ʻOiai ʻoi aku ka liʻiliʻi, pili kēlā me kēia huahana i ka nānā ʻana i ka hale hana ma mua o ka haʻalele ʻana i ka hale hana, me ka hiʻohiʻona, ka nui, ka mahana hana static a me ka hoʻāʻo ʻana i ka ukana.
I ka wā o ka hoʻāʻo ʻana i ka mahana hana static, ʻo ka mahana ambient hoʻāʻo ʻo (20 ± 5) ℃, a lawe ʻia ka hoʻāʻo i ka ʻauʻau wai.E hoʻohana ʻia ka ʻauʻau wai (ʻoi aku ka maikaʻi o ka wai distilled) no nā ʻōpuʻu aniani me ka mahana hana nominal ʻaʻole i kiʻekiʻe aʻe ma mua o 79 ℃, a e hoʻohana ʻia ka ʻauʻau aila (huahana aila kūpono no ka mahana hana nominal) .Pono ka mahana o ka ʻauʻau wai hoʻāʻo, ʻaʻole e ʻoi aku ka haʻahaʻa o ka wela ma ka wahi hoʻāʻo ma mua o 0.5 ℃, a ʻaʻole e emi ka pololei o ke ana wela ma lalo o ± 0.1 ℃.
E kau i ka la'ana o ka ipu aniani ma ke alo o ka wai auau.ʻAʻole emi ka mamao ma waena o ke kikowaena o ka ipu aniani a me ka pae wai ma mua o (40 ± 5) mm.E hoʻokiʻekiʻe i ka mahana mai ka lumi wela a hiki i (20 ± 2) ℃ haʻahaʻa ma mua o ka wela hana i koho ʻia ma ka helu wela ʻaʻole ʻoi aku ma mua o 20 ℃ / min.ma hope o ka hoʻopaʻa ʻana no 10 mau minuke, e hoʻokiʻekiʻe i ka mahana ma kahi o 0.4 ℃ / min ~ 0.6 ℃ / min a hiki i ka haki ʻana o nā laʻana a pau.E hoʻopaʻa i ka mahana hana o kēlā me kēia laʻana, E hoʻoholo inā ʻoi aku ka nui o nā hopena hōʻike i ka pae wela aʻe:
