Q: What conditions must a design approval holder clarify in its procedures if it chooses to use the derogation under point 21.A.804(b) to omit marking on a part?

The design approval holder must clarify the conditions (e.g. the minimum dimensions of a (flat) area on a part suitable for marking) in which the marking on the part may be completely or partially omitted. This can also be supported by examples of parts or cases when certain parts do not have to be marked.

Q: When a design approval holder uses the derogation under point 21.A.804(b), what should the relevant design data (e.g. drawings) specify regarding information that could not be marked on the part?

The relevant design data (e.g. drawings) should specify the contents and location of the information that could not be marked on the part (i.e. the information to be provided in the authorised release document or on the container).
