New Test Method for Evaluating CO2 Indoor Air Quality Sensors or Sensor Systems Used in Indoor Applications

1. Scope

The promotion of knowledge, the development of test methods, practices, guides, and terminology pertaining to sampling and analysis of atmospheres, interpretation of data, the standardization of recognized and practiced methods for measurement of atmospheric quality, and sponsoring of discussions among those active in the study of air quality.
The work of the Committee will be coordinated with other ASTM Committees and other organizations having mutual interest.


carbon dioxide;


Based on falling costs, consumer-grade CO2 sensors and sensing devices are gaining wide adoption for reporting indoor CO2 concentrations and controlling ventilation systems. Better information is needed with respect to the performance of these sensors so that users can make informed decisions regarding their selection and specification. The primary anticipated users are expected to be IAQ sensor and sensing device manufacturers, smart ventilation system manufacturers, and laboratories. This standard is likely to be referenced in standards and codes that address IAQ in buildings, such as ASHRAE 62.2, ASHRAE 62.1, the International Residential Code, the International Mechanical Code, and California Title 24.

The title and scope are in draft form and are under development within this ASTM Committee.
