適用范圍：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 ℃ to 1800 ℃, 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.
