Standards are agreements between different interest groups (manufacturers, consumers, notified bodies, health and safety authorities and governments). They describe the state of the art at the time they are produced. Depending on the application site of the machine or product, various statutory regulations may apply, making it necessary to apply various standards. Selecting correctly helps the machine manufacturer to comply with statutory requirements.
Overview of basic standards (A+B standards)

Safeguards are necessary to provide operators with as much protection as possible from hazards that may arise during machine operation. It is the duty of the manufacturer to select an appropriate safeguard. This must neither increase the risk nor obstruct work on the machine. It's in the manufacturer's interests to provide precise justification for any decision not to equip moving parts with safeguards.
