南京睿督分享：钢结构防火涂料EN13381-4耐火试验

关于EN 13381-4 (钢构件防火涂料)

这是建筑钢结构防火领域最常用的标准之一。如果你的产品是直接涂抹或包覆在钢梁、钢柱上的防火涂料或防火板，那么应遵循此标准。

标准名称：EN 13381-4-2014 确定结构构件耐火性能的试验方法 - 第4部分:对钢构件的被动保护

测试内容：该标准旨在评估防火保护系统在火灾（遵循EN 1363-1标准升温曲线）下，保持自身结构完整并附着在钢材上，以及有效隔热（减缓钢材升温）的能力。不同厚度防火涂料耐火试验怎么检测和计算。

适用性：标准主要针对I型钢或H型钢等截面进行测试。测试结果可通过特定的计算方法（如截面系数插值）应用于其他类型的钢构件。

重要限制：该标准适用于被动防火材料，不适用于膨胀型防火涂料（Reactive fire protection materials）。膨胀型防火涂料另有标准（EN 13381-8）进行测试。

Part 4 of the European Standard series 13381 specifies a test method for determining the contribution made by applied passive fire protection systems to the fire resistance of structural steel members, which can be used as beams or columns. It considers only sections without openings in the web. It is not directly applicable to structural tension members without further evaluation. Results from analysis of I or H sections are directly applicable to angles, channels and T-sections for the same section factor, whether used as individual elements or as bracing. This European Standard does not apply to solid bars or rods. This European Standard covers fire protection systems that involve only passive materials and not reactive fire protection materials as described in this document. The evaluation is designed to cover a range of thicknesses of the applied fire protection material, a range of steel sections, characterised by their section factors, a range of design temperatures and a range of valid fire protection classification periods. This European Standard describes the fire test procedures, which specifies the tests which should be carried out to determine the ability of the fire protection system to remain coherent and attached to the steelwork, and to provide data on the thermal characteristics of the fire protection system, when exposed to the standard temperature/time curve specified in EN 1363-1. The fire test methodology makes provision for the collection and presentation of data, which can be used as direct input to the calculation of fire resistance of steel structural members in accordance with the procedures given in EN 1993-1-2 and EN 1994-1-2. 

欧洲标准系列13381第4部分规定了用于确定施加的被动防火系统对结构钢构件(可作为梁或柱使用)耐火性能贡献的测试方法。该方法仅适用于腹板中无开口的截面。若未经进一步评估，则不直接适用于无结构张力的构件。对I或H截面进行分析所得结果，对于相同的截面系数而言，可直接适用于角钢、槽钢和T 形截面，无论其被用作独立构件还是作为支撑结构。本欧洲标准不适用于实心条或棒材。本欧洲标准所涵盖的防火系统仅涉及被动材料，不涉及本文件中描述的活性防火材料。评估旨在涵盖所应用防火材料的厚度范围、各种钢构件(以其截面系数为特征)、设计温度范围以及有效的防火分类周期范围。本欧洲标准描述了火灾测试程序，其中详细规定了为确定防火系统保持连贯性和附着于钢结构的能力、以及提供防火系统在暴露于EN 1363-1中规定的标准温度/时间曲线时的热特性数据而应进行的测试。火灾测试方法学为数据的收集和呈现提供了
规定，这些数据可作为直接输入，用于根据EN 1993-1-2和EN 1994-1-2中给出的程序计算钢结构构件的耐火性能。
