This part of IEC 61010 specifies general safety requirements for electrical equipment intended for professional, industrial process, and educational use, any of which may incorporate computing devices, as defined in a) to d) below, when used under the environmental conditions of 1.4.
a) Electrical test and measurement equipmentThis is equipment which by electrical means tests, measures, indicates or records one or more electrical or non-electrical quantities, also non-measuring equipment such as signal generators, measurement standards, power supplies, transducers, transmitters, etc.
NOTE All indicating and recording electrical measuring instruments (except those excluded in 1.1.2) fall within the scope of IEC 61010 unless they are panel meters designed only for building-in to other equipment. Built-in panel meters are considered to be components and only need to meet the relevant requirements of IEC 61010, or other standards, as part of the equipment into which they are built.
b) Electrical control equipmentThis is equipment which controls one or more output quantities to specific values, with each value determined by manual setting, by local or remote programming, or by one or more input variables.
c) Electrical laboratory equipmentThis is equipment which measures, indicates, monitors or analyses substances, or is used to prepare materials, and includes in vitro diagnostic (IVD) equipmentThis equipment may also be used in areas other than laboratories, for example self-test IVD equipment may be used in the home.
d) Accessories intended for use with the above (for example, sample handling equipment).
1.1.1DV.1 Modification of item (a) by adding the following:
This Part 1 applies to test equipment integrated into manufacturing facilities intended for testing electronic devices, including silicon wafers and other semiconductor devices.
NOTE This equipment is likely to be installed adjacent to and interconnected with industrial machinery in this application.
This standard does not apply to equipment within the scope of
a) IEC 60065 (Safety requirements for audio, video and similar electronic apparatus);
b) IEC 60204 (Controls for electrical machines);
c) IEC 60335 (Safety of household and similar electrical appliances);
d) IEC 60364 (Electrical installations of buildings);
e) IEC 60439-1 (Low-voltage switchgear and controlgear assemblies);
f) IEC 60521 (Class 0,5; 1 and 2 alternating current watthour meters);
g) IEC 60601 (Medical electrical equipment);
h) IEC 60950 (Safety of information technology equipment including electrical business equipment, except as specified in 1.1.3);
i) IEC 61558 (Power transformers, power supply units and similar).
This standard applies only to computers, processors, etc. which form part of equipment within the scope of this standard or are designed for use exclusively with the equipment.
NOTE Computing devices and similar equipment within the scope of IEC 60950 and conforming to its requirements are considered to be suitable for use with 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 this standard. If hazards from moisture or liquids could affect equipment that conforms to IEC 60950 and is used with equipment which conforms with this standard, the instructions for use should specify any additional precautions required.
1.1.3ADV Addition of the following referencing the National Electrical Code and the Canadian Electrical Code:
This standard applies to equipment to be employed in accordance with ANSI/NFPA 70, National Electrical Code® (NEC); designed to be installed in accordance with the Canadian Electrical Code (CEC), Part I, CSA C22.1, and CSA C22.2 No. 0; or designed to comply with both the NEC and CEC.
The purpose of the requirements of this part 1 is to ensure that the design and methods of construction used provide adequate protection for the OPERATOR and the surrounding area against
a) electric shock or burn (see clause 6);
b) mechanical hazards (see clauses 7 and 8);
c) excessive temperature (see clauses 9 and 10);
d) spread of fire from the equipment (see clause 9);
e) effects of fluids and fluid pressure (see clause 11).
f) effects of radiation, including lasers sources, sonic and ultrasonic pressure (see clause 12);
g) liberated gases, explosion and implosion (see clause 13).
NOTE Attention is drawn to the existence of additional requirements which may be specified by national authorities responsible for the health and safety of labour forces.
This standard does not cover
a) reliable function, performance or other properties of the equipment not related to safety;
b) effectiveness of transport packaging;
c) EMC requirements, which are covered by IEC 61326;
d) protective measures for explosive atmospheres (see IEC 60079);
e) servicing (repair);
f) protection of servicing (repair) personnel.
NOTE Servicing personnel are expected to be reasonably careful in dealing with obvious HAZARDS, but the design should protect against mishap by the use of warning labels, shields for hazardous voltage TERMINALS, segregation of low-voltage circuits from hazardous voltages, etc. More important, servicing personnel should be trained to recognize unexpected HAZARDS and to react accordingly.
This standard also specifies methods of verifying, through inspection and type testing, that the equipment meets the requirements of this standard.
NOTE Requirements for ROUTINE TESTS are given in annex f.
This standard applies to equipment designed to be safe at least under the following conditions:
a) indoor use;
b) altitude up to 2 000 m;
c) temperature 5 °C to 40 °C;
d) maximum relative humidity 80 % for temperatures up to 31 °C decreasing linearly to 50 % relative humidity at 40 °C;
e) mains supply voltage fluctuations up to ±10 % of the nominal voltage;
f) transient overvoltages typically present on the MAINS supply.
NOTE The normal level of transient overvoltages is impulse withstand (overvoltage) category II of IEC 60364-4-443.
g) applicable RATED POLLUTION degree.
This standard applies to equipment designed to be safe not only in the environmental conditions specified in 1.4.1, but also in any of the following conditions for which the equipment is RATED by the manufacturer:
a) outdoor use;
b) altitude above 2 000 m;
c) ambient temperatures below 5 °C or above 40 °C;
d) relative humidity above the levels specified in 1.4.1;
e) mains supply voltage fluctuations exceeding ±10 % of the nominal voltage.
