1° Which serves to ensure a safety function;
2° Which is placed on the market in isolation;
3° Whose failure or malfunction endangers the safety of persons;
4° Which is not essential to the operation of the machine or which, from the point of view of operation alone, could be replaced by an ordinary component.
