ISO/TR 79:2015概述了定性性能标准物质（RMs）的生产、认证或表征的最新进展。 许多专家认识到，生产经质量特性认证的RMs需要指导文件。与此同时，人们发现现有信息太不成熟，无法制定一份国际公认的指导文件。此外，由于缺乏定性特性的术语和定义的国际词汇表，来自不同测试领域的专家之间的交流更加困难。 ISO/TR 79总结了可用的专业知识。其目的是为正在进行的有关标称特性和此类RMs的生产的讨论做出贡献。在不同的专业领域（检查、分类、识别、测试、观察等），对标称特性的调查有不同的定义。 )ISO/TR 79试图促进国际协调指导文件的未来发展。

ISO/TR 79:2015 summarizes the state of the art of the production and certification or characterization of qualitative property reference materials (RMs). The need for guidance documents for the production of RMs certified for qualitative properties was recognized by many experts. At the same time, the available information was found to be too immature to develop an internationally accepted guidance document. Additionally, the lack of an international vocabulary for terms and definitions for qualitative properties made it more difficult for the experts from various testing areas to communicate with each other. ISO/TR 79 summarizes the available expertise. It aims to contribute to the on-going discussion on nominal properties and the production of such RMs. The investigation of nominal properties is referred to differently in various specialized areas (examination, classification, identification, testing, observation, etc.). ISO/TR 79 tries to foster the future development of an internationally harmonized guidance document.
