Technical Standard

Sheng Yang provides products maily about cable-based fixed head. In order to understand the consumers'needs in wire and cable industry have, wevery concerned about wire and cable industry standards and related policies. For the waterproof and dustproof (IP protection), fireproof (94v grade), explosion-proof anti-magnetic (EMC shielding - electromagnetic compatibility), environmental pollution and other needs, we developed a variety of high quality productsmeetdomestic and international standards, our products types are available to meet the needs of different industry users (product navigation).
IP protection level
The first digit indicates the dustproof index
0 means no protection
1 can prevent more than 50mm solid hazards. (Accidental hand contact)
2 can prevent the hazards of the solid more than 12mm. (A finger-sized object)
3 can prevent more than 2.5mm solid hazards. (Thin wire, etc.)
4 can prevent more than 1mm of solid hazards. (Thin wire, etc.)
5 can prevent the hazards of dust.
6 completely prevent the hazards of dust.
The second digit indicates the water resistance index
0 means no protection
1 can prevent the vertical fall into the water hazards
2 can prevent vertical direction below 150 angle direct sprinkler harm
3 can prevent vertical direction below 600 angle direct sprinkler harm
4 can prevent the hazards of direct water spray from all directions
5 can prevent the hazards of low pressure water jetting from all directions
6 can prevent the hazards of high pressure water jetting from all directions
7 can prevent the risk of immersion between 15cm~1m
8 can prevent long-term submersion hazards under pressure
Fire 94V grade division
Plastic flame retardant grade by HB, V-2, V-1 to V-0 step by step increase:
HB: lowestlevelinUL94 standard flame retardant grade. It is required that for samples of 3 to 13 mm thick, the burning rate is less than 40 mm per minute; samples less than 3 mm thick, the burning rate is less than 70 mm per minute; or extinguished before the 100 mm mark.
V-2: After two 10-second burn tests on the sample, the flame is extinguished in 60 seconds. There can be a burning thing falling.
V-1: After two 10-second burn tests on the sample, the flame is extinguished in 60 seconds. Can not have a burning thing falling.
V-0: After two 10-second burn tests on the sample, the flame is extinguished in 30 seconds. Can not have a burning thing falling.
