UL 2431耐火涂料和材料的耐久性
發布日期:2022-8-25 9:10:52 閱讀次數:4207
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標準范圍
1.本標準旨在提供一種方法,用于測量耐火材料在經受各種調節環境后保持其耐火性能的能力。耐火性能是通過測量受材料保護的鋼管、寬法蘭段和鋼板的溫度來確定的。
2. 描述了各種類型的調節環境。調節環境包括空氣侵蝕、濕循環、凍循環和干循環、濕度、抗沖擊性、工業大氣、鹽霧、溫度穩定性、紫外線和振動。
3. 定義了兩種火災暴露,正常溫升火災和快速溫升火災。正常溫升火災旨在代表一場充分發展的內部建筑火災。快速升溫火災旨在代表油氣藏火災。
4調節環境和火災暴露試驗并不代表所有暴露和火災條件。關于火災暴露,條件隨火災荷載的數量、性質和分布的變化而變化:通風;隔間大小和配置;以及安裝耐火材料的隔間的導熱和散熱特性。
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.
