Scope

This document specifies requirements for immunity and emissions regarding electromagnetic
compatibility (EMC) for electrical equipment, operating from a supply or battery of less than
1,000 V AC or 1,500 V DC or from the circuit being measured.
Equipment intended for professional, industrial-process, industrial-manufacturing and
educational use is covered by this document. 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 information
technology equipment (ITE) and complying with applicable ITE EMC standards can be used
in systems within the scope of this document without additional testing, if they are suitable for
the intended electromagnetic environment.
It is generally considered that this product family standard takes precedence over the
corresponding 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-measuring equipment such as
signal generators, measurement standards, power supplies and transducers.
b) Electrical control equipment.
This is equipment which controls one or more output quantities to specific values,
with each value determined by manual settings, by local or remote programming, or
by one or more input variables. This includes industrial process measurement and
control (IPMC) equipment, which consists of devices such as.
