IEC 62046:2018 pdf download.Safety of machinery – Application of protective equipment to detect the presence of persons
1 Scope
This International Standard specifies requirements for the selection, positioning, configuration and commissioning of protective equipment to detect the momentary or continued presence of persons in order to protect those persons from dangerous part(s) of machinery in industrial applications. This standard covers the application of electro-sensitive protective equipment (ESPE) specified in IEC 61 496 (all parts) and pressure sensitive mats and floors specified in ISO 1 3856-1 . It takes into account the characteristics of the machinery, the protective equipment, the environment and human interaction by persons of 1 4 years and older. This document includes informative annexes to provide guidance on the application of protective equipment to detect the presence of persons. These annexes contain examples to illustrate the principles of this standard. These examples are not intended to be the only solutions to a given application and are not intended to restrict innovation or advancement of technology. The examples are provided only as representative solutions to illustrate some of the concepts of integration of protective equipment, and have been simplified for clarity, so they may be incomplete.

3 Terms, definitions and abbreviated terms
3.1 Terms and definitions For the purposes of this document, the following terms and definitions apply.3.1 .1 active opto-electronic protective device AOPD device whose sensing function is performed by opto-electronic emitting and receiving elements detecting the interruption of optical radiations generated, within the device, by an opaque object present in the specified detection zone (or for a light beam device, on the axis of the light beam) [SOURCE: IEC 61 496-2:201 3, 3.201 ] 3.1 .2 actuation of an ESPE detection of an object causing the OSSD(s) to go to the OFF-state 3.1 .3 active opto-electronic protective device responsive to diffuse reflection AOPDDR device, whose sensing function is performed by opto-electronic emitting and receiving elements, that detects the diffuse reflection of optical radiations generated within the device by an object present in a detection zone specified in two dimensions [SOURCE: IEC 61 496-3:2008, 3.301 ] 3.1 .4 blanking optional function that permits an object of a size greater than the detection capability of the ESPE to be located within the detection zone without causing an OFF-state of the OSSD(s) Note 1 to entry: Blanked beams are monitored for continued interruption of light.. [SOURCE: IEC 61 496-1 :201 2, 3.1 , modified – Note 1 to entry has been modified, Note 2 to entry has been removed] 3.1 .5 detection capability sensing function parameter limit specified by the supplier that will cause actuation of the protective equipment [SOURCE: IEC 61 496-1 :201 2, 3.3, modified – “electro-sensitive” has been removed before “protective equipment”] 3.1 .6 detection zone zone within which a specified test piece will be detected by the electro-sensitive protective equipment (ESPE) Note 1 to entry: ISO 1 3856-1 uses the term “effective sensing area” when describing pressure-sensitive mats and floors. In this document the terms “detection zone” and “effective sensing area” are used synonymously. [SOURCE: IEC 61 496-1 :201 2, 3.4, modified – Note 1 to entry has been added]
