General item testing methods
5.1 Noise testing
5.1.1 Conduct noise testing in accordance with ZBJ50004. 5.1.2 For large or extra-long testing equipment, the microphone measurement point is specified as the operating position of the equipment, and its height from the ground is 1500mm.
When testing noise, noise sources such as motors and fans should be shielded. 5.1.32
5.1.4 Its requirements should comply with the provisions of JB/DQ8657. 5.2 Appearance quality inspection
Visually inspect the installation and arrangement of pipes and lines for oil, water, gas, electricity, etc. 5.2.1
Use conventional measuring tools to measure the appearance quality of the combination and dislocation between non-machined surfaces, and visually inspect the quality of the exposed machined surfaces and coating surfaces. Use paint film samples to inspect the paint film quality. 5.2.3
5.2.4 The appearance quality requirements shall comply with the provisions of JB/DQ8124.11 and JB/DQ8657. 5.3 Electromechanical safety device inspection
5.3.1 After the equipment is powered on, check that the equipment action should comply with the requirements of the schematic diagram. 5.3.2 The grounding resistance of the metal casing is tested with a 500V megohmmeter. Safety protection facilities should be tested for action 3 to 5 times. 5.3.3
