§ Mr. Marplesasked the Minister of Works what proportion of B.S. 1010 taps and Ministry of Health "Swan" taps, respectively, are used in the home market; if he will give an estimate of what percentage saving of brass would be achieved if the lighter "Swan" tap were used instead of the B.S. 1010; and what technical reasons there are why "Swan" taps should not be used.
§ Mr. StokesI have no figures to show the proportions of B.S. 1010 and Ministry of Health "Swan" taps used on the home market. It is estimated that the latter are about 7 per cent. lighter than the B.S. 1010. I should hesitate to advance technical reasons why a tap specified by the British Standards Institution should be superseded by an earlier model. The matter is, however, being considered.
