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.
In contrast, ambient temperature is the actual temperature, as measured by a thermometer, of the air (or other medium and surroundings) in any particular place. The ambient temperature (e.g. an unheated room in winter) may be very different from an ideal room temperature. Food and beverages may be served at "room temperature", meaning neither ...
USP establishes documentary (written) and reference (physical) standards for medicines, food ingredients, dietary supplement products, and ingredients. These standards are used by regulatory agencies and manufacturers to help to ensure that these products are of the appropriate identity, as well as strength, quality, purity, and consistency.
The refrigerator should maintain a temperature between 2° and 8 °C (36° and 46 °F). Freezers should maintain a temperature between -50° and -15 °C (-58° and +5 °F). [14] Thermometers are useful to monitor the temperature by placing at the storage unit's central location, adjacent to the vaccines.
The U.S. Pharmacopeia (USP/NF) defines several terms relating to the storage of pharmaceutical products. 20°C to 25°C (68°F to 77°F) is given as the definition of "controlled room temperature", and you will see this listed on many pharmaceutical products. "Warm" is defined as any temperature between 30°C and 40°C (86°F and 104°F).

Tablet formulations are designed and tested using a laboratory machine called a Tablet Compaction Simulator or Powder Compaction Simulator. This is a computer controlled device that can measure the punch positions, punch pressures, friction forces, die wall pressures, and sometimes the tablet internal temperature during the compaction event.
Air temperature and humidity levels inside a cleanroom are tightly controlled, because they affect the efficiency and means of air filtration. If a particular room requires low enough humidity to make static electricity a concern, it too will be controlled by, e.g., introducing controlled amounts of charged ions into the air using a corona ...
