3、onAmd. No. Date CommentsThis British Standard was published by BSI. It is the UK implementation of EN 14035-38:2006. It partially supersedes BS 7114-2:1988 and BS 7114-3:1988, which have been declared obsolescent. NOTE BS 7114-2:1988 and BS 7114-3:1988 are cited in The Fireworks (Safety) Regulations

4、 1997. The UK participation in its preparation was entrusted to Technical Committee CII/47, Fireworks. A list of organizations represented on this committee can be obtained on request to its secretary. The United Kingdom, as a member of CEN, is obliged to publish EN 14035-38 as a British Standard. H

5、owever, attention is drawn to the fact that the United Kingdom voted against the approval of EN 14035-38. One of the main reasons for this disapproval is that BSI Committee CII/47 considers that Figure 4 in 8.7 is misleading because various elements of the figure are too small. The BSI Committee is

6、of the opinion that if a transparent template is used to check type sizes on labelling, the template should be produced to a level of accuracy that will permit the height of each character and symbol on the template to be within mm of the relevant minimum height specified in this standard. 0.10+This
