(3) te whakamahi i te mekameka hononga porowhita hei hiki
a. me rite, me iti iho rānei te taumaha o te kawenga i te WLL mōrahi o te whitiki mekameka hiki.
b. ina whakamahia ana te mekameka whiri waewae-rua, waewae-maha rānei, ko te nui ake o te koki o ngā waewae whiri, ko te iti ake o te kawenga ka taea te hiki; me iti iho te koki o ngā waewae i te 120° ahakoa pēhea (arā, ko te koki o te waewae mekameka me te koki ārahi poutū me iti iho i te 60°).
c. ina hikihia ana te here here, me iti iho te kawenga i te 80% WLL.
d. Me tika te mekameka hiki, kaua e takahuri, e here, e piko rānei. Me karo i ngā mea taumaha e hurihuri ana i runga i te mekameka.
(1) te tirotiro i ia rā
a. Kaitirotiro, auau me ngā tuhinga
Me tirotiro tonu te kaiwhakahaere, te kaimahi rānei kua tohua i te mekameka hiki i ia rā mahi, ā, me tuhi he tuhinga mō te "tirohia te tauira tirotiro o ia rā o te whitiki" (tirohia te Tāpiritanga) ki te wāhi mahi, hei tohu ka taea te whakamahi i te whitiki i ngā wā katoa.
b. Tirotiro ā-kanohi
Tirohia te āhua mō ngā tohu o te pakaru nui, te rerekētanga o te āhua, te kino rānei o waho. Mēnā ka kitea he hapa i roto i te tirotiro, whakaūtia mēnā ka taea te whakamahi anō kia rite ki te tikanga tirotiro noa.
(2) Te tirotiro ā-wā
a. Kaitirotiro, auau me ngā tuhinga
Me tirotiro whānui te mekameka e te kaimahi kua tohua, e ai ki ngā tohu hapa i puta i te tirotiro auau, ā, me tuhi tuhinga hei aromatawai mēnā ka taea tonu te whakamahi i te mekameka.
b. Ngā wāhi tirotiro
i) Mēnā he mārama ngā tohu o waho pērā i te tohu mekameka hiki me te kawenga mahi mutunga;
ii) Kua hē te āhua, kua tapahia, kua pakaru hoki ngā hononga pito o runga me raro (te hononga matua, te hononga waenga, ngā hononga me ngā matau) o te mekameka hiki, ā, kua hipa ake i ngā whakaritenga paerewa, ā, kāore e taea te whakamahi;
iii) Te whakarerekētanga o te hononga mekameka: kua miro, kua piko, kua roa te hononga mekameka, ā, kāore e taea te whakamahi ina neke atu i ngā whakaritenga paerewa;
iv) Te pakaru o te hononga: kāore e taea te whakamahi i te kohao, te kohao, te haehae me te pakaru o te hononga i waho o te wāhanga tika ina neke atu i ngā whakaritenga paerewa;
v) Te whakarerekētanga o te matau: ko te whakarerekētanga "tuwheratanga" me te whakapōturitanga o te tuwhera o te matau ka nui atu i ngā whakaritenga paerewa, ā, kāore e taea te whakamahi;
vi) Ngā pakaru: kāore e taea te whakamahi i ngā pakaru i whakamātauria mā te tirohanga ā-kanohi, mā te NDT rānei.
a. te whakarerekētanga:
te roa o waho te roa>3%
te roa o roto>5%
b. te mau:
kaua te diameter o te hononga whakawhiti i muri i te mau e iti iho i te 10% (arā, te diameter < 90% o te ingoa)
c. ngā pakaru:
Kāore e whakaaetia he pakaru ki te mata o te mekameka hononga mā te tirotiro ā-kanohi, mā te tirotiro taputapu rānei.
d. piko, whakapōturi rānei:
Kāore e whakaaetia te piko, te hē rānei e kitea ana, te waikura nui, te tāpiritanga rānei e kore e taea te tango ki te hononga mekameka.
(2) matau
a. Te whakatuwheratanga o te matau: kaua te rahi o te whakatuwheratanga o te matau e neke ake i te 10% o te uara ingoa.
b. Te pakaru o te wāhanga taumaha (morearea): kaua te matotoru o te wāhanga i te wāhi pakaru e whakaitihia kia neke atu i te 5%
c. Te whakarerekētanga o te takai: kaua te whakarerekētanga o te takai o te tinana matau e neke ake i te 5%.
d. Ngā pakaru: kāore e whakaaetia kia pakaru te mata o te matau katoa mā te tirotiro ā-kanohi, mā te tirotiro taputapu rānei.
e. Ngā nika me ngā kōhao: ka taea te whakatika mā te huri, te whakakōhao rānei. Me neke pai te mata kua whakatikahia me ngā mata e tata ana, me te kore e whakarerekē ohorere i te wāhanga. Kaua te matotoru o te wāhanga kua orohia e whakaitihia neke atu i te 5%.
(3) hononga matua
a. Whakapōturi: kaua te whakapōturi o te hononga matua katoa e neke ake i te 5%.
b. Te Pakaru: kaua te pakaru o te mata hononga matua e neke ake i te 10% o te diameter taketake
c. Ngā pakaru: kāore e whakaaetia ngā pakaru ki te mata katoa o te hononga matua mā te tirotiro ā-kanohi, mā te tirotiro taputapu rānei.
(4) ngā mekameka me ētahi atu taputapu
a. Te whakatuwheratanga: ko te rahi o te whakatuwheratanga o te mekameka he nui ake i te 10% o te uara taketake.
b. Te Pakaru: ko te diameter o te pine, te rakau pine rānei, kua pakaru neke atu i te 10% o te diameter taketake; ko te pakaru o te wāhanga taumaha (mōrearea) neke atu i te 5%
c. Ngatata: kāore e whakaaetia kia ngatata te mata katoa o te taputapu mā te tirotiro ā-kanohi, mā te tirotiro taputapu rānei.
(1) Ngā hononga mekameka noa
