Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Main text A Regional Metrology Organization (RMO) Key Comparison of dew/frost point temperatures was carried out by the The Federal State Unitary Enterprise "All-Russian Scientific Research Institute of Physical, Technical and Radio Engineering Measurements" (VNIIFTRI, Russia) and the RSE "Kazakhstan Institute of Standardization and Metrology" (KazStandard, Kazakhstan) between September, 2024 and February, 2025. The results of this comparison are reported here, along with descriptions of the humidity laboratory standards for VNIIFTRI and KazStandard and the uncertainty budget for these standards. This report also describes the protocol for the comparison and presents the data acquired. The results are analyzed, determining degree of equivalence between the dew/frost-point standards of VNIIFTRI and KazStandard. To reach the main text of this paper, click on Final Report .
