Because imperial film dimensions are still widely used in the UK, it was considered necessary to list the equivalent imperial film dimensions alongside the metric film sizes. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations.
