Hello, I was wondering if anyone had more information regarding "QTM" or "PTM" standards- they pertain to polymer testing (as seen https://www.boedeker.com/Technical-Resources/Technical-Library/ASTM-Property-Testing-Overview, for example).
They are likely some company's internal standards, but I would love to be proven wrong.
