This International Standard specifies test methods and requirements for power cable systems, cables with extruded insulation and their accessories for fixed submarine installations, for rated voltages from 6 kV (Um = 7,2 kV) up to 60 kV (Um = 72,5 kV).

The standard includes the electrical tests and the physical tests on materials as well as the specific mechanical tests that are applicable to submarine cable systems.

The requirements apply to armoured single-core cables and three-core cables in combination with their accessories, terminations and joints for usual conditions of installation and operation, but not to special cables and their accessories, such as submarine cables for dynamic applications (i.e. for direct connection to a floating structure), for which modifications to the standard tests may be necessary or special test conditions may need to be devised.

This standard is applicable to submarine cables installed in permanently submerged conditions with water depths up to 250 metres.

Note: This standard does not include accessories having a mechanical function only, such as hang-offs or armour clamps.

The IEC 62386 series specifies a bus system for control by digital signals of electronic lighting equipment.

Typically, a bus unit according IEC 62386 contains firmware. There are circumstances where it might be necessary to change the firmware after production or shipping of the product. For example if the bus unit does not operate as intended. In such a case, a firmware update of a bus unit via the interface is beneficial.

This firmware update process is primarily designed to be a bug fix process not a feature extension process.

NOTE 1: Nevertheless the firmware update process may be used for feature extensions. But the risk of negative effects to the complete system should be considered in detail.

NOTE 2: Annex B provides a “Firmware Update Management Check Sheet” to support risk estimation.

This document for electromagnetic immunity requirements applies to lighting equipment which is within the scope of IEC technical committee 34, including apparatus such as lamps, luminaires, and modules.

Excluded from the scope of this document are:

components or modules intended to be built into lighting equipment and which are not end-user replaceable;

equipment for which the electromagnetic compatibility requirements in the radio-frequency range are explicitly formulated in other CISPR standards, even if they incorporate a built-in lighting function.

NOTE  Examples of exclusions are:

equipment with built-in lighting devices for display back lighting, scale illumination and signaling;

< >

range hoods, refrigerators, freezers;

photocopiers, projectors;

lighting equipment for road vehicles (in scope of CISPR 12)

lighting equipment for aircraft and airfield facilities

However, in multi-function equipment where the lighting function operates independently from other functions, the electromagnetic immunity requirements of this standard apply to the lighting function only.

Lighting equipment with a wireless control function are also within the scope of this document. However, the test is limited to the control of the lighting function only. Radio properties like frequency stability or spurious emissions are not assessed. For example, colour/light level control via a wireless interface should stay intact after an immunity test.

Also included in the scope of this document is lighting equipment that interfaces with systems or installations other than common power supply networks or communication networks.

EXAMPLES  Lighting equipment that is connected to home and building electronic systems (HBES) or building automation and control systems (BACS) is in the scope of this document.

The requirements of this standard are based on the requirements for domestic, commercial and light-industrial environments as given in IEC 61000-6-1:2016, but modified to lighting engineering practice.

It can be expected that lighting equipment complying with the requirements of this standard will operate satisfactorily in other environments. In some special cases, measures have to be taken to provide higher immunity. For this publication it is impracticable to deal with all these possibilities. Such requirements may be established by contractual agreement between supplier and purchaser.

This Clause of Part 1 is completely replaced by:

This Part of IEC 60669 applies to electronic control devices which is used as a general term to cover electronic switches, HBES/BACS switches and electronic extension units.

It applies to electronic switches and to HBES/BACS switches, for alternating current (AC) only with a rated switching voltage not exceeding 250 V and a rated current not exceeding 16 A, intended for household and similar fixed electrical installations, either indoors or outdoors.

It also applies to electronic extension units with a rated supply voltage not exceeding 250 V AC and 120 V DC, such as sensors and push buttons controlling the electronic switches, or the HBES/BACS switches or similar control devices used in lighting systems in the building environment.

NOTE 1 An example of lighting systems is DALI.

This Part of IEC 60669 also applies to electronic RCS and electronic TDS. Particular requirements are given in Annex FF.

Switches including only passive components such as resistors, capacitors, inductors, PTC and NTC components, varistors, printed wiring boards and connectors are not considered as electronic control devices.

This Part of IEC 60669 also applies to electronic switches and HBES/BACS switches for the operation of lighting equipment circuits and the control of the brightness of lighting equipment (dimmers) as well as the control of the speed of motors (for example, those used in ventilating fans) and for other purposes (for example, heating controls).

The operation and/or control as mentioned above may be transmitted by an electronic signal via several media, e.g. powerline (mains), twisted pair, optical fibre, radio frequency, infra-red, etc. and are performed:

intentionally by a person via an actuating member, a key, a card, etc., via a sensing surface or a sensing unit, by means of touch, proximity, turn, optical, acoustic, thermal;

by physical means, e.g. light, temperature, humidity, time, wind velocity, presence of people;

by any other influence.

This standard covers only those requirements for mounting boxes which are necessary for the tests on the electronic control devices.

Requirements for general purpose mounting boxes are given in IEC 60670.

This standard is not intended to cover devices falling within the scope of IEC 60730.

Electronic control devices complying with this standard are suitable for use at ambient temperature not normally exceeding 25 °C but occasionally reaching 35 °C with a lower limit of the ambient air temperature of –5 °C.

NOTE 2 For lower temperatures see ANNEX E.

Functional safety aspects are not covered by this standard. Functional safety requirements are covered by the standards of the controlled devices.

In locations where special conditions prevail, such as in ships, vehicles and the like and in hazardous locations, for example where explosions are liable to occur, special construction and/or additional requirements may be required.

NOTE 3 This standard is not intended to cover devices which are designed to be incorporated in appliances or are intended to be delivered together with a specific appliance and which are within the scope of IEC 60730 or
IEC 61058-1.

Examples of designs of electronic switches and functions are shown in annex AA.

NOTE 4 Electronic switches and HBES/BACS switches without a mechanical switch in the main circuit do not provide a “full off-state”. Therefore, the circuit on the load side should be considered to be live.
