3 Terms and definitions

In this standard, the following terms are used with the corresponding definitions:

1 The alphabetical index of terms in Russian is given at the end of this standard.

2 Unless otherwise indicated by the terms. "voltage" and "current" imply their rms values.

1 Operating voltage takes into account resonant voltages.

2 When determining the operating voltage, the effect of transient voltages is not taken into account.

Note – If the power consumption is not indicated for the device, then the rated power consumption for heating and combination devices is the power measured during normal operation of the device with the power supply with the rated voltage.

Note – If the current for the device is not specified, then the rated current is considered:

– for heaters, the current calculated from the rated power consumption and rated voltage;

– electromechanical and combined devices – the current measured during normal operation of the device when supplied with rated voltage.

NOTE A control device with infrared radiation is not in itself considered as a remote operation mode control. However, it may be an integral part of such systems as a telecommunications system, sound control system or bus information transfer system.

Note – In devices powered by batteries, if the battery is housed in a separate case, the flexible wire or cord connecting this case to the device is treated as an interconnect cable.

Note – A power cord may be specially prepared and supplied only by the manufacturer or its service representative. Specially prepared cord may include part of the device.

Note – This does not mean that the insulation should be uniform. It may consist of several layers that cannot be tested separately as additional or basic insulation.

NOTE Class 0 appliances have either an insulating material enclosure, which is the main insulation or part of it, or a metal enclosure that is separated from current-carrying parts with appropriate insulation. A device with an insulating material housing that has a device for earthing internal parts is considered a device of classes I or 0I.

NOTE These safety measures include a protective earth conductor in the power cord.

1 Such devices belong to one of the following types:

– a device that has a solid and almost continuous body made of insulating material, inside which all metal parts are enclosed, with the exception of small parts, such as a marking plate, screws and rivets, which are separated from the current-carrying parts with insulation equivalent to at least reinforced insulation; such a device is called a class II device in an insulating housing;

– a device that has an almost solid metal case, in which double or reinforced insulation is used everywhere; such a device is called a class II device in a metal case;

– a device that is a combination of a class II device in an insulating case and a class II device in a metal case.

2 The case of a class II device in an insulating case may be additional or reinforced insulation or part of it.

NOTE In addition to supplying safe extra-low voltage, basic insulation may be required (see

1 In addition to supplying safe extra-low voltage, basic insulation may be required (see

2 If the main part of the device is powered by a safe extra-low voltage and comes with a removable power supply, then this main part of the device is considered a class III design in a class I device or a class II device, respectively.

If the safety extra-low voltage is obtained from the mains, it must be supplied through a safety isolating transformer or converter with separate windings, the insulation of which meets the requirements for double or reinforced insulation.

1 The established voltage limits are based on the assumption that the safety isolation transformer is supplied with a nominal voltage.

2 Safety extra-low voltage is also referred to as BSNN.

1 Protective shielding is the separation of circuits from live parts with a grounded shield.

2 The extra-low voltage protective circuit is also referred to as an OCHN circuit.

Note – Magnetic driven instruments are considered electromechanical instruments.

1 If some part needs to be removed when installing the device, this part is not considered removable, even if the instruction states that it should be removed.

2 Components that can be removed without a tool are considered removable parts.

NOTE Available non-metallic parts with a conductive coating are considered accessible metal parts.

1 Parts available or unavailable corresponding

2 PEN-conductor is a neutral conductor with protective earthing, combining the functions of both protective and neutral conductor.

Note – The part that is too small to hold, but at the same time to which the glowing wire test can be applied, is shown in example A of Figure 5. The part that is large enough to hold, but that is too small to apply the hot glow test , shown in example B of figure 5. Example C of figure 5 shows a part that is not a small part.

Note – The thermal limiter does not work in the opposite direction during the normal operating cycle of the device. It may or may not be required to manually reset.

NOTE Manual exposure involves turning off the instrument from the power supply.

Note – Such a part can be a replaceable component, such as a resistor or capacitor, or a part of the component to be replaced, such as a replaceable unavailable thermo-link embedded in the motor.

Note – In multiphase instruments, the neutral conductor is not considered a power conductor.

Note – Position "turned off" does not mean turning off all poles.

Note – Neon indicators are not considered electronic components.

NOTE Parts of this circuit can also be used for functional purposes.

4 General requirements

The devices must be designed in such a way that during normal operation they work safely and do not cause harm to people or the environment even in the case of careless handling possible during normal operation.

Basically, this principle is achieved by fulfilling the relevant requirements contained in this standard, and compliance is checked by carrying out appropriate tests.

5 General test conditions

Unless otherwise indicated, tests are conducted in accordance with this section.

Note – Acceptance tests are described in Appendix A.

1 Additional samples may be required if the device should be tested under different conditions, for example, if it is designed for different supply voltages.

If the intentionally weakened part opens the circuit during the tests of clause 19, an additional sample may be required.

Component tests may require additional samples of these components.

If tests on Annex C are carried out, six engine samples are required.

If tests on Annex D are carried out, an additional instrument sample may be used.

If tests are carried out on Annex G, four additional transformers are required.

If tests are carried out on Annex H, three switches or three additional devices are required.

2 Accumulation of overloads should be avoided with positive sequential testing of electronic circuits. It may be necessary to replace components or use additional samples. The number of additional samples should be reduced to the minimum number by the method of analyzing the corresponding electronic circuits.

3 If the instrument is to be disassembled for testing, after assembly it is necessary to ensure that it is assembled in the same way as during the initial delivery. In case of doubt, further testing can be carried out on a separate sample.

If it is clear from the device design that a specific test is not applicable, then this test is not carried out.

1 If the means for adjusting the control device is accessible without a tool, then this clause applies regardless of whether the adjustment can be changed manually or with a tool. If the means of adjustment are not available without the aid of a tool or if the consumer does not intend to change their position, then this clause is not used.

2 Sealing is considered as a way to prevent a change in the position of consumer controls.

Unless otherwise specified, for instruments with a supply voltage selection switch, the tests are performed at the switch position corresponding to the nominal voltage.

If the temperature of any part is limited by a temperature-sensitive device or it is influenced by the temperature at which a change of state occurs, for example, water boiling, then in case of doubt the ambient temperature is maintained within (23 ± 2) ° C.

Devices designed to operate on alternating current, the marking of which does not indicate the nominal frequency or the range of nominal frequencies from 50 to 60 Hz, are tested at a frequency of 50 or 60 Hz, whichever is the most unfavorable.

If for electromechanical and combined instruments, marked with a range of nominal voltages, it is indicated that the tests are carried out at nominal voltage multiplied by a factor, then the magnitude of this voltage should be equal to:

– the upper limit of the range of nominal voltages multiplied by the coefficient, if the latter is greater than 1.0;

– the lower limit of the range of nominal voltages multiplied by the coefficient, if the latter is less than 1.0.

If the coefficient is not specified, the devices are tested at the most unfavorable supply voltage within the rated voltage range.

1 If the heater is rated for a rated voltage range, the upper limit will usually be the most unfavorable voltage within the range.

2 For electromechanical, combined devices and for devices rated for several nominal voltages or for several ranges of nominal voltages, it may be necessary to conduct several tests at minimum, average and maximum values ​​of nominal voltage or range of nominal voltages to determine the most unfavorable voltage.

– with the upper limit of the range of nominal power consumption, multiplied by the coefficient, if the latter is greater than 1.0;

– the lower limit of the nominal power consumption range multiplied by the coefficient, if the latter is less than 1.0.

If the coefficient is not specified, the most unfavorable power consumption is applied within the nominal power consumption range.

– when the value of power calculated by the upper limit of the range of nominal voltages multiplied by the coefficient, if the latter is greater than 1.0;

– when the value of power, calculated by the lower limit of the range of nominal voltages, multiplied by the coefficient, if the latter is less than 1.0.

If the coefficient is not specified, the power should correspond to the power consumption at the most unfavorable voltage within the rated voltage range.

The built-in and fixed devices before the start of the test are installed in accordance with the instructions attached to the devices.

For heating elements with a significant positive temperature coefficient of resistance, in addition to the PTC of the heating elements, the supply voltage is determined by first applying the nominal voltage to the device before the heating element reaches its operating temperature. Then the supply voltage is quickly increased to the value required to obtain the power consumption required by the appropriate test, and this value of the supply voltage is maintained throughout the test.

Note – In general, the temperature coefficient is considered significant if at nominal voltage the power consumption of the device in a cold state differs by more than 25% from the power consumption at the operating temperature.

Hair shielding at home

If the value of power consumption is indicated above the value of the nominal power consumption, then the coefficient for voltage is equal to the square root of the coefficient for power consumption.

If devices of classes 0I or I have non-metal parts that are available, these parts are checked for compliance with the requirements specified for class II construction, unless these parts are separated from the live parts by an intermediate grounded metal part.

Note – Appendix P provides guidance on expanding requirements that can be used to provide a sufficient level of protection against electrical and thermal hazards for particular types of devices used in installations without a protective ground wire in countries with a warm humid uniform climate.

Devices that are powered by batteries, use batteries that are not rechargeable or rechargeable in the device are tested according to Appendix S.

1 The first digit of the IP code is not required to be marked on the device.

2 Additional marking is allowed provided that it does not lead to misunderstanding.

3 If the instrument components are labeled separately, the instrument and component markings must be such as to not cause doubts about the marking of the instrument itself.

4 If an instrument is marked with a nominal pressure, the unit of measure may be a bar, but only with the value in Pascals. The pressure value in bars must be in brackets.

Devices of classes II and III with functional grounding shall be marked with the symbol IEC 60417-5018 (2011-07).

The housings of motorized water valves embedded in the external hoses connecting the appliance to the water supply system should be marked with the symbol IEC 60417-5036 (2002-10) if their operating voltage exceeds the ultra-low voltage.

8 Protection against access to live parts

Compliance is checked by inspection and testing

Lamps placed behind a removable cover are not removed if the device can be isolated from the mains using a plug or switch with all poles disconnected. However, protection against access to live parts of the lamp sockets placed behind removable covers should be provided when installing or removing lamps.

The test is carried out using test probe B according to IEC 61032 with application of force up to 1 N; the device is installed in all possible positions, except that devices normally used on the floor and having a mass of more than 40 kg are not tilted. The test probe is inserted through the holes to a depth that the probe allows, and the probe is rotated or bent to any possible position before, during and after its insertion. If the probe does not enter the hole, then the force acting on the probe in the forward direction is increased to 20 N. If, under the force of the probe, the probe enters the hole, then the test is repeated with the probe in a bent position.

It should not be possible for the test probe to come into contact with live parts or live parts protected only with varnish, enamel, plain paper, cotton cloth, oxide film, insulating beads or casting compound, with the exception of self-hardening resins.

Note – Instrument inputs are not considered sockets.

The test probe is also inserted through holes in earthed metal shells that have a non-conductive coating, such as enamel or varnish.

The possibility of touching the current-carrying parts with a test probe is not allowed.

The possibility of touching these live parts is not allowed.

Note – If the devices are equipped with a power cord and do not have switching devices in the power circuit, then disconnecting the plug from the outlet is considered to be one disconnecting action.

– the part is powered by safe extra low voltage provided that:

for AC, the peak voltage value does not exceed 42.4 V;

for DC, the voltage does not exceed 42.4 V;

– the part is separated from the live parts by protective impedance.

With protective impedance, the current between this part and the power supply should not exceed 2 mA for direct current, and for alternating current, the peak value should not exceed 0.7 mA, and in addition:

– for voltages with a peak value above 42.4 to 450 V inclusive, the capacitance shall not exceed 0.1 µF;

– for voltages with a peak value above 450 to 15 kV inclusive, the discharge should not exceed 45 µC;

– for voltages with a peak value above 15 kV, the discharge energy should not exceed 350 mJ.

Compliance is checked by measuring when the device is operated at rated voltage.

Voltages and currents are measured between the respective part and each pole of the power supply. The discharge is measured immediately after the power is cut off. Discharge and discharge energy is measured using a non-inductive resistor with a nominal resistance of 2000 ohms.

1 Circuit diagram for current measurement is given in IEC 60990 (Figure 4).

2 The magnitude of the discharge is calculated by the sum of all areas on the graph. "voltage / time" without voltage polarity.

Compliance is checked by inspection and testing

Contact is allowed only with parts that are separated from live parts with double or reinforced insulation.

Compliance is checked by inspection and using the test probe B according to IEC 61032 in accordance with the conditions specified in

The test probe B according to IEC 61032 is used for embedded and fixed instruments only after their installation.
