IHB File N° S3/8151/ENCWG CIRCULAR LETTER 18/2015 26 February 2015 CANCELLATION OF THE VOTE ON THE IMPLEMENTATION DATE FOR EDITION 5.0.0 OF THE IHO STANDARD S-58 – ENC VALIDATION CHECKS References: A. IHO CL 08/2015 dated 16 January – Implementation date for edition 5.0.0 of the IHO Standard S-58 - ENC Validation checks; B. IHO Resolution 2/2007 as amended - Principles and procedures for making changes to IHO technical standards and specifications. Dear Hydrographer, 1. Reference A sought the approval of Member States to set 1 January 2016 as the implementation date for Edition 5.0.0 of the IHO Standard S-58 - ENC Validation Checks. After that implementation date, Edition 4.2.0 would be retired and only S-58 Edition 5.0.0 would be fully in force and would require that ENC data must not contain any critical error. 2. The Directing Committee has just been informed by the Chair of the ENC Standard Maintenance Working Group that a number of inconsistencies, grammatical omissions and some logic errors had been identified and that a revised version will be necessary to address these issues. The revision is being prepared by the Working Group. 3. As a consequence, the vote by the CL in Reference A is cancelled. 4. A draft revised version of Edition 5.0.0 of S-58 will be submitted for the approval of the Member States together with the appropriate proposed implementation date, after its endorsement by the Hydrographic Services and Standards Committee (HSSC), in accordance with Reference B. On behalf of the Directing Committee Yours sincerely, Gilles BESSERO Director Distribution: - IHO Member States - IC-ENC - Primar - Chair, HSSC - Chair, ENCWG
