How should the marking look?

The three elements as set out above should be presented in sequence from left to right. The colours are not specified but the marking must be visible, legible and indelible. The intials "CE" will always be present at the beginning of the marking. The presence of the other elements will depend on the circumstances. If one or more notified bodies have been involved in any part of the compliance process then their respective number(s) must follow the "CE". The notified body number(s) must always have four digits even where the leading digits are "0". If a finished product includes a module bearing one notified body number and the finished product is assessed by a different notified body then both numbers must appear on the finished product after the "CE". Similarly, if one notified body assesses health & safety compliance and a different notified body assesses spectrum compliance, both numbers must appear on the finished product. A further example might be where another applicable directive (such as the toys directive) has involved notified body assessment and a different notified body is consulted for the R&TTE directive. After the notified body number(s) or directly after the "CE" if no notified body is involved comes the "alert symbol" (also called the "alert sign" or "alert mark") for equipment in Class 2 – no further marking is required for equipment in Class 1.
