Confusion over IP Ratings?
When does IP67, 68, 69 = IP66?
??NEVER ??, unless its been tested & marked for it.
Still confused? Non-Ex and Ex Training for Manufactures, Testing Laboratories, Notified Bodies, and Certification Bodies would solve many of these issues at the heart of the problem.
??% Facts - These are "Restricted" Markings
IP67 = IP64
IP68 = IP64 and IP67
IP69 = IP64
? Correct Methods of Marking and Testing - These are "Versatile" Markings
IP66 / 67
IP66 / 68 (Covers IP 67)
IP66 / 68 / 69
IP66 / 69 (Does not cover IP 67 or 68)

3 年The perpetual Ingress question. There should never be any confusion, IP66/67/68/69 are all different tests set out clearly in the standards. The same way that NEMA 4X is NOT comparable to IP66 or DTS01.
