IP4LX What is the LX?
IP4LX What is the LX?
(OP)
I have a customer inquiry from Argentina who is asking for a IP4LX enclosure. My googles have come up with only chinese web sites. I've translated the page, but I am still not clear.
Can someone please define IP4LX for me.
Thanks!

RE: IP4LX What is the LX?
IEC requires more digits. The first 4 would be protected against access of people using a wire or solid objects grather than on mm diameter; in the second position would be protected against splashing water. In NEMA the 4 is for fire hose type water application. NEMA 4X corresponds closely to IP 66. NEMA 4X is protected from external icing, hosedown, corrosion and is gasketed. The "L" in IP4LX beats the L out of me unless it is liquid. In NEMA the supplemental marking includes capabilities such as rain tight, rain proof, water tight, corrosion resistant, drip tight and dust tight.

But my search came up with this chinese site that plainly refers to IP4LX. It makes mention to IEC 529 but clearly does not mimic it.
I've attached the chinese site.

IPXXXX
Whereby
1st X means Protection against ingress of solid foreign objects starting from 0 (no protection) to 6 (dust tight) or an X
2nd X means Protection against ingress of water with harmful effects starting from 0 (no protection) to 8 (continuous immersion) or an X
3rd is optional and means Protection against access to hazardous parts starting with A(back of hand) up to D (wire) or an X
4th is optional and uses the letters H (High Voltage apparatus), M (Motion during water test), S (Stationary during water test) and W (Weather conditions).
So, still not sure what the "L" means.
This is one of the reasons I do not like IP classifications even though I work in IP land. I much prefer the NEMA method of classification, it seems to be so much more straightforward and workable.
