Instron's (Norwood, Mass.) ETMT 8800 is a multifunctional test system for conductive materials used in industries ranging from metal processing and production to advanced aerospace engineering. It measures mechanical and physical properties and microstructural stability under thermal exposure. The unit design is similar to the company's 8800 digital controller, a Microtester test frame. Combined with a direct resistance heating system, it offers full reverse stress loading to 3 kN and thermomechanical capabilities up to 1500°C/2732°F. It reportedly provides rapid, cost-effective assessment of materials that are in short supply and/or extremely expensive. Using miniature test articles, the unit can achieve fatigue loading rates for 20 N/sec to 1,000 N/sec and heating rates up to 200°C/sec (392°F/sec).
