Область применения
This standard is mandatory and specifies the technical requirements, testing methods, and inspection rules for the Regional emblem of Macao special administrative region. It applies specifically to emblems made of fiber-reinforced plastic or aluminum alloy. Additionally, flat emblem patterns made of other materials using printing processes should refer to the relevant requirements of this standard. Manufacturers producing physical emblems for official use must strictly adhere to these specifications.
Технические требования
The standard outlines detailed specifications across several key areas. Firstly, it defines the shape and pattern of the emblem, which must comply with the Basic Law of the Macao Special Administrative Region. It establishes standard dimensions and allowable tolerances for various components, including the emblem face, stars, lotus, bridge, and water patterns, with provisions for proportional scaling for non-standard sizes. Secondly, the standard sets strict colorimetric requirements for the emblem's colors. It specifies the chromaticity values and tolerances for the yellow stars, the green background, and the specific white used for the lotus, bridge, and water. All color data must be calculated using the CIE standard illuminant D65 and the CIE 1964 standard colorimetric system. Thirdly, it mandates specific material strength and coating performance criteria. The emblem body must meet minimum bending strength and Barcol hardness requirements, and withstand drop-ball impact testing without cracking. The paint film on the emblem face must exhibit high gloss, strong adhesion, and resistance to water, humidity, and salt spray. The surface must be free from defects like shrinkage holes, cracks, and deformation.
Методы испытаний
Testing procedures involve precise measurement of dimensions using instruments with an accuracy of at least 0.5%. Colorimetric measurements follow GB/T 3979 and related standards. Paint film properties are tested according to various GB/T standards for adhesion, water resistance, and hardness. Material strength is evaluated through bending tests (GB/T 1449) and Barcol hardness tests (GB/T 3854), alongside a specific drop-ball impact test where a 112g steel ball is dropped from 1 meter. Flatness and out-of-roundness are measured per GB/T 11337 and GB/T 4380, respectively.
