Formally confirming that your products and services meet all trusted external and sstm standards. 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.

Auditing Consulting Sourcing Training. Each undergoes multi-axis precision grinding and conventional, plunge, or wire EDM Electrical Discharge Machining processes Validating the specifications, value and safety of your raw materials, products and assets. Asgm can be obtained from appropriate standards authorities. Plastics and elastomers are used in many applications requiring low-temperature flexing with or without impact.

Brittleness Point Tester for ASTM D, ASTM D, and ISO Tests

Send us a request Wilton UK: Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. Where highly technical manufacturing techniques and processes end When testing rubbers for impact brittleness use Test Method D The procedure is repeated at a lower temperature until enough data is generated to determine a brittleness temperature. Link to Active This link will always route to the current Active version of the standard.

Brittle failure is defined by ASTM D as fracture into 2 or more pieces, or any crack visible to the unaided eye. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

Brittleness Temperature ASTM D746 ISO 974

The specimen holder is lowered into a bath at a specified temperature. Assurance 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.

Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards.

The brittleness temperature is determined by immersing the specimens in the specimen holder in a bath containing a aztm transfer that is cooled, usually by liquid nitrogen, carbon dioxide, or powdered dry ice, to a predetermined temperature for a period asstm three minutes.

Specimens are secured in the customer specified specimen holder A or B with a torque wrench at 5 in-lb. When asrm plastic sheeting for impact brittleness, use Test Method D However, this atm only under conditions in which the material is subjected to deformations similar to those imposed in the test. The quality of materials, design, and engineering serve to provide the highest specimen quality possible, over an extended service life. Test temperatures, number of failures and the determined brittleness temperature.

Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. Historical Version s – view previous versions of standard.

The results may be used to predict the behavior of plastic and elastomeric materials at low temperatures. ASTM D employs three cutting dies: There are three specimens: CCSi UltraLife specimen cutting dies are manufactured from homogenous, solid, high carbon content A2 tool steel.

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.

Assurance Testing Inspection Certification. Certification Formally confirming that your products and services meet all trusted external and internal standards. Due to copyright restrictions, we are not able to provide copies of standards. It does not, necessarily, determine the lowest temperature at which the subject material may be used. It is utilized primarily for plastics and elastomers. Need help or have a question?

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.

All purchase orders must asym postmarked or recieved no later than January 5 thto qualify. A protective coating of industrial enamel is applied to the non-cutting surfaces before undergoing a rigorous final inspection. CCSi UltraLife specimen cutting dies are individually serialized, hand-honed, and mirror polished.

Two routine inspection and acceptance procedures are also provided.
