Prepare 2 specimens approximately one foot square from 18 gage (0.0516 inch thick) zinc coated steel. Clean the specimens' in accordance with method A, procedure 3 in ASTM D609 except -that hand brushing and scrubbing may be used in place of power brushing. Mask a strip, approximately 1 by 12 inches along one edge Tor the specimen used in 4.4.2.2. 4.4.2.2 Brushing. With the specimen at 75 plus or minus 5C^` and the panel on horizontal surface apply the coating using a brush, at the rate of 50 plus or minus 5 square feet per gal lon. Pry specimen, remove tape and measure thickness of asphalt coat and bare zinc coated steel using a micrometer (see 3.2.2.1). 4.4.2.3 Spraying. Using a standard heavy material spray gun equipped with a 1/4 inch In ternal mixing nozzle and employing a maximum air pressure on the coating pump and gun nozzle at 80 lbs. per square inch, spray the compound onto the specimen held in a 45'Plus car minus 5 an gular position from the horizontal, to an average wet film thickness of l/l6 inch (see 3.2.2.2). 4.4.3 Nonvolatile material. Weigh approximately 10 grains of the sample in a tared flat bottom metal dish about 8 cm. in diameter or in a friction tpp can plug. Heat the dish with Its contents in an oven at 325F. plus or minus 5F* for five hours or at 221F. plus or minus 5?* for 24 hours; cool and weigh. Pram the weight of the residue in the dish and from the weight of the original sample taken, compute the percentage of nonvolatile matter (see 3.3.I). 4.4.4 Mineral filler. Determine mineral filler or. stabilizer In accordance with ASTM DI65 (see 3.3.2). 4.4.5 Water content. Determine water content in accordance with ASTM D95 (see 3*3*3) 4.4.6 Behavior at IkcPF. (see 3.3-4).' 4.4.6.1 Specimens. Prepare 4 specimens measuring approximately 6 inches by 10 inches. Two specimens shall be obtained frcm smooth surfaced asphalt prepared roofing weighing approximately 55 pounds per 108 square feet in accordance with ASTM D224. The remaining two specimens shall be obtained fran 22 gage (0-0336 inch thick) zinc coated steel. Clean the steel specimens in accar- ' dance with Method A, Procedure 1, In ASEM D609. 4.4.6.2 Template. Prepare a template from 18 gage - (0.0478 inche3 thick) steel sheet. Length and width of the template shall be the same as the specimens in 4.4.6.1. ' Cut a rectangular hole measuring approximately 3 inches by 7 inches out of the center. 4.4.6.3 Procedure. Using the template apply roof coating at the rate of. approximately 1 gallon per 50 square feet to the 4 test specimens over a 3 inch by 7 inch area, as follows: (a) Place reference lines on the specimens 1-1/2 and 1-1/4 Inches fran the bottom, and 1-1/2 inch from the top extending the width of .the specimens. (b) Place template over each specimen in turn so that the opening coincides with the l-l/2 inch reference lines. (c) Apply a generous amount at coating filling the opening and level off using the edge of a vide metal scraper. Hold scraper at approximately 45 angle. (d) Hold template firmly to prevent sagging or slipping while scraping down the roof coat ing, noting that the surface of the coating Is lower than the template due to the draw down characteristics. After scraping remove the template. Within five minutes after applying the roof coating place the specimens in an oven at 140 plus, or minus 2F. and position the specimens at an angle of approximately 30 to the horizontal. Remove the specimens after 5 hours. Examine both the roofing and metal for sagging or slipping beyond the bottom l-l/2 inch reference line. Examine only the metal specimens for blistering. 4.4.7 Behavior at 32F. Cool the two coated metal specimens used in 4.4.6.3 to room tem perature and inmerse in an ice-water mixture for one hour. Bimedlately after their removal from the bath, bend the specimens at a uniform rate, in approximately 2 seconds time, over a 1-inch mandrel, with the coating on the outside. Dry thoroughly and examine for cracking and adhesion (see 3.3*5)* 4 SS-A-006V4c(GSA-FSS) 4.4.8 Settling, properties (see 3.3.6). ; . - .. . 4.4.8.X Test cylinder. Prepare a test cylinder as follows: . (a) Cut a 2-1/2 inch (NPS) steel pipe to approximately 9 Inches in length. Chamfer inside edge to remove burrs. (b) Tap a 1-inch bole centered 2-5/lfi inch from the top. Insert a short threaded plug such that the end is flush with the inside wall of the. cylinder. (c) Cut or machine a disc l/4 inch thihk to fit flush inside the bottom of the cylinder. Seal after assembly. ; (d) Scribe a line on the inside vail i-lnch from the top. (e) Prepare a piece of alum-rmim foil to cover the test cylinder. Use a 2 pound weight to hold the foil in place. 4.4.8.2 Procedure. Stir coating until it appears to be-homogeneous. Heat approximately a 1 quart sample and the teat cylinder to approximately 120P and fill to the engraved line. HLace covered cylinder in an oven at 120F plus or minus 2F for 72 hour period. Remove from oven. Immediately unscrew plug from cylinder and collect all drainings during a 3 minute period. Tho roughly mix an drainings and run ash content determination. Compare with ash content of the orig inal sample. Use a 1 to 2 gram sample to determine ash content and record as percent of total roof coating. If no material drains frcm .the outlet at the conclusion of the 72 hour test, or if the ash content of the final sample is at least 80 percent of the .original, the coating passes this test. .5.
