JIS C 7607:1991 (R2017)

This Japanese Industrial Standard specifies methods for obtaining total luminous fluxes of discharge lamps used for photometric standards using an integrating sphere, from the total luminous flux of the standard photometric discharge lamp of the same kind, by means of relative measurement. This Standard shall be appropriately used for total luminous flux tests of general lighting fluorescent lamp of the same kind, by means of relative measurement. This Standard shall be appropriately used for total luminous flux tests of general lighting fluorescent lamps and high intensity discharge lamps, if nothing interferes.
