Ngā Koki ASTM, e mōhiotia ana ko te maitai koki, he mea nui ki te whakarato tautoko hanganga me te pumau mō ngā taonga mai i ngā pourewa whakawhitiwhiti kōrero me te hiko ki ngā awheawhe me ngā whare maitai, ā, mā te hangarau tika i muri i te pae koki gi ka taea e rātou te tu atu i ngā kawenga taumaha.
Pae koki maitai ASTME rua ngā momo e wātea ana, he rite, he kore taurite, i runga i te hohonutanga o ngā waewae. Ko ngā koki kore taurite, e mōhiotia ana ko te maitai āhua-L, ka whakamahia i te nuinga o te wā ina roa ake tetahi waewae o te koki i tetahi atu, ko ngā koki ōrite ka whakamahia ina rite te roa o ngā waewae e rua, ā, he pai ngā koki ASTM mō te whānuitanga o ngā tono hanganga.
Haunga ngā whakamahinga ahumahi me te hangarau,Pae koki ASTM kua whakakikoruatiaka kitea i roto i ngā taonga o ia rā. Mai i ngā whata ahumahi ki ngā tēpu kawhe tawhito, e whakaatu ana tēnei i te ngāwari me te whānui o te whakamahinga o ngā koki ASTM ki ngā āhuatanga katoa o ō tātou oranga.
Mā te tohu ASTM ka tutuki ngā koki i ngā paerewa pakari i whakatakotoria e te American Society for Testing and Materials, arā, ka hangaia, ka whakamatautauria hoki ki ngā āhuatanga miihini motuhake, tae atu ki te kaha tuku, te kaha kume, me te roa.
Ko te hangarau tika kei muriKoki ASTME whakaatu ana tēnei he mea nui te kaha ki te whakaputa maitai koki me ngā inenga tika me ngā āhuatanga miihini hei whakarite i te hanganga tika o ngā whare, ngā pourewa me ētahi atu kaupapa hangarau. Mā tēnei hangarau tika ka taea hoki te whakamahi pai i ngā rauemi, te whakaiti i te para, me te arotau i te tukanga hanga katoa.
