Scope

This document describes the consistency assessment method for RFID readers in animal individual identification with GB/T20563 and GB/T22334. This document specifies the procedures for applying for RFID reader test registration and related rights and obligations. This document covers over-the-air synchronization tests applicable to mobile RFID interrogators; but does not cover the evaluation of wired synchronization for fixed RFID interrogators. The test procedures specified in this document apply to RFID readers used in animal farming.

Introduction

Core requirements of the standard and technical improvements

RFID readers must meet three key improvements: adopt China's self-developed code mechanism (replacing ISO11784/HH-), strengthen tag compatibility detection capabilities (HDX/FDX-B dual-mode), and support enhanced tag identification (RUDI bit verification).

Comparison of consistency assessment frameworks

Test dimensions	International standard ISO246312	Chinese standard GB/T41734.2
Applicable standards	ISO11784/11785	GB/T20563/22334
Tag compatibility requirements	17 types of protocol tags	20 types of compatible tags
Special function items	Single enhanced tag recognition	Dual enhanced mode recognition

Key Technical Indicators of the Test Procedure

Activation Field Timing Detection Specifications

• Startup Response: The startup response must be completed within 1ms when the field strength reaches 80%
• FDX-B mode compatibility: Dynamic adjustment of activation duration (50-100ms)
• Error Suppression: Automatic noise reduction threshold for receiving bit errors ≤-20dB

Key Points for Wireless Synchronization Test Verification

1. Field Strength Test: Strict 100dBμV/m@1m Test Base Point
2. Phase Synchronization: Delay Tolerance ±0.5ms
3. Interference Test: Noise Injection Level Control ±3dB
