This standard describes the positioning of safeguards, for instance electro-sensitive protective equipment, pressure-sensitive protective equipment, two-hand control devices and interlocking guards without guard locking, with respect of the approach speeds of persons and body parts which have been proven in practice. It describes a procedure, which allows determining safety distances between the detection zone of special sensing or actuating devices to a hazard zone. This standard cancels and replaces DIN EN 999, whereby the new calculation methods for the determination of the minimum distance when overreaching and circumventing electro-sensitive protective equipment and in case of indirect access to the hazard zone behind the electro-sensitive protective equipment in clause 6 and the new clause 9 "Interlocking guards without guard locking" have to be emphasized. Furthermore, the standard contains, in addition to new and revised practical worked examples, four new annexes. In particular, the standard deals with aspects of safety and occupational safety. Being published as a generic safety standard (type C standard), the standard addresses especially designers of machines, equipment and plants and standard writers of machine safety standards (type C standards). The Committee responsible for this standard is NA 095-01-04 GA "Gemeinschaftsarbeitsausschuss NASG/NAM/DKE: Schutzeinrichtungen, Sicherheitsmaßnahmen und Verriegelungen" ("Joint Working Committee NASG/NAM/DKE: Guards, safety measures and interlocking devices") at DIN.
