What’s the China PV junction Box inspection standard

 China PV junction Box test content and methods:1) The manufacturer, specifications, appearance, anti-pull connectors, wire bayonet bite force, bite force diode discipline, cover the bite force, the diode voltage test.2) incoming sampling, production tracking test.
Test tools: tensiometer, pressure testing, Material: coated with tin

Testing methods:1) confirm the junction box manufacturer, model specifications2) Appearance: Check that there are defects that (should not be wiping), and the diode junction box and the number of internal defects.3) The tensile strength of the connector: the connector to the junction box, and then grip the junction box, with chest-test (tension> 10N) is qualified.4) leads bayonet bite force: the convergence zone put into the bayonet, with the tensiometer grip Shijia La force> 40N qualified.5) Cover the bite force: three consecutive launch, still need special tools to open for the pass.6) diode voltage: The voltage tester (1000VDC),

5 Inspection Rules: above all seized, one does not meet the test requirements are re-examining. If you still do not meet the 2) .3) .4) .5) .6) inspection requirements, and determines that the incoming batch is substandard.
