ACCESSIBLE PARTS
Test finger
Parts of ME EQUIPMENT that are to be regarded as ACCESSIBLE PARTS are identified by inspection and where necessary by test. In case of doubt, accessibility is determined by a test with the standard test finger shown in Figure 6, applied in a bent or straight position:
– for all positions of ME EQUIPMENT when operated as in NORMAL USE,
– even after opening of ACCESS COVERS and removal of parts, including lamps, fuses and fuseholders, without the use of a TOOL or according to the instructions for use.
The standard test finger is applied without appreciable force in every possible position, except that ME EQUIPMENT intended to be used on the floor and having a mass in any operational condition exceeding 45 kg is not tilted. ME EQUIPMENT which, according to the technical description, is intended for mounting into a cabinet, is tested in its final mounting position.
Openings preventing the entry of the standard test finger of Figure 6 are mechanically tested by means of a straight unjointed test finger of the same dimensions, which is applied with a force of 30 N. If this finger enters, the test with the standard test finger of Figure 6 is repeated, the finger being pushed through the opening if necessary.
Test hook
ME EQUIPMENT openings are mechanically tested by means of the test hook (see Figure 7), if the hook can be inserted.
The test hook is inserted in all openings in question and is subsequently pulled with a force of 20N for 10 s and in a direction substantially perpendicular to the surface in which the relevant opening is present. Any additional parts that have become accessible are identified by using the standard test finger of Figure 6 and by inspection.
