Outlines rigorous type tests and functional tests that devices must pass to prove compliance. Relationship Between ESPE Types and Safety Levels IEC 61496-1:2020
Covers electrical supply, fault detection, Output Signal Switching Devices (OSSDs) , and measures against common-cause failures. iec 61496-1 pdf
It applies to devices designed to detect persons or parts of persons without physical contact, such as active optoelectronic protective devices (AOPD) . Outlines rigorous type tests and functional tests that
Mandates testing for ambient temperature, humidity, vibration, and resistance to electromagnetic interference (EMC). It is a technology-neutral "Part 1" standard, meaning
To ensure an appropriate level of safety-related performance is achieved and maintained through built-in self-checks and functional tests.
IEC 61496-1 focuses on the functional and design requirements of ESPE used as part of a safety-related system. It is a technology-neutral "Part 1" standard, meaning it provides the general framework that applies to all ESPE regardless of the specific sensing technology used.
