6.6 Marking

6.6.1 Separator systems

The covers of separator systems shall be marked with "Separator", together with the class of cover in accordance
with EN 124. Furthermore, nameplates in a durable material e. g. stainless steel, shall be fixed to the separators in
a Clearly visible position, if possible on the inside.

If a separator and sludge trap are combined, a nameplate on the entrance to the separator manhole, or, on
exposed installations, on the separator itself is acceptable. if a separator and sludge trap are separate units a
nameplate for each is recommended.

The nameplate shall contain the following information:

— EN 858;

— class (I or il);

— _ nominal size (NS);

— volume of the separator, in I or m°

— volume of the sludge trap, in | or m*

— storage capacity for light liquids, in | or m?:

— depth of maximum storage quantity, in mm;

— _ year of manufacture;

-—~ manufacturer's name or mark;

-— mark of acertification body, where applicable.

Further marking may be added. Where ZA.3 covers the same information as this Clause, the requirements of
this Clause are met.
