The name and address of the testing lab that did each test.
The date of each test.
For manufacturers, the date each test report was received from a lab. For labs, the date each test report was sent to a manufacturer.
For extruded polystyrene, polyurethane, and polyisocyanurate, the age (in days) of the specimen that was tested.
For aluminum foil, the emissivity level that was found in the test.
