It is identical with ISO2341:1986, published by the International Organization for
9、Standardization (ISO). EN22341:1992 was produced as a result of international discussion in which the United Kingdom took an active part. This British Standard supersedes BS5894:1980 which was identical to ISO2341:1972 and has now been withdrawn in accordance with the CEN/CENELEC Internal Regulation
