REV 10 DIRECTION 2173227−100
1-4 Inspection
In order to assure continued performance of this x−ray equipment, a periodic inspection program must be established. It is the owner’s responsibility to supply or arrange for this service.
Periodic Maintenance can locate potential problems before they occur. Since maintenance checks involve cost, it is not practical to attempt to assure zero failures. The following inspection requirements, with suggested inspection intervals, are GE Healthcare recommendation for the most cost effective maintenance schedule.
Inspection intervals are based on average daily use of one eight hour shift. More frequent inspection is appropriate where equipment use is above average. Equipment that regularly exhibits out of tolerance conditions should also be inspected more frequently.
1-5 HHS Testing
The United States Department of Health and Human Services (HHS) has established performance requirements for diagnostic x−ray equipment. These requirements are defined in Title 21 of the Code of federal regulations (21 CFR), and apply only to certain specified components identified as “certified equipment.”
The manufacturer of specified diagnostic x−ray components must certify that the components:
1. Perform as required by the HHS standard when installed, adjusted, and tested as specified in the manufacturer ’s instructions to the assembler. Refer to Direction 2173222−100 AMX−4+ Installation for HHS compliance testing as it pertains to the AMX−4+ during installation.
2. Will continue to comply when maintained in accordance with the manufacturer’s instructions. The importance of HHS compliance testing cannot be over emphasized. Before starting Periodic Maintenance procedures, review Direction 46−013894 System Field Test for HHS. Pay particular attention to “Introduction” (Tab 1 of Direction 46−013894).
