Determination of noise level of woodworking machine tools
GE/T124481990 Woodworking machine tool model comprehensive method 3. Rotation conditions
3.1 The radial reduction of the slices shall not exceed 1.1mm. 3.2 The front 1. The workbench should be adjusted to a cutting depth of 2mm; the guide plate should be placed at the specified width. 2.3.3 The safety device at the door should be correctly positioned. For the adjustable height safety device, it should be adjusted to the position where the test piece with a height of 8Gmm can pass through, but not the test piece with a height of 85m.
3.4 For the flat bed with noise reduction device, the noise reduction device should be specially installed. 4. Measurement method
The measurement type adopts GB3.
5. The limit of noise power level
The flat bed of the first batch is classified according to 12449. The noise output power level of the flat bed of various models and specifications when unloaded shall not exceed the value specified in the following table.
The period of conduction
A weighted output power level La.
