IEC 61010-1 pdf download.Safety requirements for electrical equipment for measurement, control, and laboratory use
1 Scope and object
1 .1 Scope
1 .1 .1 Equipment included in scope This part of IEC 61 01 0 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 equipment This 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 61 01 0 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 61 01 0, or other standards, as part of the equipment into which they are built. b) Electrical control equipment This 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 equipment This is equipment which measures, indicates, monitors or analyses substances, or is used to prepare materials, and includes in vitro diagnostic (IVD) equipment This 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 .2 Equipment excluded from scope 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 61 558 (Power transformers, power supply units and similar). 1 .1 .3 Computing equipment 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 to this standard, the instructions for use should specify any additional precautions required.
1 .2 Object
1 .2.1 Aspects included in scope 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 1 0); d) spread of fire from the equipment (see clause 9); e) effects of fluids and fluid pressure (see clause 1 1 ); f) effects of radiation, including lasers sources, and sonic and ultrasonic pressure (see clause 1 2); g) liberated gases, explosion and implosion (see clause 1 3). 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. 1 .2.2 Aspects excluded from scope 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 61 326; 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.
