Thermal stability per MIL-STD-883J, Method 5011 (sect. 3.5.2 & 3.8.5), tested in accordance with ASTM D3850

MIL-STD-883J ApprovedThermogravitmetric Analysis (TGA) is an important tool used for material characterization across many different industries. Thermogravimetric Analysis (TGA) is simply the study of a material’s weight change as a function of temperature and time under a controlled atmosphere. It can be used to determine the thermal stability of a material.

MIL-STD-883J section 3.5.2 and 3.8.5 are subsections of the United States Military Standards set by the U.S. Department of Defense that refer to the thermal stability of a material. In this standard, a TGA test is run using suitable TGA equipment or in accordance with ASTM D3850.

Samples are placed in a Nitrogen atmosphere (20-30mL/min flow). They begin at room temperature (25°C) and then get heated 10°C/min up to a final temperature of 200°C. During this test, the weight of the samples is continuously measured.

A material passes this standard if the weight loss at 200°C is less than or equal to 1.0% of the cured material weight. Three samples are tested and the average value of the three must meet or exceed the minimum requirements.
