Introduction
This Technical Report contains replies to requests for interpretations with regard to the understanding of
clauses in EN 14764:2005. The replies concern those requests which have resulted in an interpretation, or a
decision that no action is required as the standard is sufficiently clear.
An interpretation does not have the same status as the text of the standard, nor can it overrule the text of the
standard. However, following an interpretation should give assurance that the relevant clause of the standard
has been correctly applied. An interpretation shall only be regarded as a clarification of the meaning of the
standard.
Requests for interpretation
Requests for interpretations may be submitted by a CEN member body through its national committee or by a
CEN/TC 333 liaison (but not directly by an individual or a company) − in accordance with the interpretation
protocols agreed by CEN/TC 333 and resumed in Doc. CEN/TC 333 N 182. The requests are then channelled
to the relevant TC 333 working party which will deal with the request.
A request for an interpretation may lead to:
a) An interpretation of the standard
This should reflect a reasonable interpretation of how the standard should be used, taking into account:
1) the wording of the standard;
2) the rationale of the standard;
3) the history of the standard.
b) A no action decision
This is applicable when it is agreed that the standard appropriately specifies how a cycle or a component shall
be assessed.
c) A proposal for an amendment of the standard
This is applicable when it is agreed that the standard is deficient in some way.
NOTE The interpretations and no-action decisions are published in this Technical Report, which will be updated on a
regular basis.
Proposals for amendments will be progressed as new work item proposals in accordance with CEN rules.
Answers to requests for interpretations
Since requests for interpretations are submitted through a CEN member body, it is assumed that the member
body will keep itself informed about decisions concerning the request and its progress and will itself inform the
originator of the request as appropriate.
Disclaimer
The interpretations have been derived by the Interpretation Panel Group. The information contained
herein is for guidance only and does not reflect the formal approval by CEN or CEN member bodies. It
