High-density moisture-resistant wood-based composite blocks meet is exceed the followingcriteria:Density: 36.9 – 42.1 lbs. ft3 (591 – 675 kg/m3)Adhesive: only approved glue and additives that can assure the stability of the blockscan be used as bonding agents The minimum performance requirements of the blocks. Tests are described for ANNEX E.Table 2. Minimum Wood-based Composite Component Quality.TEST MINIMUM PERFORMANCE24-hour block soak testWeight change ? 25% increaseLength change ? 2% increaseWidth change ? 2% increaseHeight change ? 6% increaseide tine compression test ? 1,400 lbf. at 9 in./min.Nail insertion force test ? 500 lbf. at 1.5 in./min.Nail withdrawal force test ? 310 lbf. at 1.5 in./min.All wood-based composite used for block components shall be bonded with exterior (fullywaterproof) adhesive. Wood-based composite blocks that exceed the limits of the tests listed inthis Section as a result of their manufacturing process are not permitted to be used for new,repaired or remanufactured pallets. Wood-based composite blocks shall have target length, width and height uniform in dimensionand 50% of blocks shall meet or exceed the target dimension at the time of componentmanufacture. Based on current GMP, the target length, width and height of blocks may exceedthe specified dimensions by a maximum of 3/16 in. (4.8 mm), 1/8 in. (3 mm) and 1/16 in. (1.5mm), respectively.The following are acceptable manufacturing tolerances allowed on established target dimensions.BlocksLength: +3/16 in. (+4.8 mm), -0 in. (-0 mm) maximum deviationWidth: +1/8 in. (3 mm), -1/16 in. (1.6 mm) maximum deviationHeight: +1/16 in. (?1.6 mm) maximum deviation Wood component placementThe placement of wood components shall be as follows:* All leading deckboards shall be within ?1/4 in. (?6 mm) of their specified location.* Other wood components shall be within ?1/2 in. (?13 mm) of their specified location,except that bottom boards shall not extend into
