Emissivity & Radiometry FundamentalsYou are here
Master Stefan-Boltzmann law, Planck emission, Wien's law, and how emissivity affects all five required camera parameters.
Emissivity Correction Methods
Practice reference emitter, tape, paint, and RAT foil reflector methods. Learn emissivity tables for metals (0.05–0.80) and non-metals (0.85–0.98).
Severity Standards: NETA, ISO, ASHRAE
Memorize NETA ATS P1–P4 thresholds, ISO 18434-1 rotating machinery zones, and ASHRAE building envelope minimum ΔT requirements.
Fault Pattern Analysis
Study electrical (three-phase, transformer, capacitor), mechanical (bearing, steam trap), and building envelope (thermal bridging, moisture, air infiltration) thermal patterns.
Trending, QA/QC & Report Writing
Learn baseline comparison, rate-of-change analysis, Level I QA/QC responsibilities, and complete report documentation requirements.
Practice Exams & Weak Area Review
Take full 100-question timed practice exams. Focus on emissivity correction calculations and NETA threshold scenarios.
