铭版也叫铭牌,
铭牌定义：产品投放市场后,固定在电机、电器或机械设备上需要向用户提供识别、铭记、使用指导等信息的标牌.
又称标牌,铭牌主要用来记载生产厂家及额定工作情况下的一些技术数据,以供正确使用而不致损坏设备.制作铭牌的材料有金属类和非金属类之分别：金属类有锌合金、铜、 铁、 铝、 不锈钢等：非金属类有塑料、亚克力、纸等.
例如电器,外包装上有纸制印刷的,电器上有金属板铭刻的,主要记载有产家名号、产品的额定技术数据等,中文铭牌上所采用的文字符号应一律使用中国法定的标准,进口产品投放市场需要备中文名牌的也应照此办理.
nameplate：
A nameplate identifies and displays a person or product's name.Name plates are usually shaped as rectangles but are also seen in other shapes,sometimes taking on the shape of someone’s name.The primary use of name plates is for informative (as in an office environment,where name plates are mounted on doors or walls in order to identify employees) and commercial purposes (as in a retail environment,where name plates are mounted on products to identify the brand).Whereas name tags tend to be worn on uniforms or clothing,name plates tend to be mounted onto an object (e.g.,cars,amplification devices) or physical space (e.g.,doors,walls,or desktops).Nameplates are also distinct from name plaques.Plaques are items of larger dimensions that are designed to communicate more information than a name and title.
