Ke kūʻai ʻana i kahi hōʻike LED, e ʻike ʻia ʻoe i ka hoʻoholo o ka helu IP e koho ai. ʻO ka ʻāpana mua o ka ʻike e hoʻomanaʻo ʻia ʻo ia ka hōʻike alakaʻi e pale i ka lepo. ʻO ka maʻamau maʻamau o waho e alakaʻi i ka pae wai wai e pono i mua IP65 a me hope IP54, hiki ke kūpono i nā ʻano like ʻole, e like me ka lā ua, ka lā hau a me ka lā ʻino.
Imately, pili ka koho o kahi hōʻike alakaʻi IPXX i nā koi. Inā hoʻokomo ʻia ka hōʻike alakaʻi i loko o ka hale a i ʻole semi-waho, a laila haʻahaʻa ka pono o ka papa IP, inā e hōʻike ʻia ke alakaʻi alakaʻi i ka lewa no ka manawa lōʻihi, a laila pono ka liʻiliʻi o ka hōʻike alakaʻi IP65. Inā hoʻokomo ʻia ma ka ʻaoʻao o ke kai a i ʻole ma lalo o ka wai ʻauʻau, a laila pono ka papa IP kiʻekiʻe.
ʻOi aku ka maʻamau, ʻo ka code IP e like me ka convention i wehewehe ʻia i ka maʻamau EN 60529 i ʻike ʻia penei:
IP0X = ʻaʻohe pale i nā kino paʻa waho;
IP1X = ka pā i pale ʻia mai nā kino paʻa i ʻoi aku ka nui ma mua o 50mm a me ke komo ʻana me ke kua o ka lima;
IP2X = ka pā i pale ʻia i nā mea paʻa i ʻoi aku ka nui ma mua o 12mm a me ke komo ʻana me ka manamana lima;
IP3X = ka pā i pale ʻia i nā mea paʻa i ʻoi aku ka nui ma mua o 2.5mm a me ke komo ʻana me kahi mea hana;
IP4X = ka pā i pale ʻia i nā kino paʻa i ʻoi aku ka nui ma mua o 1mm a me ke komo ʻana me kahi uea;
IP5X = ka pā i pale ʻia i ka lepo (a me ke komo ʻana me kahi uea);
IP6X = paʻa i pale ʻia i ka lepo (a me ke komo ʻana me kahi uea).
IPX0 = ʻaʻohe pale i ka wai;
IPX1 = ka pā i pale ʻia i ka hāʻule kū pololei o nā hāʻule wai;
IPX2 = ka pā i pale ʻia mai ka hāʻule ʻana o nā hāʻule wai me ke ʻano o lalo o 15°;
IPX3 = ka pā i pale ʻia i ka ua;
IPX4 = ka pā i pale ʻia i ka paʻi wai;
IPX5 = paʻa i pale ʻia i nā jet o ka wai;
IPX6 = ka pā i pale ʻia i nā nalu;
IPX7 = ka pā i pale ʻia i nā hopena o ka hoʻolulu ʻana;
IPX8 = paʻa i pale ʻia i nā hopena o ka hoʻohaʻahaʻa ʻana.
