Temperature tester. (Instruments).The TR 2200 temperature retraction tester measures the effects of low temperature on rubber, plastic and other elastomeric materials. Meeting and exceeding ISO (1) See ISO speed. (2) (International Organization for Standardization, Geneva, Switzerland, www.iso.ch) An organization that sets international standards, founded in 1946. The U.S. member body is ANSI. 2921 and ASTM ASTM abbr. American Society for Testing and Materials D-1329, the TR 2200 allows the accurate evaluation of crystallization Crystallization The formation of a solid from a solution, melt, vapor, or a different solid phase. Crystallization from solution is an important industrial operation because of the large number of materials marketed as crystalline particles. and the comparison of rubber and rubber-like sample viscosity at low temperatures, according to the company. An operator stretches a sample, often to 50%, 100%, 150% or 200% of the original length, cools it in a bath solution like methanol or silicone grease, then releases the sample and allows it to retract TO RETRACT. To withdraw a proposition or offer before it has been accepted. 2. This the party making it has a right to do is long as it has not been accepted; for no principle of law or equity can, under these circumstances, require him to persevere in it. . Windows-compatible Benzwin software allows retraction point calculation and comparison. A single sample can be analyzed in different conditions, and different samples can be compared. The TR 2200 reports an elastomer's low limit operating temperature. It also details a sample's percentage of retraction at different temperatures. And it allows the determination of a temperature range in which a sample is elastic. The TR 2200 is often used with a BPT BPT Bridgeport (Connecticut) BPT Best Practicable Control Technology BPT Best Practicable Control Technology Currently Available BPT BP Prudhoe Bay Royalty Trust (stock symbol) BPT Boston Playwrights' Theatre 2100, a high accuracy brittlepoint tester, to gauge a material's suitability for low temperature use, according to the company.
