OIML Work on Electricity Meters
TC 12 - R46

Information
– R46 currently pertains only to “active energy meters” and does not
include apparent/reactive energy or demand measurement

TC12 anticipates developement of requirements pertaining to reactive
meters subsequent to the finalization of this Recommendation
– Some sections of CD2 are incomplete and will require further
development
– CD2 has removed requirements pertaining to statistical sampling at
this time. Final decision pending work performed by TC3/SC4
which is tasked to address this subject
– Significant progress was made towards the development of
metrological, technical and testing requirements during the Ottawa
meeting.
OIML Work on Electricity Meters
TC 12 - R46

Issues and Subject Matters
– Technical/metrological concerns
 Some resistance to accept requirements which differ from IEC standards
 Proposals from some members to establish requirements which are
technology dependant, (electo-mechanical meters vs. static meters)
– R46 includes requirements pertaining to verification.
 Individual jurisdictions may establish their own verification programs
designed to meet the needs in that jusrisdiction and such programs do not
constitute a technical barrier to trade.
– R46 establishes four different levels of accuracy class.
 It should be clear that individual legislative authorities can identify the
accuracy class(es) which are acceptable in their jurisdiction
 R46 makes a recommendation as to the minimum accuracy class to be used
for metering large consumers


Develop Sampling Plan and Methods
for the verification of utility meters
– CD1 issued in April 2004
– TC3/SC4 meeting was held in Germany
on September 15-17, 2004
– Meeting report in OIML Bulletin (April
2005, p. 51-53)
– CD2 should be issued early in 2006

•
the document includes meter test requirements which
should be covered in another OIML Recommendation
lot formation and homogeneity principles
the "spare meter" rules in the document are too lax and
would encourage abuse
the LQ = 8.0% control criterion has not been selected on
any objective basis (focus was placed on sample sizes
only)
only one single extension (equal to half the original meter
reverification period) is offered in the document
new CD to be produced as a result of comments.
