Rubber low temperature embrittlement instrument is measured shocks brittle transition temperature and shock critical temperature embrittlement testing machine in the vulcanization of rubber and plastic low temperature environment. Rubber low temperature embrittlement instrument is measured shocks brittle transition temperature and shock critical temperature embrittlement testing machine in the vulcanization of rubber and plastic low temperature environment. Test piece loaded clip with a single type just installed a set of four and can be installed multiple group type. Cooling compressor refrigeration. Single type has four sample clip device group, you can also install 20 test pieces. In the sample not in the freezer in the case, only to change the dial can be tested. Multiple sets of type (type) can be continuously samples tested by the conversion cartridge holder base, you can save time samples back in place, meet a lot of samples of each test. Rubber low temperature embrittlement instrument applicable standards JIS K6261 ISO812 (vulcanized rubber low temperature test method - low temperature embrittlement impact test) JIS K7216 (plastic low temperature embrittlement test method) JIS K6261, K7216, ASTM-D746, ISO-974 Sample size and shape sample size and shape according to JIS K6261 ISO812 (vulcanized rubber low temperature test method - low temperature embrittlement impact test) JIS K7216 (plastic low temperature embrittlement test method) JIS K6261, K7216, ASTM-D746, ISO-974 provisions of rubber low temperature embrittlement technical parameters: sample Chuck: five samples simultaneously holding fixture (multiple group type can simultaneously holding 20 samples) hammer speed: 1.4-2.4m / sec (adjustable) figures show 0.00m / sec hammer top radius: 1.6 ± 0.1mm cold tank: stainless steel (internal) contains stirrer hot medium: The main use of ethanol temperature range: -40 ℃ ~ 20 ℃ Cooling system: Overlay compressor refrigeration temperature rise of the system: 1.5KW heater temperature control system: digital temperature controller sample adjustment timer: digital timer safety devices: leakage circuit breaker, thermal protector rubber low temperature brittleness test machine Main features: chuck conversion section at a 90 degree angle, four groups chuck can be mounted radially shape, when the rotation handle, convert chuck can boot into combat test state. Samples Sample striking position against the state at a predetermined speed by alternately hammer blow chuck sample in the sample folder strike. Test tank (cold tank) through the use of dual cooling motivation system may be cooled to -70 ℃. Rubber low temperature brittleness test control part of the electronic circuit device in accordance with the given process control, is inherent in the internal machine rubber low temperature brittleness tester relevant information 1.GB/T 15256-94 Determination of vulcanized rubber low temperature brittleness (multiple test piece method ) 2 GB / T1682-94 Determination of vulcanized rubber low temperature brittleness (single test piece method)
