Part B: Supplementary Information Sheet (SIS)
FR Recognition List Number 053 Date of Entry 12/23/2019 
FR Recognition Number 12-328
Standard
IEC 61223-3-5 Edition 2.0 2019-09
Evaluation and routine testing in medical imaging departments - Part 3-5: Acceptance tests - Imaging performance of computed tomography X-ray equipment [Including: Technical Corrigendum 1 (2006)]
Scope/Abstract
This part of IEC 61223 applies to CT SCANNERS that conform to IEC 60601-2-44:2009, IEC 60601-2-44:2009/AMD1:2012 and IEC 60601-2-44:2009/AMD2:2016.
IEC 60601-2-44 and this document
. defines the essential parameters which describe the performance of CT SCANNERS with regard to image quality, RADIATION OUTPUT and PATIENT positioning; the list of parameters to be tested can be found in 4.3,
. defines the methods of testing the essential parameters, and
. evaluates compliance with the tolerances of the parameters SPECIFIED by the ACCOMPANYING DOCUMENTS.

The methods defined in IEC 60601-2-44 and this document rely on non-invasive measurements, using appropriate test equipment, performed during or after installation. Signed statements covering steps in the installation procedure can be used as part of the ACCEPTANCE TEST report.

This document applies to ACCEPTANCE TESTS and CONSTANCY TESTS on a CT SCANNER. The aim of the ACCEPTANCE TESTS is to verify compliance of the installation or MAJOR SERVICE ACTION with specifications affecting the image quality, RADIATION OUTPUT and PATIENT positioning. The CONSTANCY TESTS are performed to ensure that the functional performance of EQUIPMENT meets ESTABLISHED CRITERIA and to enable the early recognition of changes in the properties of components of the EQUIPMENT, and to verify compliance with specifications affecting the image quality, RADIATION OUTPUT and PATIENT positioning.

This document also contains requirements associated with ACCEPTANCE TEST and CONSTANCY TEST for the ACCOMPANYING DOCUMENTS of the CT SCANNER.

This document does not apply to
. aspects of mechanical and electrical safety, and
. aspects of mechanical, electrical and software performance, unless they are essential for performing the ACCEPTANCE TESTS and CONSTANCY TESTS, and are directly affecting image quality, RADIATION OUTPUT and PATIENT positioning.
Extent of Recognition
Complete standard
Rationale for Recognition
This standard is relevant to medical devices and is recognized on its scientific and technical merit and/or because it supports existing regulatory policies.
Transition Period
FDA recognition of IEC 61223-3-5 First edition 2004-08[Including: Technical Corrigendum 1 (2006)] [Rec# 12-270] will be superseded by recognition of IEC 61223-3-5 Edition 2.0 2019-09 [Rec# 12-328]. FDA will accept declarations of conformity, in support of premarket submissions, to [Rec # 12-270] until December25, 2022. After this transition period, declarations of conformity to [Rec # 12-270] will not be accepted.
