When entering new questions, KudoZ askers are given an opportunity* to classify the difficulty of their questions as 'easy' or 'pro'. If you feel a question marked 'easy' should actually be marked 'pro', and if you have earned more than 20 KudoZ points, you can click the "Vote PRO" button to recommend that change.
How to tell the difference between "easy" and "pro" questions:
An easy question is one that any bilingual person would be able to answer correctly. (Or in the case of monolingual questions, an easy question is one that any native speaker of the language would be able to answer correctly.)
A pro question is anything else... in other words, any question that requires knowledge or skills that are specialized (even slightly).
Another way to think of the difficulty levels is this: an easy question is one that deals with everyday conversation. A pro question is anything else.
When deciding between easy and pro, err on the side of pro. Most questions will be pro.
* Note: non-member askers are not given the option of entering 'pro' questions; the only way for their questions to be classified as 'pro' is for a ProZ.com member or members to re-classify it.

Jun 1, 2016 - Lowering the air temperature to the dew point - ie below which condensation or precipitation occurs - produces a relative humidity of 100%. ... What is the relative humidity [%] for non-condensing at 55 degrees Celsius and at 60 degrees Celsius? ... Can water condense when the relative ...

: I can't access the Quora ref., but that extract doesn't seem to make sense. However, I now realise that this is not about the RH per se, but the potential interaction between a given RH (80%) air temp. and any surface cold enough for condensation to form.

with free of moisture
I’d say it would be difficult to keep the stored item moisture free if the ambient humidity goes up to 80%. Perhaps they used some kind of desiccants to absorb moisture in the package.

: Apart from the fact that this EN is even less understandable than the original, this is not what it is about: this term specifically refers to the humidity being 'non-condensing' as I have explained above.

Storage humidity: maximimum 80% relative humidity
| Thank you very much for your support,B D Finch :) |

: I'm afraid this misses out the specific point of 'non-condensing'. Please trust me on this, these are specific technical points, and RH and 'non condensing' are 2 associated but separate concepts. at 80% RH, it may be condensing or non-condensing.

It doesn't, because if the relative humidity is 80% there won't be condensation. Stating the maximum relative humidity level would be far more natural in this context than referring to non-condensing moisture in the air.

: there are two separate requirements (1) "max humidity 80%" AND (2) whatever is the humidity there shouldn't be any condensate on the walls of the fridge / cold room

(1) It's "relative humidity", (2) there's a direct link between relative humidity and condensation.// Agreed: see my comment to Tony in the Discussion.

with no liquid from condensation

: Not the meaning of this quite specific technical terminology in this context. / It's not my "opinion" — this is well-known EN technical terminology to anyone familiar with the field.

But I can assure you that in specifications and the like, we DO talk about "X% RH, non-condensing" — of course it is the implied 'humidity/moisture' that might or might not condense; not the dimensionless abstract notion of 'RH'.
I have written and/or had to comply with masses of these specifications, and I am intimately familiar with this terminology.
"The RH is NOT the dewpoint divided by the temperature. For example, if the temperature was 60 F and the dewpoint was 30 F, you would not simply take (30/60)*100% = 50% RH.
"Method #1
"When given temperature and dewpoint, the vapor pressure (plugging Td in place of T into Clausius-Clapeyron equation) and the saturation vapor pressure (plugging T into Clausius-Clapeyron equation) can be determined. The RH = E/Es*100%.
Clausius-Clapeyron equation:
"LN(Es/6.11) = (L/Rv )(1/273 - 1/T)
Es = Saturation vapor pressure
L = Latent heat of vaporization = 2.453 × 10^6 J/kg
Rv = Gas constant for moist air = 461 J/kg
T = Temperature in Kelvins"

I think the term they were trying to use was 'non-condensing' — this is a standard term used in connection with Relative Humidity, you can easily check it out for a technical explanation; I think it basically means that at higher humidity levels, the moisture in the air is not tending to dondense out (form condensation).
