What gets hot, must get cold. This is something that people neglect or negate to think about when it comes to temperature testing.
We consider if it needs to be cooled rapidly; can we use chilled water? Do we have chilled water available or is that something else we are going to need to add to the lab or wherever we’re doing the testing.
If we’ve got a sample that’s being tested in an environmental chamber, then we have to think about getting to the outside of that sample to use forced air cooling, so we might have to do the cooling through the centre of the sample.
We can use forced air or chilled water. But then we will have to consider the loading bars and gripping design to enable us to get that into the centre of the sample.
So, if we are trying to design a testing programme then then we need to think all the way back to how is that going to affect what we are trying to achieve.
If we do not need to cool the sample and we are doing elevated temperature testing, there is a high probability that we are going to need to cool the grips, the load cell, the loading bars.
So, we might not actually have to do specific cooling of the sample itself, but we are going to have to think about the bigger picture and the assembly as a whole.
