Shenhai Explosion-Proof
Ko nga momo momo taputapu hiko pahū-pahū me whai paerewa whakamarumaru pouaka motuhake. Ko enei paerewa, e mohiotia ana ko nga tohu tiaki, denote the casing’s capability to block external objects from penetrating its interior and to provide resistance against water ingress. E ai ki nga “Nga Waeine Tiaki e Hoatuhia ana e nga Kainga (Waehere IP)” (GB4208), Ko te tohu tiakitanga a te kaitohu e tohuhia ana e te waehere IP. This code comprises the initials IP (International Protection), followed by two numerals and sometimes optional additional letters (which are occasionally omitted).
| Tau | Awhe whakamarumaru | Whakamaramatia |
|---|---|---|
| 0 | Karekau he parenga | Kaore he whakamarumaru motuhake ki te wai, makuku ranei |
| 1 | Aukati i nga pata wai kia kore e uru ki roto | Nga pata wai e taka poutū ana (pēnei i te condensate) e kore e pakaru nga taputapu hiko |
| 2 | Ka titaha ki 15 tohu, Ka taea tonu te aukati i nga pata wai kia kore e uru ki roto | Ina titaha poutū te taputapu ki 15 tohu, e kore e pakaru te wai o te wai ki te taputapu |
| 3 | Aukati i te wai maputia kia kore e uru ki roto | Aukati i te ua, i te kino ranei o nga taputapu hiko na te wai i maputia ki nga ahunga me te koki poutū iti iho i te 60 tohu |
| 4 | Aukati i te pakaru o te wai kia uru mai | Aukati i te pakaru o te wai mai i nga huarahi katoa kia kore e uru ki nga taputapu hiko me te kino |
| 5 | Aukati i te wai maputia kia kore e uru ki roto | Aukati i te rehu wai pehanga iti ka roa mo te iti rawa 3 meneti |
| 6 | Aukati nga ngaru nunui kia kore e uru ki roto | Aukati i te nui o te rehu wai ka roa mo te iti rawa 3 meneti |
| 7 | Aukati i te ruku wai i te wa e ruku ana | Aukati i nga paanga o te waikura mo 30 meneti i roto i te wai ki te 1 mita te hohonu |
| 8 | Aukati i te rumaki wai i te wa e totohu ana | Aukati i nga paanga o te wai i roto i te wai me te hohonu rawa atu 1 mita. Ko nga tikanga tika kua tohua e te kaiwhakanao mo ia taputapu. |
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 taumata: taumata 0 signifies no protection, and level 6 indicates complete dust-tightness, with protection increasing progressively from 0 ki 6. Waihoki, water protection spans 8 taumata: taumata 0 denotes no protection, and level 8 e whakaatu ana i te whaihua mo te wahanga roa, with protection increasing progressively from 0 ki 8.
