IE1 IP54 IP55 Peb Phem Electric Tsav
IP (INGRESS PROTECTION) kev tiv thaiv yog tsim los ntawm IEC (THOOJ ELECTROTECHNICAL COMMISSION), raws li hluav taws xob, tiv thaiv cov khoom txawv teb chaws (nrog rau cov cuab yeej siv, cov ntiv tes tsis yog nyob hauv cov khoom hluav taws xob nyob, kom tsis txhob muaj hluav taws xob. Cov yam ntxwv ntawm kev cuam tshuam thiab kev tiv thaiv ntawm ya raws thiab cuam tshuam. IP tiv thaiv cov chav kawm yog tsim ntawm ob tus lej, thawj tus lej, hais tias hluav taws xob theem kom tiv thaiv intrusion ntawm cov khoom txawv teb chaws, ob cov cuab yeej siv, hais tias anti nphom dej intrusion airtight degree theem, loj dua tus xov tooj ntau dua ntawm kev tiv thaiv.
Tshiab tshiab energy efficiency code (IE) rau hluav taws xob hluav taws xob.
IE1 = txheem zog efficiency (zoo li EFF2)
IE2 = muaj zog ua haujlwm zoo (zoo li EFF1)
IE3 = zoo tshaj plaws thiab muaj txiaj ntsig zoo
