This test method for fire tests covers marine joiner door assemblies of various materials and types of construction for use in bulkhead openings to retard the passage of fire. Tests made in conformity with this test method will register performance during the test exposure; but such tests shall not be construed as determining suitability for use after exposure to fire. Tests made in conformity with this test method will develop a set of data to assist regulatory agencies to determine the suitability of joiner door assemblies for use in locations where fire resistance is required. This test method should be used to measure and describe the properties of materials, products, or assemblies in response to heat and flame under controlled laboratory conditions and should not be used to describe or appraise the fire hazard or fire risk of materials, products, or assemblies under actual fire conditions. However, results of this practice may be used as elements of a fire risk assessment that takes into account all of the factors that are pertinent to an assessment of the fire hazard of a particular end use. The values stated in SI units are to be regarded as the standard. This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
