12、ements and Components (of Diverse Materials) for Buildings Standards Committee. It supersedes BS5051-1:1973 which is withdrawn. The title has been changed to distinguish bullet-resistant glazing from other kinds of security glazing, such as anti-bandit glazing resistant to manual attack (covered by
13、BS5544:1978). Major changes include the introduction of a new category of glazing designed to protect against attack by a5.56mm calibre rifle, reclassification of the old G3 grade as R2 (designed to protect against attack by a7.62mm calibre rifle), and the introduction of a revised test for glazing
14、resistant to shotgun attack. Other changes include the deletion of imperial equivalent dimensions, the omission of barrel length requirements for test weapons, and the deletion of the old Appendix C (which gave details of specific systems of bullet velocity measurement). General information on veloc
15、ity detection methods now appears in the notes toTable 1, and adjustments have been made to the tolerances on striking velocities. Background information in the foreword of the last edition has been transferred to an introduction (see clause0). Requirements for through-vision and light transmission
16、have been removed from the specification. The committee considered it inadvisable to draw up detailed specifications for each type of bullet-resistant glazing known to be satisfactory because: a) these could not replace performance tests, and b) the subject continues to be in an active stage of deve
17、lopment and it would be extremely difficult to keep such specifications comprehensive and up-to-date by including the new or improved materials that are becoming available or will do so in future. Correct installation of bullet-resistant glazing is considered to be vital to its effectiveness. Attent
18、ion is therefore drawn to BS5357 which covers installation of security glazing, and toAppendix C of this standard, which details some essential installation requirements. This British Standard calls for the use of procedures that may cause injury if adequate precautions are not taken. It refers only
19、 to technical suitability and does not absolve the user from legal obligations relating to health and safety at any stage. 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 w
20、ith 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, pages i and ii, pages1 to6, an inside back cover and a back cover. This standard has been updated (seecopyright date) and may have had amen
21、dments incorporated. This will be indicated in the amendment table on theinside front cover.BS5051-1:1988 BSI 01-1999 1 0 Introduction 0.1 Designation system In considering the various types of potential attack against which bullet-resistant glazing may be required to provide protection, it has been
22、 found convenient to define six categories of glazing, to be designated by code letters and numbers (see clause3). 0.2 General requirements The first requirement for bullet-resistant glazing is that it will provide protection by preventing the passage of projectiles from various types of weapon. The
23、 second requirement is that it will protect personnel against injury from splinters of glass which may be ejected from the rear surface when the glazing is attacked. Because of the need to comply with this second requirement, the glazing may be either a unitary type or a duplex type in which a prima
24、ry screen stops the bullet and a thin, secondary screen stops flying splinters. In a duplex installation the secondary screen is permanently fixed, for example, by hanging on chains from the ceiling, and is not necessarily attached directly to the main screen. 0.3 Service life Some types of bullet-r
