Topical Report on a Field Monitoring Study of Homes with Unvented Gas Space Heaters: Volume 4. Quality Assurance/Control Procedures and Results. Final Report January 1985-June 1987

摘要

During the period from January to March 1985, 157 residences in four Texas cities were monitored for pollutant concentrations and use of unvented gas space heaters (UVGSHs) and gas ranges. Average nitrogen dioxide (NO2) and carbon monoxide (CO) concentrations and maximum/minimum indoor temperatures were monitored in all study homes. In selected homes, air infiltration rates and time-varying pollutant concentrations were measured. Characteristics of structures, appliances, and occupants were collected through questionnaires and field technician observations. Quality assurance and control procedures were developed and applied to endure that data of known and acceptable quality would be produced. Such procedures included an external audit, multipoint calibrations, zero and span checks, colocated samples, and other routine activities performed by field technicians.
