Foreword
This standard is based on the rules of GB/T 1.1-2009 and GB/T 20000.2-2009.
This standard uses the re-drafting method to modify the use of CIE105-1993 "pulsed light radiation source spectral radiation measurement method".
This standard has more structural adjustment compared with CIE105-1993, Appendix A lists the standard and CIE105-1993
Chapter control list.
There are technical differences between this standard and CIE105-1993, and the terms involved in these differences have passed through the blank space
(│), and a list of the corresponding technical differences and their causes is given in Appendix B.
This standard is proposed by the China Light Industry Federation.
This standard by the National Lighting Standardization Technical Committee of light radiation measurement sub-technical committee (SAC/TC224/SC3) centralized.

Introduction
Pulse light source is widely used in a variety of fields and a variety of equipment, such as LED, the camera's electronic flash unit, aircraft and emergency
Through the signal lights, photocopiers, colorimeter and pulse light display. And pulse LED light source has begun large-scale application to the camera
Electronic flash unit, signal lights and other fields, it is also the future development trend. Thus, the transient spectral characteristics of the pulsed light source are measured
The growing demand for the industry, the industry urgently need the relevant standards to regulate the measurement of pulsed light sources.
This standard is intended to standardize the measurement of the transient spectral characteristics of pulsed light radiation sources. As the field of measurement changes and innovation is very rapid,
Especially in the detector and instrumentation technology, so this standard emphasizes the measurement method rather than the specific instrument technology. This standard is in the Appendix
F enumerates an operable method of measuring the pulse LED light source, but does not mean that the method is the only way to achieve satisfactory results.
This standard applies to a variety of types of pulsed optical radiation measurements, such as.
--- steady-state light radiation with shutter;
--- steady-state light radiation with switching circuit [such as flash incandescent or light-emitting diode (LED)];
- directional steady-state light radiation about a shaft that is perpendicular to the optical axis;
A single or repetitive pulsed light radiation produced by the discharge of xenon or other gas mixtures.
Since pulsed laser radiation has coherent and narrowband characteristics, special measurement techniques are required, so this standard does not involve pulsed laser radiation
Measurement.
