Technical indexes

(1) Environment Condition:

Environment Temperature: -40??+60?

Atmospheric pressure: 70?106Kpa

(2) Electric property?

Insulation resistance between the metallic elements themselves and between metallic element and the earth is more than 2×10⁴MΩ;

The pressure resistance between the metallic elements themselves and between metallic element and the earth is 15KVDC/1min, Non-puncture, no arc-cover.

(3) Optic property:

The curvature radius of the spare fiber is over 37.5mm; no additional optic attenuation.

(4) Seal Performance:

When the closure is pressurized up to 100kPa and immersed in water for 15 minutes, no air bubbles; or observed for 24 hours, no change of air pressure.

(5) Re-entry Performance:

After 3 times of encapsulation according to the instruction, it still can be up to the seal performance standard.

(6) Mechanical Performance:

After all the following tests, the box and all the components inside don’t change, check through gently or open it if necessary.

When the closures are pressurized up to 60 kPa, it can still meet the seal performance standard after the mechanical performance test
