FOREWORD
1) The formal decisions or agreements of the I E C 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 I E C expresses the wish that all National Committees should adopt the text
of the I
E C recommendation for their national rules in so far as national conditions will permit. Any divergence between the
I E C recommendation and the corresponding national rules should, as far as possible, be clearly indicated in the latter.
4) The I E C has not laid down any procedure concerning marking as an indication of approval and has no responsibility when an
item of equipment is declared to comply with one of its recommendations.
