Introduction
This Contact Heat Transmission Tester is designed according to
EN702 standard,and it can meet requirements of Chinese standard
AQ6103-2007 Protective gloves for welders.The test results includes
contact temperature,time of starting test,threshold time etc.
The principle is:under set contact temperature,the measuring
protective fabric contacts heating column while bearing 49N
pressure,the time of temperature raising 10℃ from initial
temperature is threshold time,which is used to evaluate thermal
protective property.
Standards:
EN 702:Protective clothing - Protection against heat and flame -
Test method: Determination of the contact heat transmission through
protective clothing or its materials;
ISO 12127-1:test method for the determination of contact heat
transmission. It is applicable to protective clothing (including
hand protectors) and its contituent materials intended to protect
against high contact temperatures. Application of ISO 12127-1:2007
is restricted to contact temperatures between 100 °C and 500 °C.
Features
1. Contact Heat Transmission Tester adopts high temperature
resisting metal heating element,contact diameter is ￠25.2±0.05 mm.
2. Heating temperature range is ambient~500℃,the HMI can show it
directly.
3. Contact area of calorimeter is ￠25±0.05×D5±0.02mm,measuring
range is not less than 500℃.
4. Contact force:49N,contact speed:5mm/s,calorimeter is controlled
by Servo motor,which is automatic up and down.All test process are
automatically controlled by program.
5. The platform of heating element can be moved horizontally,which
is easy for put sample and make sure the operator’s safety.
6. LCD display,PLC automatically records start time,threshold
time,end temperature of threshold time,real-time temperature.
