DESCRIPTION

BS ISO 14934-2:2013


This standard BS ISO 14934-2:2013 Fire tests. Calibration and use of heat flux meters is classified in these ICS categories:
  • 13.220.50 Fire-resistance of building materials and elements
  • 13.220.40 Ignitability and burning behaviour of materials and products

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 latter will depend on the design of the heat flux meter, the orientation, local temperature and flow conditions, and on the temperature of the cooling water.
