Assessment Objectives

In addition to relevant policies, standards and procedures, the assessor shall examine, interview, and/or test to determine if appropriately scoped evidence exists to support the claim that:

• EMB-26_A01 the predetermined actions each Safety Instrumented Function (SIF) executes upon detection of a potentially hazardous event are documented in a Safety Requirements Specification (SRS).
  Assessment rigor: 1
  Origin: SCF Created
• EMB-26_A02 the detection conditions (e.g., trip points) that initiate each Safety Instrumented Function (SIF) are defined and documented.
  Assessment rigor: 3
  Origin: SCF Created
• EMB-26_A03 Safety Instrumented Functions (SIFs) within the Safety Instrumented System (SIS) automatically execute the predetermined actions when the defined detection conditions are met, without requiring operator intervention.
  Assessment rigor: 1
  Origin: SCF Created
• EMB-26_A04 each Safety Instrumented Function (SIF) is functionally tested at the defined proof test interval to confirm it executes the predetermined actions and the results are documented.
  Assessment rigor: 3
  Origin: SCF Created
• EMB-26_A05 bypasses or overrides of a Safety Instrumented Function (SIF) are authorized, time limited and logged.
  Assessment rigor: 2
