1 Scope
This Regulation applies to initial verification, subsequent verification and in-use
inspection for standard-level, level-1 and level-2 ultraviolet radiometers that comply
with the division of ultraviolet radiation UV-A, UV-B, UV-C, UV-A1, UV-365, UV-310,
UV-254 bands.
2 Overview
The International Commission on Illumination (CIE) divides ultraviolet radiation into
three bands. UV-A (315nm~400nm), UV-B (280nm~315nm) and UV-C
(100nm~280nm). Since ultraviolet radiation of 100nm~200nm is strongly absorbed in
the air, for the UV-C band, this Regulation only considers the wavelength range of
200nm~280nm.
3 Metrology performance requirements
3.1 Spectral response and band division
3.2 Zero-value error (full scale FS)
The zero-value error (FS) of ultraviolet radiometers shall not exceed the requirements
of Table 1.
3.3 Long-wave response error
The long-wave response error of the ultraviolet radiometer shall not exceed the
requirements of Table 2.
3.4 Cosine characteristic (directional response) error
The cosine characteristics (directional response) of the ultraviolet radiometer shall not
exceed the requirements of Table 3.
4 General technical requirements
4.1 Appearance
4.1.1 The nameplate of the ultraviolet radiometer shall be marked with the trademark,
model, product number, date of manufacture and CMC logo. The power supply used
and the safety protection during operation shall be given accurate and eye-catching
descriptive markings.
4.2 Optical attenuator
If the ultraviolet radiometer is equipped with a light attenuator, the light attenuator shall
be intact and the attenuation rate shall be marked.
4.3 Spectral response range
The spectral response range of the ultraviolet radiometer shall comply with the
provisions of 3.1.
5 Measuring instrument control
Measuring instrument control includes initial verification, subsequent verification and
in-use inspection.
5.1 Verification conditions
5.1.1 Equipment for verification
5.1.1.3 Measurement device for comparison of UV radiation illuminance
The reference schematic diagram of the structure of the ultraviolet radiation
illumination comparison measurement device is shown in Figure 2
5.1.2 Environmental conditions
Indoor temperature 23℃±5℃; relative humidity ≤70%.
Shading measures shall be taken indoors to prevent interference from the sun,
incandescent light sources and other light sources.
5.2 Verification items
See Table 8 for the verification items.
5.3.5 Shifting error
The test is performed between two different ranges of the Ultraviolet radiometer.
Ultraviolet radiometers with a single range do not perform this test.
5.3.6 Fatigue error
Install the detector and UV radiation source of the Ultraviolet radiometer on the
measuring device (Figure 2). Adjust the light path according to the requirements for
calibrating the Ultraviolet radiometer. Then cover the detector so that it is not exposed
for 24 h.
5.5 Verification cycle
The verification cycle of UV radiation illuminance meter generally does not exceed one
year.
