Test Chain
1. Introduction
Test chain is designed according to GB7000.1 and IEC60598-1 clause 4.26.3 & figure 29. It is to apply a prevent the impairing of safety due to unintended short-circuiting of uninsulated accessible SELV part of opposite polarity. The test chain is made by copper zinc alloy (Cu: 30%, Zn: 37%) , the chain shall have a resistance value of 2.5Ω/m±20% when stretched with a load of 200g/m.
