TABLE II. Conformance tests.

Tests Reference paragraph Compression set 4.5.1 Dynamic compression resistance 4.5.2 Dustiness 4.5.5 Hydrogen ion concentration 4.5.6

4.4 Test conditions. Unless otherwise specified, tests shall be conducted in an atmosphere having a relative humidity (RH) of 50 percent 5 percent and a temperature of 70 to 76 F.

Material shall be considered in equilibrium after exposure to these conditions for a minimum of 24 hours.

4.5 Tests.

4.5.1 Compression set. The test specimens shall be 6 ⅛-inch square with a minimum thickness of two inches. If the specimen is less than 2 inches thick, multiple layers shall be used.

The thickness of each specimen shall be measured prior to preworking. Preworking shall consist of compressing the specimen between parallel rigid plates to 65 percent of its thickness.

Compress a total of 10 times at a rate of approximately three times per minute. The specimens shall be allowed to recover a minimum of 4 hours after the final compression. The specimen shall then be loaded as follows: 20 pounds for type II, 30 pounds for type III, 55 pounds for type IV. The load shall be applied to the specimen evenly and gently. Three minutes after application, the load shall be removed. One minute after the load has been removed, the thickness of the specimen shall be redetermined. Specimen compression set is the difference between the preworked and final thickness expressed as a percent and calculated as follows:

Percentage compression set = (tP – tf) x 100/tp)

Where: tp = preworked thickness tf = final thickness

Five specimens shall be tested and the average compression set determined.

4.5.2 Dynamic compression resistance. A dynamic compression resistance test machine shall be used. The test machine shall consist of an instrumented, weighted drop platen and an impact base with dimensions which are at least 1 inch larger than the corresponding specimen dimensions. The weighted drop platen shall fall freely upon release onto the specimen which is supported by the impact base. The impact base shall be rigidly supported by a massive unyielding foundation. The drop platen, impact base, and supporting foundation shall be free of disturbing mechanical resonances over the frequency range 0-500 Hz. The test machine and instrumentation shall be capable of measuring the drop platen acceleration pulse generated by the cushioning specimen with an accuracy of 5 percent. The test specimen shall be an 8 by 8 inch rectangular solid, 4 inches thick, made from plies of one sample unit, if necessary. The drop platen loaded to the specified static bearing stress shall be dropped from a height of 24 inches.

At impact, drop platen, impact base, and specimen bearing surfaces shall be centered and parallel. Five drops with a 1 to 2 minute recovery interval between drops shall be made on each specimen at the static bearing stress specified in table I. Testing shall proceed in the order of increasing static bearing stress until either the test is completed or until 10 percent compression set is incurred by the specimen. When 10 percent compression set is incurred by a specimen, it shall be replaced by an untested specimen made from the same sample unit as the replaced specimen. For each static bearing stress, the five peak accelerations shall be averaged and reported as the specimen peak acceleration. The above series of tests shall be conducted on five test specimens. The second through fifth specimen peak accelerations shall be averaged for each specified static bearing stress. Average peak accelerations exceeding the limits specified in table I shall be cause for rejection of the lot.

4.5.3 Water resistance and water absorption. Five test specimens, 4 to 6 inches square and containing not less than 20 cubic inches of material shall be weighed to the nearest 0.1 gram.

Submerge the specimen for 24 hours in potable water at 75 5 F. The specimens shall be submerged a minimum of 1 inch and oriented in a manner so that a minimum of air is entrapped.

After 24 hours, remove and let drain on a wire screen for 1 minute and examine the specimens for decomposition. If the specimens are still acceptable then transfer them to a weighing dish and individually weigh to the nearest .1 gram. Specimen percent water absorbed is the difference between the final weight and the initial weight multiplied by 100 and divided by the initial weight. The percent water absorption for each of the five specimens shall be averaged to determine the sample water absorption value.

4.5.4 Tensile strength. Five test specimens shall be tested. Each specimen shall be 8 inches long and 3 inches wide and of nominal sample thickness. The two opposite ends of the specimen shall be securely clamped with a horizontal distance of 6 inches separating the clamps. A dead weight tensile load of 1.5 psi shall be applied to the specimen midway between the clamps.

Total separation of any one of the specimens within 10 minutes shall constitute failure of the lot.

4.5.5 Dusting. Five 2-inch square specimens shall be cut from each sample unit, cleaned with a brush and then weighed to the nearest 0.001 gram. A 0.75 0.01 pound cylindrical weight, having a flat face of 1.5 0.01 square inches in area shall be dropped squarely upon each specimen from a height of 10 inches above the specimen. After a total of 10 such impacts, each sample shall be cleaned with a brush and weighed to the nearest 0.001 gram. Specimen weight loss is the difference between the initial and final weighings and shall be expressed in percent of initial specimen weight. The weight losses of the five specimens shall be averaged and the average shall be reported as the sample dusting weight loss.

4.5.6 Hydrogen ion concentration (pH). Place 5 grams of air-dried cushioning material in a 500 mL heat resistant Pyrex Erlenmeyer (or equivalent) flask and add 250 mL of boiling distilled or deionized water free of CO2 and having a pH between 6.7 and 7.1. To avoid the tendency of the material to float on the surface, the flask shall be well shaken. Attach a water-cooled condenser and reflux gently for one hour with occasional shaking to ensure that all of the material is immersed in the water. Stopper the flask, cool the solution to room conditions and determine the pH of the extract electrometrically, using a glass or quinhydrone electrode and calomel cell, or colorimetrically, using isohydric indicators. The average of three separate tests shall be determined. Electrometric determination of pH is preferred for control testing.

4.5.7 Contact corrosivity. Contact corrosivity testing shall be conducted in accordance with MIL-STD-3010, Test Method 3005 using steel panels only.

PACKAGING

5.1 Packaging. For acquisition purposes, the packaging requirements shall be as specified in the contract or order (see 6.2). 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 Command. 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.
