A PAS is a Publicly Available Specification-a type of document issued by BSI to serve a number of purposes; here to get an advance version of a 'standard' into the marketplace for use and development ahead of its permissible publication as a BS. In this case the document contains non-normative information so has to be in circulation as a PAS for around 18 months prior to being reissued as a BS. There are a number of documents under the "1192" nomenclature and it is likely that that once all of these are available for full BS publication they may be slightly reordered into a homogeneous set.
