Standard Practice for Application of Hose Stream

2010-12-31 /Historical
Superseeded by:
Significance and Use:

This practice is intended to standardize the apparatus used and the method or pattern of application of a standard hose stream to building elements as one part of the assessment and fire resistance classification of building elements.

This practice is intended to be used only after a test assembly has completed a prescribed standard fire endurance test.

The practice exposes a test assembly to a standard hose stream under controlled laboratory conditions.

4.3.1 Water pressure and duration of exposure are not specified in this practice. Duration of exposure, water pressure, and pass/fail criteria are defined in the appropriate fire test method.

4.3.2 This exposure is not intended to replicate typical fire fighting operations or all applied or impact loads a system could be subjected to in field use and conditions.

Any variation from tested conditions has the potential of substantially changing the performance characteristics determined by this practice.


1.1 This practice is applicable to building elements required to be subjected to the impact, erosion, and cooling effects of a hose stream as part of a fire-test-response standard. Building elements include, but are not limited to, wall and partition assemblies, fire-resistive joint systems, and doors.

1.2 This practice shall register performance of the building element under specific hose stream conditions. It shall not imply that, either after exposure or under other conditions, the structural capability of the building element is intact or that the building element is suitable for use.

1.3 The result derived from this practice is one factor in assessing the integrity of building elements after fire exposure. The practice prescribes a standard hose stream exposure for comparing performance of building elements after fire exposure and evaluates various materials and construction techniques under common conditions.

1.4 Units—The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the practice. Within the text, the SI units are shown in brackets.

1.5 The text of this standard references notes which provide explanatory material. These notes shall not be considered as requirements of the standard.

1.6 This standard is used to measure and describe the response of materials, products, or assemblies to heat and flame under controlled conditions, but does not by itself incorporate all factors required for fire risk assessment of the materials , products, or assemblies under actual fire conditions.

1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
