Unique Testing Features at Joliet Metallurgical
Laboratories, Inc.

	JML has been in business since 1956, specializing in Low Stress Ground Specimen Preparation, Tensile, Stress-Rupture, Creep, and Creep-Rupture testing.
	JML has been NADCAP approved since 1994.
	JML is the largest laboratory of its kind with approximately 400 test stands capable of Stress-Rupture, Creep, and Creep-Rupture testing from room temperature to 2200ºF.
	JML is uniquely qualified to test the most advanced materials, including single crystal alloys.
	JML uses a continuous looped system to control test temperature per ASTM and verifies each test - each shift using a manual digital meter to avoid possible test temperature errors.
	JML uses dual measuring instrumentation extensometers with computer averaging, not mechanical averaging, for greater precision at low strain rates.
	JML has Creep and Stress-Rupture tests that have been “in test” for over five years. As we also specialize in long term testing, JML uses special gages to avoid any “drift” problems associated with all electronic LVDT and capacitance transducers.
	JML has automatic electrical power back up in case of a power failure.
	JML supplies all data in electronic format for convenient downloading into your computer system.
