3、easurement statement(1.5)in October 2013.INTRODUCTIONPassive fire protection materials have been required and used on commercial ships for decades.Thepassive systems include the non-combustible insulation material and its means of attachment to steelor aluminum divisions.The passive system has been
4、evaluated in a standard fire test using a standardsteel or aluminum structural core.No impact loading has been required prior to testing for fireresistance.The United States Navy requires shock testing of passive fire protection prior to fire resistancetesting;this test is defined in MIL-STD-3020,Fi
5、re Resistance of U.S.Naval Surface Ships,7November,2007.The technology to economically shock test the passive fire protection systems wasdeveloped 50 years ago,and equipment in commercial laboratories is available.After the terrorist attack on September 11,2001 it is our responsibility that we add a
6、 level of shockprotection to our passive fire protection systems on commercial ships where appropriate.2Many of thepassive fire protection systems used today are mechanically fastened and will perform the intendedfunction after a shock event.Passive fire protection insulation may have thermal or aco
7、ustic treatments added to the insulateddivision.These treatments add mass to the fire protection system and their effect on shock is notincluded in this specification.TABLE OF CONTENTSIntroductionSection 1ScopeSection 2Referenced DocumentsSection 3TerminologySection 4Significance and UseSection 5Sho

12、 will be allowed without additional shock testing.1.3 This test method is used to measure and describe theresponse of materials,products,or assemblies to heat and flameunder controlled conditions,but does not by itself incorporateall factors required for fire-hazard or fire-risk assessment of themat
13、erials,products or assemblies under actual fire conditions.1.4 Fire testing is inherently hazardous.Adequate safe-guards for personnel and property shall be employed inconducting these tests.1.5 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard.The val
14、ues stated ineach system may not be exact equivalents;therefore,eachsystem shall be used independently of the other.Combiningvalues from the two systems may result in non-conformancewith the standard.1.6 This standard does not purport to address all of thesafety concerns,if any,associated with its u
