Second Tier Documents—Process, Oil and Gas Industries
Abstract
This chapter addresses the contents of the IEC 61511 in detail. Each Part from one to three is briefly covered. Some of the following documents are referred to as “second tier” guidance in relation to IEC 61508. Due to the open ended nature of the statements made, and to ambiguity of interpretation, it cannot be said that conformance with any one of them automatically infers compliance with IEC 61508.
However, they cover much the same ground as each other albeit using slightly different terms to describe documents and life-cycle activities. IEC 61511 is intended as the process industry sector implementation of IEC 61508.
