This standard refers to the use of the international standard IEC 400 (1987) "tubular fluorescent lamp holder and starter seat".
1 Subject content and scope of application
This standard specifies the technical requirements, test methods and inspection rules for tubular fluorescent lamp holders and starter seats (hereinafter referred to as lamp holders and bases, respectively). It is used to ensure the safety and interchangeability of the fluorescent lamp and the starter in the seat.
This standard is applicable to the lamp holder and the seat with protection class IP20 (the seat above the protection class should refer to the relevant test of GB7001), and it is used in places without dripping, dust-free and non-corrosive gas.
This standard applies to the lamp holder and the seat included in GB 13260. Other types of seats should also be used as reference.

3 terms
3.1 Elastic lamp holder: A pair of lamp holders fixedly mounted in the lighting device. The contact position of one or two lamp holders can be moved axially to compensate for the change of the length of the lamp tube and facilitate the loading and unloading of the lamp.
3.2 Inelastic lamp holders (also known as rigid lamp holders): A pair of mounting positions are fixed and do not rely on the movement of the contacts to compensate for changes in the length of the lamp or to mount the lamp holder.
3.3 Built-in lamp holder or stand: A seat specially designed for mounting inside the lamp.
3.4 Unprotected lamp holder or stand: Use additional means to provide a seat for protection against electric shock.
3.5 Stand-alone lamp holder or stand: A lamp holder or a stand that can be separated from the lighting device and can meet the necessary protection against electric shock.
4 Electrical parameter rating and maximum operating temperature
4.1 AC voltage RMS: no less than 125V for G 5 sockets, no higher than 250V; no less than 125V for other models, no higher than 1000V.
4.2 Current value: not less than 1A for G5 and G23 sockets; not less than 2A for other models.
4.3 Maximum working temperature: no more than 50 °C for G5 lamp holder; no more than 110 °C for G23 lamp holder; no more than 80 °C for other lamp holders.
5 Technical requirements
5.1 Protection against electric shock
5.1.1 When the lamp holder and the base are installed and used under normal conditions, the live parts of the seat should not be touched.
5.1.2 When the seat is in the normal installation position, when inserting or removing the lamp or starter, prevent only one lamp foot or contact from being inserted and the other lamp pin or contact exposed.
For the G5, G13, and G10q lamp holders, electric shock should be prevented within a range of 5° from the normal position when the lamp is inserted.
5.1.3 Anti-shock components should be firm and reliable, should not be loose during normal use, and cannot be dismantled by hand.
5.1.4 The exposed surface of the lamp holder and the anti-shock component of the seat is made of insulating material. Wood, cotton, silk and paper, etc., should not be used as insulation materials without proper impregnation.
5.2.1 Lampholders and Sockets Use a screw terminal or solder lug to connect the power cord.
5.2.2 Threaded posts shall be sufficiently connectable to conductors of 0.5 to 1.5 mm2 nominal cross-sectional area.
5.2.3 Terminals shall not be made of soft materials such as zinc or aluminum. The current-carrying member must be made of copper or a copper alloy containing not less than 50% copper.
5.2.4 Threaded posts shall be such that the conductors are reliably pressed between the metal surfaces. The solder lug should be soldered firmly to the wire. The wire to the terminal should be able to withstand a tensile force of 50N for 1 min without moving.
5.3 Structure and size
5.3.1 The seat shall have the contact contact force specified in this clause. The size of the seat used to ensure interchangeability shall comply with the provisions of GB 13260.
5.3.1.1 For a lamp, a rigid lamp holder that is mounted from the side and rotated 90°:
The torque required to insert the gauge into the lamp holder and turn it to the desired position does not exceed 0.3 N·m for the G5 socket; it does not exceed 0.5 N·m for the G13 socket.
The torque required to remove the gauge from the normal mounting position is 0.02 to 0.3 N·m for the G5 socket and 0.1 to 0.5 N·m for the G13 socket.
