For tests of 9.2.3 to 9.2.9, a fixed luminaire intended for mounting with its body in contact with
a surface shall be tested with an expanded metal spacer interposed between the luminaire and
the mounting surface. The spacer shall be at least equal in overall size to the projection of the
luminaire, and have dimensions as follows:
Longway of mesh 10 mm to 20 mm
Shortway of mesh 4 mm to 7 mm
Strand width 1,5 mm to 2 mm
Strand thickness 0,3 mm to 0,5 mm
Overall thickness 1,8 mm to 3 mm

If the installation instructions indicate that a drip-proof luminaire is for ceiling or under-canopy
mounting, the luminaire shall be attached to the underside of a flat board or plate which
extends 10 mm beyond that part of the luminaire perimeter in contact with the mounting
surface.作者: 622 时间: 2012-1-27 16:32
