Lamp holder gauge, PGJ21t lamp holder gauge, PX23t lamp holder gauge, PGJX28 lamp holder gauge, PU43t lamp holder gauge Requirements for lamp holder gauges, PGZ12 lamp holder gauges, PG18.5d lamp holder gauges, and PGJ(X)50 lamp holder gauges (see 6.3);

---Changed the gauges for P23t lamp holders (GA), PX26, and PY26d-1~PY26d-7 lamp holders and sockets; and modified the inspection gauges for P43t and PX43t.

The minimum stop gauge for lamp holder size M and the maximum value of lamp holder size Y for P43t, PX43t, PY43d, and PZ43t lamp holders.

Requirements for gauges (see 6.3, Chapter 6 of the 2008 edition).

This document is modified to adopt IEC 60061-3:2005 "Lamp holders, lamp bases and gauges for testing their safety and interchangeability - Part 3: Gauges".

---Added Chapter 1 "Scope", Chapter 2 "Normative References", Chapter 3 "Terms and Definitions", and Chapter 4 "Product Classification and Subscriptions".

"Number" and Chapter 5 "Markings and Packaging".

The technical differences between this document and IEC 60061-3:2005, and the reasons therefor, are as follows.

---This document retains only the gauging requirements for prefocused lamp holders and sockets from IEC 60061-3:2005, and has removed requirements for other types of lamps.

The gauge requirements for the head and lamp holder should meet the structural specifications of the sub-section of GB/T 1483;

---Added normative references to GB/T 1406.3, GB/T 1483.1, GB/T 1957, and GB/T 19148.3 (see 6.3) to conform to...

It conforms to my country's standard drafting regulations.

The following editorial changes have been made to this document.

---To align with existing standards, the standard name has been changed to "Inspection Specifications for Lamp Holders and Lamp Bases Part 3: Prefocusing Lamp Holders and Lamp Bases".

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.

---Part 3: Gauges for Prefocused Lamp Holders and Bases. The purpose is to specify the dimensions for inspecting the interchangeability of prefocused lamp holders and bases.

---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 1483.3-2008 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 pre-focused lamp holders and sockets, and adds requirements for various lamp models.

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

They all have very important significance.
