GB 9706.265-2021 Medical electrical equipment—Part 2-65:Particular requirements for the basic safety and essential performance of dental intra-oral X-ray equipment
Basic Information
Scope
This part of GB 9706 specifies the general requirements for the basic safety and basic performance of ME devices and ME systems.
This part applies to medical electrical equipment and medical electrical systems (hereinafter referred to as ME devices and ME systems).
If a chapter or clause explicitly states that it only applies to ME devices or ME systems, the title and the text of the chapter or clause will indicate this. If this is not the case, the relevant chapter or clause applies to both ME devices and ME systems.
Except for 7.2.13 and 8.4.1, the hazards (sources) caused by the intended physiological effects of ME devices or ME systems within the scope of this part are not specifically required in this part.
Replacement:
This part applies to the basic safety and basic performance of intraoral imaging dental X-ray machines and their main components, hereinafter referred to as ME devices.
The scope of this part is limited to X-ray machines containing high-voltage transformer assemblies in the X-ray tube assembly.
This part does not apply to extraoral imaging dental X-ray machines.
Note 1: The X-ray generators in intraoral imaging dental X-ray machines always contain an X-ray combination head. Therefore, in this part, the concept of X-ray tube assembly is replaced by X-ray combination head.
Note 2: For example, the main components may be an X-ray combination head and an electronic X-ray image receiver.
Note 3: Photostimulated phosphor plates and their readers (hardware and software) are not included in the scope of this part, as they do not use electrical components in the patient environment and are not ME devices.
ME devices and ME systems within the scope of GB 9706.263, GB 9706.244, IEC 60601-2-54, GB 9706.245, or GB 9706.243 are not included in the scope of this part. The scope of application of this part also does not include radiation therapy simulators and bone or tissue absorption density me
