有的有要求哦
你可以查下标准里面的6 章节是描述marking and instruction 的。
对于警语欧洲标准不是强制要求的,如果要有要是不低于1.6mm
下面的是从UL60601 摘下来的。
6DV.1 The text of the marking prefaced with an upper case signal word ²CAUTION²,
²WARNING², or ²DANGER², shall consist of upper and lower case letters, in English, that
comply with the following:
a) All words comprising the text of the marking, excluding the signal word, shall
be in letters not less than 1,6 mm (1/16 inch) high, based upon upper case,
b) The signal word shall be in letters at least 2,8 mm (7/64 inch),
c) The letters shall be in contrast color to the background. Letters that are raised
or indented and do not have a contrasting color to the background are not
acceptable. |
