耐火泥浆线变化率试验方法国际标准制定中的问题及应对

Problems and Countermeasures in Establishment of International Standard for Determination of Permanent Change in Dimensions on Heating of Refractory Mortars

线变化率是耐火泥浆一项重要的技术指标,目前却没有合适的试验方法国际标准。2016年12月经ISO批准,成立了第27工作组,由我国主导制定耐火泥浆线变化率试验方法国际标准。通过多次工作组会议与成员间积极交流,开展大量的试验验证工作,有效地解决了耐火泥浆线变化率试验方法国际标准制定过中出现的技术问题。

Permanent change in dimensions is an important technical index of refractory mortars,but there is no a suitable international standard for test methods at present.Approved by the ISO in December,2016,it was established the 27 th working group,led by China,formulated the international standard for determination of permanent change in dimensions on heating of refractory mortars.Through many working group meetings and active communication with members,and carry out a large number of experimental verification work,the technical problems in the process of standardsetting were well solved.
