With a view to avoiding any possibility of unintentional/random changes to the content or format of the electronic versions of RS Publications (rules, guidelines, instructions, etc.), that might be introduced due to the use of a software intended exclusively for editing/formatting and publication of paper versions (books), RS is currently converting all RS Publications into a new platform and format of documents/files.
Due to the aforementioned conversion, the publication of updated versions might be delayed for some Rules/Guidelines due to unavailability of the converted versions that had to be further modified as per Circular Letters or agreed editorial amendments. RS does the best to make such a delay as short as possible. Until the dates of updated versions' publication the latest versions of RS Publications have to be used/applied/referred to together with the applicable Circular Letters providing information on recently approved, but not yet introduced, amendments to RS Publications and the entry-into-force dates of the amendments.
