(Test Method)Standard Test Method for Shock Testing of Structural Insulation of A-Class Divisions Constructed of Steel or Aluminum
Standard Test Method for Shock Testing of Structural Insulation of A-Class Divisions Constructed of Steel or Aluminum
ABSTRACT
This specification covers a method for evaluating insulation installed on steel or aluminium structural division as defined in IMO resolution A. 754 (18) to assure insulation is note degraded in the event of shock. The non-combustible passive fire protection insulation shall be installed to meet the highest level of commercial fire resistance expected. Lower levels of fire resistance will be allowed without additional shock level testing. This testing method is used to measure and describe the response of materials, products, or assemblies to heat and flame under controlled conditions. This specification also provides guidelines for shock test before conducting a fire resistance test. In the shock test, the fire resistant divisions, bulkheads and decks shall be tested according to the specifics required by the MIlL-S-901D, Section 3.2.1 (b) Medium Weight Shock Test.
SIGNIFICANCE AND USE
4.1 This test method evaluates the ability of a non-combustible passive fire protection system installed on structural divisions on commercial ships to function after shock loading.
4.2 The shock loading is accomplished by conducting impact testing of a test specimen consisting of insulation on a standard steel or aluminum structural core installed on a medium weight shock test machine.
4.3 Following the shock testing the shocked test specimen and an unshocked test specimen are tested for fire resistance. Both shocked and unshocked test specimens are installed side-by-side in a fixture and fire tested at the same time.
4.4 The fire resistance for both specimens is measured and recorded.
4.5 Other passive fire protection systems using the same insulation materials and attachment methods and having lower fire resistance ratings will be accepted without additional shock testing.
SCOPE
1.1 The purpose of the specification is to evaluate insulation installed on steel or aluminum structural division as defined in IMO Resolution A.754 (18) to ensure the insulation is not degraded in the event of a shock.
1.2 The non-combustible passive fire protection insulation shall be installed, which will meet the highest level of commercial fire resistance expected. Lower levels of fire resistance will be allowed without additional shock testing.
1.3 This test method is used to measure and describe the response of materials, products, or assemblies to heat and flame under controlled conditions, but does not by itself incorporate all factors required for fire-hazard or fire-risk assessment of the materials, products or assemblies under actual fire conditions.
1.4 Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests.
1.5 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the 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.

INTRODUCTION
Passive fire protection materials have been required and used on commercial ships for decades.The
passive systems include the non-combustible insulation material and its means of attachment to steel
or aluminum divisions. The passive system has been evaluated in a standard fire test using a standard
steel or aluminum structural core. No impact loading has been required prior to testing for fire
resistance.
The United States Navy requires shock testing of passive fire protection prior to fire resistance
testing; this test is defined in MIL-STD-3020, Fire Resistance of U.S. Naval Surface Ships, 7
November, 2007. The technology to economically shock test the passive fire protection systems was
developed 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 level of shock
protection to our passive fire protection systems on commercial ships where appropriate. Many of the
passive fire protection systems used today are mechanically fastened and will perform the intended
function after a shock event.
Passive fire protection insulation may have thermal or acoustic treatments added to the insulated
division. These treatments add mass to the fire protection system and their effect on shock is not
included in this specification.
