Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. This test method has been found useful asgm specification d74, but does not necessarily measure the lowest temperature at which the material is suitable for use.
Global Reach Intertek is the industry leader with over 42, people in 1, locations in over countries. Brittle failure 7d46 defined by ASTM D as fracture into 2 or more pieces, or any crack visible to the unaided eye. Send us a request Wilton UK: It does not, necessarily, determine the lowest temperature at which the subject material may be used. However, this holds only under conditions in which the material is subjected to deformations similar to those imposed in the test.
There are three specimens: When testing rubbers for impact ashm use Test Method D 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.
Two routine inspection and acceptance procedures are also provided.

Assurance Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. CCSi UltraLife specimen cutting dies are manufactured from homogenous, solid, high carbon content A2 tool steel.
Plastics and elastomers are used in many applications requiring aatm flexing with or without impact. 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.
The procedure is repeated at a lower temperature until enough data wstm generated to determine a brittleness temperature. Link to Active This link will always route to the current Active version of the standard. Standards can be obtained from appropriate standards authorities.

Need help or have a question? The results may be used to predict the behavior of plastic and elastomeric materials at low temperatures. CCSi UltraLife specimen cutting dies are individually serialized, hand-honed, and mirror polished. Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. 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.
A protective coating of industrial enamel is applied to the non-cutting surfaces before undergoing a rigorous final inspection. 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.
When testing plastic sheeting for impact brittleness, use Test Method D The specimen holder is lowered into a bath at a specified temperature. Where highly technical manufacturing techniques and processes end Please Request a Quotation for current pricing and delivery.
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.
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.
