A. CL 47/2018 dated 03 October 2018 – Adoption of Edition 6.1.0 Of IHO Publication S-
58 – ENC Validation Checks.

Standards Committee (HSSC).
Dear Hydrographer
1. Edition 6.1.0 of Publication S-58 – ENC Validation Checks – was published in 2018
(Reference A).
2. Edition 6.1.0 of S-58 introduced a new category of check ‘Critical Error’ in order to
specify a minimum standard to which all ENC datasets must comply with S-57, Appendix B.1
– ENC Product Specification. In order to better support safe navigation no ENC data set should
be issued by an ENC service provider for use in ECDIS if any of these errors are detected.
3. In support of the introduction of critical error checks the IHO has created a set of ENC
test data that can be used to verify that ENC production systems will correctly identify all critical
errors in S-58 Edition 6.1.0. These datasets are available for download from the IHO website
at: https://www.iho.int/iho_pubs/standard/S-58/datasets/S-58_datasets.htm
4. Hydrographic Offices are also reminded that S-58 edition 6.1.0 will enter into force on
01 September 2019, at which time Edition 5.0.0 will be retired. Accordingly, from 01
September 2019:
- all new ENCs must comply with Edition 6.1.0;
- all ENC updates and new editions must include any corrections required to ensure
that the updated ENC comply with Edition 6.1.0.
5. Both Regional ENC Coordination Centres (RENCs) have confirmed their intention to
follow the conformance rules contained in S-58 edition 6.1.0 and will advise their members
and service providers that any new ENC cell, new edition or update containing a critical error
will not be suitable for use in an ECDIS. Hydrographic Offices should note that this requirement
is not retrospective, and will not impact on ENC datasets previously published.
On behalf of the Secretary-General
Yours sincerely,
Abri KAMPFER
Director
