The publicly available specification (PAS 124) will be developed using a two-stage process. A BSI steering group will review and provide feedback on the specification before it is made available for public comment.
The steering group will include representatives from Shell, Unilever, Institute of Directors, Interbrand, The Institution of Engineering and Technology (IET), and the Localisation Industry Standards Association (LISA).
"The specification will enable organisations and their suppliers to better understand the need for web standards and consequently provide structured websites," said Mike Low, director of BSI British Standards.
The development of the publicly available specification (PAS 124) was commissioned by UK web content company Magus.
The firm said research showed many organisations did not have formal standards defined to govern their websites. It said the specification would provide a framework to help apply standards to improve online performance and protect the integrity of their brands.
