Fire tests. Calibration and use of heat flux meters - Primary calibration methods Ingestion-build-53008 What is BS 4971 -1 Scope This part of ISO 14934 describes three methods for calibration of total hemispherical radiometers and total heat flux meters that are exposed to a well defined radiation from a radiant heat source. The equipment is designed to minimize influences due to convective heat transfer during calibration. It is important to note that when the instruments are used in practice they measure a combination of radiant and convective heat transfers. The
