BIS ISI Certification for Diagnostic Medical X-Ray Equipment

Diagnostic Medical X-ray equipment is primarily used to take pictures of areas inside the body. It focuses a small amount of radiation on the particular area of the body to examine. The x-rays pass through the body & create a picture on a computer display or on a thin film. All the Manufacturers of Diagnostic Medical X-ray equipment in India are required to comply with the Mandatory Product Certification under IS 7620 (Part-1) as per BIS. All the Manufacturers or Importers of Diagnostic Medical X-ray equipment are applicable to sell their products in the Indian Market only after obtaining BIS ISI Certification for Diagnostic Medical X-ray equipment issued by the Bureau of Indian Standards (BIS). ISI Mark[1] on the product ensures the product’s quality along with the consumer’s safety. So, the manufacturers of x-ray equipment must have the BIS ISI Certification for Diagnostic Medical X-ray equipment after proper testing under BIS.

Growth of the Medical Care Sector in India

The Medical Care Sector is trusted to observe development in future, inferable from the headways in innovation (the discovery Diagnostic Medical X-ray equipment has advanced to turn out to be more strong, protected & simple to use). Moreover, in a non-industrial country like India, expanding earnings, simpler admittance to top-class medical care offices and more prominent familiarity with individual well-being & cleanliness are the components supporting the development of the Medical Services Industry.

Also, the more important infiltration of Health Care coverage supported the ascent in medical care consumption. Alongside that, with the expanding interest in reasonable & quality medical services, the entrance of health care coverage is ready to fill intensely later on. The expanding medical services costs & weight of new infections, combined with low Government financing, are helping to increase the interest in healthcare coverage inclusion.

The Indian Government intends to expand public medical care use by 2.5% of India’s GDP by 2025 and this move would support the other rising economies to build their uses.

General Requirements for BIS ISI Certification for Diagnostic Medical X-ray Equipment

The following are the general requirements for BIS ISI Certification for Diagnostic Medical X-ray Equipment:

  • Mechanical & Physical Requirements:
    • X-ray equipment shall be so formed & assembled that it shall have the rigidity & strength to resist the abuses to which it is liable to be subjected without increasing its fire hazard due to total or partial collapse with a resulting reduction of loosening, spacing, or displacement of parts/other series defects.
    • Sheet metal employed as an enclosure for x-ray equipment should be such thickness or shall be so formed/reinforced that its strength & rigidity should not be less than that of a flat steel sheet having an average thickness of 0.6mm.
    • The equipment’s electrical parts shall be so located/enclosed that suitable protection against accidental contact with uninsulated live-metal parts shall be provided.
    • Equipment parts which move shall be arranged/protected against contact in such a manner that the operator is endangered.
    • Equipment which is in use is placed on a table or on the floor and, when overturned, may present a hazard for the user or surroundings, shall have adequate stability.
    • Equipment should be manufactured in a manner that its electrical insulation may not be affected badly by water condensing on cold surfaces or by water leaking from hoses, couplings, and receptacles.
    • Protective sleaving shall only be used as supplementary insulation on insulated wires and shall be held in position by suitable means.
    • Cords, fuses, receptacles, attachment plugs, lamp holders, circuit breakers, motor-operated components, etc., which are provided as parts of X-ray equipment, shall be chosen regarding their suitability for the specific application & shall conform to appropriate Indian Standards (IS). In case an Indian Standard is not available, then it will be as agreed to between the purchaser & the manufacturer.
    • High-voltage equipment containing oil shall not be installed in a wooden cabinet.
    • All high-voltage equipment parts, including the X-Ray tube, shall be enclosed within a metallic enclosure provided with a means for earthing, if within an enclosure of suitable insulating material.
    • It shall not be possible to remove parts which make sure the requisite degree of protection against moisture without the help of tools.
    • It shall not be possible to fix in a wrong position actuating parts which show the setting of switching or setting devices, the incorrect of which may be the cause of danger to the patient or user (for example, circuit breakers, power controls, or main switches) as well as actuating parts which have to be removed in use.
    • The equipment shall have a device by means of which it may be separated on all poles from the mains.
    • Protective casings and protection devices shall have enough mechanical strength. They shall not be removable without the aid of a tool unless their removal is vital for proper use. Thermal cut-outs with automatic resetting & overload protection devices shall not be used; they may cause danger by unintentionally switching on again.
  • Radiation Protection: The X-ray equipment shall conform to all the relevant requirements prescribed under IS: 7061 for the protection of patients & personnel against ionising radiation.
  • Temperature Rise: Materials employed in the construction of X-ray equipment shall not be affected badly by the temperature attained under any condition of normal operation & also under the condition of normal idling (12 hrs). The temperature rise of different parts & materials shall not exceed the prescribed values.
  • Earthing:
    • X-ray equipment shall have provision for earthing of all exposed metal parts.
    • All parts of earthing conductor & terminal shall be corrosion-proof.
    • The connection between the earthing conductor terminals/earthing contact & the parts to be connected to the earth conductor shall be of low resistance.
  • Live Metal Parts:
    • No part of the frame or enclosure of x-ray equipment shall be used as a current-carrying part except for the self-contained tube head, which is earthed.
    • Friction between surfaces shall not be acceptable as a means to prevent the turning of live-metal parts, but an appropriate lock washer properly applied may be acceptable for this purpose.
    • Uninsulated live-metal parts shall be so secured to the base/mounting surface that they will be prevented from shifting/turning in position if such motion may result in a reduction of spacing below the minimum required.
  • Wiring and its Terminals: The wiring connection between parts of X-ray equipment shall be protected/enclosed, except that a suitable length of flexible cord or cable may be employed for external wiring or for interconnection between various components of the equipment of flexibility is vital.
