When a product says "refrigerate" or "freeze", the temperature they're asking you to keep it at is not a mystery -- most refrigerators and freezers maintain an expected temperature range. But other products indicate "room temperature" or that they should be stored in a "cool, dry place". Are there actual temperature ranges associated with these set phrases? I grew up in North America, in a household where we couldn't afford to overly heat the house in the winter, or cool it in the summer. "Room temperature" was, therefore, 50-55°F (10-12.7°C) in the winter, and 85-90°F (29-32°C) in the summer. My perception of "room" temperature is similarly skewed -- this isn't at all "normal" from a N. American perspective, where most of my peers like to keep their houses at around 77°F/25°C in the winter, and 67°F/19°C in the summer. But I remain confused, at least, from a culinary perspective of what exactly I'm being asked when a product indicates these set phrases. As a concrete example: I recently bought a tub of ghee. It indicates to me on the labelling that it does not require refrigeration, can be kept at "room temperature", and should be stored in a "cool, dry place". My apartment is 80°F/26.6°C right now -- is this "room temperature"? (It'll cool to ~61°F/16°C overnight.) In the meantime, it's significantly warmer than the store shelf I bought it from, and the ghee has gone from a soft solid to pure liquid. This change of state (solid -> liquid) is what prompted my concern that I'm misinterpreting "room temperature" in terms of food temperature and safety. 
"Room temperature" as used for testing, analysis, and validation purposes generally falls within the range of 65F-75F (18C-24C). Published research will typically specify temperature ranges used. Both the FDA Food Code (2017) and Canadian Food Retail and Food Services Code (2016), providing guidelines for inspection activities, take an outcome-based approach and do not reference specific storage temperatures or humidity levels as products stored unopened in these conditions are designed to be safe or are self-evident if spoiled/unsafe - mouldy potatoes, rusted or swollen cans, etc. In most jurisdictions in North America, refrigerator and freezer temperature conditions are often codified in laws and may be required to be explicitly labelled for consumer protection since pathogen activity is not as readily evident as spoilage - some Listeria, for example, can reproduce in food below 40F/4C, making both maximum storage temperature and duration needed. A better source for optimum room temperature conditions would be your local building code, though most will specify the same range noted above and humidity <60%. If it's comfortable for humans, it's most likely suitable for products designed for those conditions. For your ghee example - it originates in India for preserving butterfat at 30C+ temperatures and seasonal relative humidity close to 100%. When properly stored in an airtight container there is no water available for microorganism activity, and the concern is more for long-term quality decline due to oxidative rancidity.
