This website is owned and sponsored by The Woodhouse Partnership Ltd and provides a high-level introduction to the PAS 55 Standard (the specification for the optimized management of physical assets). Its development was led by the Institute of Asset Management.

What is PAS 55?

PAS 55 is the British Standards Institution's (BSI) Publicly Available Specification for the optimized management of physical assets - it provides clear definitions and a 28-point requirements specification for establishing and verifying a joined-up, optimized and whole-life management system for all types of physical assets. Now internationally recognized, PAS 55 is proving to be an essential, objective definition of what is required to demonstrate competence, establish improvement priorities and make better, clearer connections between strategic organizational plans and the actual day-to-day work and asset realities.


PAS 55 has proven very successful, with widespread adoption in utilities, transport, mining, process and manufacturing industries worldwide. The 2008 update (PAS 55:2008) was developed by 50 organisations from 15 industry sectors in 10 countries. The International Standards Organisation (ISO) has now accepted PAS 55 as the basis for development of the new ISO 55000 series of international standards. More information?
