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.
