IP ratings are described in IEC60529 " Degrees of protection provided by enclosures (IP code")...........................
The first characteristic numeral, 5, denotes protection against access to hazardous parts and/or protection against entry of solid bodies. In this case you must protect against access by a 1.0mm probe and the product is tested for dust protection. Dust is allowed to enter the product but it must not interfere with satisfactory operation of the product or impair safety....... The second numeral, 5, denotes protection against ingress of water. In this case your product is to be tested for protection against water jets. Pass fail criteria can include dielectric testing, determination if creepage and clearance distances have been compromised, etc...... The pass fail criteria for the contact with hazardous parts is cut and dried while for the dust and water ingress are somewhat subjective. The tests are well defined in the standard and require specialized equipment in most cases........... Hope this helps.........

We recently have been asked about compliance to "IP55" and an EMC standard numbered "G.692". "IP55" sounds like an "ingress protection" level to me. I'm drawing a complete blank on G.692. Is anybody familiar with these?
