ASSESSMENT OF THE UNCERTAINTY OF MEASUREMENT RESULTS OF HEXACHLOROBUTADIENE IN INDOOR AIR

摘要

Within the frame of the development of a method for the measurement of concentration levels from 0.003 to 10 parts per billion by volume of hexachlorobutadiene in indoor air an assessment has been performed of the uncertainty of the measurement results. This assessment - fully based on the principles of the ISO Guide to the Expression of Uncertainty in Measurement (ISO-GUM) - has shown that - even for the measurement of such extremely low concentrations - uncertainty levels of < 25% (95% confidence) are achievable.
