1. Whakataki Whānui

Ko te EN 10305-5 he wāhanga motuhake i roto i te raupapa paerewa ngongo maitai tino tika o Ūropi. Ko tōna taitara katoa ko "Ngā ngongo maitai tino tika"—Wāhanga 5: Ngā tikanga tuku hangarau mō ngā ngongo maitai tapawhā me te tapawhā tika kua oti te whakamatao." Nā te Komiti Paerewa o Ūropi (CEN) i whakawhanake te paerewa, ā, ko tētahi o ngā paearu hangarau matua mō te whakaputa me te whakaae ki ngā ngongo maitai āhua tika puta noa i te EU.

 E pā ana tēnei paerewa ki ngā ngongo tapawhā me ngā ngongo tapawhā kua oti te whakamatao, ko te matotoru pakitara mōrahi he 6mm, ā, ko te diameter waho iti rawa he 4mm. Ko te tino tika o ēnei hua, ko te kounga mata teitei, me ngā āhuatanga miihini ōrite, e whakanoho ana i a rātou hei hua ngongo maitai tāpiri uara nui.

 2. Ngā Whakaritenga Hangarau Matua

2.1 Ngā Wāhanga Rino

 E rua ngā momo maitai matua e tohua ana e te paerewa:

 E235: Ko te momo taketake e tuku ana i te mahi whānui taurite, te kaha whakarewa pai, me te kaha hanga matao tino pai. Koinei te momo e whakamahia whānuitia ana i te mākete.

 E355: He momo kaha teitei me ngā tohu kaha kua whakapaitia me te pakari pānga ki te E235, e tika ana mō ngā tono pikaunga taumaha ake.

 2.2 Te Hanganga Matū (E235 hei Tohutoro)

 Huānga C Si Mn P S

Ihirangi (%) 0.17-0.22 0.10-0.35 0.40-0.80 ≤0.035 ≤0.035

2.3 Ngā Āhuatanga Ā-ringa (E235 hei Tohutoro)

 Kaha Kume: 440-540 MPa

 Te Kaha o te Hua:≥290 MPa

 Te Toronga Ōrau:≥12%

 2.4 Ngā Tikanga Tukunga

 Ka taea e te paerewa te whakamahi i ngā tikanga tuku maha, i runga i te whakaaetanga i waenga i te kaiwhakarato me te kaihoko:

 BK (Pakeke kua oti te whakamatao): Ka tukuna mai me te kore he maimoatanga wera, ka mau tonu te āhua pakeke i muri i te mahi matao

 BKW (Mahia mārire ki te makariri): Mahia mārire ki te makariri me te mau tonu o te āhua hanga

 GBK (Kua whakawerahia): Kua whakawerahia i muri i te mahi matao

 NBK (Kua Whakaritea): I tukuna i roto i te āhua kua whakaritea

 3. Ngā Mākete Taupānga

Ko ngā ngongo maitai EN 10305-5 e whakamahia ana i roto i ngā mahi hanga tino tika. Ko ngā whakamahinga noa ko:

 Ngā Pūnaha Tuku Waipēhi: Ngā ara iahiko hinu waipēhi i roto i ngā mīhini hanga me ngā taputapu mīhini, e hiahia ana ki ngā ine tika me ngā mata maeneene o roto hei whakarite i te pai o te tuku wai.

 Ngā Pūnaha Whakahaere Hauā: ​​Ko ngā raina tuku hau kōpeke me ngā whakaritenga tino pakari mō te tika o te hiri.

 Te Hanganga Wāhanga Motuka: Ngā raina werohanga wahie pēhanga teitei me ngā paipa pūnaha urungi hiko—ngā wāhanga haumaru matua e rua.

 Mīhini Whānui: Whakamahia hei papa kore mō ngā ringaringa pou tika, ngā ringaringa ārahi, me ngā tautoko hanganga mō ngā mahi mīhini o muri mai.

 Te Whakaurunga Taputapu Ahumahi: Ngā ringaringa pūoko, ngā ngongo taputapu, me ngā tono tika rite.

 4. Ngā Ahumahi e Pā Ana

Ko ngā hua i raro i te EN 10305-5 e mahi ana i ngā rāngai ahumahi e whai ake nei:

Te Hanga Waka Aunoa me te Waka Arumoni

Ngā Mīhini Hanga me ngā Taputapu Ahuwhenua

Te Hanganga Waenga Waipēhi me te Haumātika

Ngā Taputapu Whānui me te Mīhini Tika

Aunoatanga Ahumahi me te Whakaurunga Pūnaha Whakahaere

5. Te Tūnga me te Uara o te Mākete

Kāore te EN 10305-5 e taka ki roto i te kāwai o ngā ngongo hanganga whānui. Engari, e aro ana ki te mākete ngongo maitai motuhake tino tika, tino pono, me te tino tāpiri uara. Ko ōna uara matua ko:

Te whakarato i ngā manawanui inenga me ngā tohu mahi ka taea te matapae me te manatoko ki ngā kiritaki

Te whakaiti i ngā para rauemi me ngā utu mahi anō mō ​​ngā kiritaki o muri i te wā e mahi ana i ngā mahi miihini me te huihuinga

Te whakarite kia pumau te mahi a ngā taputapu whakamahinga mutunga mō te wā roa i raro i ngā tikanga mahi pēhanga teitei me te huringa teitei

Mō ngā kaihokohoko ngongo rino Hainamana, ko te EN 10305-5 tētahi o ngā paerewa taumata-whakaurunga noa mō te uru atu ki te mekameka tuku hanga tino tika o Ūropi. Ko te kaha kua whakaaturia ki te tuku hua e tutuki ana i tēnei paerewa he tohu nui mō te whiwhi whakamihi mai i ngā kiritaki Ūropi waenga-ki-teitei i roto i ngā wāhanga motuka, ngā pūnaha waipēhi, me ngā rāngai e pā ana.
