Product Description

Safety Test Chain for Lighting Short Circuit Protection Test


 

Introduction:
1, Standards: IEC60598-1  EN60598-14.26.3 
2, Test Chain is composed of copper and zinc alloy (Cu 63% Zn37%)without any surface treatment and coating ,
 200g/m load tensile resistance at 2.5±20%Ω according to IEC60598-1 standards.
 
Application:

1)Measuring chain resistance, to ensure that the range of 2.5 ± 20% Ω .
2)Measuring distance space of the SELV two parts, denoted as X,unit (/ cm).
3)Test chain ends hanging standard weight =15*X*g or 250g counterweight.
4)Install the thermocouple wire on proper position of the tested sample, and connecting with temperature inspecting  instrument.
5)Sample access 0.9~1.1 times the rated voltage of power supply.
6)Placement test chain, short-circuit test.
 
It mainly used for lighting without insulation , accessible and opposite SELV part accidental short circuit protection test.


Appliance:
The tip of the glow-wire is then brought smoothly into contact with the test specimen for a duration of 30 s ± 1 s. An approximate rate of approach and withdrawal of 10 mm/s to 25 mm/s has been found to be satisfactory. However, the rate of approach shall be reduced to near zero upon contact to avoid impact forces exceeding 1,05 N. In those cases where the material melts away from the glow-wire, the glow-wire shall not be kept in contact with the test specimen. Following the application time, the glow-wire and the test specimen are slowly separated, avoiding any further heating of the test specimen and any movement of air which might affect the result of the test. The penetration of the tip of the glow-wire into and through the test specimen shall be limited to 7 mm ± 0,5 mm.
 When forming the glow-wire , care shall be taken to avoid fine cracking at the tip.
