  •  (1) Subject to subsection (7), the limits of error set out in the tables to subsections (2) to (6) apply in respect of all meters that are designed to measure liquefied gases at ambient temperatures.

  • (2) The limits of error set out in the table to this subsection apply in respect of meters of a size from 25 mm to 50 mm or one inch to two inches, when tested using the liquefied gases the meters are intended to measure and using a narrow neck metal standard of the vapour displacement type.
