Thermal stability per MIL-STD-883J, Method 5011 (sect. 3.5.2 & 3.8.5), tested in accordance with ASTM D3850
Thermogravitmetric 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.
The following products were tested by an independent lab and passed ASTM D3850:
