HC Deb 30 July 1954 vol 531 c130W
Mr. Harold Davies

asked the Minister of Transport and Civil Aviation what further inquiries have been made into the growing incidents of frosted windscreens; and what approaches have been made to manufacturers.

Mr. Molson

So far as I am aware, the number of incidents involving shattered windscreens is not on the increase. The British Standards Institution last May amended their specification of "Safety Glass for Land Transport," to which manufacturers of toughened glass in this country work, partly to provide for better visibility if the glass is fractured. Glass made to this specification breaks into appreciably larger particles than under the specification previously ruling, and the visibility is correspondingly improved. My Department is in continual touch with manufacturers on this subject.
