lNgā Āhuatanga o te Hua:
1) Kua hangaia tēnei pūnaha nakunaku me te oumu nakunaku whakawera piko hei tinana matua, me te kohikohinga hau putanga me te whakakorenga hau putanga. Ka tutuki i a ia te otinga o te tukanga tukatuka tauira mā te pāwhiri kotahi mai i te ① nakunaku tauira → ② kohikohinga hau putanga → ③ maimoatanga whakakorenga hau putanga → ④ mutu te whakamahana ina oti te nakunaku → ⑤ wehea te ngongo nakunaku mai i te tinana whakamahana ka whakamatao mō te tatari. Ka tutuki i a ia te aunoatanga o te tukanga nakunaku tauira, ka whakapai ake i te taiao mahi, ka whakaiti i te kawenga mahi a ngā kaiwhakahaere.
2) Te kimi i te whata ngongo kei te wāhi tika: Ki te kore te whata ngongo e whakanohoia tika, ka whakaoho te pūnaha, ā, kāore e mahi, ka ārai i te kino o ngā taputapu nā te kore o ngā tauira e whakahaerehia ana, te hē rānei o te whakatakotoranga o ngā ngongo.
3) Te paepae ārai-parahanga me te pūnaha whakaoho: Ka taea e te paepae ārai-parahanga te ārai i te wai waikawa mai i te putanga kohikohi hau putanga mai i te whakapoke i te tēpu whakahaere, i ētahi atu taiao rānei. Ki te kore te paepae e tangohia, ā, ki te whakahaeretia te pūnaha, ka whakaoho, ka mutu te mahi.
4) Ko te oumu nakunaku he taputapu nakunaku me te hurihanga tauira i whakawhanakehia i runga i te kaupapa nakunaku mākū matarohia. E whakamahia ana i roto i te ahuwhenua, te ngahere, te tiaki taiao, te matawhenua, te hinu, te matū, te kai me ētahi atu tari, tae atu ki ngā whare wānanga me ngā whare rangahau mō te maimoatanga nakunaku o ngā tipu, purapura, whāngai kararehe, oneone, konganuku me ētahi atu tauira i mua i te tātari matū. Koinei te hua tino pai mō ngā tātari hauota Kjeldahl.
5) He pai te ōritetanga o te waeine whakamahana karāhe S, he iti hoki te ārai pāmahana, ā, kua hoahoatia kia eke ki te 550℃ te pāmahana.
6) He tere te whakamahana o te waeine whakamahana konumohe L, he roa te ora mahi, ā, he whānui te whakamahinga. Ko te pāmahana i hangaia he 450℃.
7) He mata pa tae 5.6-inihi te rahi o te mata o te pūnaha whakahaere pāmahana, ā, he māmā noa iho te whakahaere.
8) Ka whakamahia e te tāuru hōtaka tātai he tikanga tāuru tere e hangai ana ki te ripanga, he mea arorau, he tere, ā, he iti ake te tūponotanga o ngā hapa.
9) Ka taea te tīpako me te whakatakoto noa i ngā wāhanga 0-40 o ngā hōtaka.
10) Ka taea te whiriwhiri noa i ngā momo whakamahana kotahi-ira me te whakamahana pihi rua.
11) Mā te whakahāngai-ā-ringa P, I, D mohio ka whakarite kia teitei, kia pono, kia pumau hoki te tika o te whakahaere pāmahana.
12) Mā te pūhiko wehe me te mahi whakaara anō ārai-whakaweto ka ārai i ngā tūponotanga kino.
13) He rite rawa ki ngā kōwae tiaki pāmahana-rahi, pēhanga-rahi me te iahiko-rahi.
