B.S. 648 : 1964

THIS BRITISH STANDARD, having been approved by the Building Divisional Council, was published under the authority of the General Council on 31st December, 1964.

The Institution desires to call attention to the fact that this British Standard does not purport to include all the necessary provisions of a contract.

In order to keep abreast of progress in the industries con- cerned, British Standards are subject to periodical review. Suggestions for improvements will be recorded and in due course brought to the notice of the committees charged with the revision of the standards to which they refer.

A complete list of British Standards, numbering over 9,000, fully indexed and with a note of the contents of each, will be found in the BSI Catalogue which may be purchased from BSI Sales Department. The Catalogue may be consulted in many public libraries and similar institutions.

British Standards are revised, when necessary, by the issue either of amendment slips or of revised editions. It is important that users of British Standards should ascertain that they are in possession of the latest amendments or editions.

The following R.S.I. relcrcnccs relate IO the work on this standard: Committee rcference B/19 Draft for comment D63/9318

BRITISH STANDARD SCHEDULE OF

WEIGHTS OF BUILDING MATERIALS

FOREWORD

The title of this standard should not be taken to imply that all of the materials quoted are necessarily used solely or even principally in building.

This schedule was first published in 1935 as an attempt to provide a solution to the problems which had arisen through structural and other calculations being based on different data for the weights of materials con- cerned. The 1949 revision was undertaken with a view to making the information more complete by the inclusion of certain extra materials, together with such changes in the data as had been found to be necessary.

The present revision continues this process of improvement and development. It contains additional new materials which have since come into use for building purposes and amends the weights of many other materials in the light of up-to-date information. Some materials have been introduced into the standard which will not be present as such in a completed building but a knowledge of whose weights is important for calculations both prior to and during the course of execution of the works. Weights of blockwork, brickwork and stonework have, however, been given in preference to weights of blocks, bricks and stone, as likely to be more helpful to users in view of the main purpose of this standard. At the same time the opportunity has been taken of including in the schedule much of the supplementary information previously given in an appendix.

It has not been found possible to include weights for the many different forms of composite construction coming into use, many of which are still in process of development and capable of many variations and combinations; weights of as many individual component materials as were feasible have, however, been given, from which it is hoped that users will be able to derive any composite weights required. The committee was aware, nevertheless, of certain integrally composite materials, which are difficult to describe generic- ally, mainly specialized products of individual manufacturers and which it was felt to be inadvisable to attempt to cover in a standard schedule.

The data has been recast under each alphabetically arranged main heading, through subsidiary headings of diminishing order. The main headings generally denote materials; however, some denote functions, where it is felt that these will be more helpful to the reader. The alphabetical arrangement of main headings has been perpetuated; but it has not been found possible to favour one system universally for the sub-headings where commonness of useagc has in many instances been felt likely to be more useful; whilst dimen-

sional criteria have been applied to headings of lesser orders. The former column headings and rulings have been eliminated as superílous.

The object of the schedule is to standardize the data employed in calculations rather than to provide more exact data for this purpose. The 'standard' weight of a material, as given in the schedule, is not necessarily the mean between the extreme weights, but a fau-average value and may be regarded as sufficiently accurate for general purposes in calculating dead loads in building work. In cases where extreme accuracy is required the actual material to be employed should be weighed and the most adverse conditions of use taken into account,

Wherever possible, a standard weight has been quoted, but in many instances it has been necessary to include tolerances on each side of this figure, There were some cases where, owing to many different densities being produced, often for as many different purposes of equal importance, it was not possible to choose a single notional figure of any particular significance to which tolerances might be applied, and here a range has been given instead.

The committee having in mind the foregoing practical considerations, no weight has been given to more than one decimal place. The use of decimals has been standardized in preference to fractions, for dimensions as well as for weights.

Where maximum and minimum weights are given in this schedule they represent the extremes of the samples investigated and afford some indication of the variations in weights which may be encountered. They should not be taken as the absolute maximum or minimum weights of the material in question.

In preparing this schedule every care has been exercised to ensure that the standard weights represent average materials of normal composition or structure and, where described as 'as laid', íked in the usual manner. In general, weights of appropriate materials relate to a moisture content state of the material when in approximate equilibrium with theexterior atmosphere.

The references to other British Standards given in brackets in the schedule are intended for identification only and are not to be taken to imply that the weights have been derived from the British Standard quoted. Where the standard for the material specifies weights, however, the figures in the schedule have in general been based upon them.

Notwithstanding the .fact that the Fifth Edition of the Standard Method of Measurement of Building Works, which was published during the prepara- tion of the present schedule specifies the yard rather than the foot as the unit of measurement in most Sections, this present schedule standardizes the use of the foot as being most generally useful. The quotation of a 1-inch unit of thickness has, however, been adhered to in general except where a material is normally made principally in much lesser thicknesses.

As altered Oc/. 1968

To help overcome confusion arising from the custom of different industries using different series of thickness gauges (i.e. Birmingham, English Zinc, and Standard Wire) and for the sake of uniformity, the thicknesses in decimals of an inch have been given first in the schedule followed in parentheses by the customary gauge appropriate to the particular material. Only a few typical thicknesses used in building have been given for each material, but the weights uf other gauges may be derived by proportional calculations using the decimal inch equivalents from the tables given in Appendix A.

Where thicknesses of material greater than 1 in are customarily employed but the weights are non-proportional, then the weights of a selection of representative thicknesses have been given.

Some materials are produced in a wide range of sizes, often not solely for building purposes and here, in order to keep the amount of space occupied within reasonable bounds, an attempt has been made to limit the information to representative sizes and, wherever possible, to those most commonly used in building. The space formerly occupied by listing many sizes of some materials has been reduced and information on other entirely different materials substituted to take its place and so increase the general usefulness of the standard. NOTE 1. This standard was prepared in imperial units from which the metric values were derived. Both sets of values are of the same order of accuracy., NOTE 2. The data given in the standard are in units of mass either per unit length, or per

forces in newtons imposed by the dead loads of the materials may be obtained by multiplying unit area, or per unit volume. For most purposes of structural calculation in S1 units the

by 10 (strictly 9.80665) the values given in kilogrammes in the schedule. The degree of approximation implied by this is commensurate with that already indicated in the data given in the schedule, for the reasons explained in the Foreword.
