Safety Validation
One of the topics of the Health and Safety concept in the industrial field is given by the verification of the machine/plant/technical equipment before the start of productive use in accordance with the safety requirements.
This principle can be also applied to tasks and activities related to the machines and technical equipment themselves.
This is what is normally called Safety Validationand the result of this process can then be reported in the Company’s Risk Assessment Plan.
In practice, we propose the following activities:
• Definition of safety validation protocols
• Verification of machines and industrial plants – Health & Safety requirements
• Safety verification of activities and operative tasks led by personnel
• Verification and infield inspections – Safety functions behavior
• Verification of machines and industrial plants – Functional safety aspects
• Interface with Client’s safety teams and third parties (Bodies, Notified Bodies, …)s
Techincal Standards:
EN 13849-1
EN 13849-2
EN 62061
IEC 61508
IEC 61511
The final safety validation is also expressly required by the Functional Safety Standards related to machines, to certify that the final safety results are aligned with those expected after the design phase, in accordance with the applicable reliability parameters (SIL or PL).
The purpose of the validation process is therefore to confirm that the design of the safety-related parts of the control system complies with the standards and the overall safety requirements of the machinery.
The validation must demonstrate that each of the safety-related parts meets the regulatory requirements and that the system behavior is in line with what is defined and documented at the design level (SIL/PL calculation).
NEMOTEC activity includes:
• Design of the functional safety validation protocol (SIL functions)
• Design of the functional safety validation protocol (PL functions)
• Design of the software validation protocol
• Safety testing and functional safety verification.
• Interface with the Customer’s safety teams and Notified Bodies
