Mipope yachitsulo yosasunthika imapangidwa mosiyanasiyana kuti ikwaniritse zofunikira zosiyanasiyana zogwiritsira ntchito komanso zofunikira zamakampani. Nayi miyezo yomwe nthawi zambiri imatchulidwa pamapaipi opanda zitsulo:
ASTM (American Society for Testing and Equipment):
ASTM A53: Kukhazikika kwa chitoliro, chitsulo, chakuda ndi choviikidwa, chokutidwa ndi zinki, chowotcherera, komanso chopanda msoko.
ASTM A106: Mafotokozedwe okhazikika a chitoliro chachitsulo chosasunthika cha carbon pa ntchito yotentha kwambiri.
API (American Petroleum Institute):
API 5L: Tsatanetsatane wa chitoliro cha mzere, chomwe chimagwiritsidwa ntchito poyendetsa mafuta ndi gasi.
