1、Designation: D5572 95 (Reapproved 2012)Standard Specification forAdhesives Used for Finger Joints in Nonstructural LumberProducts1This standard is issued under the fixed designation D5572; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revi
2、sion, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification establishes performance levels foradhesives to be used in finger joints in nonstr
3、uctural bonded-lumber products. Such products include, but are not limited to,interior and exterior mouldings, window and door componentsor parts, and bonded-lumber panels. Adhesives that meet therequirements of the various performance classes are consideredcapable of providing an adequate bond for
4、use under theconditions described for the class. This specification is to beused to evaluate adhesives as well as the adhesive bonds in thefinger joints. See Section 5, Significance and Use, for limita-tions when using this specification to evaluate industriallymanufactured finger joints.NOTE 1This

Test Requirements4.1 Adhesives:4.1.1 To comply with this specification the test adhesiveshall be tested for performance in accordance with Section
19、s8.1.1-11, and it shall meet the requirements in Table 1 for theselected testing mode and performance classification.4.1.2 Compliance with this specification shall warrant cer-tification of the adhesive for use on the species of wood that isused for the tests, or for use on a designated group of spe
20、cieswhen tested and found to be in compliance for any one memberof said group of species. The designated species groupings forcommonly used domestic and imported woods, as accepted inthis specification, are given in Table 2. In the event that the useror supplier of the adhesive, or both, cannot acce
21、pt the desig-nated groupings in Table 2, either party shall have the option ofrequesting a test on an individual species. Furthermore, theuser and supplier may agree to change any of the wood-failurerequirements of Table 1 when applied to tests on Groups 3 and4 hardwoods from Table 2. For wood-prope
22、rty information onimported woods, see the Wood Handbook.44.1.2.1 The wood-failure requirements listed in Table 1 aregiven for softwoods and hardwoods. Table 1 shows that thewood-failure requirements for hardwood are 50 % of therequirements for softwoods.4.2 Industrially Manufactured Finger JointAn i
23、ndustri-ally manufactured finger joint may be used to evaluate theadhesive, provided its construction meets the requirements setforth in Sections 7-10, and the joint is tested against therequirements in Table 1.5. Significance and Use5.1 Adhesives are classified as dry use or wet use. Eachclassifica
