Testing at high temperatures can prove to be erroneous if you begin testing before things have stabilized. When you first turn on your chamber, the load string and temperature are not stabile. A transient temperature will cause your signal to drift and show a load when there isn’t one. Just like preheating your oven before cooking, you need to allow your load string to warm up and stabilize, as well as reaching your desired temperature before placing your specimen within the grips – this will give you accurate data.
Side tip: We have found that HVAC systems or other types of vents can impact your temperature testing. Make sure to move your system away from vents before testing at high temperatures.
