High-density moisture-resistant wood-based composite blocks meet is exceed the following
criteria:
Density: 36.9 ? 42.1 lbs. ft3 (591 ? 675 kg/m3)
Adhesive: only approved glue and additives that can assure the stability of the blocks
can 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.

Weight change ? 25% increase
Length change ? 2% increase
Width change ? 2% increase
Height change ? 6% increase
ide 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 (fully
waterproof) adhesive. Wood-based composite blocks that exceed the limits of the tests listed in
this 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 dimension
and 50% of blocks shall meet or exceed the target dimension at the time of component
manufacture. Based on current GMP, the target length, width and height of blocks may exceed
the specified dimensions by a maximum of 3/16 in. (4.8 mm), 1/8 in. (3 mm) and 1/16 in. (1.5
mm), respectively.
The following are acceptable manufacturing tolerances allowed on established target dimensions.
Blocks
Length: +3/16 in. (+4.8 mm), -0 in. (-0 mm) maximum deviation
Width:  +1/8 in. (3 mm), -1/16 in. (1.6 mm) maximum deviation
Height: +1/16 in. (?1.6 mm) maximum deviation

Wood component placement
The 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
