Table 2 Summary of standard tests performed during one set of parabolas

From: Hydrogel mechanical properties in altered gravity

Parabola

No. of tests/parabola

Procedure

Technical details

1 to 4

2 tests:

1 test in 1.8g0

1 test in µg0

During each test, the sample is loaded up to max force. When this is reached, the sample is unloaded. The test starts and finishes in the same gravity.

Testing speed 2 mm/min.

Force range: 0–1.5 N

5

1 test overall

The test starts at 1.8g0 and ends at µg0. The sample is loaded up to max force, and then unloaded. Curves include gravity transition.

Testing speed 2 mm/min

Force range: 0–6.5 N
