FUNCTIONAL SAFETY DESIGN

In todays’ day and age, functional safety compliant control system is contractual demand. It is in place to ensure safety of personnel, equipment and product in case of critical failure. Control system is implemented in reference to functional safety standards BS EN 61508 and 61511 to make it safe. The machinery directive does not specify the use of any standard, but the use of a control system meeting the requirements of the harmonised standard(s) is one means of demonstrating compliance. We provide range of services to ensure our customers are in compliance with the safety standard and industry best practices. To ensure all the functional safety requirement are met, we ensure to get our functional safety design reviewed and signed off by TÜV-certified engineers.

For functional safety projects it is mandatory to produce specific design documentation. These are subject to SIL level requirements. The common safety design specifications are as listed below, these however by no means are the extent of it.

• Risk Assessment
• Functional Safety Workbook
• Safety Software Requirement Specifications (SSRS)
• Safety Matrix
• Safety Software Test Specifications (SSTS)
