Method Compliance Assessment

Preparing companies for the SIL Certification of products, organisations and people

Method Compliance Assessment are specialists in preparing companies for the SIL Certification of products. We help manufacturers enter new markets with SIL Certification to 61508, and we help users ensure products in existing systems can be proven to be compliant, including the 61511 ‘prior use‘ technique.

Method provides practical, down-to-earth, sleeves rolled up support for businesses. Whenever we do consultancy, we ensure the work we do is compliant with the relevant standards and guidelines – and that you also know what’s expected of you and others to achieve the same end. We’ll also do all we can to suggest improvements in your approach.

We are part of the Method Safety and Security group. Our sister company Method Functional Safety Ltd provides TUV 61508 H/W and S/W training to give your team a clear understanding of the regulations, and to help them keep your business working to the standards.

Case Study: 61508 Proven in Use Assessment

A component manufacturer contacted =Method to determine whether it was possible to obtain SIL certification for an existing product. The valve had been on the market for a long period and was developed prior to introduction of functional safety standards. The manufacturer was not familiar with IEC 61508 and none of their current product range had been assessed against the standard.

61508 Prior Use Assessment Case Study

Case Study: 61511 Prior Use

Following an inspection from the HSE, a process industry operator required evidence that a device installed in an existing Safety Integrated Function (SIF) was fit for purpose. The operator contacted =Method for support in determining whether the installed device met the requirements for a SIL 1 function.

Case Study: 61508 Proven through Design route – existing device

A component manufacturer had identified that they would have significant market advantage if they were able to claim SIL compliance for an existing product that was relatively new to market. They contacted =Method for support in understanding how difficult it would be to demonstrate compliance.

Case Study: 61508 Proven through Design - New Product Development

=Method was contacted by a product developer requiring support to understand how to develop a new device, such that the finished product could be marketed as ‘SIL Compliant’. =Method worked closely with the client to develop a programme of support activities that would maximise the likelihood of a successful product development with minimal impact to the product development cost.
