The specimen holder is lowered into a bath at a specified temperature. Use data obtained by this method to predict the astmm 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.

Inspection Validating the specifications, value and safety of your x746 materials, products and assets. Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. Due to copyright restrictions, we are not able to provide copies of standards. Plastics and elastomers are used in many applications requiring low-temperature flexing with or without impact.

Brittleness Temperature ASTM D746 ISO 974

It is utilized primarily for plastics and elastomers. Precision grinding and EDM processes ensure true parallelism and multi-plane dimensional accuracy. Test temperatures, number of failures and the determined brittleness temperature. 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.

Assurance Testing Inspection Certification.

CCSi UltraLife specimen cutting dies are manufactured from homogenous, solid, high carbon content A2 tool steel. Specimens are secured in the customer specified specimen holder A or B with a torque wrench at xstm in-lb. The procedure is repeated at a lower temperature until enough data is generated to determine ashm brittleness temperature.

Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes.

It does not, necessarily, determine the lowest temperature at which the subject material may be used.

A protective coating of industrial enamel is applied to the non-cutting surfaces before undergoing a rigorous final inspection.

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

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. CCSi UltraLife specimen cutting dies are individually serialized, hand-honed, and mirror polished.

When testing plastic sheeting for impact brittleness, use Test Method D 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 rubbers for impact brittleness use Test Method D Asym our network of over 43, people in 1, laboratories and offices in countries, Intertek provides quality asfm safety solutions c746 a wide range of industries around the world.

V746 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.
