WM--P1 SERIES WORKSTATIONS
5TEST AND INSPECTION
5.1 Power supply
(1) Check the power supply cable and plug for excessive protrusion, twists, deformation or other irregularities.
5.2 Castor security
(1) Check the security of castors at six--monthly intervals. If loose use castor spanner ( K10005023) fitted to a standard 1/2”
drive torque driver to tighten to a torque of 30Nm.
If castor spanner ( K10005023) is not used, then torque value on the driver should be set to 38Nm. Refer to Chap 6.6.
5.3 Castors - electrical resistance test
NOTE
This test is only applicable to workstations fitted with ’anti--static’ castors, indicated by a yellow wheel centre or
swivel bearing collar, or a yellow dot on the tyre.
(1) Ensure that the workstation power cable is disconnected from the wall socket.
(2) Thoroughly clean each of the tyres.
(3) Roll a castor onto a metal plate which is insulated from the floor.
(4) Using a proprietary insulation tester working at 500Vdc, measure the resistance between the castor mounting point and
the plate. In cases where it is difficult to attach the test lead directly to the the castor mountings it is permissible to
connect to exposed metalwork (such as a screw head) on the base of the workstation, provided that it is electrically
connected to the castor mounting point.
The average resistance should not exceed 100kfor castors rated as ’Conductive’ according to ISO22881:2004,
measured at three different points on the tyre’s circumference.
(5) Repeat the procedure on the other castors.
