Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

This standard replaces JY 116-1982. In addition to editorial changes, the main technical requirements of this standard have changed as follows.

-Improved the requirements of the center contact of the lamp holder, using elastic electrodes instead, and defining the telescopic range;

-Added the requirement that two or more metals, metal coatings and chemical treatment layers should not be selected as contact couples;

-Remove the bayonet and screw sockets, only the screw sockets are retained;

-Removed the description that the light bulb should not shake after the light bulb is screwed into the lamp holder, and after the power is turned on, the beads should glow normally and should not flicker;

-Modified the requirements of the terminal;

-Revised requirements for insulation resistance and electrical strength;

-Revised environmental tests;

-Changed the sampling method for percentage sampling.
