Standard Practice for Application of Hose Stream

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 rating of building elements.

This practice specifies the water pressure and duration of exposure or application of the hose stream to the test assembly.

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

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

Pass/fail criteria are defined in the appropriate fire test method.

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.

Scope:

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 UnitsThe values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

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 fire standard cannot be used to provide quantitative measures.

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.
