2021-05-17

  Nui nā ʻano maʻamau a puni ka honua a i kekahi manawa hiki i nā maʻamau like ʻole ke huikau i ka poʻe mai nā ʻāina like ʻole e koho i nā mea e pono ai lākou.


  No ka ʻike pehea e hoʻololi ai i ka maʻamau mai nā ʻāina like ʻole, pono mākou e ʻike mua i ka wehewehe ʻana o lākou.

1. NEMA

  Ua hoʻokumu ʻia ka National Electrical Manufacturers Association (NEMA) i ka hāʻule o 1926 ma muli o ka hui ʻana o ka American Electric Power Club a me ka American Electrical Supplier Manufacturers Association. ʻO kekahi o nā hana nui a NEMA ʻo ia ka hāʻawi ʻana i kahi ʻaha kūkā no ka hoʻomaʻamaʻa ʻana i nā mea uila e hōʻoia i ka palekana, kūpono a me ka hoʻohālikelike ʻana o nā mea uila.


  Ua hāʻawi nui ʻo NEMA i ka ʻoihana uila ma ke komo ʻana i ka hoʻokumu ʻana i nā kulekele aupuni a ma ke ʻano he kikowaena kikowaena no ka hōʻiliʻili, hōʻuluʻulu ʻana, a me ka nānā ʻana i nā helu makeke/ʻikepili waiwai.


  Aia ke keʻena nui o NEMA ma Rosslyn, Virginia, USA i kēia manawa ma kahi o 400 mau lālā, me nā mea hana nui, waena a me nā mea liʻiliʻi o nā lako hana mana, nā mea hoʻoili a me ka hāʻawi ʻana, nā lako mana mana a me nā huahana terminal uila. ʻO ka huina kūʻai makahiki o nā huahana i hana ʻia e nā lālā NEMA ma kahi o US $100 biliona.

2. IEC

  Ua hoʻokumu ʻia ka International Electro Technical Commission (IEC) ma 1906. ʻO ia ka hui mua loa o ka honua non-governmental electro technical standardization a me kahi hui kūkākūkā Class A o ka United Nations Economic and Social Council (ECOSOC).

3. DIN

  Ke Keʻena Kelemānia no ka Hoʻohālikelike. Ka inoa Kelemānia: Deutsches Institut für Normung eV Ka pōkole German: DIN. ʻO ka hui aupuni ʻole nui loa o Kelemania no ka hoʻoponopono ʻana i ka pono o ka lehulehu me ka hōʻike nui ʻana. Hoʻokumu ʻia ma 1917. Aia ke keʻena nui ma ke kapikala ʻo Berlin. Ma o ka hui pū ʻana o nā ʻaoʻao kūpono, no ka pono o ka lehulehu, ʻo ka hoʻokumu ʻana a me ka hoʻolaha ʻana i nā kūlana Kelemania a me nā hopena hana standardization a me ka hoʻolaha ʻana i kā lākou noi e kōkua i ka rationalization, hōʻoia maikaʻi, palekana a me ka palekana o ka waiwai, ʻenehana, ʻepekema. , hooponopono a me na hana lehulehu.

4. GB

  ʻO ka National Standard of the People's Republic of China, i kapa ʻia ʻo National Standard, he code maʻamau aupuni e komo pū ana me kahi ʻōnaehana coding. Hōʻike ʻia ia e nā hui lālā o ka People's Republic of China i ka International Organization for Standardization (ISO) a me ka International Electro technical Commission (a i ʻole International Electro technical Association, IEC): National Standardization Issued by the Management Committee. Nā kūlana i hoʻopuka ʻia i ka makahiki 1994 a ma mua o ka hoʻohana ʻana i ʻelua huahelu e hōʻike i ka makahiki. Ua hoʻololi ʻia nā maʻamau i hoʻokuʻu ʻia i ka makahiki 1995, ka makahiki ma hope o ka helu maʻamau, i 4 mau helu e hōʻike ai. Hoʻopili ʻia nā maʻamau mandatory me "GB". Kuhi ʻia ka maʻamau i ʻōlelo ʻia me "GB/T".

5. JIS

  ʻO Japanese Industrial Standards (JIS, Japanese Industrial Standards) nā kūlana koʻikoʻi a mana i waena o nā kūlana aupuni Iapana. Hoʻomohala ʻia e ke Kōmike Kūʻai Kūʻai Kūʻai Kepanī (JISC).


  Nā code e pili ana ma JIS: A-Civil Engineering and Construction; B-Mekini Nui; C Uila a me Electronic; D-Kaʻa; E-Kaaahi; M-moku; G-Steel; H-Non-ferrous Metal; K-Kemika; L- Fiber; M-mine; P-pulp, pepa; ʻōnaehana Q-hoʻokele; ʻoihana kapuahi R; S-pono i kela la i keia la; ʻO nā lako palekana T-lāʻau; W-lele; X-ʻike hana; Z-ē aʻe.


Hiki i ka pakuhi ma lalo ke hōʻike iā ʻoe pehea e hoʻololi ai i kēlā me kēia plastics i kekahi i kekahi FR4 pepa, 3240 Epoxy Resin Pepa, 3026 Phenolic pulupulu lole Laminated Pepa, papa pepa phenolic a laila.
