Standards, Reporting and Program Implementation
Standards landscape
Know which document governs which task: ISO 18434-1 for condition monitoring thermography, ISO 18436-7 for personnel certification categories, ASTM E1934 for electrical and mechanical inspections, IEC 62492-1 and -2 for industrial process measurement, ISO 6781 and ASTM C1060 for qualitative building envelope work, NFPA 70B for electrical maintenance programmes and NETA acceptance and maintenance specifications for electrical testing criteria. Cite the standard that matches the application, not the one that is easiest to remember.
Report content
A defensible report states scope, limitations and method; equipment make, model, calibration date and lens; environmental and load conditions including ambient temperature, wind, humidity, distance, emissivity and reflected apparent temperature; the findings with images and severity classification; recommended corrective actions; and the thermographer identification with certification level. Severity criteria must be defined before the survey, not invented per finding.
Programme implementation
A working programme has defined routes and inspection frequencies, baselines and trending, qualified personnel, written procedures, safety integration, QA review of reports, a corrective action loop and verification re-inspection after repair. KPIs such as findings closed out matter more than images captured.
Traps
- Quoting a standard that does not cover the application.
- Omitting load, weather or calibration data so the reading cannot be reproduced.
- Presenting a severity class with no stated criteria.
- Overstating certainty on a qualitative building survey.
- Never re-inspecting to confirm the repair worked.
Worked example
A report line for a switchgear anomaly should read: 400 A feeder, 62 percent loaded, ambient 24 C, wind under 2 m/s, emissivity 0.95 on taped reference, distance 3 m, delta 22 K versus sibling phases, severity per the site table, repair recommended and re-inspection scheduled. Without those fields the finding cannot be audited.
