  2. Conversion of scales of temperature - Wikipedia

    en.wikipedia.org/wiki/Conversion_of_scales_of...

    Converting units of temperature differences (also referred to as temperature deltas) is not the same as converting absolute temperature values, and different formulae must be used. To convert a delta temperature from degrees Fahrenheit to degrees Celsius, the formula is {ΔT} °F = ⁠ 9 / 5 ⁠ {ΔT} °C.

  3. Danger zone (food safety) - Wikipedia

    en.wikipedia.org/wiki/Danger_zone_(food_safety)

    Food safety agencies, such as the United States' Food Safety and Inspection Service (FSIS), define the danger zone as roughly 40 to 140 °F (4 to 60 °C). [1] [2] [3] The FSIS stipulates that potentially hazardous food should not be stored at temperatures in this range in order to prevent foodborne illness [a] and that food that remains in this ...

    The Food Safety (Temperature Control) Regulations 1995 Description English: These Regulations implement paragraphs 4 and 5 of Chapter IX of the Annex to Council Directive 93-43-EEC of 14th June 1993 on the hygiene of foodstuffs, as well as containing certain national provisions relating to food temperature control.

  5. Scale of temperature - Wikipedia

    en.wikipedia.org/wiki/Scale_of_temperature

    The degree Celsius (°C) can refer to a specific temperature on the Celsius scale as well as a unit to indicate a temperature interval (a difference between two temperatures). From 1744 until 1954, 0 °C was defined as the freezing point of water and 100 °C was defined as the boiling point of water, both at a pressure of one standard atmosphere.

  6. Fahrenheit - Wikipedia

    en.wikipedia.org/wiki/Fahrenheit

    A temperature interval of 1 °F was equal to an interval of 5 ⁄ 9 degrees Celsius. With the Fahrenheit and Celsius scales now both defined by the kelvin, this relationship was preserved, a temperature interval of 1 °F being equal to an interval of 5 ⁄ 9 K and of 5 ⁄ 9 °C. The Fahrenheit and Celsius scales intersect numerically at −40 ...

  7. Potentially Hazardous Food - Wikipedia

    en.wikipedia.org/wiki/Potentially_Hazardous_Food

    Potentially Hazardous Food has been redefined by the US Food and Drug Administration in the 2013 FDA Food Code to Time/Temperature Control for Safety Food. [1] Pages 22 and 23 (pdf pages 54 and 55), state the following: PHF table A 2013 FDA Food Code. PHF table B 2013 FDA Food Code.

  8. Iron(I) hydride - Wikipedia

    en.wikipedia.org/wiki/Iron(I)_hydride

    Molecular FeH can also be obtained (together with FeH 2 and other species) by vaporizing iron in an argon-hydrogen atmosphere and freezing the gas on a solid surface at about 10 K (-263 °C). The compound can be detected by infrared spectroscopy , and about half of it disappears when the sample is briefly warmed to 30 K. [ 15 ] A variant ...

    An example SDS, including guidance for handling a hazardous substance and information on its composition and properties. A safety data sheet (SDS), [1] material safety data sheet (MSDS), or product safety data sheet (PSDS) is a document that lists information relating to occupational safety and health for the use of various substances and products.
