81 cubic feet at 60 deg. F. and
30 inches per lb.). A margin of 2 per cent. shall be allowed for the
analysis. Carbide which yields less than 300 litres per kilogramme, but
not less than 270 litres (= 4.33 cubic feet) of crude acetylene per
kilogramme (with the above-stated 2 per cent. margin for analysis) must
be accepted by the buyer. The latter, however, is entitled to make a
proportionate deduction from the price and also to deduct the increased
freight charges to the destination or, if the latter is not settled at
the time when the transaction is completed, to the place of delivery.
Carbide which yields less than 270 litres of crude acetylene per
kilogramme need not be accepted.
"Carbide must not contain more than 5 per cent. of dust. By dust is to be
understood all which passes through a screen of 1 mm. (0.04 inch) square,
clear size of holes.
"Small carbide of from 4 to 15 mm. (= 1/6 to 3/5 inch) in size (and
intermediate sizes) must yield on the average for each delivery at least
270 litres at 15 deg. C. and 760 mm. pressure of crude acetylene per
kilogramme (= 4.33 cubic feet at 60 deg. F. and 30 inches per lb.) A margin
of 2 per cent.
