| Nosaukums | <p>This part of ISO 10295 provides guidance in respect of a structured method of characterizing the penetrating</p> <p>seal under test utilizing a series of defined parameters, each one being determined by the use of a selected</p> <p>series of test configurations in conjunction with simulated services. The level of characterization being sought</p> <p>is dependent upon the classification requirement of the system, which in turn determines the complexity of the</p> <p>test program. It is also intended the test method addresses the influence the supporting construction has on</p> <p>the performance of the seal system.</p> <p>The methods described apply to the determination of data relating to single component penetration seals where</p> <p>the penetration service does not melt out within the appropriate period of exposure to a fully developed fire.</p> <p>The selection of the appropriate system depends upon many factors. Of particular importance is the size of the</p> <p>penetration, since penetration seal systems are frequently penetration size (or size range) specific.</p> <p>This is a guidance document, its purpose being to determine the critical parameters relating to the performance</p> <p>of the seal being evaluated. Such parameters can then be used as a basis for interpolation and/or extrapolation</p> <p>of the seal's performance. The procedures used have been developed utilizing small square penetrations,</p> <p>single component penetration seals, and cylindrical conductors; however it is possible to generate a similar</p> <p>series of tests using rectangular cross-section conductors if this is more appropriate to end use.</p> <p>This part of ISO 10295 provides a structured approach designed to establish</p> <p>— the mode of failure;</p> <p>— the parameters critical to the performance of the penetration seal under test.</p> <p>The mode of failure and critical parameters are ascertained using test configurations appropriate to the potential</p> <p>performance of the product, in conjunction with clearly defined standard penetrations.</p> <p>The results gained from the application of this technical report are designed to assist a suitably qualified person</p> <p>to develop a direct and extended field of application for the penetration seal under test using in particular, the</p> <p>principles and methodology given in ISO/TR 12470.
