Safety Validation for Machinery Safety

The fifth step to machinery safety: Safety validation

April 12, 2023

MC-Safety-Validation-for-Machinery-Safety-1

In a machine’s lifecycle, the topic of validation plays a major role in safety – for both manufacturers and operators alike. Therefore, workplace directives and standards, such as ISO 13849IEC 62061 and IEC 61508, require you, as manufacturers and operators of machinery, to validate your safety systems. To do this, it is essential to be well informed about the machine lifecycle as well as the implementation of the required protective measures.

Following a safety inspection, the question arises as to whether all safety-related risks have been considered and solved with the right measures. Validation is the only way of finding out whether the necessary risk reduction measures have been correctly implemented and whether the machinery therefore demonstrably complies with the relevant standards and regulations!

Customized validation – the right level to suit every requirement

What depth of validation is necessary and useful?

Pilz offers a range of services matched specifically to you, to validate your machinery efficiently using a structured method in the categories of machinery safety, risk minimization, functional safety and other legal requirements. Accordingly, as a machine manufacturer or operator, you can choose between three levels of validation service, precisely tailored to the project and requirements.
