Thermodynamic Proficiency Testing
NAPT’s Thermodynamic Proficiency Testing programs help labs demonstrate competence, meet accreditation standards, and strengthen quality control across high-stakes industries.
What Is Thermodynamic Proficiency Testing?
Thermodynamic proficiency testing is the process of assessing a laboratory’s ability to accurately measure thermal quantities—such as temperature, humidity, and heat flow—using traceable artifacts.
The Impact of PT Testing
Why It Matters
Accurate thermodynamic measurements are essential for product safety, process control, and energy efficiency. Even small deviations can lead to costly rework, compliance issues, or compromised product quality.
Participating in thermodynamic proficiency testing helps your lab:
- Maintain ISO/IEC 17025 accreditation and compliance standards
- Detect out-of-tolerance instruments or techniques to ensure reliable measurements
- Support internal quality assurance and quality control programs
- Increase customer trust and operational credibility through accurate calibration
