I don't understand how the testing machine distinguishes the quality of the testing machine
  1 The appearance of the testing machine should not have irregular bulges, depressions, roughness and other damage.  2 The edges of the separating surface of the parts and components of the testing machine should be uniformly symmetrical, and there should be no obvious misalignment. The door and cover should be easy to load and unload, and the gap between the separating surface should not exceed the rules in the table below.   the largest size gap   ≤500mm 1  >500-1000mm 2  >1000mm 3  3 The countersunk screw should not protrude from the surface of the part, and there should be no obvious eccentricity between the head and the counterbore. The fixing pin should protrude from the surface of the part, and the exposed shaft end should protrude from the end face of the receiving part, and the protruding value is approximately the chamfer value. The end of the bolt should protrude slightly from the nut.  4 The machined surface of the parts of the testing machine shall be free of rust, burrs, bruises, scratches and other defects.  5 The color of the paint of the testing machine should be beautiful and generous, the color should be mild, and the color registration should be harmonious. The boundaries of different colors should be clear and not mutually pollute.  6 The paint and putty of the testing machine should have enough strength to resist oil and corrosion, and there should be no peeling and falling off.  7 The unprocessed appearance of all parts and accessories of the testing machine shall be primed and painted. Before primer painting, rust, sand, oil and other dirt should be carefully removed. The painted surface should be intact, lubricated, even and different in color, and there should be no spots, wrinkles, bubbles, and adhesions.  8 The appearance of electroplated parts should be spotless, and the coating should be even without peeling.  9 The outer color of the blackened parts is uniform, and there is no spot, rust, etc.  10 The various signs on the testing machine should be clear and durable. The nameplate should be fixed in an obvious place. The fixing of the sign should be in the correct position, flat and strong, and not inclined. It is allowed to use artistic factory logos or cast clear Chinese characters on the testing machine.
