Together with Parts1 and3 it forms a revision of BS3446:1962, which is withdrawn. Much of the work in preparing BS34
9、46 was conducted under a joint BSI/DTI 1)consultancy scheme. BS3446 is published in three Parts: Part1: General and manufacturing (sections1 to6); Part2: Applications in the coke, glass, cement and other non-metallurgical industries (sections7 and8); Part3: Applications in the metallurgical industri
10、es (section9). Terms are listed alphabetically within each section. Each term has an individual number consisting of five digits in two parts, the first of two digits, the second of three. The first two digits represent the number of the section and subsection. The last three digits represent the pl
11、ace that the term occupies within the section or subsection. Alternative terms are given below the preferred term. These terms are not individually numbered, but are included in the index with a reference to the preferred term. Terms of more than one word, e.g.“drawing chamber”, are written in a dir
12、ect style, not as “chamber, drawing”. Italicized words indicate terms that are defined elsewhere in this Part of BS3446. The definitions presented in this Part of BS3446 give the general meaning of terms, and should not be interpreted as being legally binding. A British Standard does not purport to
13、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
