Brittleness Temperature Tester is intended to measure the brittleness temperature of vulcanized rubber, which is the lowest temperature at which none of a set of specimens fractures due to low-temperature embrittlement when tested under the specified conditions.
Product Description
Brittleness Temperature Tester is intended to measure the brittleness temperature of vulcanized rubber, which is the lowest temperature at which none of a set of specimens fractures due to low-temperature embrittlement when tested under the specified conditions.
The low-temperature brittleness tester can be used to make comparative identification of functional performance for the non-rigid plastic and other elastic materials under the low-temperature condition and measure the pros and cons of low-temperature properties of different rubber materials and compound rubbers with different formulas. Therefore, the brittleness temperature tester is one of the vital rubber instruments in the quality inspection of scientific research and controlling the production process.
Test standard
ISO 812 Rubber, vulcanized or thermoplastic determination of low temperature brittleness
ISO 974 Plastics determination of the brittleness temperature by impact
ASTM D746 Brittleness temperature of plastics and elastomers by impact
JIS K6261 Rubber vulcanized or thermoplastic determination of low temperature properties

Product Characteristics
A test piece is clamped in the clamp and immersed into the constant low-temperature container with the freezing medium to precool for 5 minutes. A striking edge is delivered to impact the specimen at the linear velocity of 2 ± 0.2 m / s. The operator examines each test piece to determine whether or not it has failed. According to different results, the operator lowers or raises the temperature of the cooling medium and continues the test until the brittleness temperature of the test sample is measured.
