MMPDS Room Temperature
MMPDS Room Temperature
(OP)
Anyone know, or have better eyes than I do, as to whether the MMPDS uses a standard value for room temperature?
- I can't find it defined anywhere in the opening chapters,
- nor is it defined per material,
- nor does it appear to be ISA value of 15°C (eg. Figure 3.2.4.0(a) showing temperature depended data for Al2024 seems to indicate a transition point at 90°F / 32°C, but doesn't specify it explicitly, while Figure 3.2.4.1.1(a) seems to indicate 80°F / 27°C).
It seems like a stupid question, but I can't for the life of me find a definition anywhere...
Would definitely appreciate anyone's insights.

Testing for all material values [mechanical, environmental, etc] is accomplished [mostly] per ASTM methods. I am dead certain... without looking... that ASTM has the definitions You are looking for.
NOTE. Values between 60-to-80F... which most of us in the US would use as 'typical RT rule-of-thumb'... are typically uniform/flat... with insignificant variations in metals for at least another +/-30F. probably more differences in the test equipment set-up and calibrations [for variations due to expansion/contraction/calibration of mechanical and electronic gages].
