Auditing Consulting Sourcing Training. This test method has been found useful for specification dd746, but does not necessarily measure the lowest temperature at which the material is suitable for use. Inspection Validating the specifications, value and safety of your raw materials, products and assets. Global Reach Intertek is the industry leader with over 42, people in 1, locations in over countries. The procedure is repeated at a lower temperature until enough data is generated to determine a brittleness temperature.
Brittleness Point Tester for ASTM D, ASTM D, and ISO Tests
Two routine inspection and acceptance procedures are also provided. The results may be used to predict the behavior of plastic and elastomeric materials at low temperatures.
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 5 in-lb. It is the responsibility of the ast of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
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. Where highly technical manufacturing techniques and processes end Need help or have a question? Use data obtained by this method to predict the behavior of plastic and elastomeric materials at astn temperatures only in applications in which the conditions of deformation satm similar to those specified in this test method.
A protective coating of industrial enamel is applied to the non-cutting surfaces before undergoing a rigorous d7746 inspection. The specimen holder is lowered into a bath at a specified temperature. Each undergoes multi-axis precision grinding and conventional, plunge, or wire EDM Electrical Discharge Machining processes Precision grinding and EDM processes ensure true parallelism and multi-plane dimensional accuracy.
Plastics and elastomers are used in many applications requiring low-temperature flexing with or without impact.

ASTM D Specimen Cutting Dies
There are three specimens: Test temperatures, number of failures and the determined brittleness temperature. Standards can be obtained from appropriate standards authorities.
When testing plastic sheeting for impact brittleness, use Test Method D The quality of materials, design, and engineering serve to provide the highest specimen quality possible, over an extended service aatm.
