*JIS の規格番号

規格番号を決める規格とかってあるんでしょうか?
それとも[[工業標準化法]]またはその関係規則([[政令]])で
決まってるのかなあ?

=jis = jis-standard / jis-tr
=jis-standard = 'JIS' SP category SP number [year]
=jis-tr = 'JIS TR' SP category SP number [year]
=category = UALPHA
=number = 4DIGIT ["-" part-number]
=part-number = 1*DIGIT
=year = ":" 4DIGIT / obs-year
=obs-year = "-" 4DIGIT
