ISO 10295的本部分提供了有关表征渗透性的结构化方法的指南使用一系列定义的参数进行测试的密封件，每个参数由选定的结合模拟服务的一系列测试配置。所寻求的特征化水平取决于系统的分类要求，这反过来又决定了系统的复杂性测试程序。试验方法还旨在解决支撑结构对结构的影响密封系统的性能。所述方法适用于确定与单组分贯穿件密封件相关的数据，其中在暴露于充分发展的火灾的适当时间内，贯穿件不会融化。选择合适的系统取决于许多因素。特别重要的是贯穿件，因为贯穿件密封系统通常针对贯穿件尺寸（或尺寸范围）。这是一份指导文件，其目的是确定与性能相关的关键参数正在评估的密封件。然后，这些参数可以用作插值和/或外推的基础对密封性能的评估。使用的程序是利用小型方形贯穿件开发的，单组分贯穿件密封件和圆柱形导体；然而，也有可能产生类似的结果如果更适合终端使用，则使用矩形横截面导线进行一系列试验。ISO 10295的这一部分提供了一种结构化方法，旨在建立-失败模式；-对被测贯穿件密封性能至关重要的参数。故障模式和关键参数是使用适合于潜在故障的测试配置确定的产品性能，以及明确定义的标准贯穿件。从应用本技术报告中获得的结果旨在帮助合适的合格人员为了开发测试中渗透密封的直接和扩展应用领域，特别是使用ISO/TR 12470中给出的原则和方法。使用这样生成的应用程序字段，应该可以对贯穿件密封进行分类，从而便于将其纳入规范。ISO 10295本部分中推荐的试验配置不适用于评估多组分贯穿件密封件。ISO 10295的本部分不适用于描述所有类型的贯穿件密封件，例如管道闭合器/套环以及一些压盖系统，使用ISO 10295-1进行评估更合适。ISO 10295的这一部分没有说明可以生成自己的服务的服务之间所需的距离热在评估实时服务时，有必要考虑所需的距离在穿透之间。

This part of ISO 10295 provides guidance in respect of a structured method of characterizing the penetratingseal under test utilizing a series of defined parameters, each one being determined by the use of a selectedseries of test configurations in conjunction with simulated services. The level of characterization being soughtis dependent upon the classification requirement of the system, which in turn determines the complexity of thetest program. It is also intended the test method addresses the influence the supporting construction has onthe performance of the seal system.The methods described apply to the determination of data relating to single component penetration seals wherethe penetration service does not melt out within the appropriate period of exposure to a fully developed fire.The selection of the appropriate system depends upon many factors. Of particular importance is the size of thepenetration, since penetration seal systems are frequently penetration size (or size range) specific.This is a guidance document, its purpose being to determine the critical parameters relating to the performanceof the seal being evaluated. Such parameters can then be used as a basis for interpolation and/or extrapolationof the seal's performance. The procedures used have been developed utilizing small square penetrations,single component penetration seals, and cylindrical conductors; however it is possible to generate a similarseries of tests using rectangular cross-section conductors if this is more appropriate to end use.This part of ISO 10295 provides a structured approach designed to establish— the mode of failure;— the parameters critical to the performance of the penetration seal under test.The mode of failure and critical parameters are ascertained using test configurations appropriate to the potentialperformance of the product, in conjunction with clearly defined standard penetrations.The results gained from the application of this technical report are designed to assist a suitably qualified personto develop a direct and extended field of application for the penetration seal under test using in particular, theprinciples and methodology given in ISO/TR 12470. Using the field(s) of application so generated, it should bepossible to classify the penetration seal, thus facilitating its incorporation into specifications.The test configurations recommended in this part of ISO 10295 are not appropriate for evaluating multicomponentpenetration seals.This part of ISO 10295 is not appropriate for characterizing all types of penetration seals, e.g. pipe closers/collarsand some gland systems, for which evaluation using ISO 10295-1 is more appropriate.This part of ISO 10295 does not address the distance required between services that can generate their ownheat. When a live service is being evaluated, it is necessary to give consideration to the distance requiredbetween penetrations.
