Foreword

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

This document replaces GB/T 24461-2009 "Technical Requirements for Lamps for Clean Rooms": Compared with GB/T 24461-2009, except for structural adjustments in addition to general and editorial changes, the main technical changes are as follows:

a) Modified the scope of application of the standard (see Chapter 1, Chapter 1 of the:2009 edition);

b) Added five terms and definitions: "transient light artifact", "fluctuation depth", "flicker", "stroboscopic effect" and "lumen maintenance life" (see 3.6~ 3:10), the definitions of the four terms "clean room", "clean area", "cleanliness" and "clean room lamps" have been changed (see 3.1, 3:2, 3:4, 3:5,:2009 version 4:1, 4:2, 4:4, 4:5);

c) Deleted the classification of lamps (see Chapter 5 of the:2009 edition), creepage distances and clearances (see Chapter 8 of the:2009 edition), and grounding regulations (see Chapter 9 of the:2009 edition), terminal blocks (see Chapter 10 of the:2009 edition), external wiring and internal wiring (see Chapter 11 of the:2009 edition), protection against electric shock (see Chapter 12 of the:2009 edition), durability test and thermal test (see Chapter 12 of the:2009 edition) Chapter 13 of the:2009 edition), dust protection, against solid foreign objects and water resistance (see Chapter 14 of the:2009 edition), insulation resistance and electrical strength (see Chapter 15 of the:2009 edition), heat resistance, fire resistance and marking resistance (see Chapter 16 of the:2009 edition);

d) Changed the general requirements (see Chapter 4, Chapter 3 of the:2009 edition);

e) Changed the relevant requirements for marking (see 5.1, Chapter 6 of the:2009 edition);

f) Changed the relevant requirements for structure (see 5.2, Chapter 7 of the:2009 edition);

g) Added requirements and test methods for luminous flux maintenance life (see 5.3 and 6:3);

h) Added requirements and test methods for electromagnetic compatibility (see 5.4 and 6:4);

i) Added requirements and test methods for transient optical artifacts (see 5.5 and 6:5);

j) Added brightness limit requirements and test methods (see 5.6, 6:6):
