Brittleness Point Testers: Critical Tools for Material Durability
Rubber Low Temperature Brittleness tester is used to measure the highest temperature when vulcanized rubber is impacted to damage under special condition, and the temperature is called brittle temperature. HOTLINE +86 132-6746-6269 [email protected]. Home. Home. About us.The following test methods will be described and it must be noted that they may not give the same result or range the materials in the same order. Table 1 Low temperature test methods • Brittleness Point ISO 812 • Low Temperature compression set ISO 815 • Low Temperature stiffening, Gehman Test ISO 1432 • Temperature Retraction, TR-test .Lowest temperature for the rubber brittleness tester can be - 80°C; Specifications : Temperature control range: Room temperature to -70 ℃ (room temperature ≤ 25 ℃） Temperature accuracy: ± 0.3 ℃ Impact speed: 0℃ to -30℃ around 2.5 ℃/min -30℃ to -40℃ around 2.5 ℃/min .CCSi features the Gibitre™ Temperature Retraction (TR) and Brittleness Point Tester for the evaluation of the effects of crystallization and for the comparison of the viscoelastic properties of rubber and rubber-like materials at low temperatures, as described in ASTM D1329, “Standard Test Method for Evaluating Rubber Property—Retraction at Lower Temperatures (TR Test).” 1
Brittleness temperature is the temperature at which 50% of the tested specimens exhibit brittle failure at specified impact conditions. It is utilized primarily for plastics and elastomers. Test Procedure: Specimens are secured in the customer specified specimen holder (A or B) with a torque wrench at 5 in-lb.3.2.1 Test Method A—The determination of the lowest temperature at which rubber vulcanizates will not fracture or crack (refer to 9.1). 3.2.2 Test Method B—The determination of the lowest temperature at which rubber-coated fabrics will not fracture or exhibit coating cracks (refer to 9.2). 3.2.3 Test Method C—Testing at a specified . 4.1 These test methods cover the evaluation of rubber materials or fabrics coated therewith subjected to low-temperature flex with an impact under well-defined conditions of striker speed. The response is largely dependent on effects of low temperatures such as crystallization, incompatibility of plasticizer, or the inherent dynamic behavior of the material itself.
Product Description: Qualtech Products Industry Brittleness Test System is an advanced Low Temperature Brittleness Tester to instantly measure the Brittleness Performance of samples at the touch of a button.. The Brittleness Test is performed by subjecting a sample to stress.
