1 Scope

GB/T 15663.8-2008 is the Chinese national standard on terms relating to coal mining - part 8: mine safety, in the field of generalities, terminology and documentation. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it.
