Impact
and Scope of Standard
BS EN-14181 (and EN-13284-2 for particulate are
important standards
focussed on the quality assurance of Automatic Monitoring Systems (AMS)
and
measuring emissions with defined uncertainty.
In all member EU states, these new
standards are being applied in Waste
Incineration (WID) and Large Combustion Plant (LCPD).
In the UK,
they may also be applied to
certain IPPC regulated plant on a case by case basis, instead of
alternative
continuous monitoring strategies where the environmental benefit
justifies the
cost.
PCME manufacture a specific range of
instruments designed to meet these
exacting standards. This
range is
distinct to PCME’s other range of products which meet
alternative and
pre-existing regulatory standards.
A key
factor in the successful implementation of this standard is process
operator,
test house and instrument manufacturer working in partnership to
supply,
calibrate and operate instruments in full compliance to the standard. PCME and its service
partners are committed
to providing the highest level of application and service support and
the very
best in certified instruments to play their crucial role in the
EN-14181
partnership.
