What are the FDA RH% requirements for Ambient Temperature Warehouses?

FDA recommends a critical\nlimit of 40 ‘F or less. Histamine and/or toxin formation (produced.by\nmicrobial growth) are hazards that can result from exposure to temperatures\nabove 40 ‘F for extended periods of time.

The definition of artificial sweat varies:\n“The one used by the EU (especially for nickel release work) is defined by EN1811 and comprises 0.5% NaCl, 0.1% urea, 0.1% lactic acid and the pH adjusted to 6.6 with NH4OH. However, the ISO standard 3160/2 comprises 20g/l NaCl, 17.5g/l NH4Cl, 5g/l acetic acid and 15g/l d,l lactic acid with the pH adjusted to 4.7 by NaOH.”\nSee the references below:

There is a fairly large variation in what people find to be comfortable, from a low of around 65C for those with high metabolisms or mild hyperthyroidism, to 85 or 90 for those with low metabolism.  The variation for humidity is slightly less, from 30-70%, assuming no physiological problems.  Thus, there is a range, just like any other parameter we live with, like the amount of salt in food, or colors on a wall-there isnt any *one* perfect answer.

ask the suppliers to give you this information if they have not done so already.\nThe manufacturers should/must have and be able to provide this information.

There does not appear to be a specification with that number.\n\nHowever, There is Quality specification: QCI\n\nI suggest that you review: ANSI Y14.5M     This is the most comprehensive tolerance specification.\n\nLink is:\n\nhttp://www.techstreet.com/cgi-bin/detail?\nproduct_id=1527&sid=yahoo&OVRAW=ansi+Y14.5&OVKEY=ansi+y14.5&OVMTC=standard\n\nGood Luck

This involves years and years of development and testing, and unfortunately it can't be stated in just a few paragraphs in a forum like this. I suggest doing some research online for "FDA Approval Process" and "Guidelines," as the paperwork available for this is somewhere in the thousands of pages.

HACCP depends on where you are needing it for. It is different for every place. A resturant would have different HAACCP guidelines than a factory.

The container, because it's in contact with the outside environment, is a heat sink/source and thus it will be at a slightly lower or higher temperature than the solution.

Welding rods are usually sold in air tight containers. Once they are open, the coating will tend to absorb moisture. Any procedure that will exclude atomspheric moisture is okay. \n\nI have seen jobs where they used an old refrigerator with a couple of 100 watts light bulbs inside to maintain some warmth.

Actually, there is an easy way to approximate your answer. A closet should reach steady-state equilibrium before the end of the day - that is, the heat added by the bulb would equal the heat lost by conduction through the ceiling, walls, etc. Once steady-state equilibrium is reached, it doesn't matter what the heat capacity of the air or the closet is - only the thermal conductivity of the walls, door, etc. and the surface area of each will be important.\n\nHere is where effective "R-value" of the walls, ceiling, door, floor is useful. R-value is just the rate of heat transfer in units of K-m^2/Watt (or in British units ft^2 F/(BTU/hr)). The metric "R-value" is about 1/6 of the corresponding R-value in British units due to the conversion factors.\n\nThe formula for difference in heat at steady state (i.e., heat rise) would be approximately:\n\nDelta-T = 100 Watts / (R1A1 + R2A2 + R3A3 + R4A4 + R5A5 + R6A6) where each of the 6 surfaces of the room are treated separately. \n\nYou need to know approximately what your insulation is for each surface - but a little research on the internet and comparison based on your closet's insulating properties should get you a halfway decent approximation.

Well you could do check the below web sites and with respect to USA you must have clearances from the FDA.

Go to the Manufacturerr's Website, should be listed on package or bottle.  If not, Google the Mfr Name.\n\nOn their website, do search on MSDS <item name>\n\nMay be PDF, sometimes they will mail it, especially if you tell them you are a good customer.
