UL 2431耐火涂料和材料的耐久性
发布日期：2022-8-25 9:10:52 阅读次数：3494
UL 2431-2014 Safety for Durability of Fire Resistive Coatings and Materials
UL 2431-2014 防火涂料和材料的耐久性安全
UL 2431标准范围
1.本标准旨在提供一种方法，用于测量耐火材料在经受各种调节环境后保持其耐火性能的能力。耐火性能是通过测量受材料保护的钢管、宽法兰段和钢板的温度来确定的。
2. 描述了各种类型的调节环境。调节环境包括空气侵蚀、湿循环、冻循环和干循环、湿度、抗冲击性、工业大气、盐雾、温度稳定性、紫外线和振动。
3. 定义了两种火灾暴露，正常温升火灾和快速温升火灾。正常温升火灾旨在代表一场充分发展的内部建筑火灾。快速升温火灾旨在代表油气藏火灾。
4调节环境和火灾暴露试验并不代表所有暴露和火灾条件。关于火灾暴露，条件随火灾荷载的数量、性质和分布的变化而变化:通风；隔间大小和配置；以及安装耐火材料的隔间的导热和散热特性。
In brief, UL 1709 describes test methods for two types of exposure, as follows:
Full-scale fire exposure—Full-scale fire exposure testing is intended to evaluate the thermal resistance of PFP materials applied to full-scale structural steel columns, and the ability of PFP materials to withstand fire exposure.
Small-scale fire exposure—Small-scale fire exposure testing is intended to evaluate the ability of PFP materials applied to small-scale structural steel columns to withstand fire exposure as well as a variety of environmental conditions. Durability is assessed using tests similar to those found in UL 2431, Durability of Spray-Applied Fire Resistive Materials.
