3 Terms and definitions
The following terms and definitions apply to this document.
Ultraviolet germicidal lamp
A low-pressure mercury vapor discharge lamp using quartz glass or other
through-violet glass that discharges to produce UV radiation mainly of a
wavelength of 253.7 nm, AND the UV radiation can kill bacteria and viruses.
Ozone output efficacy
The ratio of the amount of ozone generated by the lamp which is ignited at
the specified conditions to the power consumed by the lamp within the unit
time, in the unit of g / (kW • h).
Nominal value
The value as indicated on the lamp.
Rated value
The specific value of the lamp under the specified working conditions, the
value and conditions of which are specified in this standard or by the
manufacturer and seller.
Initial readings
The measured start-up characteristics of the lamp prior to its aging and the
UV radiation light, electrical and ozone characteristics measured after 100 h
of aging.
Radiant flux
The power emitted, transmitted or received in the form of radiation, in the
unit of W.
Ultraviolet radiant flux
The ultraviolet radiant flux with the main wavelength of 253.7 nm, in the unit
of W.
The radiant flux dΦe projected onto the surface element containing this
point divided by this surface element area dA, in the unit of μW/cm2.
Ultraviolet radiation luminance
The ultraviolet radiation luminance with the main wavelength of 253.7 nm,
in the unit of μW/cm2.
Radiant efficiency
The ratio of radiant flux emitted by a source to the power consumed by it.
Ultraviolet radiation efficiency
The ratio of the lamp’s initial ultraviolet radiant flux to the actual input power,
expressed as a percentage.
Single-capped ultraviolet germicidal lamp
A single capped lamp equipped with an internal starter or external starter
AND connected to an external circuit.
Self-ballasted ultraviolet germicidal lamp
A lamp that is integrated with a lamp cap, a ballast, and a lamp, which is not
detachable unless otherwise damaging its structure.
Double-capped ultraviolet germicidal lamp
Double capped tubular lamp.
Life (of individual lamp)
The cumulative time from the ignition of a lamp to the point of “burnout” OR
to the point when the lamp UV radiant flux maintenance degrades to the
value as specified in this standard.
Average life (life to 50% failures)
The accumulative time from the point when the lamp UV radiant flux
maintenance reaches to the requirements of this standard AND is able to
continue burn until 50% of lamps reach their individual life.
Ultraviolet radiant flux maintenance
When the lamp ignites under specified conditions, the ratio of the ultraviolet
radiant flux at a particular time during its lifetime to the initial ultraviolet
radiant flux of the lamp, expressed as a percentage.
Reference ballast
Inductive ballasts specially designed for lamps operating at AC power
frequencies or resistive ballasts designed for lamps operating at high
frequencies. It is used as a benchmark for checking other ballasts, selecting
reference lamps, and checking lamps that are normally produced under
their standardized conditions. Basic characteristics of a reference ballast
are as described in the standards on ballasts. The ballast has a stable
voltage/current ratio at rated frequency, AND is relatively immune to current,
temperature, and changes in the surrounding magnetic field.
Calibration current of a reference ballast
The current value based on which the reference ballast is calibrated or
4 Product classifications
4.1 Classification and marking
Lamp can be divided into double-capped lamp (represented by “S”),
single-capped lamp (represented by “D”), and self-ballasted lamp (represented
by “Z”) based on its shape; AND it can be divided into two types in accordance
with the presence of ozone. ozone-contained lamp (represented by “Y”) and
ozone-free lamp (represented by “W”).
4.2 Model naming method
ZW15S26W indicates the diameter 26 mm 15 W double-capped ozone-free
ultraviolet germicidal lamp;
ZW7D12Y indicates the diameter 12 mm 7 W single-capped ozone-contained
ultraviolet germicidal lamp.
5 Technical requirements
The design of the lamp, its structure and its performance shall be such that it is
reliable in normal use AND not dangerous to the user and the surrounding
environment. The bactericidal effect of the lamp is generally checked by
conformity with all the specified tests.
5.1 Safety requirements
The safety requirements of the single-capped lamps, self-ballasted lamps and
double-capped lamps shall comply with the corresponding provision...
