seal under test utilizing a series of defined parameters, each one being determined by the use of a selected

series of test configurations in conjunction with simulated services. The level of characterization being sought

is dependent upon the classification requirement of the system, which in turn determines the complexity of the

test program. It is also intended the test method addresses the influence the supporting construction has on

the performance of the seal system.

The methods described apply to the determination of data relating to single component penetration seals where

the 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 the

penetration, 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 performance

of the seal being evaluated. Such parameters can then be used as a basis for interpolation and/or extrapolation

of 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 similar

series 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 potential

performance 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 person

to develop a direct and extended field of application for the penetration seal under test using in particular, the

principles and methodology given in ISO/TR 12470. Using the field(s) of application so generated, it should be

possible 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 multicomponent

penetration seals.

This part of ISO 10295 is not appropriate for characterizing all types of penetration seals, e.g. pipe closers/collars

and 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 own

heat. When a live service is being evaluated, it is necessary to give consideration to the distance required

between penetrations.

The methods are suitable for rooms with volumes of approximately 300 cubic metres or less in e.g. dwellings, hotels, schools, offices and hospitals. The standard is not in general intended for measurements in large auditoria such as concert halls. However, the operating conditions and operating cycles in Annex B can be used in such cases.

The service equipment sound-pressure level is determined as the maximum A-weighted and optionally C-weighted sound-pressure level occurring during a specified operation cycle of the service equipment under test, or as the equivalent continuous sound-pressure level determined with a specified integration time. A-weighted and C-weighted values are calculated from octave-band measurements.

ISO 15758:2014 is applicable when the temperature of the medium in the pipe is above 0 °C. It applies to pipes inside buildings as well as in the open air.

ISO 10295-1:2007 assesses the effect of such penetrations on the integrity and insulation performance of the element concerned, the integrity and insulation performance of the penetration sealing system, the insulation performance of the penetrating service or services, and where appropriate, the integrity failure of a service.

ISO 10295-1:2007 does not provide information concerning the influence of the inclusion of such penetrations and sealing systems on the load-bearing capacity of the element.

It is possible that a penetration seal is a component of, or contributes to the performance of, a system to which special requirements apply. In such cases additional tests, relevant to the system and its function, can be necessary. Examples are chimneys and fire-rated ducts in air distribution systems.

ISO 10295-1:2007 is not intended to provide quantitative information on the rate of leakage of smoke and/or hot gases or on the transmission or generation of fumes. Such phenomena are to be noted in describing the general behaviour of specimens during test.

ISO 10295-1:2007 does not provide information on the ability of the seal to withstand stresses that can be caused by the movement or displacement of the penetration services in practice.

It is not the intention of this part of ISO 10295-2:2009 to provide quantitative information on the rate of leakage of smoke and/or gases, or on the transmission or generation of fumes, although such phenomena can be recorded in describing the general behaviour of specimens during the test. It is not the intention of this part of ISO 10295-2:2009 to evaluate joint seals where special test procedures already exist, e.g. doors, partitions, penetrations, pipes, ducts and cables.

a) airborne sound insulation between rooms,

b) impact sound insulation of floors,

c) airborne sound insulation of façades, and

d) sound pressure levels in rooms caused by service equipment.

The methods described in this document are applicable for measurements in rooms of dwellings or in rooms of comparable size with a maximum of 150 m³.

For airborne sound insulation, impact sound insulation and façade sound insulation the method gives values which are (octave band) frequency dependent. They can be converted into a single number characterising the acoustical performances by application of ISO 717-1 and ISO 717-2. For heavy/soft impact sound insulation, the results also are given as A-weighted maximum impact sound pressure level. For service equipment sound the results are given directly in A – or C -weighted sound pressure levels.
