Short Desciption:
EC 61508 has been in use for several years since the final parts were released in 2000. Although written from the perspective of a bespoke system, it is more commonly used to certify products for a given SIL level. Valid product certification schemes must involve the assessment of specific product design details as well as an assessment of the safety management system of the product manufacturer and the personnel competency of those professionals involved in the product creation.

Summary:
An open certification scheme based on a safety case will help manufacturers design products with better safety integrity because important requirements of the standard are less likely to be missed in an assessment. The safety case explanations have been used to more rapidly convince manufacturers of the need and value of IEC 61508 requirements. Personnel are more likely to get proper training and competency records are more likely to be kept and au dited. The open scheme will help resolve issues of interpretation by providing clear examples that can be debated if disagreement exists. An open scheme based on the use of a safety case will ensure that all needed documents are prepared. An open certification scheme will help end users by provid ing clear visabililty into the certification effort. A prospective customer can read the certification and see what level of assessment has been done. Those that wish may dig further and upon permission of the vendor review the entire safety case document. The primary disadvantage of the safety case approach is a higher initial cost for a manufacturer for the first project. Subsequent projects will benefit from any existing work and the overall cost for several projects should be lower when compared to conventional assessment techniques.
