Muyezo wa ASTM A333 umaphimba chitoliro cha kaboni ndi zitsulo zotayidwa pakhoma zomwe zimagwiritsidwa ntchito kutentha kochepa. Chitoliro cha ASTM A333 chotayidwa chiyenera kupangidwa ndi njira yosatayidwa kapena yotayidwa popanda kuwonjezera chitsulo chodzaza pa ntchito yotayidwa. Mapaipi onse osatayidwa komanso otayidwa ayenera kukonzedwa kuti azitha kuwongolera kapangidwe kake. Mayeso okakamiza, mayeso okhudza mphamvu, mayeso a hydrostatic, ndi mayeso amagetsi osawononga ayenera kupangidwa motsatira zofunikira zomwe zafotokozedwa. Kukula kwina kwa zinthu sikungakhalepo malinga ndi izi chifukwa makulidwe a makoma olemera amakhudza kwambiri mphamvu zomwe zimakhudzidwa ndi kutentha kochepa.
Kupanga mapaipi achitsulo a ASTM A333 kumaphatikizapo zolakwika zingapo zooneka pamwamba kuti zitsimikizire kuti zapangidwa bwino. Chitoliro chachitsulo cha ASTM A333 chiyenera kukanidwa ngati zolakwika pamwamba sizikulandiridwa, koma zikuwonekera pamalo akuluakulu kuposa zomwe zimaonedwa ngati zomaliza zogwirira ntchito. Chitoliro chomalizidwacho chiyenera kukhala chowongoka bwino.
