Tono

Ngā Kawe Mata Ārai (AFC), ngā Utaina Wāhanga Kurupae (BSL), ngā mīhini whakatere rori, ngā parau waro, me ētahi atu.

Hei whenua hanga waro Nama 1, kua kitea e Haina te tono nui mō ngā mekameka keri porowhita, ā, nā reira kua akiakihia te kaha hanga mekameka hono maitai porowhita o Haina i runga i te rahinga me te kounga. Ko te wheketere mekameka a SCIC, me tana hītori hanga mekameka hono maitai 30 tau te roa, kua uru katoa ki te tuku waro ki Haina; kua whakaaetia ā mātou mekameka hono porowhita, ā, kua whakamahia e ngā kamupene waro me te keri matua katoa puta noa i Haina.

Ka whakapūmautia te kounga o tā mātou mekameka hononga maitai porowhita i roto i ia taahiraa o te hanga mekameka, mai i ngā pae maitai koranu pakari ki te hanga hononga tika mā te karetao, mai i te whakarewa uira rorohiko ki te maimoatanga wera tinei me te whakamahana kua hoahoatia pai (ka hua ake te kaha me te pakeke o te mata e hiahiatia ana), mai i te whakamātautau whakamātautau ki ngā whakamātautau miihini hei manatoko i te kounga o te mata me roto.

Ko te mekameka hono porowhita SCIC e hangaia ana kia rite ki te paerewa Haina GB/T-12718 me ngā Whakaritenga Hangarau wheketere, tae atu ki ngā paerewa DIN 22252, GOST 25996 rānei me ngā whakaritenga a te kiritaki.

E whakamahia ana te mekameka hono porowhita SCIC mō ngā Kawe Mata Ārai (AFC), ngā Utaina Wāhanga Kurupae (BSL), ngā mīhini pane rori, ngā parau waro me ētahi atu taputapu e hiahia ana ki tēnei momo mekameka.

Ka heke te āhua o te mekameka i ngā paninga ārai-waikura (hei tauira, te whakawerawera wera), nō reira ko te paninga o ngā paninga ārai-waikura me whai i te whakaaetanga ota i waenga i te kaihoko me te SCIC.
