This paper describes the Class 1 assessment of the Rosemount 3051 Pressure Transmitter and the Class 2 assessment of the Rosemount 644 Temperature Transmitter using Emphasis at SIL 3 and 2 respectively. Emerson has pursued many approvals and certifications on these transmitter platforms. The audit for each of these assessments is unique and probes information at varying levels of detail. As compared to other approvals and certifications audits, the Emphasis assessment is a much more productive and in-depth review of design and project materials. The assessment is focused on reviewing quality procedures, design and project artefacts that prove practical engineering practices, and processes that would lead to good product design. This paper describes Emerson’s approach to the assessment. For this assessment, Emerson answered the over 300 assessment questions and provided over 150 archived documents as evidence for each individual product. Throughout the assessment, Emerson’s knowledge of IEC 61508, quality standards, product development processes and software engineering practices showed that, as a smart device manufacturer, Emerson is approaching design processes and procedures with the necessary rigor to produce devices capable of meeting the most stringent requirements.
