3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
ultraviolet lamp
lamp which radiates especially strongly in the ultraviolet, the visible radiation produced,if any,not being of direct interest
[IEV 845-07-52]
fluorescent lamp
discharge lamp of the low-pressure mercury type in which most of the light is emitted by oneor several layers of phosphors excited by the ultraviolet radiation from the discharge
[IEV 845-07-26]
type test
test or a series of tests made on a type test sample for the purpose of checking compliance of the design of a given product with the requirements of the relevant standard
instrument for measuring radiometric quantities in narrow wavelength intervals over a given spectral region
[IEV 845-05-07]
bandwidth at a given wavelength
width at half-amplitude points of the transmittance function of a monochromator (unit: nm)
adjective that, when applied to a quantity X pertaining to electromagnetic radiation, indicates:
– either that X is a function of the wavelength λ , symbol: X( λ );
– or that the quantity referred to is the spectral concentration of X, symbol: X λ = dX/d λ .
X λ is also a function of λ and in order to stress this it may be written X λ ( λ ) without any change of meaning
[IEV 845-01 -1 6]
quotient of the radiant flux d φ e incident on an element of the surface containing the point, by the area dA of that element (unit: W/m 2 )
[IEV 845-01 -37]
