Publicly Available Specification

From Wikipedia, the free encyclopedia
Jump to: navigation, search

A Publicly Available Specification or PAS is a standardization document that closely resembles a formal standard in structure and format but which has a different development model.[1] The objective of a Publicly Available Specification is to speed up standardization. PASs are often produced in response to an urgent market need.[2]


BSI Group develops PASs in the UK,[1] while the International Electrotechnical Commission develops international PASs in the arena of electrical, electronic and related technologies,[2] and the International Organization for Standardization develops international ISO PASs.[3]

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.The main difference is in the area of consensus. A British Standard must reach full consensus between all stakeholders on technical content, whilst a PAS invites comments from any interested party but does not necessarily incorporate them. This means that 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'.[4]

The development of a PAS cannot conflict with, or contradict, existing or draft work within the formal standards arena and must complement, not conflict with, any legislation in the subject area. It is also written in accordance with BS drafting rules, which means that the content must be technically robust and cannot be technically constrained (i.e. it cannot include patented or proprietary methods or products). It is written unambiguously and with objectively verifiable requirements or recommendations.[1]

Origin of term "PAS"[edit]

According to a BSI document "Principles of PAS standardization" "The term PAS was originally an acronym derived from “publicly available specification”. However, not all PAS documents are structured as specifications and the term is now sufficiently well established not to require any further amplification." However, early examples of PAS were actually titled "Product Approval Specification" as illustrated in the accompanying photograph showing part of PAS 003.
