Water cooled heat flux meters are available for measuring the heat flux in a smoke density chamber. This was first described in a NIST publication (NISTIR 4917) in 1992, and has been permitted as an option for several years for smoke chamber testing to FAA requirements in the FAR. This ballot adds a section to permit this alternate heat flux measurement device, and revises the section on furnace calibration accordingly.
