Safety Integrity Level and Performance Levels

Safety Integrity Level and Performance Levels

How safe is your production process?

As a manufacturer of an end product and / or as a machine engineer within the supply industry, you will constantly be seeking ways to optimise your production process with a view to increasing production, reducing waste flows and minimising disruptions to that process in so far as possible. There are numerous things that will afford the manufacturer a better market position, even during the improvement process.

In addition to the aforementioned improvement processes, all of which are directly linked to production, European legislation also requires you to deal with indirect issues, such as safety and failure rate calculations. These are terms that were given less consideration in the past and that now form the subject of much interest.

In order to help our customers familiarise themselves somewhat with this complex subject matter, which is virtually unknown to the majority of them, the firm Pilz and Moekotte held a seminar on 10 December, which touched upon a number of topics:

  • Why have Safety Integrity Levels ( SILs ) ?
  • The construction and design of safety systems in accordance with the IEC 62061 standards
  • Functional safety and failure rate calculations
  • Why are Performance Levels ( PL ) necessary?
  • Discrepancies in the application of current standards EN 954-1 and ISO 13849-1
  • Reliability analyses of safety circuits
