Autoinfiammabilità

21:24 Jul 8, 2007 

I am translating a number of MSDSs, and the following have autoflammability data. Flash point in not listed for any of the chemicals. All are in powder form.

5-FLUOROURACIL 283°C
CHLORAMPHENICOL SUCCINATE Probable at temperatures greater than 140°C;
NICERGOLINE 360°C (in nube)

Flash point / flammability: Julianne: What is the chemical? The temperature?
The flash point of a fuel is the lower flammability temperature of the fuel under the specific test conditions. However, this is not necessarily the lower flammability temperature under other conditions, such as in an aircraft fuel tank.

Thus, I would think that texjax had the correct translation...

Julianne: In the following MSDS Sheet, there is a temperature after autoflammability. Also, note that there are two Temps: flash point (also known as ignition poiint - just for starting combustion) and flammability point (sustaining it). I will list it..

Thanks so much, Zareh!

17:14 Jul 8, 2007 

Julianne: I will look into this further... I may also be able to confirm this with staff responsibile for safety here in our chemistry department at the University of Delaware, tomorrow, Monday... Will let you know...

Interesting clarification, Zareh. Well, in my specific case, the term appears on an MSDS under Physical and Chemical Properties. And beside the term, a temperature is specified. Do you think this means the temp. at which the substance starts to burn or the temp. at which it continues buring once it has started? TIA

Ignitability has to do more with the **starting** of the burning. Flammability has to do with both the **starting** and the **supporting** of combustion.

16:59 Jul 8, 2007 

Yes, Julianne: if the emphasis is on "the beginning of burning", then autoignitability is an option. However, if the emphasis is on the beginning and cnotinuation of burning, the the approriate term is ** autoflammablity**.

16:46 Jul 8, 2007 

I have also found 'autoignition temperature' in several MSDS glossaries and in Wikipedia. This may be a viable alternative.

18:15 Jul 7, 2007 

Very welcome, Julianne!

18:05 Jul 7, 2007 

Zareh, Thanks for your comments and reference. I was originally thinking of rewording to something along the lines of 'Self-combustible at temperature x' because, as Jim mentioned, Italian uses nouns more often than English. However, after seeing texjax's suggestion and actually finding an earlier proz query for autoflammability, there is no doubt that this is the correct answer.

18:00 Jul 7, 2007 

Sorry, it is the ** 2nd listing **, not the third.

17:57 Jul 7, 2007 

Julianne: The reference I provided in connection with texjax's answer is from an msds sheet... It's the third entry on the list of Google references.

17:53 Jul 7, 2007 

You mean self-combustibility... don't think however that this is the best choice...

21:23 Jul 6, 2007 

Actually, 'self-combustible' might be it.
