IEC 61326-1-2020 pdf free download – Electrical equipment for measurement, control and laboratory use – EMC requirements – Part 1: General requirements.
This part of lEC 61326 specifies requirements for immunity and emissions regarding electro-magnetic compatibility (EMC) for electrical equipment,operating from a supply or battery ofless than 1 000V AC or 1 500 v DC or from the circuit being measured. Equipment intendedfor professional,industrial-process， industrial-manufacturingand educational use is coveredby this part. It includes equipment and computing devices for
– measurement and test;
– control;
-LABORATORY use;
– accessories intended for use with the above (such as sample handling equipment),intended to be used in industrial and non-industrial locations.
Computing devices and assemblies and similar equipment within the scope of informationtechnology equipment (ITE) and complying with applicable iTE EMC standards can be used in
systems within the scope of this part of lEC 61326 without additionaltesting，if they aresuitable for the intended electromagnetic environment.
lt is generally considered that this product family standard takes precedence over thecorresponding generic EMC standards.
The following equipment is covered by this document.a) Electrical measurement and test equipment
This is equipment which, by electrical means, measures, indicates or records one or more
electrical or non-electrical quantities, also non-measuringequipment such as signalgenerators, measurement standards, power supplies and transducers.
b) Electrical control equipment
This is equipment which controls one or more output quantities to specific values,witheach value determined by manual settings, by local or remote programming，or by one ormore input variables. This includes industrial process measurement and control(IPMC)equipment, which consists of devices such as:
– process controllers and regulators;
– programmable controllers;
– power supply units for equipment and systems (centralized or dedicated);
– analogueldigital indicators and recorders;
– process instrumentation;
– transducers, positioners, intelligent actuators, etc.
c) Electrical LABORATORY equipment, including In Vitro Diagnostic (IVD) medical equipment
This is equipment used to prepare or analyse materials,or measure，indicate or monitorphysical quantities. This equipment might also be used in areas other than laboratories.
d) Equipment a), b) or c) as above when being equipped with components having radio functionality, for example for wireless communication.
Equipment within the scope of this document might be operated in different electromagnetic environments; depending on the electromagnetic environment different emission and immunity test requirements are applicable.
This document considers three types of electromagnetic environments:
BASIC ELECTROMAGNETIC ENVIRONMENT ;
INDUSTRIAL ELECTROMAGNETIC ENVIRONMENT ;
CONTROLLED ELECTROMAGNETIC ENVIRONMENT .
Corresponding immunity test requirements are described in Clause 6.
In terms of emission requirements, equipment shall be classified in Class A or Class B equipment, as per the requirements and procedure of CISPR 11. The corresponding emission requirements are described in Clause 7.
The specified emission and immunity requirements aim at achieving electromagnetic compatibility between equipment covered in this document and other equipment that might operate at locations with electromagnetic environments considered in this document.
Guidance for an assessment concerning the risk for achieving EMC is given in Annex B.
