Technical   Data
 
 Resistance(R*5)
Requirement:R*5 within the scope of the standard 
Test method: *5℃±0.*5℃  constant temperature tank test
 
4. B-value
Requirement: B value within the scope of the standard
Test method:In high accuracy constant temperature tank, code according to the B value measured at both temperature resistance, then the following formula.
Bt1/t2=ln (Rt1/Rt2)/(1/(t1***3.*5)*1/(t2***3.*5))
 
Insulation resistance
Requirement:≥ **0MΩ
Test condition:At room temperature, applied voltage **0V DC
 
withstand  voltage
Requirement:No breakdown
Test condition:At room temperature, applied voltage AC ***0V 5s for a second, max current 0. 5mA.
 
Thermal dissipation factor(δ)
δ≤2.5mW/℃;
Requirement:δ≤2.5mW/℃;
Test method:The product will be join with the following circuit at *5±0.5℃ in still air.

Thermal time Constant(τ)
Requirement:CWF1τ≤7s,CWF2åž‹τ≤*0s,CWF3τ≤9S
Test method:In the water, When the products be put into the water at *5℃ from the water at *0℃, Thermal time constant is the time that cost by the resistance becoming to be the value at*3.2%.
