Is the temperature called out in IPC-TM-650 2.6.8 specific to FR-4?

Is this test valid for Composite material such as MC-3D material from
Glassteel Industrial Laminates?

What is the reason for specifying 550°C temperature?

What kind of acceleration factors or failure rates can been expected from
this test?

If test is run at 475°C to 500°C and boards pass test what kind of life
expectancy can be expected Vs testing at 550°C?

Is this test designed to be a destructive test for composite materials?
