BS7114 has been prepared in order to specify certain basic requirements for the constr

8、uction and performance of fireworks (as well as describing an associated classification system and methods of test) which will help to ensure that the risks of injury to users, onlookers and the public in general and of damage to property are minimized. It also includes requirements for labelling in

9、 order to encourage the proper use of fireworks. Prior to the publication of BS7114 there had been no comprehensive document published in the United Kingdom concerned with the quality of fireworks, although fireworks are subject to certain legislation, notably the Explosives Act1875 and the Firework

10、s Act1951, and to voluntary agreements between Government departments and the industry. BS 7114 is issued in three Parts as follows: Part 1: Classification of fireworks; Part 2: Specification for fireworks; Part 3: Methods of test for fireworks. The main purpose of this Part of BS7114 is to provide

11、the classification of fireworks which is used as the basis of the requirements specified in Part2 and the methods of test described in Part3. It also defines various terms which appear in one or more of the Parts of BS7114. Attention is drawn to the United Nations classification scheme, published in

12、 the “Recommendations on the Transport of Dangerous Goods”, in which products as packaged for transport are assigned to a class and division dependent on the hazard they present. Information and guidance on the classification and marking of fireworks which are outside the scopes of BS7114-2 and BS71

13、14-3 are given in Appendix C. 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. In particul

14、ar, attention is drawn to the Explosives Act 1875 and Order in Council 15, the Explosives Act 1923, the Fireworks Act 1951, the Health and Safety at Work etc. Act 1974 and the Consumer Protection Act 1987. Summary of pages This document comprises a front cover, an inside front cover, pages i and ii,

15、 pages1 to 8, an inside back cover and a back cover. This standard has been updated (see copyright date) and may have had amendments incorporated. This will be indicated in the amendment table on theinside front cover.BS7114-1:1988 BSI 02-1999 1 1 Scope This Part of BS7114 establishes a system for t
