British Standards
BSI Group pioneered the PAS format. Under the BSI model, any organization, association or group who wish to document standardized best practice on a specific subject, can commission a PAS, subject to the BSI acceptance process.A British Standard and a PAS must reach full consensus between all stakeholders on technical content. The timescale for the development of a PAS can be shorter, typically around 8 months, and is why it is sometimes referred to as a 'fast-track standard'.
