4.1 These test methods provide uniform methods for inspection and test of rubber hoses that can be referenced in hose specifications for various applications.4.2 Uniform test methods make quality comparisons of hose easier and more meaningful, and are more economical particularly when the same rubber vulcanizates are used in different types, constructions, or sizes of hose.1.1 These test methods cover procedures for inspection and test of all types and constructions of rubber hose.21.2 In case of conflict between provisions of these test methods and those of detailed specifications or test methods for a particular hose, the latter shall take precedence.1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.1.4 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

4.1 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 of building elements.4.1.1 This practice specifies the water pressure and duration of application of the hose stream to the test assembly.4.2 This practice is intended to be used only after a test assembly has completed a prescribed standard fire-resistance test.4.3 The practice exposes a test assembly to a standard hose stream under controlled laboratory conditions.4.3.1 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.4.4 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 The 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.8 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
