It is identical with ISO 1483:1983, published by the International Organization for Standardization (ISO). EN ISO 1483:1994 was produced as a result of international discussions in which the United Kingdom took an active part. The References clause of EN ISO 1483 states that the International Standards ISO 3269 and ISO 4042 are at the stage of draft. These were subsequently published as follows: 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.
