SAFE & SECURE AUTOMATION
When designing electrical equipment, we consider the safety application standard ČSN EN ISO 13849-1, which uses a risk graph to determine the required safety level and works with the term “required performance level PLr”; less so the ČSN EN 62061 standard, where the method used represents a numerical approach and works with the term “required safety integrity level SIL”.
The general principles for design, assessment, and risk reduction are covered by the type A standard, ČSN EN ISO 12100. The risk assessment is performed for all hazards, the standard defines a sequence of steps, starting with the determination of the machine function.
