The horse's body is soft and hard, and feels comfortable; the whole body is uniform and smooth, the inner and outer tubes are properly tight, and the movable parts are flexible to use. The corrosion resistance level is not less than level 7
a. The leather surface has uniform color, and knife wounds, snake eyes, and injuries are not allowed
b. The spray paint or baking paint has a clear color, without paint streaks, wrinkles and dirty spots. The saddle ring must be firm and not shake. It must be perpendicular to the horse body and interchangeable. The main dimensions are shown in Figure 245. The corrosion resistance level must not be lower than level 5. The color of the artificial leather surface must be uniform and without damage. The paint color must be uniform and uniform, without paint streaks or exposed bottom. 070. 3 Test method. GB8394-87. 3.1 Specifications and dimensions must be measured with a vernier caliper, steel tape measure or special ruler with the same indication error. 3.2 Stability: Place the saddle horse on the reference plane and push it by hand without swaying or shaking. 3.3 Softness and hardness: Determine by hand feel. 3.4 The corrosion resistance of the electroplating layer must be tested for 24 hours according to GB5938 "Neutral Salt Spray Test (NSS) Method for Corrosion Resistance of Metal Coatings and Chemically Treated Layers of Light Industrial Products", and rated according to GB5944 "Evaluation of Corrosion Test Results of Metal Coatings of Light Industrial Products". 3.5 Compatibility is measured by hand feel.
3.6 Surface quality is checked visually or by comparison with actual samples. 3.7 Interchangeability The saddle ring is firm and does not shake, which is measured by hand feel. 4 Inspection rules
