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). Please note that some of the contents of this document may involve patents.

1 Scope

GB/T 15040-2021 is the Chinese national standard on working standard lamps for the measurement of luminous flux, in the field of electrical engineering. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 26 November 2021 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 June 2022. Classification: ICS 29.140.99, CCS K71. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

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.
