本欧洲标准规定了用于确定耐火材料（包括成型和非成型产品）的高温测量锥体当量（耐火性）的方法。其有用的应用范围取决于适用的高温测量参考锥的可用性。在1500°C至1800°C的温度范围内，适用于EN 993-13中规定的高温测量参考锥。由于高温测量参考锥体主要用于估算温度对硅质，低氧化铝耐火粘土和耐火粘土产品的影响，所以除了这些材料以外的材料的结果可能不是精确的

This European Standard specifies a method for determining the pyrometric cone equivalent (refractoriness) for refractory materials including shaped and unshaped products. Its useful range of application depends on the availability of suitable pyrometric reference cones. In the temperature range from 1500 °C to 1800 °C, the pyrometric reference cones specified in EN 993-13 are suitable. As pyrometric reference cones are primarily manufactured for estimating the effect of temperature on siliceous, low alumina fireclay and fireclay products, the results on materials other than these may not be as precise.
