==Definitions in science and industry== Temperature ranges are defined as ''room temperature'' for certain products and processes in industry, science, standards, and consumer goods. For instance, for the shipping and storage of [[pharmaceuticals]], the [[United States Pharmacopeia]]-National Formulary (USP-NF) defines ''controlled room temperature'' as between {{convert|20|and|25|C}}, with excursions between {{convert|15|and|30|C}} allowed, provided the [[mean kinetic temperature]] does not exceed {{convert|25|C}}.<ref name="USP 2017">{{Cite web |url=http://www.uspnf.com/sites/default/files/usp_pdf/EN/USPNF/revisions/659_rb_notice.pdf |title=General Chapter < 659> Packaging and Storage Requirements |date=1 May 2017 |website=[[United States Pharmacopeia]] |access-date=2018-04-04}}</ref> The [[European Pharmacopoeia]] defines it as being simply {{convert|15|to|25|C}}, and the [[Japanese Pharmacopeia]] defines "ordinary temperature" as {{convert|15|to|25|C}}, with room temperature being {{convert|1|to|30|C}}.<ref name="ECA 2017">{{Cite web |url=https://www.gmp-compliance.org/gmp-news/what-are-the-regulatory-definitions-for-ambient-room-temperature-and-cold-chain |title=What are the regulatory Definitions for "Ambient", "Room Temperature" and "Cold Chain"? |date=2 March 2017 |website=ECA Academy |access-date=2018-04-04}}</ref><ref name=Chow2007a>{{cite book|url=https://books.google.com/books?id=x9XccGzr4wIC&q=%22room+temperature%22+definition&pg=PA7|title=Statistical Design and Analysis of Stability Studies|author=Shein-Chung Chow|publisher=[[CRC Press]]|year=2007 |series=[[Chapman & Hall]]/[[CRC Press|CRC]] [[Biostatistics]] Series|access-date=4 April 2018 |isbn=9781584889069|page=7|quote=1.2.3.3 Definition of Room Temperature: According to the ''United States Pharmacopeia National {{sic|Forumlary|expected=Formulary}} (USP-NF)'', the definition of room temperature is between 15 and 30 °C in the United States.
