MS-PC 2015: Performance Specifications for Instrumentation Systems Designed to Measure Radon Gas in Air Page 16 of 20 Proportionality (Sec. 7.3) Requirements: Each IPE = 0 ± 25% and COV ≤ 15% for each set of five devices, and the difference between the average IPE(low concentration) and the average IPE(high concentration) must be between −15% and +15%. Note that a test in either a high radon concentration or a high integrated radon concentration is required (not both).
