    Description of IP ratings in BS 7671

    Hi Can someone point me to the description of IPXXB and IP2X in BS 7671. I know what they are and the requirements of each of them are, but I cannot locate the description in the Big Blue Book. Appendix 5 on page 450 has the details of IP 0, 3, 4, 5 & 6X but not the other 2. Cheers
