P-class phasor measurement unit algorithms using adaptive filtering to enhance accuracy at off-nominal frequencies [PDF]
, 2011 While the present standard C.37.118-2005 for Phasor Measurement Units (PMUs) requires testing only at steady-state conditions, proposed new versions of the standard require much more stringent testing, involving frequency ramps and off-nominal frequency ...

IAPSO Standard Seawater: definition of the uncertainty in the calibration procedure, and stability of recent batches [PDF]
, 2007 Standard seawater (SSW) has been employed by oceanographers as a reference material in the determinationof salinity for over a century. In all that time, this is the first study to determine the uncertaintyof the SSW manufacturing process.

Development of a certified reference material for specific surface area of quartz sand
Стандартные образцы, 2017 The paper presents results of conducting research on the development of a certified reference material (CRM) for specific surface area of quartz sand, which is practically non-porous and therefore has low specific surface area value ~ 0.8 m2/g.
