Whether you’re testing the ceramics used in wind turbine blades for power generation or the metal used in a jet engine, high-temperature tests present some unique challenges and require specialized testing equipment and accessories.
Do I need a Chamber or a Furnace?
Do I need an Extensometer and What Kind?
Do I need a Chamber or a Furnace?
- Temperature chambers are used up to 600o C (1112o F) – this is when the wavelength of the electromagnetic radiation heat energy reaches the visible spectrum.
- Split-furnaces are used for testing between 400o C and 1200o C – this is when radiative heat transfer becomes greater then convective. Models are also available that apply heat (up to 1600°C) only to the specimen, and not the grips.
Do I need an Extensometer and What Kind?
- Various types of extensometers can be attached to the specimen before or after heat soaking.
- Water cooled extensometers are available if your test requires accurate strain measurement at very high temperatures.
- Alignment of the load string is very important and easily achieved with self-aligning quick-change adapters. These adapters allow quick and efficient removal of the tested specimen and pullrods so a new specimen can be promptly installed and tested.
- Round specimens with threaded ends or flat, pin-loaded specimens are ideal for high temperatures.
- High-temperature lubricant is necessary on all threaded connections.
