IEC 61326 pdf download – Electrical equipment for measurement, control and laboratory use – EMC requirements
1Scope
This International Standard specifies minimum requirements for immunity and emissions regardingelectromagnetic compatibility (EMC) for electrical equipment, operating from a supply of less
than 1 00o V a.c.or 1 500 v d.c. or from the circuit being measured, intended for professional,industrial-process and educational use, including 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 usedwithout additional testing.
Where a relevant dedicated EMC standard exists, it shall take precedence over all aspects ofthis product-family standard.
The following equipment is covered in this standard.a) Electrical measurement and test equipment
This is equipment which by electrical means measures, indicates or records one or moreelectrical or non-electrical quantities,also non-measuring equipment 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,with eachvalue determined by manual settings, by local or remote programming, or by one or moreinput variables.This includes industrial process measurement and control (iPMC)
equipment, which consists of devices such as:
process controllers and regulators;
programmable controllers (PC);
power supply units of equipment and systems (centralized or dedicated);-analogue/digital indicators and recorders;
– process instrumentation;
– transducers, positioners, intelligent actuators, etc.c) Electrical laboratory equipment
This is equipment which measures, indicates, monitors or analyses substances, or is usedto prepare materials.
This standard is applicable to
equipment for use in industrial locations;
equipment for use in laboratories or test and measurement areas with a controlledelectromagnetic environment;
test and measurement equipment which is portable and powered by battery or from thecircuit being measured.
This equipment may also be used in areas other than laboratories.
