请大家注意标准的意思,不要断章取义:
( _2 Z7 x' d: R' e2 q, b8 K9 J1) 首先看标准的这句"30.1 External parts of non-metallic material, parts of insulating material supporting live parts including connections, and parts of thermoplastic material providing supplementary insulation or reinforced insulation,"
h5 o6 @, a, \. m0 T要注意前面这句"30.1 External parts of non-metallic material"$ g" X- V: s- X. l# W+ M, b! h( a
意思是"对于非金属材料制成的外部零件" 它和后面的两种材料是平行的.并未包含在"支撑带电部件的的绝缘材料"; "起附加绝缘和加强绝缘的热塑性材料" 里面..
0 F: E# \5 K4 J U8 E' g( [* u
: ]4 s8 \3 b$ H" O, d! F2) 然后根据yyfyqzy 对其产品的描述, 其洗脚盆材料既不是"支撑带电部件的的绝缘材料" , 也不是"起附加绝缘和加强绝缘的热塑性材料".: B* c2 j- F* i% Q8 p+ {
. F" O% i' Q: m6 ]7 P7 G0 T
本人觉得, 工程师对洗脚盆材料做球压测试所取的温度,应该是根据其在11章做温升时, 所测得的" 紧贴发热丝处的温度"再加上烘箱的温度.' G, C* {; w, s
这样才符合标准" The test is carried out at a temperature of 40 °C ± 2 °C plus the maximum temperature rise determined during the test of clause 11, but it shall be at least$ Z+ U8 h) B# H' g
– 75 °C ± 2 °C, for external parts" |
