"QTM" or "PTM" Test Standards?

[tk90]

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.

For anyone that finds this query in the future, these tests were created by Mitsubishi Chemical Group. I have not been able to find the specific test specs as of yet.

QTM55007 is run on a Falex style machine similar to that of ASTM D3702.
QTM55010 is run on a custom machine.
