A Regional Metrology Organization (RMO) Key Comparison of dew/frost point temperatures over the range -30 °C TO +20 °C was carried out by the National Institute of Standards and Technology (NIST, USA) and the Laboratorio Costarricense de Metrología (LACOMET, Costa Rica), between February 2015 and August 2015. The results of this comparison are reported here, along with descriptions of the humidity laboratory standards for NIST and LACOMET 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 the degree of equivalence between the dew/frost-point standards of NIST and LACOMET.

SIM.T-K6.5 对湿度标准的双边关键比较，在 -30 °C 至 +20 °C 的def/霜点温度范围内

区域计量组织 (RMO) 对 -30 °C 至 +20 °C 范围内的露点/霜点温度进行了关键比较，由美国国家标准与技术研究院（NIST，美国）和 Laboratorio Costarricense de Metrología（ LACOMET，哥斯达黎加），2015 年 2 月至 2015 年 8 月之间。此处报告了此比较的结果，以及 NIST 和 LACOMET 的湿度实验室标准的描述以及这些标准的不确定性预算。该报告还描述了比较协议并提供了获取的数据。分析结果，确定 NIST 和 LACOMET 的露点/霜点标准之间的等效程度。
