ETSI EG 201 058

The present document is intended to be used by specifiers of Implementation Conformance Statement (ICS) proforma. It provides recommendations and practical guidance in order to produce ICS proforma and profile requirement lists. It contains also a template of an ICS proforma specification for a base standard and an example of requirement list for a profile. The present document does not cover Managed Object Conformance Statement (MOCS) proforma.

Within ETSI, ICS proforma are generally produced using Microsoft® Word for Windows™. The present document gives specific guidance on its use, in this particular context. The electronic version of the template of a base specification ICS proforma, and the example of a requirement list are available. The electronic version of the template should be used as the physical basis of an actual ICS proforma, with minimum modifications.

The present document should be applied in ETSI for the development of new ICS proforma. Existing ICS proforma do not have to be modified in order to comply with the present document.

Moreover, when work is being performed in collaboration with other standardization instances (e.g. at an international level, either in the form of an ETSI profiling activity on a base ICS proforma specification provided by ITU-T or ISO, or in the form of a planned contribution) the present document should be used to the extent necessary to allow compatibility with any practice in use in the concerned group.
