(b) Classification. Class II (special controls). A propoxyphene test system is not exempt if it is intended for any use other than employment or insurance testing. The device is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 862.9, provided the test system is intended for employment and insurance testing and includes a statement in the labeling that the device is intended solely for use in employment and insurance testing.
