将公司现有的铭牌覆着力测试方法介绍,如有不当之处,有指教:
1。将铭牌粘贴在铭牌所贴的部件上,放入恒温箱中,恒温箱温度设定到11章测试铭牌处的最高温度再加上30℃,待温度稳定后,恒温1小时后,将其取出,冷却到常温。角部不翘起.
2、将铭牌粘贴在铭牌所贴的部件上,放入恒温箱中,恒温箱温度-20℃,待温度稳定后,恒温1小时后,将其取出,放置却到常温。角部不翘起.
当然也可以做个IEC 60335-1的7.14测试
7.14 The markings required by the standard shall be clearly legible and durable.
Compliance is checked by inspection and by rubbing the marking by hand for 15 s with a
piece of cloth soaked with water and again for 15 s with a piece of cloth soaked with
petroleum spirit.
After all the tests of this standard, the marking shall be clearly legible. It shall not be easily
possible to remove marking plates nor shall they show curling. |
