Kei te tipu haere tonu te mākete Pākehā mō ngā ngongo maitai tino tika, ā, kei te tere haere te whanaketanga o ngā kaupapa here kawemai a te EU me te Tikanga Whakatikatika Rohe Waro (CBAM). Kei raro nei tā mātou whakahōutanga mākete mō ngā ngongo maitai matao kua whakarewaina EN 10305-3, hei tohutoro mā ngā kiritaki Pākehā.
1. Tirohanga Whānui o te Mākete me ngā Whakamahinga
Ko te EN 10305-3 he paerewa matua o Ūropi mō ngā ngongo maitai tino tika. Ko te putanga hou ko te EN 10305-3:2023. E pā ana tēnei paerewa ki ngā ngongo maitai porowhita, tapawhā me te tapawhā hāngai kua whakarewaina, he whānui o waho ≤ 193.7mm, e tohuhia ana e ngā āheinga ā-ahu tino pakari me te taratara mata mōrahi kua tohua.
Ngā Āhuatanga Matua:
Te manawanui OD he pūmau tae atu ki te ±0.12mm (tae atu ki te porowhita-kore)
Te manawanui matotoru o te pakitara: ±0.15mm mō te T≤1.5mm; ±10% ±0.35mm rānei (ko te mea iti ake) mō te T>1.5mm
Te taratara o te mata Ra ≤ 4μm
Te Tika ≤ 0.002 × L
Ngā tono noa:
Ngā Wāhanga Waka: Ngā pou urungi, ngā toki taraiwa, ngā pūnaha pēke hau, ngā wāhanga anga
Hangarau Mīhini: Ngā rango waipēhi, ngā roera kawe, ngā wāhanga tino tika
Te Hanga Taonga: Ngā kōtaha karu, ngā wāhanga hanganga o ngā taonga tari
Ngā Pūnaha HVAC: Ngā paipa whakamahana matua, ngā pūnaha whakamahana kati kōtuhi
Mīhini Ahuwhenua: Ngā wāhanga taputapu ahuwhenua
Ngā Tohu Rauemi me ngā Tikanga Tukunga: Ka hipokina e te paerewa ngā tohu maitai maha mai i te E155 ki te E700. Kei te wātea ngā tohu kaha teitei ake mō ngā tono uaua. Kei roto i ngā tikanga tukunga:
+CR1 (Rahi makariri, ka taea te whakamahana)
+CR2 (Rahi makariri, kāore i te hangaia mō te whakamahana)
+A (Kua whakamahanahia i roto i te hau whakahaeretia)
+N (Kua whakapūmautia i roto i te āhuarangi whakahaeretia)
2. Ngā Kaupapa Here Kawemai a Ūropi me te CBAM
Kei te whakahou te EU i te mekameka tuku maitai mā roto i ngā kaupapa here maha:
CBAM (Tikanga Whakatikatika Rohe Waro): I uru ki te wāhanga whakatinanatanga nui i te tau 2026. Me hoko e ngā kawemai ngā tiwhikete CBAM mō ngā tukunga kua whakauruhia
Ngā Mahi Tiaki: Kei te whakawhāiti tonu ngā herenga kawemai maitai
Te Auahatanga Waro-Iti: Kei te kaha haere ngā whakaritenga a te EU mō te tapuwae waro maitai kawemai
3. Tātaritanga Whenua o te Kaiwhakarato
Te Tūnga Whakaputa i Haina:
Kei Tianjin, Hebei, Jiangsu me ētahi atu rohe te kaha whakaputa EN 10305-3.
Ko te whakaritenga hangarau matua ko te tukanga whakatakotoranga matao – kāore e taea e ngā mira paipa whakarewa noa me te kore tēnei tukanga te whakatutuki i ngā whakaritenga paerewa mō te tika.

He aha i kiia ai te EN 10305-3 he "tika" kaua ki ngā ngongo hanganga paerewa? Ko ngā rerekētanga matua ko:
Ngā Pūwāhi Whakahaere Whakaputa Matua:
Me tino patu te rauemi mata i te maitai kia ōrite te hanganga
Me rite te whakarewa o waho ki te mata o te konganuku matua.
Me whakamahana ngā āhuatanga +A/+N i roto i te hau whakahaeretia
Ka ārai te āhua +CR2 i tētahi maimoatanga wera i muri mai
