We have reviewed the need for the tests required by the standard. Some rationalisation has been achieved in the revised draft. Check for “should” and change to “shall” where appropriate. UK 0 ge The testing requirements are likely to be significantly more onerous than the previous version of the standard. 1. Is there scope to reduce the number of tests needed? 2. Will manufacturers want to use this standard when published? UK 0 ed There are a number of occurrences of the “should” were it ought to be “shall” Accepted - All occurrences of “should” have been review, and in most cases they have been changed to “shall” UK 03 ed Should there be a list of symbols used (e.g. t, ς, a(ς) …) Introduce list of symbols at start of clause 3. Accepted Accepted – The symbols have been reviewed and rationalised. Can another symbol be used, or alternative approach be adopted to solve the problem of the need for multiple versions of “time” in these equations? ed Use of ς in equations is queried. This symbol is associated with the damping factor in the context of vibration control. UK 03 Equations 1,3,4 Accepted ed The format of these equations should be consistent with that of 1,3, and 4 (i.e. use ς as integrand – but see note above) ed Title for Figure 1a is unclear due to page break between 1a and 1b. UK 03 Equations 5 and 6 Accepted Options: • Make Figs 1a and 1b appear on one page. • Re-state title in Fig 1a UK 03 Figure 1a Figure 1b • Renumber as Figures 1 and 2 UK 03 Figure 1b ed Spelling Change “Band-limitting” to “Band-limiting” Accepted Accepted UK 03.4.7 ed Emphasise that this is bot positive and negative peaks Change definition to : “modulus of the maximum instantaneous positive and negative peak value of the frequency weighted acceleration” ed Grammar Change to “Time-averaged” and “Band limited”.
