[Code of Federal Regulations] [Title 21, Volume 8] [Revised as of April 1, 2002] From the U.S. Government Printing Office via GPO Access [CITE: 21CFR892.1] [Page 504] TITLE 21--FOOD AND DRUGS CHAPTER I--FOOD AND DRUG ADMINISTRATION, DEPARTMENT OF HEALTH AND HUMAN SERVICES (CONTINUED) PART 892--RADIOLOGY DEVICES--Table of Contents Subpart A--General Provisions Sec. 892.1 Scope. (a) This part sets forth the classification of radiology devices intended for human use that are in commercial distribution. (b) The identification of a device in a regulation in this part is not a precise description of every device that is, or will be, subject to the regulation. A manufacturer who submits a premarket notification submission for a device under part 807 cannot show merely that the device is accurately described by the section title and identification provision of a regulation in this part but shall state why the device is substantially equivalent to other devices, as required by Sec. 807.87. (c) To avoid duplicative listings, a radiology device that has two or more types of uses (e.g., use both as a diagnostic device and a therapeutic device) is listed in one subpart only. (d) References in this part to regulatory sections of the Code of Federal Regulations are to chapter I of this title 21, unless otherwise noted.
