This Technical Specification supplements the requirements of EN ISO/IEC 17025:2005, and is suitable for the
demonstration of competence of laboratories that undertake periodic measurement of emissions from
stationary sources including
the taking of representative samples of emissions and subsequent laboratory analysis for gases and for
particulate species,
the determination of reference quantities such as temperature, pressure, water vapour and oxygen
content in the field and
the use of portable instruments (such as hand held instruments and transportable instruments used in
mobile laboratories) in the field.
This Technical Specification is applicable to all laboratories undertaking the periodic measurement of
emissions from stationary sources, the calibration of installed automated measuring systems in accordance
with EN 14181:2004 and/or the field testing of automated measuring systems for conformity assessment
purposes.
