30 Position Shear Test Oven


Product Overview


  • 4 segment programmable controller, capable of performing SAFT ramped temperature testing
  • Maximum oven operating temperature of 500°F (260°C)
  • Temperature control accuracy of oven ± 0.5°F at 410°F (1°C at 210°C)
  • Temperature distribution accuracy of oven ± 1.5°F at 500°F (2.8°C at 260°C)
  • Oven is capable of achieving a temperature rise of 2°F (1°C) per minute (dependent on thermal mass)
  • The switch unit of the 30 Bank Shear fills approximately 50% of the interior volume in the oven
  • Stainless steel interior construction of the oven
  • Forced-air circulation type oven (convection)
  • Vent hole in rear of oven for accessory access
  • Easy-open oven door latch minimizes disruption of testing
  • Over-temperature protection and other safety features designed into oven electronics
  • RS-232 serial interface to controller, includes programming and data-logging software
  • 4,000 watt heating capacity
  • Standard oven input voltage - 208 VAC, 3-Phase, (50/60 Hz)
  • Shears are designed to be used with weights from 100gr to 1000gr
  • Any weight which is larger than the 1000gr requires the S-EXT(Shear Extension) accessory
  • The largest weight that can be safely used with the shear stand is 3000gr

Get unmatched results when performing heat-fail temperature shear testing of hot melt and pressure sensitive adhesives with the ChemInstruments 30 Position Shear Test Oven. This forced-ventilation shear test oven includes a ramping controller that complies with the SAFT test method ASTM D4498. The variability of SAFT tests depends on the mass in the oven, specific heat factors, wattage of the heating system, fan speed, program and operator technique. The 30 Position Shear Test Oven is the result of ChemInstruments' development of a standard rack, controller and oven combination, which greatly aids in producing uniform results between laboratories using the system.
