During the test there shall be no failure or movement about the point of attachment and alter either part of this test there shall be no permanent set exceeding 1
5.6.6 Where means for angular adjustment are provided, there shall be provision for positive locking after any such adjustments have been effected.
5.6.7 Floodlights for use outdoors shall be resistant to the vibrations which may occur during normal use.
5.6.8 Glass covers shall either consist of a glass that fractures into small pieces, or shall be provided with a guard of sufficiently small mesh or the use of a film-coated glass that retains glass fragments.
For flat glass covers compliance is checked by inspection, and if the glass is not provided with a guard by the following test.
The glass component is supported over the whole area to ensure that particles will not be scattered upon fragmentation and that movement of the particles is prevented. Shatter the glass with a centre punch at a point 30 mm from the mid-point of one of the longer edges of glass towards the centre. Within 5 ml,, of fracture count the particles in a square of 50 mm side located approximately at the centre of the area of coarsest fracture but always within the confines of the glass.
NOTE — Where possible, the area of measurement should not be within 30 mm of any edge, hole or machining of the glass.
A glass is deemed to have passed the test if the number of particles in the square of 50 mm side is more than 60; glass splinters and pieces less than the lull thickness of the glass are excluded from the count. For glasses of small size where a 50 x 50 area is not possible, the number of pieces necessary in the count is proportionately reduced.
NOTE — In the count of the total number of particles in the square of 50 mm side, the particles in the centre of the square plus those at the edge taken Into account. For counting purposes of particles at the edge of the square, It Is recommended that all pieces intersected by two adjacent sides be included and all particles intersected by the two other sides be ignored, see figure 1
A suitable method of counting the particles is to place a square of 50 mm side, of transparent material, over the glass and mark a spot of ink as each particle within the square is counted.
For the count at the edge of the square, select any two adjacent sides of the square and count all the particles intersected by these: exclude all other intersected particles.
NOTE — For glass covers formed from a flat plate, a test is under consideration.
