Performance testing 1. Mechanical performance: the grip force of the wire clamp is 1/10 bigger than the break force of the lead, It comply with GB2314-1997. 2. Temperature rise performance: under the condition of big current, the temperature rise of connector is less than that of connection lead. 3. Heat circle performance: conforms to GB/T2317.3-2000, the heat circle trial standard for electric fitting. 4. Waterproof insulation performance: conforms to the relevant testing requirements in Part 2 of GB/T13140.4-1998. 5. Resistance to corrosion performance: under the condition of SO2 and salt fog, it can do three times of fourteen days circle testing. 6. Environmental aging performance: under the circumstance of ultraviolet, radiation, dry and moist, expose it with change of temperature and heat impulse for six weeks. 7. Fire-proof performance: insulation material of the connector withstands glowing filament test. Conform to the requirements in Chapter 4-10 of GB/T5169.4. -
