We think this comment arises
due to the draft CD2
confusing cross-talk and
cross axis sensitivity, which
produces this comment. We
think the confusions have
been dealt with in the revised
draft.
JP 05.17 te ISO 16063 does not give any description on multi-axes
calibration technique. IEC 60747-14-4 only gives the
description on the derivation of cross sensitivity.
JP 11.10.2 te Linearity of phase is requested to be written. Rejected –There are now
signal burst tests that would
be adversely affected by
poor phase response
linearity.
See previous responses to
Japanese comments on 5.04
and 5.17. We do not believe
that the level of information
suggested here is necessary.
Clear description is necessary that the reference
accelerometer for human vibration can provide the
data for sensitivity as a matrix with every
component as a function of frequency.
JP 11.11.3 te ISO 16063-21 does not give the technique of cross
sensitivity. It does not say anything about the frequency
dependency of cross sensitivity.
JP 12.09 te Linearity shall be stated in terms of phase. The new signal burst tests
attempt to provide multifrequency
inputs that would
be adversely affected by
incorrect phase responses.
Rejected - We think this
comment arises due to the
draft CD2 confusing crosstalk
and cross axis
sensitivity, which produces
this comment. We think the
confusions have been dealt
with in the revised draft.
JP 12.10.3 te ISO 16063-21 does not give the technique of cross
sensitivity. It does not say anything about the frequency
dependency of cross sensitivity. Is there any calibration
laboratory that can provide cross sensitivity under the
concept of matrix sensitivity ?
