It explains the revision of the1967 edition of BS4140, and supersedes BS4140-0:1980, which is
6、withdrawn. For many years the UK has participated in the work of Subcommittee7, Aluminium and related compounds, of Technical Committee47, Chemistry, of the International Organization for Standardization (ISO). The test methods, applicable to aluminium oxide primarily used for the production of alum
7、inium, that were approved by the UK were published in BS4140:1967 and in three subsequent addenda. The original ISO recommendations for methods of test have since been largely confirmed as full International Standards and, in accordance with BSI policy, these have been published as separate dual-num
8、bered Parts of BS4140. Table 1 details these Parts and indicates, where applicable, their relationships with the clauses of BS4140:1967 and its three addenda, which have been withdrawn. It should be noted that the ISO method for determination of calcium content has been considered to be unsuitable f
9、or use in the UK, and it is intended to produce an appropriate British Standard method (Part14). Part15 “Determination of zinc content (PAN photometric method)” will not be issued, as the UK approved a proposal for the withdrawal of the International Standard. A British Standard does not purport to
10、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. Summary of pages This document comprises a front cover, an inside front cover, p
