/ x' N r E* [% C. O5 ZAccording to sub clause 3.2.6, the marking of the IP numbers for degree of protection against ingress of dust, solid objects and moisture and, if desired, additional symbols shall be on the outside of the luminaire. Protection against submersion is marked with IP X8. According to Table J.2, the under water conditions (depth of immersion) shall be specified by the manufacturer. Is it enough if the marking (_ _ m) is given in the mounting instruction or shall we have the depth of immersion also together with the
