This standard specifies methods for measurement and characterization of indoor environment parameters to assess their corrosion to metals and alloys. Unlike the outdoor environment, the types and concentrations of pollutants in the indoor atmosphere can be more complex, so specific Measuring methods are required. This document covers how to measure environmental parameters, including air pollutants, and updates the relevant technical requirements and normative citation documents. Major changes include updating the relevant literature citation and detection limit standards, adding new content to improve the accuracy of measurement. The standard provides a scientific basis for assessing and managing indoor environment corrosion risks.
