Date: 2003-07 ISO/TC 108/SC 3 N 388-CEN/TC 231 N 439 Report of voting on doc. 108/3 N 367-CEN/TC 231 N 402 Second ISO/CD 8041 "Human response to vibration - Measuring instrumentation" 1 2 (3) 4 5 (6) (7) Comment (justification for change) by the MB Proposed change by the MB Secretariat observations on each comment submitted Type of comment2 Paragraph/ Figure/Table/ Note (e.g. Table 1) Clause No./ Subclause No./ Annex (e.g. 3.1) MB 1 Maximum transverse... and delete 4 times < Accepted DE E.2 Table E.1 ed include in last 2 rows Minimum to read: Minimum resonant frequency Suggested minimum enclosure specifications...

Comment accepted – but sentence changed DE F.1.2.1 5th para ed add r.m.s. to read: ...with an overall Wh r.m.s. value of 10 m/s². Accepted Comment accepted – test changed. Should have said “no greater than” DE F.1.2.1 6th para te just a lower limit for the increment is too less, the user needs a precise range in order not to use too wide steps DE G.3 ed read heading: Vibration sensitivity Accepted DE G.4 f) ed read as in G.7 e) ...lengths and a description of the nature... Accepted – also delete “the nature” DE G.8 e) ed add as to read: ...frequency-weightings as time-average... Accepted DE G.9 h) ed repetition from G.4 g) Accepted Rejected – a) Not customary to have such an annex. Use as a basis the attachment to these comments and the outline by Mr. Bress, already handed out to the working group b) It is ISO 2631 that changed the weightings in 1997, not ISO 8041 DE H ed Additionally to the short statements in the Foreword, we propose a new informative annex H giving a comparision between the old 8041 and this new edition. It should include a description of the effect of the new Wk on measured values, and of the new linear time-weighted running r.m.s. compared to the exponential time weighting. c) For instrumentation, the change in weightings was introduced in the 1999 amendment to ISO 8041, not in this revision.

DE Z Biblio ed move ISO 16063-21 to clause 2 Rejected – ISO 16063 (all parts) is in clause 2, Reference in bibliography therefore deleted DE Z Biblio ed delete IEC 60651 since this is outdated, see IEC 61672-1 Accepted DE Z Biblio ed delete EN 50082-2 since it is replaced by IEC 61000-6-2 Accepted DE Z Biblio ed delete EN 55022 since it is identical with CISPR 22:1997 Accepted Accepted DE Z Biblio ed move the GUM to clause 2 since it is quoted in 11.1 and 12.1 with "shall" DE Z Biblio ed check quotation number [8] in C.2.3! Accepted – should now be [6] Comment appreciated. FR 0 ge France appreciates the work done, otherwise it appears that CD2 is not covering the field of ISO 5349-2. Rejected – Human vibration measurement standards require measurement in single axes. For hand arm vibration the three axes are combined to produce an overall level. If these transducers are applicable to human vibration measurement, then the new standard could be included in the bibliography – but only when it appears as a full standard. Add IEC 60747-14-4, 47E/220/CD to the list of references. JP 02 te IEC has issued the first committee draft for semiconductor accelerometer standard 60747-14-4 47E/220/CD, where acceleration is treated as vector quantity. Calibration is described using vector acceleration. 1 MB = Member body (enter the ISO 3166 two-letter country code, e.g. CN for China; comments from the ISO/CS editing unit are identified by **) 2 Type of comment: ge = general te = technical ed = editorial NOTE Columns 1, 2, 4, 5 are compulsory. page 11 of 25 ISO electronic balloting commenting template/version 2001-10
