请大家帮忙理解下面IEC60598-1 Section 9 标准中的要求。 0 S( I7 m" f3 x& a2 J 0 C V' |3 t K- w0 P2 b# w2 `% J. oFor tests of 9.2.3 to 9.2.9, a fixed luminaire intended for mounting with its body in contact with D5 w# l) q, la surface shall be tested with an expanded metal spacer interposed between the luminaire and * Q3 q! ~: C( I1 |7 Q. l!
