1 Scope

This standard applies to illuminance meters and luminance meters. This standard defines the quality of the performance characterization of the above equipment used in general lighting measurement

Indicators, as well as the measurement process and standard calibration procedures of each indicator.

The measurement of illuminance and brightness and its accuracy are affected by many factors, such as operating conditions, light source characteristics and the characteristics of the photometer used.

For a specific measurement task, the measurement uncertainty cannot be estimated based on the characteristics of the photometer alone. However, in most cases, sex

Equipment with better performance has less measurement uncertainty than equipment with poor performance. This standard aims to.

--- Provide clear and clear definitions for each quality index;

---Specify the measurement steps and methods for quantitatively evaluating these quality indicators;

---Specify the calibration conditions of the illuminance meter and the luminance meter.
