Standardising the compressed air industry

25 September, 2015

On the 19th March 2015, the European Committee for Standardisation (CEN) made EN ISO 11011, the International Standard for compressed air efficiency, an approved European Standard.

Prior to EN ISO 11011, individual manufacturers and suppliers had to decide for themselves how to measure compressor energy consumption, and what recommendations to make to their customers. With the introduction of EN ISO 11011, companies can now offer advice and carry out assessment and auditing procedures on a level playing field. Like for like energy audits can only benefit the end-user and make it easier for them to decide what action to take.

BCAS would strongly encourage end-users to see the value in assessing their compressed air usage within a standardised framework. It is likely that many businesses don’t know how much compressed air they use, or how much it costs them. EN ISO 11011 should deliver sustainable results for the businesses that take it on board, saving energy and reducing carbon emissions.

Both the Written Scheme of Examination and EN ISO 11011 are in place to protect end-users of compressed air. Legislation offers a standardised service that can be trusted and used across the industry. However, there is much more to be done.
