BS 6809:1987

This standard BS 6809:1987 Method for calibration of radiometers for use in fire testing is classified in these ICS categories:

• 17.240 Radiation measurements

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.

General calibration procedure and, in appendices, information on accuracy of calibration, care of radiometers and details of a specific suitable apparatus.
