We endeavour to make sure that every page complies with the World Wide Web Consortium's Web Content Accessibility Guidelines (WCAG 2.0), as part of its Web Accessibility Initiative (WAI). This site has been built to achieve Priority Level 2 (AA) checkpoints.


To illustrate how compliancy has made this site accessible, we have listed representative disabilities below and explained how this site meets the users' needs.


Visual (impaired)

Those with visual impairments (e.g. myopia) can scale on all pages on the site to suit their own requirement. All text on pages is scaled, including all menu items.



There is some content on this site that cannot be accessed by the deaf or hard of hearing, namely embedded videos and audio clips. This content is mostly supplementary to the pages it appears on. Text versions of the audio files are not available.



This site may be fully accessed using any voice-controlled computer and web browser.



For those that have difficulty using a mouse, keyboard access is supported by using standard shortcut techniques. This site can be fully navigated without the use of a mouse.



The layout of this site is uniform on all pages. The main menu is structured identically on all pages.



There are no animated images or flashing text on this site which could – in extreme cases – cause difficulty for some suffering from particular neurological disorders.


Text scaling

All text on this site is specified in percentage terms, meaning that its size can be increased inside the browser window for easier viewing. The ability to support text scaling varies from browser to browser, but given below are some guidelines for the latest versions of the more popular browsers:


In Internet Explorer, select the View | Text Size menu command. You can then choose from a range of text sizes (Largest, Larger, Medium (default), Smaller and Smallest). Note that Internet Explorer cannot resize images

In Mozilla Firefox, select the View | Text Size menu command. You can then opt to increase or decrease your text size. Note that Mozilla Firefox cannot resize images

In Opera, select the View | Zoom menu command. You then have range of percentages to choose from. Opera scales everything on the page, not just text, so images will also increase in size as you increase the zoom factor

In Safari (Mac OS), select the View menu command. You can then opt to make text bigger or make text smaller. Note that Safari cannot resize images

Even the same browser product can behave differently on different platforms. For example, Internet Explorer on the Mac will scale images, whereas the Windows version cannot. Check with your supplier for details.
