The Institute of Physics pages aim to achieve the AA-Standard set out by the W3C (www.w3.org). This is roughly equivalent to the 'See it Right' Standard set by the Royal National Institute of the Blind (www.rnib.org). The AA-Standard is a little more strict in some areas - less in others.
In some parts of the site you may see the above logo which indicates that the pages in that section fully comply with this standard.
