Compliance is checked by inspection.

6.1.6 luminaries cord should be observed in addition to the hand-held storage device fixture. The structure of the device should be easily wound cord

No storage or damaged.

Compliance is checked by inspection.

6.2 Mechanical strength

6.2.1 General inspection lamp should be readily adjusted and maintained at the adjusted position.

Compliance is checked by inspection.

6.2.2 tested in GB 9706.1 Chapter 24, a check of the general formula movable imbalance should not be.

Protection means a) protect the bulb from damage should the lamp axial direction along the receiving 250N tension, over 1min.

Protective devices in its place.

b) be fitted with a suitable length GB lamps flexible cables and cords in claim 7000.13 10.2, shall withstand twice impact test,

When the test of the lamp toward the fixed brick, stone, concrete or the like solid material strikes the wall steel baffles, as shown in FIG.

Baffle size should be 40mm × 40mm × 5mm, at right angles down fillet with a 5mm radius. When the shutter installation, in contact with the wall,

Or, if necessary, brought into contact with a wall of the contact pad clad.

Not equipped handheld bulb lamps shall observe its hanging flexible cable or cord, indicated in FIG. 1 point "a" at the edges of the baffle plate rests, suspension

At a point 400mm above the baffle. Then, the shutter should be pulled away from the lamp and perpendicular to the wall until the cable or wire in a horizontal state.

In this manner the sample dropped toward the shutter 3 times. Then suspending the lamp at the point of impact that the position "b" of the same drop
