Introduction

As important components of lamp accessories, lamp holders and sockets require interchangeability and safety as fundamental requirements for safe production.

Gauges are measuring tools used to inspect the dimensions of lamp holders and sockets, and are important inspection instruments to ensure the safety and interchangeability of lamp holders and sockets. GB/T 1483 the "Inspection Gauge for Lamp Holders and Lamp Bases" aims to standardize the gauges for inspecting the interchangeability of lamp holders and lamp bases, and is proposed to include the following five parts.

---Part 1: Gauges for Screw-in Lamp Holders and Bases. The purpose is to specify the dimensional and safety specifications for inspecting the interchangeability of screw-in lamp holders and bases.

Sexual metric.

---Part 2: Gauges for Plug-in Lamp Holders and Recesses. The purpose is to specify the dimensions and safety specifications for inspecting the interchangeability of plug-in lamp holders and recesses.

Sexual metric.

Safety gauges.

---Part 4: Gauges for Miscellaneous Lamp Holders and Bases. The purpose is to specify the dimensional specifications for inspecting the interchangeability and safety of miscellaneous lamp holders and bases.

Gauges.

---Part 5: Gauges for Bayonet Lamp Holders and Bases. The purpose is to specify the dimensions and safety specifications for inspecting the interchangeability of bayonet lamp holders and bases.

Sexual metric.

GB/T 1483.2-2008 has been published for over ten years, and the inspection gauges for lamp holders and sockets in it are no longer compatible with the current mutual requirements of lamp holders and sockets.

Replaceability and safety requirements. This revision updates the technical requirements for inspection gauges of plug-in lamp holders and sockets, and adds several different types of lamp holders.

The inspection specifications for lamp holders are crucial for improving product safety and quality, regulating the market, and enhancing the competitiveness of Chinese products.

It has very important significance.
