Foreword
This Section of Part 6 of BS 6100 has been prepared under the direction of the Basic Data and Performance Criteria for Civil Engineering and Building Structures Standards Committee This Section supersedes BS 4340 “Glossary of formwork terms”, which is therefore withdrawn
A general introduction to and explanation of this glossary is given in Part 0 of
BS 6100 which itemizes the Parts, Sections and Subsections into which this glossary is divided and provides a general alphabetical index of all the terms in the Sections and Subsections already published Those using individual Sections and Subsections of this glossary are urged to consult Part 0 when doing so The other Sections of this Part are as follows:
Terms are listed alphabetically in the index and are referred to by numbers which are found against the term in the body of the Section They are arranged in a classified order, each term having an individual number consisting of seven digits
in two parts, the first of three digits, the second of four The first three digits represent the number of the Part, Section and Subsection (in this case, the third digit is 0 as there is no division into Subsections) The fourth digit represents the group of terms, the fifth digit represents the subgroup of terms (in this case, the fifth digit is 0 as there is no division into subgroups) and the last two digits represent the place within the subgroup
Deprecated terms are given in medium type below the preferred term with their status indicated 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 “inflatable formwork” are written in a direct style, not as “formwork, inflatable” The inverted term is included in the index with a reference to the direct term
Italicized words indicate terms that are defined elsewhere in this Section
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.
