The USP Controlled Room Temperature is a series of United States Pharmacopeia guidelines for the storage of pharmaceuticals; [1] the relevant omnibus standard is USP 797. [2] [3] Although 100% compliance remains challenging for any given facility, [4] the larger protocol may be regarded as constituting a form of clean room [5] which is included in a suite of best practices .
Room temperature. Mercury-in-glass thermometer measuring an ambient temperature of 23 °C (73 °F) a little above the room temperature range. Room temperature, colloquially, denotes the range of air temperatures most people find comfortable indoors while dressed in typical clothing. Comfortable temperatures can be extended beyond this range ...
An operating temperature is the allowable temperature range of the local ambient environment at which an electrical or mechanical device operates. The device will operate effectively within a specified temperature range which varies based on the device function and application context, and ranges from the minimum operating temperature to the ...
In industry and commerce, the standard conditions for temperature and pressure are often necessary for expressing the volumes of gases and liquids and related quantities such as the rate of volumetric flow (the volumes of gases vary significantly with temperature and pressure): standard cubic meters per second (Sm 3 /s), and normal cubic meters per second (Nm 3 /s).
The temperature at which limestone yields calcium oxide is usually given as 825 °C, but stating an absolute threshold is misleading. Calcium carbonate exists in equilibrium with calcium oxide and carbon dioxide at any temperature. At each temperature there is a partial pressure of carbon dioxide that is in equilibrium with calcium carbonate.
In aviation, stagnation temperature is known as total air temperature and is measured by a temperature probe mounted on the surface of the aircraft. The probe is designed to bring the air to rest relative to the aircraft. As the air is brought to rest, kinetic energy is converted to internal energy. The air is compressed and experiences an adiabatic increase in temperature. Therefore, total ...
Scale of temperature Scale of temperature is a methodology of calibrating the physical quantity temperature in metrology. Empirical scales measure temperature in relation to convenient and stable parameters or reference points, such as the freezing and boiling point of water. Absolute temperature is based on thermodynamic principles: using the lowest possible temperature as the zero point, and ...
The average annual temperature in the mainland varies from less than 2.5 °C (36.5 °F) in the north of the Pyrenees, close to the border with France, to more than 20 °C (68 °F). on a small region of Mediterranean coast on Almeria and Granada provinces. [5] [6] The annual average precipitation ranges from more than 2,200 millimetres (87 in) on the northwest of Galicia and in the Pyrenees ...
