Regardless of the cause of splitting, the split shall be straddled with additional fasteners when the split is more than 3 inches in length. Open splits with visible fastener shanks or legs shall be limited as follows. No more than one open split with a visible fastener shank or leg per connection shall be permitted and not more than one-third of the components per pallet shall contain open splits with visible fastener shanks or legs at the completion of manufacture.

3.2.1.3.2. Shakes. Shakes (see 6.4) shall be considered as splits (see 3.2.1.3.1) when the shake goes through the entire thickness of the board. Shakes running the full thickness of a component and longer than 3 inches shall be straddled with additional fasteners in the top and bottom deckboards.

3 .2.1.3 .3. Season checks. Season checks (see 6.4) which extend through the board shall be considered as splits (see 3.2.1.3.1). Season checks running the full thickness of a component and longer than 3 inches shall be straddled with additional fasteners in the top and bottom deckboards.

The moisture content shall be tested with an electric type moisture meter (see 6.15) or by one of the oven drying methods of ASTM 04442. If a moisture meter is used, the meter shall be capable of reading moisture contents as high as 30 percent with a minimum accuracy of plus or minus one percent of true moisture content. Three readings shall be taken from each blank, and if any one of the three measurements of moisture content fails to meet the requirements of 3 .2.1.4, the lot shall be rejected.

4.4.2. Presence of Copper-8-quinolinolate preservative. An ordinary glass tube eye dropper shall be used to deliver two drops of PQ80 surface to the wood surface. An immediate dark brown coloration and the spreading of the drops shall indicate Copper-8-quinolinolate treatment. Alternatively, the PQ80 surface indicator may be substituted with a formulation containing 10 parts by weight, of Sodium diethyldithiocarbamate trihydrate (see 6.10) and 90 parts by weight of distilled water.

4.4.3. Presence of Zinc Naphthenate preservative. Dissolve 0.1 grams of dithizone

(diphenylthiocarbazone) (see 6.11) in either 100 ml of Methyl ethyl ketone or 100 ml of Chloroform (Note: This solution may be stored for long periods of time.) An ordinary glass tube eye dropper shall be used to deliver five drops of the solution to the wood surface. The indicator turns red when zinc is present. The color green indicates that the preservative is not present. Both colors fade quickly in the presence of light.

4.4.4. Presence of Copper Naphthenate preservative. An ordinary glass tube eye dropper shall be used to deliver two drops of PQ80 surface indicator to the wood surface. The stain will tum a dark brown color and the spreading of the drops shall indicate Copper-8-quinolinolate treatment. Alternatively, the

PQ80 surface indicator may be substituted with a formulation made by dissolving 0.5 grams Chrome azurol S concentrate (see 6.12) and 5.0 grams Sodium acetate in 80 ml of distilled water and then dilute further to 500 ml total with distilled water. Then a common manual (fly) type applicator shall be used to spray the solution over the surface of dried treated wood. The indicator turns a deep blue color when copper is present.

4.4.5. Concentration level. The concentration level of the applicable preservative shall be calculated and recorded prior to utilization and every 8 hours of use thereafter by following the preservative supplier's recommended ratio of product to water (see 6.13).

4.4.6. Deckboard width. Measurements for overall width of deckboards shall be performed by measuring across the fastener area with an ordinary tape measure. There is a potential of misrepresentation of the deckboard width ifthe measurements are taken at mid-span. The wood members tend to shrink due to wood cell moisture loss after construction which could cause boards to be nonconforming.

4.4.7. Pallet squareness. Measurements for overall pallet squareness shall be performed by measuring the diagonals from one comer to another with an ordinary tape measure.

5. PACKAGING.

5.1. Packaging. For acquisition purposes, the packaging requirements shall be as specified in the contract or order. When packaging of materiel is to be performed by DOD or in-house contractor personnel, these personnel need to contact the responsible packaging activity to ascertain packaging requirements. Packaging requirements are maintained by the Inventory Control Point's packaging activities within the Military Service or Defense Agency, or within the military service's system commands. Packaging data retrieval is available from the managing Military Department's or Defense

Agency's automated packaging files, CD-ROM products, or by contacting the responsible packaging activity.
