What is PD IEC/TS 61496-4-3— Electro-sensitive protective equipment about?
PD IEC/TS 61496-4-3 is a part of an international multi-series standard that focuses on the safety aspects of electro-sensitive protective equipment.
PD IEC/TS 61496-4-3 specifies requirements for the design, construction, and testing of electro-sensitive protective equipment (ESPE) designed specifically to detect persons or parts of persons as part of a safety-related system, employing vision-based protective devices (VBPDs) using stereo vision techniques (VBPDST) for the sensing function.
PD IEC/TS 61496-4-3 directs special attention to features that ensure that an appropriate safety-related performance is achieved. An ESPE includes optional safety-related functions, the requirements for which are given in Annex A of IEC 61496-1:2012 and PD IEC/TS 61496-4-3.
PD IEC/TS 61496-4-3 is limited to vision-based ESPEs with distances (stereo base) and directions between the different imaging devices fixed during manufacture.
- It is limited to vision-based ESPEs, with a minimum distance from the sensing device to the detection zone of 4 times of the stereo base
- It is limited to vision-based ESPEs that can detect objects with at least 5-pixel diameter in the image plane
- It is limited to vision-based ESPEs that do not require human intervention for detection
- It is limited to vision-based ESPEs that detect objects entering into or being present in a detection zone
- It is limited to VBPDSTs employing radiation at wavelengths within the range of 400 nm to 1500 nm
Note 1: PD IEC/TS 61496-4-3 does not address those aspects required for complex classification or differentiation of the object detected.
Note 2: PD IEC/TS 61496-4-3 does not consider the aspects of a moving ESPE installation.
Who is PD IEC/TS 61496-4-3— Electro-sensitive protective equipment for?
PD IEC/TS 61496-4-3 on Electro-sensitive protective equipment is useful for:
- Safety certification providing entities for electro-sensitive protective equipment
- Suppliers and dealers of electro-sensitive protective equipment
- Designers of electro-sensitive protective equipment

Why should you use PD IEC/TS 61496-4-3— Electro-sensitive protective equipment?
Electro-sensitive protective equipment (ESPE) is applied to machinery presenting a risk of personal injury. It provides protection by causing the machine to revert to a safe condition before a person can be placed in a hazardous situation.
The electro-sensitive protective equipment, as its name indicates, is very useful for the safety of the persons operating the heavy machinery located in hazardous areas. It performs the function of detecting human interference with help of sensors and generates the output denoting the hazard. This helps the users to acknowledge the danger and leads them to move into a secure zone.
PD IEC/TS 61496-4-3 presents you with appropriate design requirements that include functional and environmental requirements in order to design and construct highly efficient and reliable electro-sensitive protective equipment that is in compliance with international standards.
PD IEC/TS 61496-4-3 also lays down the technicalities for methodologies carrying out several tests to verify the functionality and performance characteristics of electro-sensitive protective equipment. It gives you detailed information about the various test conditions and different operating conditions that should be considered while executing the tests. This helps you to ensure the effective and reliable working of the electro-sensitive protective equipment.
It is essential that the technical specification concerned with the electro-sensitive protective equipment should be accurate and effective, due to the complexity of the technology. Thus, PD IEC/TS 61496-4-3 provides its users a specification that is analyzed and verified, established for suitable use in safety-related applications.
