Letšoao la setifikeiti:
Ex d IIB T4 Gb/Ex tD A21 IP65 T130°C ke setifikeiti sa bokahohle sa tšireletso ea khase le lerōle., moo karolo e neng e le teng pele ho slash (/) e bonts'a boemo ba ho phatloha ha khase, mme karolo ea morao-rao e bonts'a lerōle le phatlohang la ho phatloha.
Ex: Ho Tšoara Lits'ebetso tsa Bopaki, sebopeho se tloaelehileng sa IEC (Khomishene ea machabeng ea elektroniki ea machabeng) litekanyetso tsa bopaki ba ho phatloha.
d: E thibelang mollo mofuta, Ho supa mofuta oa mantlha oa ts'ireletso ea phallo e fetella.
IIB: E emela ts'ireletso ea gas e phatloha.
T4: E bonts'a mocheso Sehlopha.
Gb: E supa sehlahisoa sena se loketse sebaka 1 tshireletso ya ho phatloha.
Bakeng sa ho phatloha ha lerole karolo ho halofo ea morao-rao, Ho lekane ho fihlela sehlopha sa ts'ireletso se phahameng ka ho fetisisa sa ts'ireletso ea lerole 6 e ipapisitse le litekanyetso tsa netefatso ea khase.
tD: E emela mofuta oa ts'ireletso e akaretsang (Ho thibela lerōle la lerole le koahetsoeng).
A21: E bonts'a sebaka se sebetsang, E loketse sebaka 21, Sebaka 22.
IP65: E emela sehlopha sa ts'ireletso.
Ho bohlokoa ho khetha tekanyetso e nepahetseng ea bopaki ba libaka tsa bopaki ba tikoloho.
Ea pele, Ho bohlokoa ho utloisisa mekhahlelo e 'meli ea mantlha, Joalokaha ho hlalositsoe ka tlase:
Mefuta ea Bopaki ba Phatlalatso:
Sehlopha sa I: Lisebelisoa tsa motlakase bakeng sa li-Mines tsa kabelo ea sekhukhu;
Sehlopha sa II: Lisebelisoa tsa motlakase bakeng sa tse ling tsohle qhoma tikoloho ea khase ntle le liqhomane tsa mashala le ka tlas'a lefatše.
Tlelase II e ka aroloa IIA, IIB, le IIC, moo sesebelisoa se tšoaroang ka tlasa maemo a loketseng a lisebelisoa tsa IAA; IIC e ka sebelisoa tlasa maemo a loketseng iia le iib.
Sehlopha sa III: Lisebelisoa tsa motlakase bakeng sa libaka tse phatlohang tsa lerole ho feta liqhomane tsa mashala.
IIIA: Ho fofa ka mokhoa o hlakileng; IIIB: Lerōle le se nang conductive; IIIC: Lerōle le tsamaisang.
Libaka tsa bopaki:
Sebaka 0: Moo likhase tse phallang li lulang li le teng kapa li teng khafetsa; kotsi e sa khaotseng bakeng sa ho feta 1000 Lihora / selemo;
Sebaka 1: Moo e ka chang likhase li ka etsahala nakong ea ts'ebetso e tloaelehileng; Ho hanyetsoa kotsi ka nakoana 10 ho 1000 Lihora / selemo;
Sebaka 2: Moo likhase tse tukang ha li teng hangata le, Haeba li hlaha, li kanna tsa ba tse sa tloaelehang ebile li le khuts'oane; kotsi e kotsi 0.1 ho 10 Lihora / selemo.
Ho bohlokoa ho tseba hore re sebetsana le sehlopha II le III, Sebaka 1, Sebaka 2; Sebaka 21, Sebaka 22.
Ka tloaelo, Ho fihlela IIB e lekane ho likhase, Empa bakeng sa haedrojene, acetylene, le carbon disulfide, boemo bo holimo ba iic bo hlokahala. Bakeng sa polasetiki e phatlohang, fihlella feela khase e lumellanang boemo ba bopaki ba ho phatloha le sehlopha se phahameng ka ho fetisisa sa lerōle.
Ho na le mofuta o kopaneng oa lebokose la kabo la bopaki ba ho phatloha Tekanyetso: Exdeibt4GB.
