Muyezo wa IP (Ingress Protection) ndi mulingo wapadziko lonse lapansi pakuwunika ndikuyika mulingo wachitetezo cha zida zamagetsi. Amakhala ndi manambala awiri omwe akuyimira mlingo wa chitetezo ku zinthu zolimba ndi zamadzimadzi. Nambala yoyamba imasonyeza mlingo wa chitetezo ku zinthu zolimba, ndipo mtengo wake umachokera ku 0 mpaka 6. Tanthauzo lenileni ndi ili:
0: Palibe gulu lachitetezo, silimapereka chitetezo kuzinthu zolimba.
1: Kutha kutsekereza zinthu zolimba ndi m'mimba mwake kuposa 50 mm, monga kukhudzana mwangozi ndi zinthu zazikulu (monga zala).
2: Kutha kutsekereza zinthu zolimba ndi m'mimba mwake kuposa 12.5 mm, monga kukhudzana mwangozi ndi zinthu zazikulu (monga zala).
3: Kutha kutsekereza zinthu zolimba ndi m'mimba mwake kuposa 2.5 mm, monga zida, mawaya ndi zinthu zina zazing'ono kuti zisakhudze mwangozi.
4: Kutha kutsekereza zinthu zolimba ndi m'mimba mwake kuposa 1 mm, monga zida zazing'ono, mawaya, malekezero a waya, ndi zina zambiri kuti zisakhudze mwangozi.
5: Itha kuletsa kulowerera kwa fumbi mkati mwa zida ndikusunga mkati mwa zida zoyera.
6: Chitetezo chathunthu, chotha kuletsa kulowerera kulikonse kwa fumbi mkati mwa zida.
Nambala yachiwiri ikuwonetsa kuchuluka kwa chitetezo ku zinthu zamadzimadzi, ndipo mtengo wake umachokera ku 0 mpaka 8. Tanthauzo lake ndi motere:
0: Palibe gulu lachitetezo, silimapereka chitetezo chilichonse kuzinthu zamadzimadzi. 1: Wokhoza kutsekereza kukhudzika kwa madontho amadzi akugwa pazida.
2: Itha kuletsa kukhudzika kwa madontho amadzi akugwa chipangizocho chikapendekeka pamakona a madigiri 15.
3: Itha kuletsa kukhudzika kwa madontho amadzi akugwa chipangizocho chikapendekeka pamakona a madigiri 60.
4: Itha kuletsa kugunda kwamadzi pazida pambuyo potengera ndege yopingasa.
5: Ikhoza kulepheretsa kukhudzidwa kwa madzi opopera pazida pambuyo potsata ndege yopingasa.
6: Wokhoza kuletsa kukhudzidwa kwa majeti amadzi amphamvu pazida pansi pamikhalidwe inayake.
7: Kutha kumiza chipangizocho m'madzi kwa nthawi yochepa popanda kuwonongeka. 8: Kutetezedwa mokwanira, kutha kumizidwa m'madzi kwa nthawi yayitali popanda kuwonongeka.
Chifukwa chake, nyali zakunja zapanja za rattan nthawi zambiri zimafunika kukhala ndi mulingo wapamwamba wosalowa madzi kuti zitsimikizire kuti zikugwiritsidwa ntchito bwino nyengo zosiyanasiyana. Magulu odziwika bwino osalowa madzi amaphatikizapo IP65, IP66 ndi IP67, pomwe IP67 ndiye giredi lachitetezo kwambiri. Kusankha mulingo woyenera wosalowa madzi kumatha kuteteza kuwala kwa rattan kumvula ndi chinyezi, kuwonetsetsa kukhazikika kwake komanso moyo wautali.
