Overview

This standard specifies principles for the design and selection - independent of the nature of the energy source - of interlocking devices associated with guards. Furthermore, it contains requirements in particular for electrical interlocking devices and includes parts of guards operating interlocking devices. This standard also provides measures to minimize defeat of interlocking devices in a reasonably foreseeable manner and is directed at users, machine manufacturers and manufacturers of interlocking devices. This standard is intended to replace DIN EN 1088. The significant changes with regard to the previous edition are an improved structure as a result of the differentiation and definition of four types of interlocking devices with a description of their technology and their advantages and disadvantages in the annexes, definition and consideration of "defeat in a reasonably foreseeable manner"; addition of measures required to minimize defeat possibilities have been changed and consideration of new technologies and addition of new informative Annexes G, H, I and J. The committee responsible for this standard is NA 095-01-04 GA "Schutzeinrichtungen, Sicherheitsmaßnahmen und Verriegelungen" ("Guards, safety measures and interlocking devices") at DIN.
