A key comparison in dew-point temperature in the range of +30 C to +95 C was carried out among the national standards held by NMIJ (pilot), MSL (coordinator), RCM-LIPI/SNSU-BSN, SCL, KRISS, NMIM, NMIA, NIMT, CMS/ITRI, and NMC, A*STAR. The purpose of the comparison was to establish the degree of equivalence between realizations of local scales of dew point temperature of humid gas among the participating national institutes. Although the comparison schedule was considerably delayed, no significant drift of the transfer standard was observed over the whole period of the comparison. The result of a chi-squared test demonstrated that the comparison was effective, and the results obtained in the comparison can be used as reliable supporting evidence for CMCs that each participant claims.

APMP 湿度比较的最终报告 APMP.T−K8:露点温度 +30 C 至 +95 C

在NMIJ(试点)、MSL(协调员)、RCM-LIPI/SNSU-BSN、SCL、KRISS、 NMIM、NMIA、NIMT、CMS/ITRI 和 NMC、A*STAR。比较的目的是在参与的国家机构之间建立当地湿气露点温度标度的实现之间的等效程度。尽管比较计划被大大延迟,但在整个比较期间没有观察到转移标准的显着漂移。卡方检验的结果表明比较是有效的,比较中获得的结果可以作为每个参与者声称的CMC的可靠支持证据。
