Introduction

Analysis of the core content of the standard

GA 2122-2023 standard systematically stipulates the technical requirements for the police uniform chest badge, mainly including the following technical dimensions:

Technical category Specific requirements Referenced standards
Material specifications Copper alloy bars/wires, die-cast zinc alloy substrates GB/T 4423, GB/T 21652, GB/T 13818
Surface treatment Coating thickness ≥8μm, corrosion resistance 96h GB/T 6462, QB/T 3826
Coating standards Amino alkyd resin/polyurethane coating GB/T 25249, HG/T 2454

Detailed explanation of key technical indicators

Standard requirementsDress chest badgeThe metal substrate should preferably be H62 copper alloy (GB/T 4423), and the coating bonding strength must pass the QB/T 3821-1999 test:

  • Gold-plated parts must achieve 48 hours of neutral salt spray test without corrosion
  • Paint film adhesion test cross-hatch method ≤ Level 1
  • Dimensional tolerance is controlled within the range of ±0.15mm

Recommendations for the implementation of the standard

Manufacturers should establish a three-level quality control system:

  1. Incoming raw material inspection (copper material composition analysis)
  2. Process control (real-time monitoring of electroplating parameters)
  3. Full inspection of finished products (including X-ray coating thickness measurement)

It is recommended to refer to the color standard sample card provided by the Academy of Fine Arts, Tsinghua University for appearance acceptance.


Background of Standard Evolution

Compared with the old version of the standard, GA 2122-2023 has the following major upgrades:

  • New requirements for packaging of degradable polyethylene films (QB/T 2461)
  • X-ray spectroscopy (GB/T 16921) is used to replace some destructive testing
  • Specify that the compressive strength of transport packaging is ≥8000N
