Neqsim Standards Lookup Industry standards lookup and compliance tracking for NeqSim engineering tasks. USE WHEN: any engineering task requires standards compliance (API, ISO, NORSOK, DNV, ASME, EN, ASTM), risk assessment, or safety analysis. Provides equipment-to-standards mapping, database query patterns, results.json schema for standards_applied, and risk standards quick-reference.

Reference for identifying, applying, and documenting industry standards compliance
in every engineering task. All tasks — Quick, Standard, or Comprehensive — must
identify applicable standards proportional to task depth.
Standards Identification (MANDATORY First Step)
Before any simulation or analysis, identify applicable standards:
Task Scale Standards Requirement Quick 1-line note: "Per [STANDARD]" or "N/A — property lookup" Standard Table of applicable standards with scope and status Comprehensive Full table with clause numbers, design values, and compliance evidence

Post-Simulation Standards Check Pattern After running a process simulation, check key results against standards:
# Example: Check separator K-factor against NORSOK P-001
k_factor = separator.getInternalDiameter() # Get from results
# Look up limit from standards database
if k_factor < 0.12 or k_factor > 0.15:
print("WARNING: K-factor outside NORSOK P-001 range (0.12-0.15 m/s)")
standards_status = "FAIL"
