1 Scope
This document presents a practical approach to the application of
measurement
uncertainty to electrical safety testing conducted within
the electrotechnical sector. It is specifically conceived for use in IECEE
Schemes as well as by testing laboratories engaged in testing electrical
products to national safety standards. It describes the application of
measurement
uncertainty principles.
This document provides guidance on making measurement
uncertainty calculations and gives some examples relating to
measurement
uncertainty calculations for product conformity assessment
testing.
NOTE The IEC Standardization Management Board (SMB) has decided that
Guides such as this one can have mandatory requirements which shall be
followed by all IEC committees developing technical work that falls within
the scope of the Guide, as well as guidance which may or may not be
followed. The mandatory requirements in this Guide are identified by the use
of "shall". Statements that are only for guidance are identified by using
the verb "should". (See ISO/IEC Directives, IEC Supplement:2021, A.1.1.)
