i

save as provided in sub-paragraphs (ii) and (iii), measuring equipment which is constructed to continuously meter liquid shall be tested by its providing a minimum delivery of the test liquid or a delivery which the inspector specifies and which he considers to be sufficiently close to a minimum delivery and additionally in either case by its delivery of both 10 and 20 litres of test liquid;

b

so that the speed of operation in respect of any individual delivery is as uniform as practicable; and
