ASTM F1994-99(2023)

4.1.1?Foam systems for machinery spaces are tested using those portions of this test method which apply to the installed components. Suitable adaptation of this test method is made for use with systems which do not include all hardware components described herein.

4.1.2?Deck foam systems are tested in accordance with the manufacturers design criteria.

4.2.1?This test method verifies application rates and areas of coverage for each type of discharge device of the fixed foam firefighting system.

4.2.2?The satisfactory operation of the system in the selected zones is a measure of overall system capacity and anticipated operation for emergency use. The test, however, may not be representative of all emergency operating conditions that may vary with changes in the number of zones that are activated simultaneously, the material condition of the distribution and sprinkling components as they are maintained over time, and restoration of the system following its use for testing or actual emergencies.

4.3.1?Tests accomplished in accordance with approved test procedures may be sufficient to demonstrate that the vessel meets the regulatory and classification requirements for the vessel.

4.3.2?Approval of test procedures by a classification society may be necessary.

4.3.3?Test procedures must state operating parameters and values (for example, flow rate, pressure, time to activate) which define pass/fail criteria for each test.

4.5.1?Leakage at any piping system mechanical joint that is corrected on-the-spot is not cause for test rejection.

4.5.2?Any erratic operation detected in the zone control valves, seawater sprinkling pump discharge bypass-overboard valves, or control devices is cause for rejection of the test. The component causing the erratic operation shall be repaired or replaced and a retest performed.

4.5.3?Any operation which does not meet the pass/fail criteria defined by the test procedure(s) is cause for rejection of the test. The cause of the failure shall be determined, the design or installation, or both, corrected as appropriate, and a retest performed.

1.4.1?International requirements, national regulations, and ship classification rules must be consulted. The following regulatory requirements and classification society rules were considered in the preparation of this test method:

1.5?The values stated in inch-pound units are to be regarded as standard. No other units of measurement are included in this standard.

1.6?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.

1.7?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.
