ASTM D-709, 1997, “Standard Specifications for Laminated Thermosetting Materials.” This standard matches, fairly closely, the grades that are in NEMA LI-1 and was re-approved in 2001. For the most part, the reference to military standards is out of date, and most of them have been removed from circulation because they are obsolete.
This standard is utilized to obtain information about the test methodology used to measure specific properties. The ASTM is well recognized for its work in standardizing procedures and test methods as well as conditions that should be present in the laboratory or equipment from which the testing is performed. Norplex-Micarta’s lab and testing is done in strict accordance with the ASTM standards as described in this document.
