If the cube root as calcu lated proves to be a fractional number, it shall be expressed as the nett higher whole number. For convenience, the following table is given, showing" the number of rolls to be taken from shipments of various sizes: Rolls in shipment: Up to 1000 1001-1728 1729-2744 2745-4096 4097-5832 5833-8000 8001-10648 10649 and over Number of rolls taken 5 6 7 8 9 10 11 12 F-2- Inspection.--The sample rolls taken shall he inspected to determine compliance with this specification with respect to work manship, condition, width, and weight. F-2*. Net weight of roll.--Each sample roll taken shall be weighed intact to the nearest Yi pound, numbered, and its weight recorded. F-2b. Weight per 100 square feet of saturated and coated felt.-- The width and length of each sample roll taken shall Be measured to the nearest % inch. From these measurements and the weight obtained in paragraph F-2a, calculate the weight per 100 square feet of saturated and coated felt by the following formula: Weight in pounds. ------------------------- ------------------- x 100 = Weight per 109 .... width in inches 12Length in feet x ------------------------ square feet If the calculated weight per 100 square feet of saturated and coated felt of any sample roll is less than 17 pounds for the 20- pound class (class A) or less than 50 pounds for the 50-pound class (class B), additional rolls equal to twice the number origi nally sampled shall be inspected. If the calculated weight per 100 square feet of any of these additional rolls is less than the mini mum specified, the entire lot shall he rejected by the inspector and no samples taken for laboratory examination. F-3. Sampling for laboratory examination.--From the sample rolls, examined in sampling for inspection, select one the weight of which m nearest the average weight of the whole lot. Unroll, and at approximately 10 feet from the outside end cut two samples the full width "of the roll and approximately 40 inches long. The sheet shall be cut at right angles to the edge of the roll. Measure and weigh the strips and calculate the weight per 100 square feet of each. Discard any strip whose weight varies by more than 0.6 pound from the weight obtained in paragraph F-2b. Divide each strip into four equal parts, identifying the inside of the roll and 4 4 i c BIRD 005986 FEDERAL STANDARD- STOCK CATALOG (Section IV. Part B) the direction of the fiber grain on each section. (The direction of the fiber grain is parallel to the edge of the roll.) Label and pack flat between supports wide and stiff enough to prevent crushing. Transmit one sample (the four sections cut from one sheet) to the testing laboratory and retain the other for check tests if necessary. F-4. Laboratory examination.-- F-4a. Weight.--Assemble the pieces- and trim the sample so that it is 36 inches long and the full width of the roll. Measure accurately and weigh to the nearest gram (15 grains). From the measurements an.d weight so obtained compute the weight per 100 square feet by the following formula: W_e_i_g-h--t--i-n--g--r-a--m--s---x---3--1-.-7 Area in square inches Weight in pounds per 100 square f,ee.t The weight so determined is to be used in selecting samples for laboratory examination and shall not be used as a basis for ac ceptance or rejection. (See par. F-2b.) F-4b- Appearance.--Examine both sides of the sample to de termine compliance with the requirements of paragraph C-2. F-4c. Pliability.--At a distance pot leas than 3 inches from the edge of the sample cut five strips 1 inch-wide and 6 inches long in the direction of the fiber grain, and immerse them in water at 25* C. (77 F.) for 10 to 15 minutes. Remove the strips indi vidually from the water and immediately bend each strip, with the surface corresponding to the inside of the roll uppermost, through an arc of 90 over the rounded corner of a block (radius as speci fied below) at a uniform speed in approximately 2 seconds' time. Dry thoroughly and examine.. If one or more of these five strips crack on this test, cut 10 strips from another part of the sample and repeat the test. If one or more of thesestrips crack, the material shall be reported as failing in the pliability test Cracks less than % inch in length at the edge of the test strip shall Be disregarded. Class A--%-inch radius. Class B--%,-inch radius. F-4d- Volatile matter at 105 to 110" C. (SSI* to 230 P-).-- Cut two strips of the felt 6 inches wider and 12 inches long, weigh the strips separately to the nearest 0J. gram and suspend them for 5 hours in an'oven at 105' to 110 C. (221 to 230 F.). Remove from the oven, cool in a desiccator, and weigh. Compute the loss in weight for each strip and report the average as the percentage of volatile matter in the sample. F-4e Weight of deeaturated felt.--Cut a strip 2 inches wide representing the full width of the sample, measure to the nearest y inch, and weigh to the nearest milligram. From this data calculate the weight of 100 square feet of material. If`this weight varies by more than 0.5 pound from that determined in paragraph F-4a, discard and cut additional strips until one within this limit is obtained. S22aS?~* FEDERAL STANDAW STOCK CATALOG (Section IV, Part 6) F-4e(l).

Place the desaturated felt in a tared weighing bottle, heat in an oven at 106* to 110* C. (221* to 230" F.) for not less than 1 hour, cool in a desiccator, and weigh. Compute the weight of the moisture-free desaturated felt by the following formula: Weight of desaturated felt in grams x 31.7 _ ^ajgbt in pounds per Area in square indies square feet F-4f. Ash content of moisture-free desaturated felt,--Incinerate 10 grams of desaturated felt as obtained in paragraph F-4e(l) to constant weight in a weighed crucible in a muffle furnace or over on open flame at a temperature of not less than 800* C. Cool in a desiccator, weigh, ana compute the percentage ash in the- de salinated felt. F-ig. Thickness of moisture-free desaturated felt,--Determine the thickness of the desaturated felt as obtained in F-4e(l) at not less than 10 points equally spaced along the strip by any ac ceptable method. Report the-average of these readings, F-4h. Saturation of felt.--Cut three strips 2 inches wide and 8 inches long at random from the sheet and warm in, an oven at abont 80* C. (176* F.) until the coating asphalt can be easily stripped from the saturated felt. In removing the coating asphalt care should' be taken to remove as little felt as possible and that none of the coating asphalt remains on tiie felt. Weigh tile coat ing-free felt and extract with benzol (carbon tetrachloride, chloro form or carbbn bisulfide' will usually give the same results,' but benzol should be used'in case of dispute) in a suitable extraction . apparatus until the solvent runs through colorless.
