Inorganic filler shall constitute between 15 and 45 percent of the cement by weight when tested in accordance with 4*4.3. 3 3.2 Condition in container. The cement shall be a smooth, homogeneous mixture, not thickened or livered, and having no degree of spparafcion which cannot be easily overcome by hand stirring. 3.3 Characteristics of application. The cement shall spread readily without drawing or pulling when applied to various materials as described in 4>4*4. 3.4 Effects of temperature. 3.4.I Behavior at 60 degress C (140 degree F).

There shall be no cracking of the cement and no separation of cement and metal when tests and conducted in accordance with 4.4.5.2. 3 2 BIRD 015177 SS-C-00153A(G3A-FSS) 4. QUALITT ASSURANCE PROVISIONS 4.1 Responsibility for inspection. Unless otherwise specified in the contract or purchase order, the supplier is responsible for the performance of all inspection requirements as specified herein. Except as otherwise specified, the supplier may utilize his own facilities or any commercial labora tory acceptable to the Government. The Government reserves the right to perform any of the inspec tions set forth in the specification where such inspections are deemed necessary to assure that supplies and services conform to prescribed requirements. 4.2 Lot. Unless otherwise specified (see 6.2), a lot shall consist of all the cement from the samp production batch which is offered for delivery at one time. 4.3' Sampling. Sampling for inspection and tests shall be in accordance with MU--STD--105 Samp ling methods used shall be as described in AS2M-D140. 4.4 Test methods. 4.4.1 Flash point of solvent. The solvent shall be tested according to ASIM D1310 to determine its flash point (see 3.1.1.2). 4.4.2 Percentage of nonvolatile matter. Transfer about 10 grains of the sample into a previously weighed flat-bottomed metal dish approximately 3 inches in diameter. Weigh dish and contents. Heat the dish and its contents in an oven at 105 to 110 degrees C (221 to 230 degrees F) for a period of 24 hours. Allow the dish to cool to room temperature and weigh "the dish and contents. Compute the percentage of nonvolatile matter using the following formula (see 3-1.2 and 3.1-3): Percentage of nonvolatile matter = C-A --B-A Where: A = weight of the dish. B = weight of dish and original sample. C = weight of dish and sample after heating. 4.4.3 Percentage of inorganic filler. Transfer from 5 to 10 grams of the sample into a previously weighed porcelain crucible. Weigh the crucible and contents to the nearest 0.01 gram. Heat the crucible and its contents at a low heat (not above a dull red) until all carbon is consumed. Reweigh the crucible and residue and compute the percentage of Inorganic material as follows (see 3.1.2 and 3-1.3): Percentage of inorganic filler = Z-X ^ Where: X = weight of crucible. X - weight of crucible and original sample. Z = weight of crucible and residue after heating. 4.4.4 Preparation of test panels. Prepare specimens of smooth-surfaced asphalt prepared roofing (heavyweight), asphalt saturated flashing felt, and clean plate steel approximately 4 by 6 inches In size. Trowel cement'onto each of the three specimens to.a thickness of 1/16 to 1/8 inch (see 3-3). Bribed a thread in the coating of each of the three test samples, not more than 2 inches from the top edge of the sample, measuring the exact distance from the top. 4.4-5 Tests for reaction to high and low temperatures.. 4.4.5.1 Test for behavior at 60 degrees C (140 degrees F). Place the test panels prepared in 4*4-4 in a horizontal position in a well ventilated room at a temperature not below 15 degrees C (59 degrees F), but not in the direct rays of the sun, for a period of 60 minutes. Then, suspend the panels vertically in an oven at a temperature of 60 degrees C (140 degrees F) for a period of 5 hours. Remove the panels from the oven and examine for blistering. Then, measure the distance from the top to the embedded thread and compare with the measurement recorded in 4.4-4 in order to determine the amount of slippage (see 3.4.I). 3 BIRD 015178 SS-C-00153A(GSA-FSS) 4.4.5-2 Test for behavior at 0 degress C (32 degrees Fl. Cool the steel test panel used in 4.4.5.1 to room temperature and then immerse it in a water bath at 0 degrees C (32 degrees F) for a period of 1 hour. Immediately upon rsrmving the panel from the bath, bend it around a mandrel which is 1 inch in diameter, at a uniform bend rate requiring approximately 2 seconds to complete. Dry the panel thoroughly and examine it irr conformance to the requirements of 3.4.2. 4.5 Inspection of preparation for delivery. An inspection shall be made to determine that the packaging, packing and marking requiremsrrs comply with section 5. 5. PREPARATION FOR DELIVERY 5,1 Packing. Packing shall be level A, B or C as specified (see 6.2). 5.1.1 Level A and B. Five gallons of cement shall be packed in a 29 gage metal pail conforming to PPF-P-704, Type II or III. The wire bail shall be zinc coated or otherwise protectively coated to resist corrosion. All exterior surfaces of the level B pail shall have a commervial coating. Vlhen specified pails shall be palletized in accordance with MIL-STD-147. 5.1.2 Level C. Cement shall be packed to insure carrier acceptance and safe delivery at destina tion at the lowest rates, in containers complying with the rules and regulations applicable to the mode of transportation. 5.2 Marking. In addition to markings required by the contract or order the unit and shipping containers ahull be marked in accordance with Fed. Std. No. 123 or MIL-STD-129. 6. NOTES 6.1 Intended use. The cement covered by this specification is intended for use in the construc tion of plastic flashings for bituminous roofing, for repair of bituminous and metal roofing, and as an expansion joint material for concrete erd masonry construction. 6.2 Ordering data.
