721—22.15 (52) Application for reconsideration. Following denial of certification a vendor may make the necessary modifications to the system and apply for reconsideration. Aspects of the equipment which were approved in the initial application do not need to be reexamined unless the examiners find that the modifications may have affected the ability of the equipment to comply in other areas. If certification was denied for the reasons cited in 22.14(1) or 22.14(4), both test elections must be completed satisfactorily, or approval shall not be granted.
