Kua pāngia te hunga katoa kua hoko mai i ngā taputapu ine tika o tāwāhi e te raruraru kotahi: ka taea te whakaahua i te hua tinana kotahi ki ngā paerewa ā-motu e rima, ia paerewa me tana ake pūnaha whakatauranga, ripanga manawanui, me ngā kupu. He mea nui te mārama ki ngā mea e tohua ana e ēnei paerewa - kaua e whakaarotia he tohu whakaae ka taea te whakawhiti - mō te hunga e hoko mai ana, e hanga ana rānei i ngā pereti mata, i ngā taha tika, i ngā taputapu ine karāhe rānei.
Ngā Paerewa Matua i te Tirohanga Poto
DIN (Tiamana) — E kapi ana te DIN 876 i ngā ātete papatahi mōngā pereti mataputa noa i ngā taumata e toru (00, 0, me te 1), ko te Tau 00 i rāhuitia mō te whakamahinga tohutoro taiwhanga. Ka aro te DIN 875 ki ngā taha tika, ā, ka hipokina e te DIN 650 ngā poraka-V. He whānuitia te whakamahinga o ngā paerewa Tiamana hei tohutoro i Ūropi me Āhia nā te mea he ripanga manawanui taipitopito e hono ana ki te rahi o te pereti.
ASME/GGGP (Te Hononga o Amerika) — I whakamahia e te mahi a te US te Federal Specification GGG-P-463c, ā, i muri mai ka whakaurua ki roto i ngā paerewa raupapa ASME B89, e whakarōpū ana i ngā pereti mata mā te Taiwhanga, te Tirotiro, me ngā tohu taputapu i runga i te rerekētanga papatahi mō ia wāhanga horahanga.
JIS (Hapani) — He rite tonu ngā Paerewa Ahumahi Hapanihi ki te nuinga o te hanganga DIN engari ka whakamahia e rātou ō rātou ake ingoa tohu me ngā wā whakamātautau, e whakamahia whānuitia ana e ngā taputapu i kaweake mai i te umanga taputapu mīhini tino tika o Hapani.
GB (Haina) — Kua tata te hononga o ngā paerewa ā-motu o Haina mō ngā pereti mata karāhe me ngā taputapu ine ki ngā tikanga ISO me te DIN i ngā tekau tau e rua kua pahure ake nei, e whakaata ana i te tipu haere o te turanga hangahanga tika o te motu.
BS 817 (Te Hononga o ngā Whenua o Peretānia) me GOST 10905 (Rūhia) — E tautuhi ana ngā mea e rua i ngā whakaritenga ōrite mō te papatahi me te whakaotinga mata, ko te BS 817 i whakamahia i ngā mākete o te Commonwealth, ā, kei te tohua tonu te GOST i roto i ngā hokohoko ahumahi o Rūhia me CIS.
He aha te Hiranga o ngā Rerekētanga i roto i te Mahi
Ko te take mahi ehara i te mea he "pai ake" tētahi paerewa i tētahi atu — engari kāore e taea te huri tika i ngā tohu manawanui i ngā wā katoa. He rite tonu te ariā o tētahi pereti Tohu 0 i raro i te DIN 876 me tētahi pereti Tohu-Taiwhanga i raro i te ASME B89 engari he rerekē ngā tikanga kua whakamatautauria i raro i ngā tikanga me ngā āhuatanga taiao (he rerekē te pāmahana tohutoro 20°C te nuinga, ahakoa he rerekē te manawanui mō te rerekētanga). Ko ngā kaihoko e whakaaro ana he ōrite me te kore e tirotiro i te pūrongo whakamātautau tuturu ka mutu pea ki ngā taputapu e tutuki ana i te tapanga paerewa o tāwāhi engari kāore i te manawanui e hiahiatia ana e tā rātou tukanga.
Ko te Whai Aroturuki te Pātai Tuturu
Haunga te paerewa e tāia ana ki te tiwhikete, ko te pātai nui ko te whai i te tika: ka taea te whai i te whakatikatika mā roto i tētahi whare wānanga ine ine ā-motu? Ka whakatikatikahia e ngā kaihanga rongonui ā rātou taputapu ine — ngā tohu waea, ngā ine whakawhiti laser, ngā taumata hiko — ki ngā tiwhikete i tukuna e ngā whare wānanga whai mana (i Haina, ko ngā whare wānanga ine ine ā-tāone me ā-rohe te nuinga, me te ara hoki ki te Whare Wānanga ine ine ine ā-Motu). Ki te kore taua mekameka, ka rite te pono o te tohu "Reanga 0" ki te taiwhanga nāna i tuku.
Mō ngā miihini e tohu ana i ngā turanga karāhe, i ngā taputapu ine rānei puta noa i ngā kaiwhakarato o te ao, he māmā noa te huarahi mahi: pātaihia te tikanga whakamātautau o te paerewa i whakamahia, tonoa ngā raraunga ine tuturu kaua ko te tapanga tohu anake, ā, whakaū kei te whai tiwhikete whai muri te taputapu whakatikatika. Ko ngā kaihanga e whakangungu ana i ngā kaimahi puta noa i ngā paerewa ā-motu maha - DIN, ASME, JIS, GB, BS, me GOST - he pai ake te tūnga ki te whakaputa i ngā wāhanga e mau ana i raro i te paerewa e hiahiatia ana e te pūnaha kounga a te kiritaki.
