Scope

This verification system table is suitable for the verification of low-light photometric measuring instruments. It specifies the use of the national reference standard for low-light photometric units, lux (lx), the full set of basic measuring instruments included in the reference standard, the basic metrological parameters of the reference standard, and the procedure for transferring the value of low-light photometric units from the reference standard to working measuring instruments, and indicates their uncertainty, tolerance, and basic verification methods.
To ensure the uniformity and continuity of low-light photometric values and high-light photometric values, the measurement range of the bright vision low-light photometric system connects with the measurement range of high-light levels over a wide range.
