1 Scope

1.1 Overview This section GB/T 17421 specifies the fixed workplace noise test method and its associated tools assist device on the ground. Measurement The purpose is to test the measured noise emission data of the machine. The measured data can be used to declare and verify the machine's noise emission ISO 4871 requirements. In accordance with the provisions of the environmental conditions, installation and Working conditions, it can also be used to compare the performance of different units of the same type of machine or device. Connection with a number of machine tools, and focus auxiliary devices operating together emitted noise should be considered as background noise. This section of "auxiliary device Set "refers to a hydraulic power boxes, chip conveyor, coolant oil mist separation means, heat exchange means, cooling means and so on. This section gives a test machine installation, general instructions to run, work location and other designated location measurement microphone position. Equipment Noise test body may be specified in the relevant test various types of machine tools. This section in Chapter 11 provides the noise level is measured in the vicinity of the position of methodological work tools and other designated location, the method adopted The ISO 11202 and ISO 11204 method specified. Chapter 12 This section sets out on an imaginary envelope surface measuring machines measure the SPL, and calculates that the machine sound power level party , The method using the method ISO 3744 and ISO 3746 requirements. This section does not involve the use of sound intensity method (see GB/T 16404 and GB/T 16404.2) measured sound power level. 1.2 Types of noise and noise sources The method specified in this part for measuring a variety of machine noise emission. This section applies to a variety of types and specifications of the machine, including equipment, parts and components. Note. in this section may not be measured or ultra-long machine, such as automatic line. 1.3 Test Environment This part of the test environment is generally. a plurality of indoor or reflective surfaces, and to meet this part of the provisions of 11.4.2 and 12.3.2 Requirements. 1.4 accuracy class Test a specified location in accordance with the provisions of this part of the method of sound power level and sound pressure level value of a machine is likely not the true value Same, the difference should be within the range specified measurement uncertainty. Noise level measuring sound power level measurement uncertainty is due to several Factors affecting the test results caused by environmental conditions, some of which is related to the test sites, and other measurement technologies. The method of testing according to the noise level and sound power level specified in this part, the results should meet the Class 2 accuracy (engineering method) and 3 fine Degree (simple method). Because of the higher Class 2 accuracy, it should be possible to reach level 2. Chapter 7 gives special information measurement uncertainty. Although Class 2 accuracy (engineering method) higher, but grade 3 accuracy (simple method) can meet the requirements of noise declaration and other purposes. This section only A complete description of the measurement accuracy of three. For precision measurement level 2, but also the use of ISO 3744 and ISO 11204 regulations.
