| Cubical coefficient of thermal expansion: Three dimensional expansion or contraction of a material due to temperature change, expressed °C"1 or °F"1 Field standard test measure: A measure that can be hand held and is usually less than 40 Liters {10 Gallons). "High Resolution" standard: A standard with a small diameter neck for improved resolution in reading the meniscus. Generally used in the laboratory as a standard or check standard for measurement control of a primary standard. Main flow cessation: The moment when a full discharge stream "breaks" and becomes a trickle or a drip. Prover: Bottom drain Is implied. Filled from the top or bottom loading, depending on intended use. May be free standing, mounted permanently, or on truck or professional trailer and not hand held. Reference temperature: The temperature at which the measure is intended to contain or to deliver its nominal capacity. Sight-flow-indicator: A professional fitting with windows to visually observe the flow through a pipe. Submerged fill pipe: Pipe used in top filling to minimize foaming of liquids, such as fuel oil and milk, by discharging the product into the bottom of a prover. To contain: An indication that the standard is adjusted to contain its intended volume when filled from its empty condition at a reference temperature, (the empty condition is "dry" and test measures or provers are generally not used in this condition). To deliver: An indication that the standard is adjusted to deliver its intended volume at a reference temperature. Provers used in a "wet" condition are marked To Deliver. Tolerance: Maximum permissible error. A value fixing the limit of allowable error or departure from the true performance or value. Vapor recovery: A system for entrapping and collecting vapors for return to the tank to prevent expulsion into the atmosphere.
