#### 8. Product Performance Testing

All testing that is required by the required standards has been performed. Non-clinical testing was performed and included standards such as ISO 5361 and ISO 10993-1. The Endobronchial Tube have been found to fall within the required limits of the testing. The test results can be found in both the Biocompatibility (Section16) and the Performance Testing_Bench (Section19) of this submission. Therefore we have concluded that the Endobronchial Tube are substantially equivalent.

A brief summary of tests relied upon to demonstrate substantial equivalence to the predicate can be found in the table below:
