ASTM D6399-2018 测量飞行器机舱内空气质量用仪器和方法的选择指南 Standard Guide for Selecting Instruments and Methods for Measuring Air Quality in Aircraft Cabins

1.1 This guide covers information and guidance for the selection of instrumentation and test methods for measuring air quality in aircraft passenger cabins as well as in areas limited to flightcrew access. 1.2 This guide assumes that a list of pollutants to be measured, or analytes of interest, which are present, or may be present, in aircraft cabins is available. 1.3 This guide provides information and guidance to identify levels of concern pertaining to public and occupational exposures to relevant air pollutants. This guide does not address levels of concern, if any, related to degradation of materials or aircraft components because of the presence of air pollutants. 1.4 Based on levels of concern for public and occupational exposures for each pollutant of interest, this guide provides recommendations for developing three aspects of data quality objectives (a) detection limit; (b) precision; and (c) bias. 1.5 This guide summarizes information on technologies for measurement of different groups or classes of air pollutants to provide a basis for selection of instruments and methods. The guide also identifies information resources on types of available measurement systems. 1.6 This guide provides general recommendations for selection of instruments and methods. These recommendations are based on concepts associated with data quality objectives discussed in this guide and the information on available instruments and methods summarized in this guide. 1.7 This guide is specific to chemical contaminants and does not address bioaerosols, which may be present in the cabin environment. 1.8 This guide does not provide details on use or operation of instruments or methods for the measurement of cabin air quality. 1.9 This guide does not provide information on the design of a monitoring strategy, including issues such as frequency of measurement or placement of samplers. 1.10 Users of this guide s
