Scope

This test method evaluates the temperature transmission performance of an encapsulation material or assembly of materials installed over a wood substrate when the test specimen is subjected to a standard fire exposure condition following the standard time-temperature curve as described in Section 6 - Test Conditions.  

It is the intent that the encapsulation period established by this test method indicates the period of standard fire exposure when an encapsulated structural timber element is not expected to reach temperatures sufficient to cause charring or combustion, potentially resulting in contribution to fire severity, and shall not be construed as having determined the fire endurance period of the encapsulation material or assembly of materials, or of the structural timber element.

It is the intent that the encapsulation period established by this test method indicates performance only during the fire exposure period and shall not be construed as determining suitability for use after fire exposure.

Project need:

Project Need
To develop a new test standard that evaluates the ability of an encapsulating material to protect a substrate material (e.g. wood) when exposed under fire conditions.
