266 (1) Subject to subsections (4) and (5), the limits of error set out in the tables to subsections (2) and (3) apply to all positive displacement bulk volumetric liquid meters, including vehicle-mounted meters, that are designed to measure volumes of 180 litres or more, or 40 gallons or more, of refined petroleum products such as gasoline and fuel oils, foodstuffs such as milk, liquid fertilizers of the solution type such as aqua ammonia, or other liquids of low viscosity.
(2) The limits of error set out in the following table apply to meters, generally of a size 65 mm or 2½ inches or smaller that are designed to measure liquids of low viscosity:
TABLE
Column I Column II Column III Item Known Test Quantity Acceptance Limits of Error In-Service Limits of Error 1 Any volume of 225 litres or more up to 900 litres or of 50 gallons or more up to 200 gallons 3/16% of known test quantity ¼% of known test quantity (3) The limits of error set out in the following table apply to meters, generally of a size 75 mm or three inches or larger that are designed to measure liquids of low viscosity:
TABLE
Column I Column II Column III Item Known Test Quantity Acceptance Limits of Error In-Service Limits of Error 1 Any volume of 1 350 litres or more or of 300 gallons or more 1/8% of known test quantity ¼% of known test quantity (4) The acceptance limits of error and in-service limits of error set out in the tables to subsections (2) and (3) apply to known test quantities equal to or greater than that delivered by the meter in one minute at the maximum operating rate.
(5) The acceptance limits of error set out in Column II of the tables to subsections (2) and (3) apply only to tests made under controlled conditions such as bench tests and, for tests for acceptance limits of error under other conditions, the limits of error set out in Column III of those tables shall apply.
