Tuatahi, he rerekē ngā whakamāramatanga e rua:
1, anga ātete-pahū "d": he momo taputapu hiko ātete-pahū, ka taea e te anga te tu atu i tetahi hononga, i tetahi āputa hanganga rānei i roto i te anga ki roto i te anga o te ranunga pahū i roto i te pahū me te kore e pakaru, ā, e kore e puta he hau, he kohu rānei i hangaia e te mura o te taiao hau pahū. (I tautuhia kia rite ki te GB3836-2010) Ngā wāhanga o roto mō ngā wāhanga noa.
2, momo haumaru kua whakanuia "e": he momo omomo ātete-pahūtanga taputapu hiko, arā, me mahi ētahi atu mahi a ngā taputapu hiko hei whakapai ake i tōna taumata haumaru, hei ārai i te tūponotanga o ngā pāmahana kino, ngā pewa me ngā mura e puta mai ana i te mahi noa, i raro rānei i ngā āhuatanga rerekē kua tohua.
He whakarāpopototanga noa iho: kāore tōna roto e whakaputa i ngā pāmahana kino, i ngā pewa me te tūponotanga o ngā mura, engari hei whakapai ake i tōna taumata haumaru, pērā i te whakapai ake i te taumata tiaki. Me whai tohu Ex ngā wāhanga o roto (ngā wāhanga ātete-pahū).
Tuarua, he rerekē te momo hanganga anga o ēnei e rua:
1, momo ātete-pahū "d" nā te mea me tu atu ki te pēhanga pahū o roto, nō reira me hangaia kia tukuna te urunga hiko (he māmā noa iho, ko te mata o te flange), ko te matotoru o te pakitara toharite o te anga he matotoru ake i te momo haumaru kua whakanuia.
2, he momo haumaru "e" kua piki ake nā te mea kāore te roto e whakaputa i ngā pāmahana morearea, ngā pewa me te tūponotanga o ngā mura, nō reira kāore he flange.
Tuatoru, ko tētahi atu:
1, ko te momo ātete-pahū "d" me te momo haumaru-tūturu "i" anake kei a ia te Ⅱ A, Ⅱ B, Ⅱ C; ā, ko te momo haumaru nui ake kāore i wehea ki te Ⅱ A, Ⅱ B, Ⅱ C.
2, hei tauira o te rūma waea, me whakamahi te taputapu whakataki momo "d" ātete-pahūtanga hei whakataki momo "d" (ātete-pahūtanga), kia roa ake te haumaru o te mowhiti hiri ina whakaritea ki te whakanui ake i te haumaru o te mowhiti hiri, kia roa ake te haumaru o te taputapu ina haere tonu te whakataki ki te whakapai ake i te taumata haumaru o te raina.
3, me whakamātautau waipēhi te anga "d" ātete-pahū (Ⅱ B 1.5 MPa / 10 hēkona o te pēhanga wai, Ⅱ C 2.0 MPa / 10 hēkona o te pēhanga wai), ā, kāore e hiahiatia he whakanui ake i te haumaru.
4, me whakamātautau pānga te anga "d" ātete-pahū (kia tu atu ki te taumaha o te mea whakamātautau 1kg mai i te teitei o te 0.7m i te whakamātautau pānga poutū), kāore te anga haumaru nui ake e whakamātautau pānga.
