This Standard specifies the method for measuring the distribution temperature or the colour temperature of radiation in the visible wavelength range from an incandescent lamp (including a tungsten halogen lamp) of which the bulb has low wavelength selective absorption and reflection, and the method for measuring the correlated colour temperature of radiation of the light source of which the light source colour is almost achromatic.
