    Scope - (Show below) - (Hide below)

    This British Standard describes a method for the calibration of radiometers for use in fire testing. This method may be used to calibrate instruments that are used to measure a rate of heat transfer (heat-flux density) due to a combination of radiation and convection (but see Appendix C which gives guidance notes concerning calibration).

    This method applies only to instruments having plane receivers and does not apply to receivers in the form of wires, spheres, etc.

    Appendix A gives information on the accuracy of the calibration and reference should be made to the standard describing the test for which the radiometer is intended. Appendix B gives guidance on care of radiometers.

    NOTE The title of the publication referred to in this standard is given on the inside back cover.
