Section One: Vibration tests (sinusoidal)
FOREWORD
1) The formal decisions or agreements of the IEC on technical matters, prepared by Technical
Committees on which all the National Committees having a special interest therein are
represented, express, as nearly as possible, an international consensus of opinion on the
subjects dealt with.
2) They have the form of recommendations for international use and they are accepted by the
National Committees in that sense.
3)
In order to promote international unification, the IEC expresses the wish that all
National Committees should adopt the text of the IEC recommendation for their national
rules in so far as national conditions will permit. Any divergence between the IEC
recommendation and the corresponding national rules should, as far as possible, be clearly
indicated in the latter.
PREFACE
