Ngā paerewa paheke o ngā hu haumaru (hu haumaru mahi)
E ai ki te kaupapa a cen/tc161, ka whakaae tahi ngā taputapu tiaki whaiaro, ngā taputapu haumaru (iso/tc94) me SC3: ko te paerewa o Hu Haumaru Mō ngā taputapu tiaki whaiaro, EN ISO 20345:2004, ka whakamahia e te tikanga whakamātautau ārai-paheke te paerewa ISO 13287:2006, ā, ka whakarerekētia te tau paerewa taketake ki EN ISO 20345:2004/a1:2007. Ko te āhua whakamātautau paheke i roto i tēnei paerewa ko te whakamātautau paheke i waenga i te atanga o te otinga konutai dodecyl sulfate me te atanga glycerol o te pereti maitai. Ka taea te tohu i te mea tuatahi hei SRA ina paahitia te whakamātautau, ā, ka taea te tohu i te mea tuarua mā te whakamātautau. Mō te SRB, ka taea te tohu i ngā whakamātautau e rua hei Src.
E rua ngā whakamātautau taiwhanga matua e whakahaua ana e te paerewa hou hei aromatawai i te mahi a ngā hu. Ko te tuatahi e whakatauira ana i ngā taiao iti-waku mā te whakamahi i te otinga konutai dodecyl sulfate—he matū horoi noa e kitea ana i roto i ngā kaihoroi ahumahi—hei tohu i ngā mata maeneene, kua poke i te hopi. Ko ngā hu e paahitia ana i tēnei whakamātautau ka whiwhi i te whakarōpūtanga SRA. Ko te tuarua o ngā whakamātautau ka whakamahi i te pereti maitai kua pania ki te glycerol hei tārua i ngā tūponotanga pēnei i te hinu, te hinu rānei e maringi ana; ko ngā tauira e wikitoria ana i tēnei wero ka whiwhi i te tiwhikete SRB. Ko ngā hua e tutuki ana i ngā aromatawai pakari e rua ka whiwhi i te whakatauranga SRC teitei rawa atu, e tohu ana i te ātete paheke whānui puta noa i ngā āhuatanga tūponotanga rerekē.
Ka arohia e tēnei paerewa tētahi āputa nui i roto i te haumaru mahi. Ko ngā aituā paheke me te hinga tonu te tino take o ngā whara ahumahi, inā koa i roto i ngā rāngai pēnei i te hanga, te hangahanga, me te tukatuka kai e pāngia pinepine ana ngā mata e ngā wai, e ngā hinu whakahinuhinu rānei. Mā te tono whakamātautau whai take, ka taea te tāruarua i raro i ngā āhuatanga whakahaere, ka whakarite te anga hou Hu Haumaru ka whakarato i te kaha pupuri ina whakatere ngā kaimahi i ngā taiao morearea nui. Me hoahoa e ngā kaihanga ngā takahanga o waho e mau tonu ai te mau ki ngā mata mākū kua tukatukahia ki ngā matū me ngā papa matotoru, hinuhinu hoki—he whanaketanga hangarau nui tēnei mai i ngā aromatawai kotahi-āhua o mua.
Mā te pūnaha tapanga SRA/SRB/SRC ka taea e ngā kaitukumahi te whiriwhiri i ngā hu e hāngai ana ki ngā tūponotanga motuhake o te wāhi mahi, ā, ka mārama ake te tirohanga a ngā kaimahi ki ngā āheinga tiaki. I te mea ka whakamahia e ngā mekameka tuku o te ao ēnei paerewa kotahi, e tūmanakohia ana ka kaha ake te rite o te ao ki te whakatutuki i ngā whakaritenga haumaru, ka whakatairanga i ngā mahi ahumahi haumaru puta noa i te ao.
