3.3.1 Decomposition test. Specimens approximately 21.5 by 28 cm shall be cut from the samples to be tested. In separate 9 inch x 11 inch, 1-1/2” deep disposable aluminum pans, each sample shall be burried in commercial potting soil with 1% by weight organic plant fertilizer (3-5-1) and 1% weight bacteria (Hy-yield stump removal compound), the mixture shall be thoroughly mixed together just prior to burying the sample. The mixture shall be enough to form a 1-1/4 inch deep layer of mixture in each pan. The specimens shall be irregularly buried so that some edges show above the mixture and some areas are covered by as much as 1 inch of mixture. No water is to be added to the mixture. Upon burying the specimens, each pan shall be sealed in polyethylene bags and stored in the dark at room temperature (20oC to 23oC) for ten days. After this time has passed, the bags shall be opened and the specimens examnined. The specimens shall have no evidence of perceptible strength of either the paper or the mesh that has been buried. Any perceptible or measurable strength of the any of the buried paper or mesh or mesh specimens shall be cause for rejection of the lot.
3.4 Absorbency. The type I cloths shall have the absorbency capacity required by table I. The test for this shall be as follows:
3.4.1 Water. Cut specimens (10 cm x 10 cm is recommended) and weight to nearest 0.1g. Entirely immerse each sample in distilled water at 25oC for 3 minutes without movement. Remove by lifting at one corner until entire specimen is clear of the water, allow excess to drain off for 60 seconds. Place each in a tared weighing bottle and reweigh. Calculate the percent absorption to the nearest 1 percent as follows:
Percent absorption-
(Wet weight- dry weight)/dry weight) x 100
3.4.2 Oil. Same as 3.3.1 using white mineral oil, viscosity 80-90 SU (Saybolt Universal), in lieu of water.
3.5 Size. Unless otherwise specified, the individual towels shall be one of the following sizes, the dimensions specified are those of the minimum side length and the minimum overall area:
Size 1- 11 cm min. x 238 cm2 min.
Size 2- 20 cm min. x774 in cm2 min.
Size 3- 29 cm min. x 1109 cm2 min.
Size 4- 29 cm min. x 1258 cm2 min.
Size 5- 30 cm min. x 1129 cm2 min.
Size 6- 30 cm min. x 1451 cm2 min.
Size 7- 32 cm min. x 1193 cm2 min.
Size 8- 32 cm min. x 1516 cm2 min.
Size 9- 36 cm min. x 1580 cm2 min.
3.6 Unitization/packaging. The towels shall be unitized and packaged as specified by the contract or purchase order. For the lowest level of required packaging, the average package count of 10 packages randomly chosen from the lot shall be plus or minus 2 the required numbre of towels at that package level, no package shall contain 5 below the required number of towels.
3.7 Workmanship. The towels shall be free from holes, tears, dirt, spots, ragged or uneven edges, or any other defects that affect serviceability.
3.8 Commercial item. The use of the term “commercial item description” in this document does not imply that any item or items offered are not required to conform with all requirements specified herein.
