The work of preparing International Standar
20、ds is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take
21、 part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. Draft International Standards adopted by
22、the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this part of ISO 230 may be the subject of pate
23、nt rights. ISO shall not be held responsible for identifying any or all such patent rights. International Standard ISO 230-5 was prepared by Technical Committee ISO/TC 39, Machine tools, Subcommittee SC 6, Noise of machine tools. ISO 230 consists of the following parts, under the general title Test
24、code for machine tools: Part 1: Geometric accuracy of machines operating under no-load or finishing conditions Part 2: Determination of accuracy and repeatability of positioning numerically controlled axes Part 3: Determination of thermal effects Part 4: Circular tests for numerically controlled mac
25、hine tools Part 5: Determination of the noise emission Part 6: Diagonal displacement test Annexes A and B form a normative part of ISO 230. Annexes C, D and E are for information only. ISO 230-5:2000 (E) 3 1 Scope 1.1 General This part of ISO 230 specifies methods for testing the noise of stationary
26、 floor-mounted machine tools and related auxiliary equipment directly on the shop floor. The purpose of the measurements is to obtain noise-emission data for machine tools. The data obtained may be used for the purpose of declaration and verification of airborne noise emission from machine tools as
27、specified in ISO 4871, and also for the comparison of the performance of different units of a given family of machine tools or equipment, under defined environmental conditions and standardized mounting and operating conditions. For the purposes of this part of ISO 230, “auxiliary equipment” means h
28、ydraulic power packs, chip conveyors, coolant-oil mist extractors, heat exchangers, refrigerators, etc. Noise emitted by centrally operated auxiliary equipment, connected to several machine tools, shall be considered as background noise. General instructions are given for the installation and operat
29、ion of the machine under test and for the choice of microphone positions for the work station and for other specified positions. More detailed instructions can be found in specific noise-test standards for individual types of machine tools. Clause 11 specifies a method for measuring the emission sou
30、nd pressure levels at work stations and at other specified positions in the vicinity of a machine tool. This method follows the methods specified in ISO 11202 and ISO 11204. Clause 12 specifies a method for measuring the sound pressure levels on a measurement surface enveloping the machine tool and
31、for calculating the sound power level produced by the machine tool. This method follows the methods specified in ISO 3744 and ISO 3746. The determination of the sound power level on the basis of the intensity method (ISO 9614 and ISO 9614-2) is not dealt with in this part of ISO 230. 1.2 Types of no
32、ise and noise sources The methods specified in this part of ISO 230 are suitable for all types of noise emitted by machine tools. This part of ISO 230 is applicable to machine tools of any type and size, including devices, components and sub-assemblies. NOTE Measurements according to this part of IS
33、O 230 may be impracticable for very tall or very long machine tools, such as transfer lines. 1.3 Test environment The test environment that is applicable for measurements made in accordance with this part of ISO 230 is generally located indoors, with one or more reflecting planes present, meeting sp
34、ecified requirements, as described in clauses 11 and 12, respectively in 11.4.2 and in clause 12.3.2. ISO 230-5:2000 (E) 4 1.4 Accuracy grades Individual values of emission sound pressure levels at a fixed position and of the sound power level of a machine tool determined in accordance with the proc
35、edures given in this part of ISO 230 are likely to differ from the true values by an amount within the range of the respective measurement uncertainties. The uncertainties in measurements of emission sound pressure levels and in determinations of the sound power level arise from several factors whic
36、h affect the results, some associated with environmental conditions at the test site and others with experimental techniques. This part of ISO 230 deals with methods to determine the emission sound pressure levels and the emission sound power level, where the results meet grade 2 accuracy (engineeri
37、ng method) and grade 3 accuracy (survey method). Because of its higher accuracy, grade 2 should be achieved whenever possible. Specific information on measurement uncertainties is given in clause 7. Although grade 2 accuracy (engineering) is preferred, grade 3 accuracy (survey) is acceptable for noi
38、se declaration and most other purposes. In this part of ISO 230, only the determination of grade 3 is described completely. For grade 2, ISO 3744 and ISO 11204 shall also be used. 2 Normative references The following normative documents contain provisions which, through reference in this text, const
