sample limits
TMA 402 proposes sample limits as to length (convetionally Z axis) but limits in x and y. Can be known?

This depends on the mode.
Sample holder systems, interchangeable:
- Materilas: Fused silica (up to 1000°C) and Al2O3 (1550°C) for the
- Modes: expansion, penetration, 3-point bending, tension
Sample length (max.): 30mm (10 and 20 mm free bending length for 3-point bending)
Automatic length determination:
- Yes, in expansion and penetration mode
- Option in tension mode (reference sample required)
- Not in Bending mode
Sample diameter (max.):
12 mm (10 mm for Al2O3 fixtures)
Hope that helps.
Thanks to Geyer
It has been really hepful
Dear friends;
Using TMA 402 and considering z // the force axis and x=y=a the sides of the section or base of sample, I ask: Is there any tip or recomendation for z/a (aspect ratio) of the sample for penetration and expension mode ? Is there any for tension mode. ?
Sample fixture set for expansion measurements in the temperature range from -150 to 1000 °C. Maximum sample dimensions|30mm, Ø 12 mm.
Sample fixture set for penetration measurements in the temperature range from -150 to 1000°C. Maximum sample dimensions |30mm, Ø 12 mm.
Thanks once again to colleague Geyer
