Fire safety caution passing a fire test in a controlled laboratory setting and or certifying or labeling a product as having a one hour two hour or any other fire resistance or protection rating and therefore as acceptable for use in certain fire rated assemblies systems does not mean that either a particular assembly system. 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. The ratings relate to fire tests designed to determine how quickly fire can raise the temperature to unacceptable levels.
