This part of IEC 61223 applies to the performance of mammographic X-ray equipment when used in  mammographic tomosynthesis modes of operation, with respect to image quality and dose.

Excluded from the scope of this document are:

mammographic X-ray equipment modes of operation other than mammographic tomosynthesis;

2D images synthesized from the tomosynthesis images

reconstructive tomography other than mammographic tomosynthesis;

ct scanners covered by IEC 61223-3-5;

This part of IEC 61223 defines

the essential parameters which describe the acceptability criteria of mammographic tomosynthesis modes of operation of mammographic X-ray equipment with regard to image quality and dose; and

the methods of testing whether measured quantities related to those parameters comply with specified tolerances.

constancy test frequency when required

This part of IEC 61223 is intended to be applied along with the acceptability criteria included in IEC 61223-3-2 [1] or equivalent protocol for 2D mammography which are also relevant for mammographic tomosynthesis modes of operation.

These methods mainly rely on non-invasive measurements that use appropriate test equipment and are performed during or after the installation. Signed statements covering steps in the installation procedure can be used as part of the acceptance test. Tests required by a higher level of compliance take precedence over similar tests with a lower level of compliance.

When the results of the acceptance test are in compliance with the expected values, the baseline values for the subsequent constancy tests are established.

This Part 5 of the IEC 62828 standard series establishes specific procedures for testing flow transmitters used in measuring and control systems for industrial process and for machinery control systems. For general test procedures, reference is to be made to Part 1 of the standard, applicable to all types of transmitters.

The IEC 62828 Part 5 – together with Part 1 – is the reference standard for testing every type of flow transmitters, including not only for liquids but also for gases and for steam.

This standard “industrial flow transmitters” consistently covers all types of flow transmitters used in measuring and control systems for industrial process and for machinery.

Part 4 of the IEC 62828 standard series establishes specific procedures for testing level transmitters used in measuring and control systems for industrial process and machinery control systems. For general test procedures, reference is to be made to IEC 62828-1:2017 of the standard, applicable to all types of transmitters. Throughout this standard the term “industrial transmitters” covers all types of transmitters used in measuring and control systems for industrial processes and for machinery.

The requirements of this standard are applicable to all level measurement principles.

Detailed description of transmitters is given for two main principles for improved clarity.

This part of IEC 62714 specifies the integration of logic information as part of an AML model for the data exchange in a heterogenous engineering tool landscape of production systems.

This part of IEC 62714 specifies three types of logic information: sequencing, behaviour, and interlocking information.

This part of IEC 62714 deals with the six following sequencing and behaviour logic models (covering the different phases of the engineering process of production systems) and how they are integrated in AML: Gantt chart, activity-on-node network, timing diagram, Sequential Function Chart (SFC), Function Block Diagram (FBD), and mathematical expression.

This part of IEC 62714 specifies how to model Gantt chart, activity-on-node network, and timing diagram and how they are stored in Intermediate Modelling Layer (IML).

NOTE 1  With this, it is possible to transform one logic model into another one. A forward transformation supports the information enrichment process and reduces or avoids a re-entry of information between the exchanging engineering tools.

NOTE 2  Mapping of other logic models, e.g. event-driven logic models like state charts, onto IML is possible.

This part of IEC 62714 specifies how interlocking information is modelled (as interlocking source and target groups) in AML. The interlocking logic model is stored in Function Block Diagram (FBD).

This part of IEC 62714 specifies the AML logic XML schema that stores the logic models by using IEC 61131-10.

This part of IEC 62714 specifies how to reference PLC programs stored in PLCopen XML documents.

This part of IEC 62714 does not define details of the data exchange procedure or implementation requirements for the import/export tools.
