Send us a request Wilton UK: Brittle failure is defined by ASTM D as fracture into 2 or more pieces, or any crack visible to the unaided eye. The results may be used to predict the behavior of plastic and elastomeric materials at low temperatures.

Precision grinding and EDM processes ensure true parallelism and multi-plane dimensional accuracy. Historical Version s – view previous versions of standard. CCSi UltraLife specimen cutting dies are manufactured from homogenous, solid, high carbon content A2 tool steel. Test temperatures, number of failures and the determined brittleness temperature. Specimens are secured in the customer specified specimen holder A or B with a torque wrench at 5 in-lb.

However, this holds only under conditions in which the material is subjected to deformations similar to those imposed in the test. Where highly technical manufacturing techniques and processes end When testing rubbers for impact brittleness use Test Method D 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.

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.

Two routine inspection and acceptance procedures are also provided. When testing plastic sheeting for impact brittleness, use Test Method D Due to copyright restrictions, we are not able dd746 provide copies of standards.

ASTM D employs three cutting dies: Assurance Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. There are three specimens: Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards.

CCSi UltraLife specimen cutting dies are individually serialized, hand-honed, and mirror polished. A protective coating of industrial enamel is applied to the non-cutting surfaces before undergoing a rigorous final inspection.

All purchase orders must be postmarked or recieved no later than January 5 thto qualify.

ASTM D Specimen Cutting Dies

Standards can be obtained from appropriate standards authorities. It does not, necessarily, determine the lowest temperature at which the subject material may be used. Plastics and elastomers are used in many applications requiring low-temperature flexing with or without impact. Each undergoes multi-axis precision grinding and conventional, plunge, or wire EDM Electrical Discharge Machining processes 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.
