242. The rated maximum flow of a meter shall be such that, when it is tested using refined petroleum products with normal lubricating properties such as kerosene or fuel oil, the meter will measure accurately without abnormal wear, and the meter shall be de-rated if necessary for use on products with lesser lubricating properties.

262. When a meter is tested for in-service limits of error at any flow rate between its rated maximum flow and its rated minimum flow using a known test quantity of liquid set out in Column I of an item in the applicable table to sections 265 to 270, the meter is within the in-service limits of error in respect of that quantity if the quantity registered by the meter does not differ from the known test quantity by an amount in excess of the amount set out in Column III of that item.

261. When a meter is tested for acceptance limits of error at any flow rate between its rated maximum flow and its rated minimum flow using a known test quantity of liquid set out in Column I of an item in the applicable table to sections 265 to 270, the meter is within the acceptance limits of error in respect of that quantity if the quantity registered by the meter does not differ from the known test quantity by an amount in excess of the amount set out in Column II of that item.
