Compliance overview
Scope and applicability
This standard specifies the technical requirements, 3D digital models, inspection rules, and packaging for the National Emblem of the People's Republic of China. It applies specifically to physical emblems designed for hanging. It is mandatory for all manufacturers producing suspended national emblems. Additionally, flat emblem patterns made by printing or other processes may refer to this standard for execution.
Technical requirements
This standard outlines the physical and structural requirements for the national emblem, including precise dimensional tolerances for standard sizes (No. 1, No. 2, and No. 3). It defines the acceptable limits for flatness and roundness of the emblem face and base. The standard also specifies the exact color parameters for emblem red and emblem gold using the CIEXYZ color space and the Chinese color system. Furthermore, it sets performance criteria for the surface paint film, including gloss, adhesion, hardness, and resistance to weather, water, humidity, and salt spray. The emblem body must be made of compliant materials like fiber-reinforced plastics or aluminum alloys, meeting minimum thresholds for bending strength and Barcol hardness. Manufacturers must also adhere to the newly introduced 3D digital model specifications for spatial structure and geometric details.
Testing methods
Testing involves visual inspection under natural light or simulated D65 light sources to assess surface appearance and component quantities. Dimensional verification can be conducted using traditional measuring tools or digital technology (e.g., 3D scanners). Material and coating performance tests follow referenced GB/T standards, including the ball drop impact test for structural integrity and various standardized methods for paint film adhesion, hardness, and environmental aging resistance.
FAQs
What products are regulated under GB 15093-2025?
This standard applies to the manufacturing of physical, suspended National Emblems of the PRC. It is mandatory for all manufacturers producing these specific national symbols. Additionally, flat printed or processed emblem patterns may refer to this standard for guidance.
Are there any updates from the previous version of GB 15093?
The 2025 revision updates the emblem's shape and pattern to align with the 2021 National Emblem Law. It introduces a 3D digital model, adds a longitudinal section drawing, updates terminology (e.g., changing "emblem yellow" to emblem gold), and integrates color parameters with the Chinese color system.
How does GB 15093-2025 differ from international standards?
While it does not directly adopt ISO standards, it references equivalent Chinese national test methods (GB/T series) for material properties and colorimetry, which are largely aligned with international testing methodologies such as ISO for paints, coatings, and plastics.
