Scope

1.1 This practice is to be used to evaluate the elevated temperature performance of adhesives used in end-jointed lumber.

1.2 A symmetric wall assembly containing end-jointed lumber studs is exposed to a standard fire exposure specified in Test Methods E119.

1.3 The wall assembly shall sustain the applied load during a standard fire exposure specified in Test Methods E119 for a period of 60 min or more.

1.4 This practice is used to evaluate the performance of adhesives used in end-jointed lumber to heat and flame under controlled conditions, but it does not by itself incorporate all factors required for fire hazard or fire risk assessment under actual fire conditions.

1.5 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered 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.

Significance and Use

5.1 End-jointed lumber studs used in fire resistance-rated assemblies shall be able to support the superimposed design load for the specified time under an elevated temperature exposure, when a wall assembly is exposed to a standard fire specified in Test Methods E119. Light-weight wood assemblies utilize gypsum wallboard or other types of membrane protection to accomplish a requisite fire resistance rating for the assembly. However, wood studs and the end joints in the studs shall resist the developed elevated temperature environment for the duration of the rating. This practice provides a method for evaluating the elevated temperature performance of an adhesive used in end-jointed lumber as compared with the elevated temperature performance of solid wood.
