• Phạm vi áp dụng / Scope of standard: 1.1 This standard 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 E 119. 1.3 The wall assembly shall sustain the applied load during a standard fire exposure specified in Test Methods E 119 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 and health practices and determine the applicability of regulatory limitations prior to use.
