Compliance overview
Scope and applicability
This standard applies to the regional flag of Macao Special Administrative Region made from chemical fiber fabrics (excluding artificial fibers), silk, cotton, wool, and linen. It is also applicable as a reference for the appearance quality control of flags made from paper or plastic. It establishes the mandatory technical baseline for manufacturers producing official regional flags.
Technical requirements
The standard specifies the physical and chemical requirements for the Macao SAR flag, including precise shape, pattern symmetry, and standard dimensions across various flag sizes (No. 1 to No. 5, vehicle flags, signing flags, and table flags). It defines strict chromaticity coordinates and stimulus values for the flag's green background and the specific "Lotus White". Additionally, it mandates color fastness grades for resistance to artificial light, artificial weather, and washing, tailored to different fabric types. Manufacturers must adhere to these exact dimensional tolerances and colorimetric parameters to ensure compliance. The standard also details strict sewing requirements, such as prohibiting splice seams on the flag face and specifying exact stitching density.
Testing methods
Testing involves colorimetric measurements using methods specified in GB/T 3979 to verify the stimulus values of the green and white elements. Color fastness is evaluated against GB/T 8427 and GB/T 8430 for light and weather resistance, respectively. Dimensional verification requires measuring tools with an accuracy of no less than 0.5%. Visual appearance assessments must be conducted under specific natural or fluorescent lighting conditions at a defined distance.
