are not able to provide copies of standards. Each undergoes multi-axis precision grinding and conventional, plunge, or wire EDM Electrical Discharge Machining processes Use data obtained by this method to predict the behavior of plastic and elastomeric materials at low temperatures only in applications in which the conditions of deformation are similar to those specified in this test method.

CCSi UltraLife specimen cutting dies are manufactured from homogenous, solid, high carbon content A2 tool steel.

The brittleness temperature is determined by immersing the specimens in the specimen holder in a bath containing a heat transfer that is cooled, usually by liquid nitrogen, carbon dioxide, or powdered dry ice, to a predetermined temperature for a period of three minutes. The results may be used to predict the behavior of plastic and elastomeric materials at low temperatures.

Certification Formally confirming that your products and services meet all trusted external and internal standards. The specimen holder is lowered into a bath at a specified temperature.

However, this holds only under conditions in which the material is subjected to deformations similar to those imposed in the test. 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.
