Introduction
Background of Standard Revision and Technological Evolution
GB/T 17001.2-2025 "Anti-counterfeiting Inks Part 2: Magnetic Anti-counterfeiting Inks" as the replacement version of GB/T 18751-2002, reflects the continuous improvement and technological progress of China's anti-counterfeiting technical standards. This revision not only adjusted the standard numbering system, but also made important updates to the technical content, reflecting the technological development achievements in the field of magnetic anti-counterfeiting inks over the past 20 years.
Standard Framework and Core Changes
Compared with the 2002 version, the new version of the standard has been significantly optimized in terms of structure and technical requirements:
| Comparison Dimensions | GB/T 18751-2002 | GB/T 17001.2-2025 | Description of changes |
|---|---|---|---|
| Classification system | Single classification | Soft magnetic/hard magnetic dichotomy | Add scientific classification basis |
| Product model | With model compilation method | Delete this chapter | Simplify the standard structure |
| Technical requirements | Basic requirements | Add general requirements + anti-counterfeiting features | Requirements are more systematic |
| Detection method | Brief description | Detailed instrument method and calculation formula | Improve detection operability |
| Quality control | No inspection rules | New Chapter 7 Inspection Rules | Improve quality management system |
Detailed explanation of the technical classification of magnetic anti-counterfeiting inks
Chapter 4 of the standard clarifies the classification method based on coercive force:
Soft magnetic anti-counterfeiting ink: It uses low coercive magnetic powder material (Hc ≤ 1000A/m), which has the characteristics of easy magnetization and easy demagnetization, and is suitable for scenarios that require rapid identification and verification.
Hard Magnetic Anti-Counterfeiting Ink: Made of high-coercivity magnetic powder material (Hc > 1000A/m), it has high remanence properties and is suitable for applications requiring durable anti-counterfeiting features.
Technical Requirements and Performance Index Analysis
General Requirements
Standard Table 1 specifies the basic performance indicators of different types of inks, including key parameters such as appearance color, tinting strength, fineness, fluidity, viscosity, initial drying, adhesion fastness, and surface tension.
Anti-Counterfeiting Feature Requirements
| Performance parameters | Hard magnetic anti-counterfeiting ink | Soft magnetic anti-counterfeiting ink | Test method |
|---|---|---|---|
| Relative deviation of coercivity | ≤10% | ≤10% | Vibrating sample magnetometer |
| Relative residual Residual magnetization intensity 100±10% - Formula (1) Calculation Relative magnetic susceptibility - 100±10% Formula (2) Calculation Test method and instrument requirements Chapter 6 of the standard specifies the test method for magnetic properties in detail. The core is to use a vibrating sample magnetometer for measurement: Equipment requirements: The relative error of the instrument's comprehensive accuracy is no more than 3%, and the balance reading accuracy is ±0.1mg. The vibrating sample magnetometer must include complete components such as magnets, power supply, vibration head, and detection coil. Environmental requirements: The test room must be free of strong electromagnetic interference, with a temperature of 15-30°C and a relative humidity of less than 75%. Test steps: Including standardized processes such as sample preparation, parameter setting, and automatic measurement to ensure the comparability and accuracy of test results. Implementation and application recommendationsKey points for implementation by manufacturers1. Organize production strictly according to classification requirements and clearly define whether the product belongs to soft magnetic or hard magnetic type 2. Establish a comprehensive quality control system, especially for the screening and inspection of magnetic powder materials 3. Equip with necessary testing equipment, especially specialized instruments such as vibrating sample magnetometers 4. Standardize product labeling and packaging to ensure compliance with the requirements of Chapter 8 Purchasing Guide for Users1. Select the appropriate type of magnetic anti-counterfeiting ink based on the application scenario 2. Require suppliers to provide product test reports that comply with the new standard 3. Focus on verifying key parameters such as coercivity and residual magnetization 4. Establish a warehousing inspection system to ensure the stability of ink quality Significance of standard implementation and industry impactGB/T The implementation of GB/T 17001.2-2025 will have a profound impact on the anti-counterfeiting industry: First, unified technical requirements and testing methods will regulate market competition and eliminate non-compliant products and companies. Second, clear classifications and technical indicators provide a clear direction for product research and development, promoting technological innovation and industrial upgrading. Finally, comprehensive inspection rules and packaging and transportation requirements will help improve the quality management level of the entire supply chain. This standard, together with other parts of the GB/T 17001 series, constitutes a complete anti-counterfeiting ink standard system, providing solid technical support for the healthy development of anti-counterfeiting technology.
