The machine safety standards have been experiencing some changes recently.
There are numerous potential risks around machinery or equipment, which can be divided into 2 parts, such as safety risks and health hazards, like sharp edges, gears, chains, rotary axes, spinning blades and levers.
Therefore, ISO 13849-1:2015 establishes the safety requirements and guidelines, and the design and integration principles for control system parts related to safety (SRP / CS), including software design. For SRP /CS parts, it specifies characteristics that include the required performance level to carry out the safety functions.
Each of these safety function documents provides a guide for a specific safety feature based on functional requirements, selection of equipment and performance level requirements, including the installation and wiring plan, the configuration, verification and validation, and the calculation of the level of performance.
