The UK's pre-ISO 19650 suite of BIM information-management standards. The PAS 1192 series (published by BSI, the British Standards Institution) was the UK's national suite of specifications for managing BIM information before ISO 19650 existed. PAS 1192-2 covered the capital delivery phase, PAS 1192-3 covered operational asset management, and PAS 1192-5 covered security-minded BIM.

ISO 19650 was built directly on top of PAS 1192 - the CDE zones (WIP, Shared, Published, Archive), the EIR/BEP pairing, and much of the terminology carried over almost unchanged. If you read an older UK BIM specification or contract, it likely still references PAS 1192 by name.
