This document encompasses recommendations for planning, installation and operation (incl. maintenance) of process analyzer technology measuring equipment in process industry safety instrumented systems. It covers all necessary steps for the qualification of safety equipment and supplements the safety management of safety instrumented system equipment through the addition of special requirements for process analyzer technology equipment. This document does not encompass the entire safety management of safety instrumented system equipment.<\/p>\n
The term \u201cqualification\u201d used in this recommendation refers exclusively to the testing of the suitability of the process analyzer technology system for use in a safety instrumented system device. It is different from the term “qualification” used in the pharmaceutical environment.<\/p>\n
