| Inspecting item | Technical Requirements | Inspecting type |
| Routine test (Before leaving factory) | Type test |
| Package | Each small package contains one fiber optic splice closure,
together with its accessories, tools, installation manual and
packing list. | full |
At least 3 sets sampled each time
|
| Appearance | Intact in shape, no burrs, bubbles, chaps, pores, warps, impurities
and other defects, all background colors should be even and
continual. |
| Sign | There is a clear sign on the housing, such as name and model of the
product, etc. |
| Fiber storage device | The fibers reserved are to be winded in fiber optic splice tray
(FOST), the length of fibers housed in FOST is >1.6m, the curved
radius is >30mm. During the installation and maintenance, there
should be no attenuation on fibers. |
At least 3 sets sampled each time
|
| Electrical jointing device | Inside FOSC: metallic components of fiber cables has the functions
of electrical putting through, earthing connection and
disconnecting. It is possible to install earthing deriving device
outside the housing |
| Sealing performance | After sealing according to the stipulated operation procedures, the
injected air pressure is 100KPa±5Kpa, when immersed in clean water
of normal temperature for 15 minutes, there should be no air
bubbles, then observed for 24 hours, there should be no change of
air pressure. |
| Re-sealing performance | After reopening and resealing according to the stipulated operation
procedures, the injected air pressure is 100KPa±5Kpa, when immersed
in clean water of normal temperature for 15 minutes, there should
be no air bubbles, then observed for 24 hours, there should be no
change of air pressure. |
| Pull | Bearing pull is ≧ 800N at axle orientation, there should be no
breakage on the housing. |
| Punching | Bearing pressure of 2000N/10cm for 1 minutes, there should be no
breakage on the housing |
| Impact | Bearing impact energy of 16N•m, 3 times of impacts there should be
not breakage on the housing |
| Bending | The spot between the FOSC and seal fitting can bear bending tension
of 150N at bending angle of ±450 for 10 circles, there should be no breakage on the housing |
| |
| Torsion | Bearing torsion 50N•m, 10 circle at torsion angle±900, There should be no breakage on the housing. |
| Temperature circle | Injected air pressure of 60KPa±5 KPa, the temperature circle
ranging from -40℃~+65℃, 10 times of the circular tests (one
circular consists of high temperature for 2 hours + indoor
temperature for 2 hours + low temperature for 2 hours + indoor
temperature for 2 hours ) when the pressure declines, the amplitude
is ≦5Kpa, immerse the swatch in clean water of normal temperature
for 15 minutes, there should be no air bubbles. |
| Voltage resistance strength | After sealing the FOSC according to the stipulated operation
procedures, immerse it in clean water of normal temperature in 1.5m
depth for 24 hours, there should be no breakdown or arc over
between the metallic components of the FOSC, between metallic
components and the ground at DC 15KV for 1 minutes. |
| Isolating resistance | After sealing the FOSC according to stipulated operation procedure,
immerse it in clean water in 1.5m depth for 24h, the isolating
resistance between the metallic components of the FOSC, between the
metallic components and the ground should be ≧ 2×104MΩ. |
