ʻO ka IP Code a i ʻole Ingress Protection Code i wehewehe ʻia ma IEC 60529 e hoʻokaʻawale a hāʻawi i kahi alakaʻi i ka pae o ka pale i hāʻawi ʻia e nā casings mechanical a me nā pā uila e kūʻē i ka intrusion, ka lepo, ka hoʻopili ʻana i ka pōʻino, a me ka wai. Ua paʻi ʻia ma ka European Union e CENELEC e like me EN 60529.

Manaʻo ka maʻamau e hāʻawi i nā mea hoʻohana i ka ʻike kikoʻī hou aku ma mua o nā huaʻōlelo kūʻai ʻole e like me ka wai wai. No ka laʻana, ʻo kahi kelepona paʻa i helu ʻia ma IP67 he "pale lepo" a hiki ke "hoʻokomo ʻia i loko o 1 mika wai maʻemaʻe a hiki i 30 mau minuke". Pēlā nō, pale ʻia kahi kumu uila i helu ʻia ʻo IP22 mai ka hoʻokomo ʻana i nā manamana lima a ʻaʻole ia e lilo i mea palekana i ka wā o ka hoʻāʻo ʻana i ʻike ʻia i ka wai kū pololei a kokoke paha i ka wai. ʻO IP22 a i ʻole IP2X nā koi liʻiliʻi maʻamau no ka hoʻolālā ʻana i nā mea uila no ka hoʻohana ʻana i loko.

Hōʻike nā huahelu i ka kūlike me nā kūlana i hōʻuluʻulu ʻia ma nā papa ma lalo. Hoʻohana ʻia ka huahelu 0 inā ʻaʻole mālama ʻia. Hoʻololi ʻia ka huahelu me ka leka X inā lawa ʻole ka ʻikepili i hōʻiliʻili ʻia e kau i kahi pae palekana. Hiki ke emi ka pono o ka mea hana, akā ʻaʻole hiki ke lilo i mea palekana. Inā makemake ʻoe e ʻike hou aku, e kaomi maanei.
