Lamp caps and holders together with gauges for the control of interchangeability and safety. Part 2 : Lampholders.

This document outlines the technical specifications and measurement tools designed for lamp holders, focusing specifically on their interchangeability and safety characteristics. It serves as a reference for defining the precise dimensions and tolerances required to ensure that light bulb bases fit securely into their corresponding sockets. The content covers the design criteria for various types of holders used in electrical lighting systems, aiming to prevent mechanical incompatibilities or hazardous conditions arising from improper fit. Detailed geometric requirements and testing methodologies are provided to verify that components meet the necessary standards for safe installation and reliable electrical contact. The document is structured to assist manufacturers, inspectors, and regulatory bodies in evaluating whether lamp holders conform to the established dimensional profiles. By adhering to these defined parameters, the risk of loose connections, overheating, or physical damage during operation is significantly reduced. This specification plays a crucial role in maintaining uniformity across different lighting products and ensuring compatibility in diverse electrical environments without referencing specific organizational names or release dates.
