1.Structure and Drafting Rules of Standardization Documents" Drafting. This document replaces GB/T 15039-1994 "Luminous Intensity, Total Luminous Flux Standard Bulbs", which is mainly compared with GB/T 15039-1994 The technical changes are as follows:

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

---Added the grading requirements and general requirements of luminous intensity standard lamps and total luminous flux standard lamps (see Chapter 4 and Chapter 5);

---Added the technical requirements and test methods for the angle characteristics of the luminous intensity standard lamp (see 6.4, 8.4).

1 Scope

GB/T 15039-2021 is the Chinese national standard on standard lamps of luminous intensity and total 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 specifies luminous intensity standard lamps and total luminous flux standard lamps (hereinafter referred to as "standard lamps" or "lamps" when it will not cause misunderstanding) Classification, grading requirements, general requirements, technical requirements and test methods, and provide information on common types of incandescent lamps and halogen lamps Sexual information. This document applies to incandescent lamps, halogen tungsten lamps and LED standard lamps that maintain and transmit light measurement values. Other types of standard lamps such as If necessary, you can also refer to this document.
