This document defines terminology, structure, and a characteristic test method of an optical current sensor using the polarimetric method. It addresses the current sensing element only and not the additional devices that are unique to each application (see 3.11). Generic specifications for fibre optic sensors are defined in IEC 61757.

As the specifications of optical polarimetric fibre current sensors required by each user vary depending on the application, this document does not define the required performance values. The required performance values are defined when designing a sensor according to the specific application.

Photovoltaic (PV) modules are electrical devices normally intended for continuous outdoor exposure during their lifetime. Highly corrosive wet atmospheres, such as marine environments or locations near the ocean or other large bodies of salt water, could eventually degrade some of the PV module components (corrosion of metallic parts, deterioration of the properties of some non-metallic materials - such as protective coatings and plastics - by assimilation of salts, etc.) causing permanent degradation that could impair their functioning. Temporary corrosive atmospheres are also present in places where salt is used in winter periods to melt ice formations on streets and roads.

This Standard describes test sequences useful to determine the resistance of different PV modules to corrosion from salt mist containing Cl- (NaCl, MgCl2, etc.). All tests included in the sequences are fully described in IEC 61215-2, IEC 62108, IEC 61730-2 and IEC 60068-2-52. The bypass diode functionality test in this Standard is modified from its description in 61215-2. They are combined in this Standard to provide means to evaluate possible faults caused in PV modules when operating under wet atmospheres having high concentration of dissolved salt (NaCl). Depending on the specific nature of the surrounding atmosphere to which the module is exposed in real operation several testing methods can be applied, as defined in IEC 60068-2-52. Guidance for determining the applicability of this standard and selecting an appropriate method is provided in Annex A.

This Standard can be applied to both flat plate PV modules and concentrator PV modules and assemblies.

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 document provides requirements and specific guidance for the safe operation and maintenance of optical fibre communication systems (OFCSs). In these systems optical power is possibly be accessible outside the confines of the transmitting equipment and/or at great distance from the optical source.

This document requires the assessment of hazard level at each accessible location of the OFCS as a replacement for product classification according to IEC 60825-1. It applies to the installed OFCS as an engineered, end-to-end assembly for the generation, transfer and receipt of optical radiation arising from lasers, light-emitting diodes (LEDs) or optical amplifiers, in which the transference is by means of optical fibre for communication and/or control purposes.

Individual components and subassemblies that fall under the definition of a laser product are subject to the applicable subclause(s) of IEC 60825-1. This document is applicable to individual components and subassemblies intended to be installed within OFCSs.

This document does not apply to optical fibre systems primarily designed to transmit optical power for applications such as material processing or medical treatment.

Throughout this document, a reference to ‘laser’ is taken to include LEDs and optical amplifiers.

In addition to the hazards resulting from laser radiation, OFCSs possibly give rise to other hazards, such as fire.

This document does not address safety issues associated with explosion or fire with respect to OFCSs deployed in explosive atmospheres.

NOTE The hazard presented by optical radiation emerging from a fibre is determined by the wavelength and power emerging from the fibre and also by the optical characteristics of the fibre itself (see Annex A).

The objective of this document is to:

–   protect people from optical radiation emitted by OFCSs;

–   provide requirements for manufacturers, installation organisations, service organisations and operating organisations in order to establish procedures and supply information so that proper precautions can be adopted;

–   ensure adequate warnings are provided to individuals regarding the potential hazards associated with OFCSs through the use of signs, labels and instructions.

Annex A gives a more detailed rationale for this document.

The safety of an OFCS depends to a significant degree on the characteristics of the equipment forming that system. Depending on the characteristics of the equipment, it is necessary to mark relevant safety information on the product or include it within the instructions for use.

Where required by the level of potential hazard, this document places the responsibility for the safe deployment and use of these systems on the installer or end-user / operating organisation or both. This document places the responsibility for adherence to safety instructions during installation and service operations on the installation organisation and service organisation as appropriate, and operation and maintenance functions on the end-user or operating organisation. It is recognised that the user of this document may possibly fall into one or more of the aforementioned categories of manufacturer, installation organisation, end-user or operating organisation.

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.

This part of IEC 60747 specifies the measuring method of the internal quantum efficiency (IQE) of single light emitting diode (LED) chip or package without phosphor. White LEDs for lighting applications are out of the scope of this part of IEC 60747. This part utilizes only the relative external quantum efficiency (EQE) measured at an operating room temperature. In order to identify the reference IQE, an operating current corresponding to the injection efficiency of 100 % is found and the radiative efficiency is determined by the infinitesimal change of the relative EQE at that point. The IQE as a function of current is then calculated from the relative ratio of the EQEs to the value at the reference point, which is called room-temperature reference-point method (RTRM).

White LEDs for lighting applications are out of the scope of this part of IEC 60747. This part utilizes the relative external quantum efficiencies (EQEs) measured at cryogenic temperatures and at an operating temperature, which is called temperature-dependent electroluminescence (TDEL). In order to identify the reference IQE of 100 %, the maximum values of the peak EQE are found by varying the environmental temperature and current.
