29、99 v National foreword This British Standard has been prepared by Technical Committee MTE/1. It is identical with ISO7960:1995, Airborne noise emitted by machine tools Operating conditions for woodworking machines prepared by the International Organization for Standardization (ISO).

30、rd does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Cross-reference International Standard Corresponding Brit

This will be indicated in the amendment table on the inside front cover.vi blankBS7140:1995 BSI 11-1999 1 1 Scope This International Standard, together with basic noise emission International Standards, describe

33、s the mechanical and acoustical specifications necessary for a reproducible test method for the determination of airborne noise emitted by woodworking machines. NOTE 1Acoustic measurement procedures and noise data reporting are given in the basic acoustic standards selected from the ISO3740 series,

34、ISO4871 and the ISO11200 series (seeAnnex V). This International Standard specifies operating conditions and microphone positions for the measurement of noise emitted by woodworking machines. It applies to: single-blade circular saw benches (Annex A); planing machines (Annex B); thickness planing ma

35、chines (Annex C); single-spindle moulding machines (Annex D); double-end profiling machines (Annex E); edge banding machines (Annex F); double-end sizing and edge banding machines (Annex G); two-side and multi-side planing machines and moulding machines (Annex H); bandsawing machines (Annex J); sing

36、le-end tenoning machines (Annex K); routing machines (Annex L); double-end trim circular machines (nonstroke) (Annex M); single-blade stroke circular sawing machines for cross cutting (Annex N); vertical and horizontal panel sizing sawing machines (Annex P); multiblade circular sawing machines (for

37、ripping) (Annex Q); sanding machines (Annex R); double-edging circular sawing machines (for rough cutting) (Annex S); double-blade stroke circular sawing machines for cross cutting (Annex T); double-end tenoning machines (for tenoning only (Annex U). The existence of special-purpose machines, for wh

38、ich such standard operating conditions cannot be specified, is acknowledged. This International Standard applies to the types of woodworking machines listed above. Additional types will be covered in future editions of this International Standard (ISO7960). 2 Normative reference The following standa

39、rd contains provisions which, through reference in this text, constitute provisions of this International Standard. At the time of publication, the edition indicated was valid. All standards are subject to revision, and parties to agreements based on this International Standard are encouraged to inv

41、ng. 3 Definitions For the purposes of this International Standard, the definitions given in ISO7984 apply. 4 General provisions for machine installation and operation Specified operating conditions for particular types of machines are given in the annexes. When testing multi-purpose machines, each f

42、unction shall be mounted separately according to the requirements specified in the annexes. 4.1 Machine installation The machine shall be installed according to the manufacturers instructions. If the manufacturer does not provide such instructions, this shall be stated in the test report, together w

43、ith the installation method used. The machine shall be installed in such a way that access to all sides is possible. 4.2 Machine operation The operation during measurement shall be representative of the noisiest normal and typical use of the machinery that is reproducible. Standard operating conditi

44、ons shall be those specified in the relevant annex. Where conditions are not specified in annexes, manufacturers instructions shall be followed. Where neither specifications nor instructions exist, the machine shall be set up to give maximum noise emission. The machine shall be tested when carrying

45、out a sequence of operations deemed to be representative of the use of the machine, using test materials and operating conditions specified in the relevant annex. In addition, a test shall be performed under no load. The level of the no-load noise is that produced when the machine is running, ready

46、for load test, unless otherwise specified in the annex.BS7140:1995 2 BSI 11-1999 NOTE 2Distinctive features of noise within the machine-cycle may have to be measured separately or may be included in a single measurement of equivalent continuous sound pressure level sampled over the whole operating c

47、ycle. Machines with provision for dust extraction shall be tested with the extraction working, under both idling and operating conditions. In order to determine the influence of the dust extraction system on the total noise, an additional measurement shall be carried out at a point at the operator p

48、osition (see suggested figures in the annexes), with the dust extraction switched off. The operating conditions and the sequence of operations shall be defined, recorded and reported. New or re-sharpened tools shall be used for all tests under load and the machine shall be running at normal operatin

49、g temperature. General safety requirements shall take precedence over conditions specified in the annexes. 4.3 Specification of test materials The test material shall be one of the materials specified in4.3.1 to4.3.3. 4.3.1 Particle board, made from particles of wood bonded with synthetic resin and/or organic binder, density500kg/m 3to750kg/m 3 , three-layer construction and moisture content6% to10%. 4.3.2 Coated particle board, of the type specified
