GB 15040-1994Working standard lamps for the measurement of luminous flux (English PDF)

Foreword

This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for Standardization Work Part 1: Structure and Drafting Rules of Standardization Documents" Drafting.

This document replaces GB/T 15040-1994 "Standard Light Bulbs for Ordinary Metering". Compared with GB/T 15040-1994, except for structural adjustment and compilation in addition to the editorial changes, the main technical changes are as follows.

---Modified the scope of application of the standard, stipulating that standard lamps include incandescent lamps, tungsten halogen lamps and LED lamps (see Chapter 1, 1994 Chapter 1 of the Year Edition);

---Modified the product classification (see Chapter 4, Chapter 4 of the 1994 edition);

---The general requirements for working test lights have been added (see Chapter 5);

---Added specific requirements for power supply and test equipment for testing (see 7.2).

1 Scope

This document stipulates the classification, general requirements, Technical requirements and test methods, and provides information about common models of incandescent lamps and tungsten halogen lamps for working light metering standard lamps.

This document is applicable to incandescent lamps, tungsten halogen lamps and LED standard lamps used as standard light sources when measuring luminous flux.

If necessary, standard lamps can also refer to this document.
