GB/T 9468-2008General requirements for the photometry and goniophotometry of luminaries (English PDF)

Foreword

The standard reference CIE121-1996 "luminaire photometry and photometric distribution." This standard replaces GB/T 9467-1988 "indoor lighting photometric test" and GB/T 9468-1988 "road lighting photometric test Test "This standard GB/T 9467-1988 and GB/T 9468-1988 The main differences are as follows.

--- Increased use of integral photometric luminous flux measurement method (5.3.3 in this edition).

--- Increasing the brightness measurement method (edition 5.5).

--- Increasing the measurement of illuminance (edition 5.6).

--- Increased uncertainty evaluation (edition 6.2).

--- Increased schematic A, B, C plane system (Figure A.1 ~ edition in Figure A.3) coordinate system in the luminaire photometry chapter.

--- Increase the relationship between A, B and C-plane system (this standard A.4.4).

--- Increased schematic diagram (Fig edition in C.1, Figure C.2) determine lamps and light source photometric center.

--- Increased sophistication and stability with respect to single-ended compact fluorescent lamps made before the photometric test methods and requirements (in this edition C. 1.3.2.4).

--- Introduces the concept of service conversion factor (in this edition of D.3).

The Standard Appendix A, Appendix B, Appendix C, Appendix D are normative appendix. The standard proposed by China National Light Industry Council.

1 Scope

This standard specifies the standard conditions photometric tests, and recommended testing procedures, as well as laboratory tests and luminaire photometric performance data Expression guidance. For the actual test conditions differ from the standard test conditions of lighting, standard measurement requirements are given correction coefficient.

This standard applies to most types of lamps photometric test. As a special type of highly specialized facilities lighting design, measurement and number According expressing with special needs, this standard does not cover its properties, should use additional criteria. These complementary standards within the appropriate standard clauses cited Use, and define specific requirements and measurement conditions when necessary.
