Requirements
Surface pattern is clear, particles are full, and there shall be no shrinkage, thermal cracking, cold cracking, deformation, edge gap, broken edge, and defects such as sand, impurities, and pores that obviously affect the appearance
No obvious stains, color matching, color collapse, etc. are allowed. No obvious stains, color matching, color collapse, etc. are allowed. Must comply with the provisions of 4.4
5.1. The general dimensions and allowable errors of Guowei are measured with steel rulers and square rulers with an accuracy of 1mm. 5.2 Colorimetry measurement shall be carried out in accordance with the provisions of GB11186.2. 5.3 The performance of the emblem surface paint film shall be measured according to the regulations in GB1766, GB9754.GB6739, GB9274, GB1740 and GB1771. 5.4 Strength test:
5.4.1 The bending strength test of glass fiber reinforced plastics shall be carried out in accordance with the provisions of GB1449. 5.4.2 Falling ball impact: Place the national emblem face up, lay it horizontally on the cement floor, place a 112g steel ball 2m above the sample, drop the steel ball freely to the center of the emblem surface, and impact it three times repeatedly. Observe whether there are cracks, delamination, etc. on the surface of the sample. 5.4.3 Drop test: Hang the Guowei sample vertically at a height of 1m from the cement floor, and repeat the free fall twice to observe whether there are cracks, cracks and delamination on the surface.
5.4.4 Measure the hardness of the national emblem made of glass fiber reinforced plastics according to the regulations in GB3854. 5.5 Unevenness test;
Place the national emblem horizontally on a platform or glass plate, measure the gap between the periphery of the national emblem and the plane, and the result is the bottom surface unevenness 6 Inspection Rules
6.1 General dimensions, emblem Surface evaluation, color and other quality inspections are factory inspections. When materials, formulas, and processes change, type inspection should be carried out. Type inspection is a comprehensive inspection of technical requirements. 62 During the factory inspection, if all inspection items of each product are qualified, it will be judged as passing the inspection, and the batch of products will be qualified. Unqualified products are not allowed to leave the factory or circulate in the market. During the type inspection of GB15093-94
, if all inspection items of the product are qualified, it will be judged as qualified and formal production is allowed. 7 logo, packaging
7.1 logo
The manufacturer and serial number are marked on the back of each logo. 7.2 Packaging
7.2.1 Single package must be convenient for transportation and storage. 7.2.2 There should be a certificate of conformity inside the packaging box. The certificate indicates the serial number, date of manufacture, and storage instructions. It also includes the necessary accessories for installation, the name of the manufacturer, the address, and the name (or code) of the inspector. 8 According to the provisions of the "National Emblem Law of the People's Republic of China", the national emblem production factory is designated by the state, and the standardization administrative department of the State Council is responsible for the supervision and implementation.

Instructions for the production of the National Emblem of the People's Republic of China
(General Office of the Central People's Government Committee on September 20, 1950 Announcement), the two wheat jis form a perfect circular ring. The gears are installed at the intersection of the miji poles below. The red ribbons are intertwined with each other and hang down to the left and right, dividing the gears into upper and lower parts. 2. Draw a straight line vertically from the center of the pattern, and the left and right parts of the pattern are completely symmetrical. 3. The position and size of each part of the pattern can be enlarged or reduced according to the proportion of the square ink line drawing. 4. If making a relief, each part should be enlarged or reduced. The height of the parts can be enlarged or reduced according to the proportion of the cross-section diagram. 5. The colors of the national emblem are gold and red: the wheat and rice, the five stars, Tiananmen, and the gear are gold, and the base and hanging ribbon in the ring are red; It is red (the same as the national flag), and the gold is red gold (light and shiny gold)
