1. SCOPE

1.1 This standard (Part 2) specifies the performance requirements and test including standard lamp data sheets for double-capped fluorescent lamps, commonly known as tubular fluorescent lamps for general lighting service. Lamps of the following types are covered in this standard:

a) Lamps with preheated cathodes for operation on a.c. mains with or without the use of starter;

b) Lamps with preheated cathodes for operation on high frequency with or without the use of starter; and

c) Lamps with non-preheated cathodes for operation on high frequency supplies without the use of starter.

1.2 It may be expected that lamps which comply with this standard, when operated with a starter complying with IS 2215 and with ballasts complying with IS 1534 (Parts 1) or IS 13021 (Parts 1 and 2) shall start andoperate at voltages between 92 percent and 106 percent of rated supply voltage and for any ambient temperatures between 10° C and 50°C.

1.3 A lamp, on which compliance with this standard is claimed, shall comply with the safety requirements of IS 2418 (Part 1).

1.4 For some of the requirements given in this standard, reference is made to “the relevant lamp data sheet”. For some lamps, these data sheets are contained in this standard. For other lamps, falling under the scope of this standard, the relevant data are supplied by the lamp manufacturer or responsible vendor.
