12、n for Standardization (ISO) with the active participation and approval of the UK. In1988 the European Committee for Standardization (CEN) accepted ISO7574-1:1985 as European Standard EN27574-1:1988. BS6805 at present comprises the following Parts. Part1: Glossary of terms; Part2: Method for determin

13、ing and verifying stated values for individual machines; Part3: Method for determining and verifying stated values for batches of machines using a simple (transition) method; Part4: Methods for determining and verifying stated values for batches of machines. Further Parts of BS6805 will be prepared,

14、 if required. Terminology and conventions. The text of the International Standard has been approved as suitable for publication as a British Standard without deviation. Some terminology and certain conventions are not identical with those used in British Standards; attention is drawn especially to t

15、he following. The comma has been used throughout as a decimal marker. In British Standards it is current practice to use a full point on the baseline as the decimal marker. Wherever the words “ISO7574” or “part of ISO7574” appear, referring to this standard, they should be read as “BS6805” or “Part

16、of BS6805” respectively.

35、n to ISO7574 In order to state the noise emission value for a machine or a batch of machines in an unambiguous manner, this four-part series of International Standards provides guidelines for determining the noise emission value to be stated (e.g.as a labelled value) and specifies verification proce

36、dures. These methods are based on the premise of clearly defined acoustical measurement methods and describe the handling of the variability of the measurement results and, if relevant, of the noise emissions of the machines in a batch. The methods presented in this series of International Standards

37、 are compatible with the requirements specified in ISO4871, i.e., the stated (e.g.labelled) value indicates the limit below which the noise emission value of the individual machine and/or a specified large proportion of the noise emission values of the batch lies; the basic noise emission quantity u

38、sed is the A-weighted sound power level. Although this series of International Standards is drafted mainly in terms of A-weighted sound power level as a noise emission quantity, it is equally applicable to other quantities. In this series of International Standard the term “label” is considered to i

39、nclude all means for providing information on the noise emission values to potential users of the equipment; this includes labels, brochures, advertisements, commercial literature, etc. Requirements for this may be stipulated, for example in a contract or in regulations. The methods described may be

40、 applied not only to values stated for labelling purposes, but also to values stated for other purposes, for example: to the upper noise limit set by an authority or specified in a technical standard for a specific family of machines; to contract values as agreed by the manufacturer and purchaser of

41、 the machine(s). This series of International Standards does not specify whether, or for which specific family of machines, the purposes mentioned above are relevant or whether the methods for determining and verifying stated noise emission values should be applied. This is left to a labelling code

42、specific to the machinery or equipment concerned or, if this does not exist, to an agreement between the users of the standards (e.g.in a contract). Two cases are considered: the stated value is given for one individual machine; the stated value is given for an entire batch of machines. For economic

43、 reasons, the stated values for batches of series-produced machines may be verified by sampling procedures. This four-part series of International Standards does not deal with the consequences that ensue if the stated value is not verified for a single machine or for a batch (lot) of machines. This

44、series of International Standards which comprise ISO7574 requires that the labelled value be determined using the same measurement test code as that specified for verification. It therefore applies to families of machines or equipment for which special measurement test codes for the determination of

45、 noise emission quantities are prepared. If no special test code for a particular family exists, the methods specified in ISO3741, ISO3742, ISO3743, ISO3744 and ISO3745 may be appropriate. NOTEThis does not preclude the use of other International Standards, e.g.ISO3746, which may form the basis of s

46、pecial measurement test codes. In each case the installation and operating conditions typical for normal use shall be clearly specified or agreed. The relevant measurement conditions may provide information, in the form of standard deviations, on the dispersion of measurement results. A measure for

47、the dispersion of the emission values due to the different emissions of the different machines is the standard deviation of production (see3.18). The series of International Standards which make up ISO7574 comprises the following four parts: Part1: General considerations and definitions; Part2: Meth

48、ods for stated values for individual machines; Part3: Simple (transition) method for stated values for batches of machines; Part4: Methods for stated values for batches of machines. 1 Scope and field of application This part of ISO7574 defines terms relating to methods for determining and verifying

49、the stated (e.g.labelled) values of the noise emitted by machinery and equipment. This four-part series of International Standards applies both to machines which are produced in very small quantities as well as to machines which are produced by mass production methods.EN27574-1:1988 4 BSI 11-1999 2 References ISO3534, Statistics Vocabulary and symbols.
