Laboratory Testing IEC60598 Safety Test Chain
Laboratory testing IEC60598 Safety Test Chain
1.Instructions:
- Measuring chain resistance, to ensure that the range of 2.5 ± 20% Ω .
- Measuring distance space of the SELV two parts, denoted as X, unit (/ cm).
- Test chain ends hanging standard weight =15*X*g or 250g counterweight.
- Install the thermocouple wire on proper position of the tested sample, and connecting with temperature inspecting instrument.
- Sample access 0.9~1.1 times the rated voltage of power supply.
- Placement test chain, short-circuit test.
2.Application:
-
The test chain is strictly designed and manufactured according to IEC60598-1,GB7000.1.4.26 standards.
It mainly used for lighting without insulation, accessible and opposite SELV part accidental short circuit protection test.
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.
