According to the engineered wood association a one hour rating indicates that a wall constructed in a manner similar to the one tested will contain flames and high temperatures and support its full load for at least one hour after the fire begins.

Fire barriers can resist fire for up to three hours as long as the supporting structures have the same level of fire resistance.
