Whakaaturanga tuhi whaanui kaore he tohu tohu

Tohua te nama paerewa me te tohu tohu karaehe e tata ana ki te poraka taitara o te tuhi, ki nga whakaritenga hangarau me nga tuhinga hangarau (penei i nga paerewa hinonga).Hei tauira, i te wa e whiriwhiri ana i te taumata waenga, ko te tapanga e whai ake nei:

GB/T 1804-m

Ko nga hanganga karekau i tohuhia ki te paanui ahuahanga i roto i nga tuhi ka tohua kia rite ki te karaehe i roto i te GB / t1184-1996 "whakaaetanga ahuaahanga me te tuunga kaore he uara o te manawanui takitahi".[1]
