大写BG是错误写法,正确写法为GB,指国家标准。GB/T是指推荐性国家标准(GB/T),T在此读推。推荐性国标是指生产、交换、使用等方面,通过经济手段或市场调节,而自愿采用的国家标准。
这类标准任何单位都有权决定是否采用,违反这类标准,不承担经济或法律方面的责任。但是,一经接受并采用,或各方商定同意纳入经济合同中,就成为各方必须共同遵守的技术依据,具有法律上的约束性。GB通常指的是强制性的,其中若有部分内容不属强制性的,亦会有说明。
根据国家标准,珠宝首饰在出厂前都应在首饰托上打印出必须的标识,这些标识包括:厂家代号、纯度、材料以及镶嵌首饰主石的重量和标识(0.10克拉以上的钻石)。
【英文介绍/For English】:
Capitalized BG is wrong spelling, correct spelling is GB, which refers to the national standard. GB/T refers to the recommended national standard (GB/T), and "T" reads "push" here. Recommended national standards refer to national standards that are voluntarily adopted through economic means or market regulation in terms of production, exchange, and use.
Any unit of this type of standards has the right to decide whether to adopt or not, and will not bear economic or legal responsibility for violating such standards. However, once it is accepted and adopted, or the parties agree to incorporate it into the economic contract, it becomes the technical basis that all parties must abide by and is legally binding. GB usually refers to mandatory, if some of the contents are not mandatory, there will be instructions.
