标准范围

ISO 834的本部分规定了在以下情况下确定柱耐火性应遵循的程序:自行测试。立柱通常在所有侧面完全暴露于加热的情况下进行测试。然而，在实践中，暴露是必须从少于四个侧面复制适当的暴露条件。当结构符合要求时，可将本试验应用于其他未经测试的结构形式适用于ISO 834本部分中给出的直接应用领域，或适用于扩展应用时根据ISO/TR 12470进行分析。由于ISO/TR 12470只给出了一般性指南，具体的应用分析只能由耐火结构专家进行。本试验方法的一般指南见附录A。

This part of ISO 834 specifies the procedures to be followed for determining the fire resistance of columns whentested on their own.Columns are normally tested with all sides fully exposed to heating. However, when in practice the exposure isfrom fewer than four sides, appropriate exposure conditions have to be reproduced.The application of this test to other untested forms of construction is acceptable when the construction complieswith the direct field of application as given in this part of ISO 834 or when subjected to an extended applicationanalysis in accordance with ISO/TR 12470. Since ISO/TR 12470 gives only general guidelines, specific extendedapplication analyses are to be performed only by persons expert in fire-resistant constructions.General guidance on this test method is given in annex A.
