I. Ngā Kaitaraiwa TPR
He rauemi rapa kirihou wera te TPR, he pai te ngāwari me te ātete ki te pakū, he pai ake te ātete ki te pānga me te waikura o ngā wira TPR, ā, he pai ake te urutau ki te whenua taratara. Hei tāpiri, he ngawari te ngākau o ngā wira TPR, he pai te āhua, ā, kāore e ngāwari ki te whakararuraru i te taiao.
Heoi anō, he iti anō hoki ngā ngoikoretanga o ngā wira TPR. Nā te kore e pai te ātete ki te pāmahana teitei, i te nuinga o te wā kei te 70-90 ℃, kāore e pai mō te whakamahi i roto i ētahi taiao pāmahana teitei. Hei tāpiri, he iti te kaha kawe o ngā wira TPR, kāore pea e pai mō ētahi āhuatanga kawe taumaha.
