This part of ISO 10295 provides guidance in respect of a structured method of characterizing the penetrating<\/p>\n
seal under test utilizing a series of defined parameters, each one being determined by the use of a selected<\/p>\n
series of test configurations in conjunction with simulated services. The level of characterization being sought<\/p>\n
is dependent upon the classification requirement of the system, which in turn determines the complexity of the<\/p>\n
test program. It is also intended the test method addresses the influence the supporting construction has on<\/p>\n
the performance of the seal system.<\/p>\n
The methods described apply to the determination of data relating to single component penetration seals where<\/p>\n
the penetration service does not melt out within the appropriate period of exposure to a fully developed fire.<\/p>\n
The selection of the appropriate system depends upon many factors. Of particular importance is the size of the<\/p>\n
penetration, since penetration seal systems are frequently penetration size (or size range) specific.<\/p>\n
This is a guidance document, its purpose being to determine the critical parameters relating to the performance<\/p>\n
of the seal being evaluated. Such parameters can then be used as a basis for interpolation and\/or extrapolation<\/p>\n
of the seal's performance. The procedures used have been developed utilizing small square penetrations,<\/p>\n
single component penetration seals, and cylindrical conductors; however it is possible to generate a similar<\/p>\n
series of tests using rectangular cross-section conductors if this is more appropriate to end use.<\/p>\n
This part of ISO 10295 provides a structured approach designed to establish<\/p>\n
\u2014 the mode of failure;<\/p>\n
\u2014 the parameters critical to the performance of the penetration seal under test.<\/p>\n
The mode of failure and critical parameters are ascertained using test configurations appropriate to the potential<\/p>\n
performance of the product, in conjunction with clearly defined standard penetrations.<\/p>\n
The results gained from the application of this technical report are designed to assist a suitably qualified person<\/p>\n
to develop a direct and extended field of application for the penetration seal under test using in particular, the<\/p>\n
principles and methodology given in ISO\/TR 12470. Using the field(s) of application so generated, it should be<\/p>\n
possible to classify the penetration seal, thus facilitating its incorporation into specifications.<\/p>\n
The test configurations recommended in this part of ISO 10295 are not appropriate for evaluating multicomponent<\/p>\n
penetration seals.<\/p>\n
This part of ISO 10295 is not appropriate for characterizing all types of penetration seals, e.g. pipe closers\/collars<\/p>\n
and some gland systems, for which evaluation using ISO 10295-1 is more appropriate.<\/p>\n
This part of ISO 10295 does not address the distance required between services that can generate their own<\/p>\n
heat. When a live service is being evaluated, it is necessary to give consideration to the distance required<\/p>\n
between penetrations.<\/p>\n","protected":false},"excerpt":{"rendered":"
