Rupa-rupa alat-alat listrik tahan ledakan merlukeun standar panyalindungan casing anu béda. Standar ieu, katelah sasmita panyalindungan, denote the casing’s capability to block external objects from penetrating its interior and to provide resistance against water ingress. Nurutkeun kana “Derajat panyalindungan disadiakeun ku Enclosures (Kode IP)” (GB4208), a casing’s protection grade is denoted by the IP code. This code comprises the initials IP (International Protection), followed by two numerals and sometimes optional additional letters (which are occasionally omitted).
| Jumlah | Rentang panyalindungan | Jelaskeun |
|---|---|---|
| 0 | Teu ditangtayungan | Taya panyalindungan husus ngalawan cai atawa Uap |
| 1 | Nyegah titik-titik cai tina soak | Titisan cai ragrag vertikal (kayaning condensate) moal ngabalukarkeun karuksakan kana alat-alat listrik |
| 2 | Nalika dimiringkeun di 15 darajat, titik-titik cai masih bisa dicegah tina soaking di | Nalika alat didengdekkeun vertikal ka 15 darajat, cai netes moal ngabalukarkeun karuksakan kana alat |
| 3 | Nyegah cai disemprot tina soaking di | Nyegah hujan atawa ruksakna alat-alat listrik disababkeun ku cai disemprot dina arah kalawan sudut nangtung kirang ti 60 darajat |
| 4 | Nyegah cai cipratan tina asup | Nyegah percikan cai tina sagala arah tina asup kana alat listrik sareng nyababkeun karusakan |
| 5 | Nyegah cai disemprot tina soaking di | Nyegah nyemprot cai tekanan rendah anu sahenteuna sahenteuna 3 menit |
| 6 | Nyegah gelombang badag tina soaking di | Nyegah nyemprot cai kaleuleuwihan anu tahan sahenteuna sahenteuna 3 menit |
| 7 | Nyegah immersion cai salila immersion | Nyegah épék soaking pikeun 30 menit dina cai nepi ka 1 jero méter |
| 8 | Nyegah immersion cai salila sinking | Nyegah épék soaking kontinyu dina cai kalayan jerona ngaleuwihan 1 méter. Kaayaan anu akurat ditangtukeun ku produsén pikeun unggal alat. |
The first numeral indicates the degree of protection against solid objects, while the second numeral represents the water resistance level. Protection against solid objects ranges across 6 tingkatan: tingkat 0 signifies no protection, and level 6 indicates complete dust-tightness, with protection increasing progressively from 0 ka 6. Nya kitu deui, water protection spans 8 tingkatan: tingkat 0 denotes no protection, and level 8 indicates suitability for prolonged submersion, with protection increasing progressively from 0 ka 8.
