While the previously existing standards for s

41、uch equipment were dedicated to components and subsystems, this particular standard addresses the system level of DENTAL INTRA-ORAL X-RAY EQUIPMENT. Components and their functions are addressed as far as necessary. The minimum safety requirements specified in this particular standard are considered

42、to provide for a practical degree of safety in the operation of DENTAL INTRA-ORAL X-RAY EQUIPMENT. The minimum safety requirements for DENTAL EXTRA-ORAL X-RAY EQUIPMENT are specified in a separate particular standard IEC 60601-2-63 to simplify and improve the readability This particular standard ame

43、nds and supplements IEC 60601-1 (third edition, 2005): Medical electrical equipment Part 1: General requirements for safety and essential performance, hereinafter referred to as the general standard. Within its specific scope, the clauses of this particular standard supersede and replace those of IE

44、C 60601-2-7, Medical electrical equipment Particular requirements for the safety of high-voltage generators of diagnostic X-ray generators. Requirements particular to DENTAL X-RAY-EQUIPMENT which were included in previous editions of the collateral standard IEC 60601-1-3 or the particular standard I

45、EC 60601-2-28, IEC 60601-2-7 or IEC 60601-2-32 have been extracted and moved into this particular standard. All requirements addressing integrated X-RAY TUBE ASSEMBLIES are covered by this particular standard. Therefore IEC 60601-2-28 does not apply to equipment in the scope of this International St

47、s: 201.1.1 Scope Replacement: This International Standard applies to the BASIC SAFETY and ESSENTIAL PERFORMANCE of DENTAL INTRA-ORAL X-RAY EQUIPMENT and its main components, hereafter also called ME EQUIPMENT. The scope of this standard is restricted to X-RAY EQUIPMENT where the X-RAY TUBE ASSEMBLY

48、contains the HIGH-VOLTAGE TRANSFORMER ASSEMBLY. DENTAL EXTRA-ORAL X-RAY EQUIPMENT is excluded from the scope of this standard NOTE 1 The X-RAY GENERATOR in DENTAL INTRA-ORAL X-RAY EQUIPMENT always comprises an X-RAY MONOBLOCK ASSEMBLY. Therefore in this particular standard the concept of X-RAY TUBE

49、ASSEMBLY is replaced by that of X-RAY MONOBLOCK ASSEMBLY. NOTE 2 Main components may be for instance the X-RAY MONOBLOCK ASSEMBLY and an ELECTRONIC X-RAY IMAGE RECEPTOR. NOTE 3 Photostimulated phosphor plates and their readers (hardware and software) are excluded from the scope of this particular standard, since they have no electrical APPLIED PARTS in the PATIENT ENVIRONMENT, and are not ME EQUIPMENT. ME EQUIPMENT and ME SYSTEMS in the scope of IEC 60601-2-63, IEC 60601-2-44, IEC 60601-2-54, IEC 60601-2-45 or IEC 60
