This part of IEC 61076-2 describes the B12 bayonet coupling interface of circular connectors employing the mating interfaces described in IEC 61076-2-101:2012 and
IEC 61076-2-109:2014, that are typically used for industrial process measurement and control. These connectors consist of fixed and free connectors either rewirable or
non-rewirable, with bayonet-coupling. These connectors may have glass to metal seal inserts. They have male or female contacts and are deemed be intermateable with corresponding free connectors produced according to this document. Male connectors have round contacts
Ø 0,6 mm, Ø 0,76 mm, Ø 0,8 mm and Ø 1,0 mm.

Differing codings prevent the mating of these individually coded fixed connectors (and consequently of individually coded free connectors deemed to bayonet couple with them) to other interfaces and cross-mating between the different codings. However, the styles and interface dimensions, except for the coupling mechanism, are given in 4.3 of
IEC 61076-2- 101:2012 and 4.3.1 of IEC 61076-2-109:2014.

The male type B12 circular connectors are interoperable with the female type B12 connector of the same coding and ways. The female type B12 connectors are interoperable with the male type B12 and M12 (threaded screw coupling) connector of the same coding and ways.

NOTE – B12 relates to a bayonet coupling with tube dimensions compatible with a M12 thread. M12 is the dimension of the thread of the screw-coupling mechanism of circular connectors covered by IEC 61076-2-101:2012 and IEC 61076-2-109:2014, which provide the mating interface (connector insert level) to these connectors with bayonet coupling.

This clause of Part 1 is applicable, except as follows.

1.1.1 Equipment included in scope

Replacement:

This part of IEC 61010 specifies safety requirements and related verification tests for control equipment and/or their associated peripherals.

Some equipment examples are:

programmable logic controller (PLC);

programmable automation controller (PAC);

distributed control systems (DCS);

industrial PC (computers) and panel PC;

programming and debugging tools (PADTs);

displays and human-machine interfaces (HMI);

any product performing the function of control equipment and/or their associated peripherals;

positioners; and

control equipment which have as their intended use the command and control of machines, automated manufacturing and industrial processes, e.g. discrete and continuous control.

Components of the above named equipment and in the scope of this standard are e.g.:

(auxiliary) stand-alone power supplies;

peripherals such as digital and analogue I/O,

remote-I/O;

industrial network equipment, embedded or standalone (e.g. switches, routers, wireless base station).

Control equipment and their associated peripherals are intended to be used in an industrial environment and may be provided as open or enclosed equipment.

NOTE 1 Control equipment intended also for use in other environments or for other purposes (example: for use in building installations to control light or other electrical installations, or for use on cars, trains or ships) can have additional conformity requirements defined by the safety standard(s) for these applications. These requirements can involve as example: insulation, spacings and power restrictions.

NOTE 2 Computing devices and similar equipment within the scope of IEC 60950 (planned to be replaced by IEC 62368) and conforming to its requirements are considered to be suitable for use with control equipment within the scope of this standard. However, some of the requirements of IEC 60950 for resistance to moisture and liquids are less stringent than those in IEC 61010-1:2010, 5.4.4 second paragraph.

Control equipment covered in this standard is typically intended for use in overvoltage category II (IEC 60664-1) in low-voltage installations, where the rated equipment supply voltage does not exceed AC. 1 000 V r.m.s. (50/60 Hz), or DC 1 000 V.

Where control equipment is intended for installation to supply systems with overvoltage category III or IV, additional requirements are identified in Annex K.

The requirements of ISO/IEC Guide 51 and IEC Guide 104, as they relate to this part of
IEC 61010, are incorporated herein.

1.1.2 Equipment excluded from scope

Replacement:

This standard does not deal with aspects of the overall automated system, e.g. a complete assembly line. Control equipment (e.g. DCS and PLC), their application program and their associated peripherals are considered as components (components in this context are items which perform no useful function by themselves) of an overall automated system.

Since control equipment (e.g. DCS and PLC) are component devices, safety considerations for the overall automated system including installation and application are beyond the scope of this standard. Refer to IEC 60364 series of standards or applicable national/local regulations for electrical installation and guidelines.

1.2.1 Aspects included in scope

Replace first sentence:

The purpose of the requirements of this standard is to ensure that all hazards to the operator, service personnel and the surrounding area are reduced to a tolerable level.

NOTE By using the terms "operator" and "service personnel" this standard considers the perception of hazards depending on training and skills. Annex AA gives a general approach in this regard.

1.2.2 Aspects excluded from scope

Replacement:

This standard does not cover:

reliability, functionality, performance, or other properties of the control equipment not related to safety;

mechanical or climatic requirements for operation, transport or  storage;

EMC requirements (see e.g. IEC 61326 or IEC 61131-2);

protective measures for explosive atmospheres (see e.g. IEC 60079 series);

functional safety (see e.g. IEC 61508, IEC 61131-6).

The electrical continuity test is to verify that cable metallic elements are electrically continuous throughout the cable.  Electrical continuity is important for bonding and grounding, toning for location, and other related system issues, and may represent a “goodness of manufacture" criteria.  Typically, the test is one of continuity and carries no resistance or conductivity requirement.  The metallic elements may be tested individually or may be tested as a total group.  Since this latter criterion is frequently the case, all elements are to be measured as a group unless specified otherwise.

NOTE Detail specifications may allow such elements as strength members to be non-continuous throughout the cable. This is a special case, and attention is directed to the detail specification.

This part of IEC 62047 specifies a test method for measuring the adhesion strength of metal powder paste in the electrical interconnection between micro-electromechanical systems (MEMS) and a circuit board.  The typical examples of the metal powder paste are anisotropic conductive paste, solder paste, and nanoscale metallic inks. The pattern diameter of the metal powder paste ranges from 10 ㎛ and 500 ㎛. As the dimensions of MEMS decrease below 500 ㎛ and 3-dimensional assembly of MEMS is needed, the adhesion between the MEMS and metal powder paste plays a critical role in transferring the devices on the powder paste. In this test method, a uniaxial compression load is applied to a metal powder paste using a plano-convex shape glass lens simulating an actual device; then the adhesion strength is measured by retracting the lens. This test method is useful when the adhesion strength should be analyzed by considering the actual contact area between the device and metal powder particles.

When a requirement in this standard is different from IEC 60945 or other standards, the requirement in this standard takes precedence.

This standard incorporates the performance standards of IMO Resolution MSC.471(101), the International Telecommunication Union (ITU) Radio Regulations as well as the technical characteristics for such transmitters contained in Recommendation ITU-R M.633, and takes account of the general requirements contained in IMO Resolution A.694(17).

This standard also includes minimum performance standards for a non-float-free EPIRB without float-free release mechanism (see Annex C).

NOTE 1 Although a number of the requirements and tests may be similar this standard is not intended to be used with 406 MHz Ship Security Alert System (SSAS) Beacons.

All texts of this standard, whose wording is identical to that in the IMO Resolutions A.662(16), A.694(17), and MSC.471(101) will be printed in italics and the Resolution/Recommendation and paragraph number indicated between brackets.

NOTE 2 Classes of EPIRB's considered in this document are:


– Class 0: Category 1 Float-free (–55 °C to +70 °C). The float-free release mechanism (A.662(16)) should be capable of operating throughout the temperature range of –30 °C to +65 °C and of surviving a stowage temperature range of (–55 °C to +70 °C).

– Class 1: Category 1 Float-free (–40 °C to +55 °C). The float-free release mechanism (A.662(16)) should be capable of operating throughout the temperature range of –30 °C to +65 °C and of surviving a stowage temperature range of (–40 °C to +65 °C).

These classes are not required by IMO Resolutions but may be applied at the discretion of each Administration.

– Class 2: Category 1 Float-free (–20 °C to +55 °C). The float-free release mechanism (A.662(16)) should be capable of being stowed and of operating throughout the temperature range of –30 °C to +65 °C.

NOTE 3 Category 2 Non float-free, EPIRB's in all classes are considered in Annex C.

NOTE 4 All classes include a 121,5 MHz homing device, described in Annex D.

NOTE 5 All classes include an AIS Locating Signal, described in Annex E.

NOTE 6 All classes include beacon position data, obtained from a navigation device internal to the EPIRB and may also provide an external navigation input as described in Annex B.
