Область применения

This standard applies to the Regional flag of Hong Kong special administrative region made from various materials. It specifically covers flags made of chemical fiber fabrics (excluding man-made fibers) and silk, as well as those made of cotton, wool, and linen. Manufacturers of paper and plastic flags must also refer to this standard for appearance quality control. It is not applicable to non-official or commemorative flag designs that deviate from the prescribed pattern.

Технические требования

This standard specifies the mandatory physical and chemical requirements for the regional flag. It defines the exact shape and pattern of the flag, including the dynamic Bauhinia flower design and five-star placement. The standard outlines standard dimensions and allowable errors for 8 specific flag sizes, ranging from No. 1 flags to car and table flags. Manufacturers must strictly adhere to these proportional dimensions and tolerances. The document details the requirements for fabric materials, referencing GB/T 17392 for fabric quality. It sets strict color standards and allowable errors for the red flag face, red stars, and white Bauhinia petals, aligning the red hue with the national flag color standard samples as per GB 12983. Furthermore, it specifies the color fastness requirements for different materials, including light, weather, and washing fastness. The standard also mandates specific sewing techniques, such as double-line stitching for edges and precise stitching density, while prohibiting splice seams on the flag face. Strict appearance evaluation criteria are enforced to prevent any stains, color bleeding, or unclear contours.

Методы испытаний

Testing procedures include fabric quality assessment per GB/T 17932, and color difference evaluation using the grey scale card method in GB/T 250. The stimulus value Y10 for the white petals is measured via colorimetry according to GB/T 3979. Color fastness is tested for light, weather, and washing resistance using methods like GB/T 8427 and GB/T 3921. Dimensional measurements require instruments with an accuracy of at least 0.5%, and visual appearance evaluation must be conducted under specific natural or fluorescent lighting conditions at a distance of 1m to 1.2m. Each flag must pass a 100% visual inspection before leaving the factory.
