Problems and countermeasures in establishment of ISO standard for test methods of thermal shock resistance of refractories

doi:10.3969/j.issn.1001-1935.2021.02.019

Abstract

Abstract:

Thermal shock resistance is one of the most important performances of refractories.There are many test methods for measuring thermal shock resistance in China and overseas,but there is no a universal international standard.Approved by the ISO in August 2016,China established the international standard for test method of thermal shock resistance for refractories by actively exchanging with members of working groups in China and overseas,and carrying out a good deal of test verification work.The technical problems during the establishment process were well solved and the international standard was officially issued in October 2020.

Key words: thermal shock resistance, test method, ISO standard

摘要：

抗热震性是耐火材料最重要的使用性能之一,国内外有多种测定抗热震性的试验方法,但是还没有统一的国际标准。2016年8月经ISO批准,由我国主导制定耐火材料抗热震性试验方法国际标准,通过与国内外工作组成员积极交流,并开展大量的试验验证工作,较好地解决了制定过程中出现的技术问题,2020年10月该国际标准正式发布。
