Scope

This document specifies the design, manufacture, and testing requirements for electro-sensitive protective devices (ESPEs) employing stereo vision protection devices, and describes the special requirements for sensitive functions of ESPEs using stereo vision technology. This document is limited to the functionality of ESPEs and their mechanical connection methods. The detection principle is based on evaluating images from different observation points (stereo view) to determine distance information. This distance information is used to determine the position of objects. This document applies to: -- Vision-based ESPEs with fixed distances and orientations between different fixed imaging devices during manufacturing (stereo base); -- Vision-based ESPEs with a minimum distance of four times the stereo base from the distance-sensitive device to the detection zone; -- Vision-based ESPEs capable of detecting objects with a diameter of at least 5 pixels on the image plane; -- Vision-based ESPEs that do not require manual intervention for detection; -- Vision-based ESPEs that detect objects entering or existing in the detection zone; -- VBPDSTs using radiation in the range of 400 nm to 1,500 nm; -- VBPDSTs with detection capabilities within a range of 200 mm. This document does not address: -- The size or configuration of the detection zone and its configuration related to any specific application's hazardous components; -- Any mechanical hazardous states; -- Aspects required for complex classification or differentiation of detected objects; -- Aspects of mobile ESPE devices; -- Electromagnetic compatibility (EMC) emission requirements; Additional requirements and tests may apply to the following cases: -- Use of multispectral (color) technology; -- Setups other than those shown in Figure 1 of Section 4.1.2 (e.g., changing the background, adjusting the optical axis relative to the horizontal direction of the ground); -- Expected outdoor applications.
