This test procedure is for qualification testing of powered gas/brake control systems to assure compliance with the Recommended Practices for these assistive devices. A powered gas/brake control system which passes all of the tests shall be considered to be in compliance with the Recommended Practices. The control shall pass all tests denoted by a "shall" in the Recommended Practice or the Recommended Test Procedure. All the results of all tests and requirements denoted by a "should" shall be noted, but failure to comply will not constitute failure to pass the test. Testing Protocol: Two production samples of the powered gas/brake control system and a documentation package shall be submitted to the testing facility designated to perform the testing. The test facility will be designated by the manufacturer. Installed System: A complete installed system shall be available for continuous use during the course of testing. The vehicle shall have the complete installation of the powered gas/brake control system as it would be delivered to the user including all labeling and manuals. Uninstalled System: A complete uninstalled system shall be supplied for bench testing and study of individual components. All parts of the original equipment system which are modified in any way, and all additional parts that make up the powered gas/brake control system installation (labels, gauges, hoses etc.) shall be supplied.
