4、recision and BiasSection 11 Key WordsINTRODUCTIONPassive 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 ev
5、aluated 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, F
6、ire 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 w
7、e add a 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

Scope1.1 The purpose of the specification is to evaluate insulationinstalled on steel or aluminum structural division as d

Lower levels of fireresistance will be allowed wit
