Mekameka Keri - mekameka hononga papatahi

I whakaurua tuatahitia te mekameka hononga momo papatahi ki te umanga keri e te kamupene hanga mekameka Tiamana i te tau 1985. He hononga porowhita (DIN 22252) te mekameka hononga papatahi, engari ko ia hononga tuarua (te hononga poutū) he hononga papatahi, ā, he papatahi ngā taha tika, e ai ki te DIN 22255. Nā te whānui o waho o te hononga papatahi (poutū) i te hononga porowhita (whakapae), nō reira, he iti iho te teitei katoa o te mekameka hononga papatahi me te rahi o te hononga papatahi.

He mea hanga ngā hononga papatahi SCIC, he mea hanga anō hoki ki ngā hononga porowhita.

I runga i ngā āhuatanga, he nui ake te horahanga whakawhiti tika papatahi i te horahanga o te hononga porowhita. Ina oti te mekameka hononga papatahi katoa te whakamahana me te tirotiro me te whakamātautau whakamutunga, ka tino whakamanahia ngā āhuatanga hangarau o ngā hononga papatahi e ai ki te rahi me te momo mekameka kua tohua.

Tawhā mekameka

I hangaia te mekameka hononga papatahi SCIC kia rite ki te paerewa Haina MT/T-929 me ngā Whakaritenga Hangarau o te wheketere, tae atu ki te DIN 22255, ki ngā whakaritenga rānei a te kiritaki (me whakaae motuhake tēnei).

E whakamahia ana te mekameka hononga papatahi SCIC mō ngā Kawe Mata Ārai (AFC), ngā Utaina Wāhanga Kurupae (BSL), ngā mīhini pane rori 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.
