3、hesand beams,should be at least equal to that of the wood.Because initial strength tests generally are notan adequate measure of integrity of adhesive joints under severe service conditions,a test thatsimulates the effects of exterior exposure has been devised to evaluate adhesive joints in structur
4、allaminated wood members intended for this type of service.1.Scope1.1 These test methods cover an accelerated means ofmeasuring the resistance to delamination of structural lami-nated wood members intended for exterior service.1.2 These test methods are not intended as substitutes orreplacements for
5、 the more severe test of resistance to delami-nation in Specification D2559.1.3 Two test methods are included.Choice of test methoddepends on purpose of the test and available time to complete.1.3.1 Test Method AThis test requires 3 days to completeand is a method for determining the suitability of
6、adhesives andmanufacturing techniques and equipment for production ofjoints adequate for exterior service.1.3.2 Test Method BThis test requires approximately 1212h.(If excessive delamination occurs,the cycle is repeated).Itis a quality-control type test for examining adhesive jointquality.1.4 The va
