What are standards?

Standards are documents that establish a common technical specification, so products and processes can work safely, reliably and consistently. Some standards provide a common terminology or set of symbols for a particular field, to make sure different organisations are talking about the same thing when they use a given term or symbol. Standards are very commonly used in all branches of engineering.

Standards are published by a variety of different organisations, which often have a focus on a specific country or area of engineering.

Standards do not have the force of law in themselves: however, laws and regulations will often require you to meet certain standards, and so you may well have to follow those standards if you wish to manufacture or sell a product or service in a given country.

Main sources for standards

We have major collections of broad-ranging standards from three organisations. You can access all current standards from each organisation as PDFs, as well as some withdrawn and draft material.

ISO & CEN standards

We do not subscribe to ISO or European CEN standards. However, BSI frequently adopt these standards as their own, with the result that the equivalent British Standard  will be exactly the same as the ISO or CEN standard: in those cases, standards will have a standard number which begins BS ISO, BS EN or BS ISO EN . As a result, it is often worth searching for the standard number of an ISO or CEN standard on British Standards Online.

Some European standard organisations, such as the French AFNOR or German DIN standards, also adopt the same CEN standards as BSI: it is also worth searching for their standard numbers on British Standards Online.

What are patents?

A patent is a licence from a government which gives an inventor exclusive rights to create, sell or use an invention they have developed. As patents must describe how the invention functions, they are excellent sources of technical data on how products and processes work.

From Monday 20th July, you can now request items via Library Search to collect from Adsetts Library. You will be able to request items to collect at Collegiate Library from Monday 27th July. You can also return Library items to either site. Please see the Click & Collect and Returning items page for full details.

If you cannot find and access the item you need using Library Search or your subject guide, please make a request using the forms on this page and we will do our best to provide you with online access or suggest alternative resources within one working day.

For books and other media use the RoR request form: bit.ly/libraryror

For journal articles use the Document Supply Services request form

We can provide access to electronic books, book chapters, journal articles or media such as film and TV recordings.

Please note you will need to complete the form for each item you require.

Resources On Request (ROR) is an emergency service that we have developed in response to the COVID-19 pandemic. Thank you for your patience and understanding as we adapt our services to support your learning, teaching and research off-campus.

If you would like something added to the library collection for Autumn 2020 please Suggest a Purchase.
