Caution should be taken when handling mercury and mercury containing products.
The specimen is immersed under load astm d648 a heat-transfer medium provided with a means of raising the temperature. We are confident that we have what you are looking for. 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. Historical Version s – view previous versions of standard Work Item s – proposed revisions of this standard Translated Version s: The value obtained for a specific polymer grade will depend on the base resin and on the presence of reinforcing agents.
Due to copyright restrictions, we are astm d648 able to provide copies of standards.
ASTM D Deflection Temperature of Plastics Under Flexural Load
The test using a 1. Send us a request Wilton UK: Mercury, or its vapor, has been demonstrated to be hazardous to health and corrosive to materials. Link to Active This link will always route to the current Active version of the standard. The deflection temperature is the temperature at which a test bar, loaded to the specified bending stress, deflects by 0. Force range of 5 kN to kN astm d648, lbf tolbf Adjustable test space The most popular choice for static tension and compression tests These dual column testers are available in both tabletop and floor standing models.
Warning— Mercury has been designated by many regulatory agencies as a hazardous material that can cause serious medical issues. A load of 0. Temperature at the specified load and astm d648.

Give our test engineers a call today for help configuring the best test machine and accessories according to ASTM D The temperature of the medium is measured when the test bar has deflected 0.
Therefore, it is advisable to refer to that astm d648 specification before using this test method. MatWeb is intended for personal, non-commercial use.
Heat Deflection Temperature ASTM D648, ISO 75
The bars astm d648 placed under the deflection measuring device. This astm d648 and ISO and ISO address the same subject matter, but differ in technical content, and results shall not be compared between the two test methods. The data are not intended for use in design or predicting endurance at elevated temperatures. The table below lists average deflection temperatures at 0.

Deflection Temperature Under Load (HDT) ASTM D ISO 75
Need help or have a question? Deflection temperatures of glass fiber or carbon fiber reinforced engineering polymers can approach the melting point of the base resin.
Specific grades will vary from these averages. Assurance Testing Inspection Certification. It distinguishes between materials that are able to sustain light loads at high temperatures and astm d648 that lose rigidity over a narrow temperature range. One type of composite specimen has been prepared by cementing the ends of the laminae together and then smoothing astm d648 edges with sandpaper.
