This is a Tentative Standard only, published for the purpose of eliciting criticism and suggestions. It is not a Standard of the Society and until its adoption as Standard it is subject to revision. ISSUED, 1917; REVISED, 1922. 1. These specifications cover creosote oil primer for use, when Scope. specified, with coal-tar pitch in damp-proofing and waterproofing below or above ground level, for application to concrete and masonry surfaces. I. SAMPLING. 2. From each shipment or portion thereof representing creosote Sampling. oil of the same kind, a number of packages shall be selected at random equivalent to the cube root of the total number of packages in the lot. If the cube root as calculated proves to be a fractional number, it shall be expressed as the next higher whole number. For convenience, the following table is given, showing the number of samples to be selected for shipments of various sizes: 3. By means of a paddle, the contents of each package selected shall be thoroughly stirred so as to bring all portions thereof into uniform distribution. With an appropriate sampler, not less than 1 pt. of the creosote oil shall be immediately drawn out from the center of each package and transferred to a clean receptacle of suit 1 Criticisms of these Tentative Specifications are solicited and should be directed, preferably before January 1, 1923, to Mr. Prévost Hubbard, Secretary of Committee D-8 on Waterproofing Materials, 25 W. Forty-third St., New York City. Properties. able size, which in turn shall be kept tightly covered, prior and immediately after said samples are being introduced. After all the pint samples have been added, the contents of the container shall be thoroughly agitated, whereupon 1 qt. of the mixture shall immediately be transferred to a clean quart can provided with a tightly fitting screw cap, which shall be immediately fastened in place. This sample shall be considered as representative of the shipment and shall be transmitted to the laboratory for examination, bearing a suitable tag or other means of identification. II. PROPERTIES. 4. The creosote oil primer shall meet the following requirements: ....entirely fluid (b) Consistency at 38° C. (100° F.). Residue, by weight, above 355° C. (671° F.).. not more than 15 (f) Specific gravity at 38°/25° C. (100°/77° F.) of the fraction distilling between 235 and 315° C. (455 and 599° F.)............not less than 1.00 (g) Consistency at 25° C. (77° F.) of the residue..... soft III. METHODS OF TESTING. Methods of 5. The properties enumerated in these specifications shall be determined in accordance with the Standard Methods of Sampling Testing. and Analysis of Creosote Oil (Serial Designation: D 38) of the American Society for Testing Materials.1 11921 Book of A.S.T.M. Standards. TENTATIVE METHODS OF TESTING FELTED AND Serial Designation: D 146-22 T. This is a Tentative Standard only, published for the purpose of eliciting criticism and suggestions. It is not a Standard of the Society and until its adoption as Standard it is subject to revision. ISSUED, 1922. 1. These methods cover the examination of felted or woven Scope. fabrics saturated (but not coated) with asphalt or coal-tar products, for use in the "membrane" system of waterproofing. I. SAMPLING. 2. From each shipment or portion thereof representing a product Sampling. of the same kind, class and weight, a number of rolls shall be selected at random, equivalent to the cube root of the total number of rolls in the lot. If the cube root, as calculated, proves to be a fractional number, it shall be expressed as the next higher whole number. For convenience, the following table is given, showing the number of samples to be selected for shipments of various sizes: II. EXAMINATION OF FINISHED FABRIC. 3. The width of each roll taken shall be measured to the nearest Width. 32 in. The minimum, maximum and average width so obtained shall be reported. 1 Criticisms of these Tentative Methods are solicited and should be directed, preferably before January 1, 1923, to Mr. Prévost Hubbard, Secretary of Committee D-8 on Waterproofing Materials, 25 W. Forty-third St., New York City. Gross Weight per Roll. Wrapping and Net Weight per Roll. Weight per Area per Roll. Detached 4. Each roll taken shall be weighed intact to the nearest 1⁄2 lb. and the minimum, maximum and average gross weight shall be reported. 5. Each roll sampled shall be stripped. All the wrappers and packing material shall be weighed together to the nearest lb. and the average weight shall be reported. Each roll should be temporarily fastened with a piece of light string and handled carefully, so as not to disturb any detached surfacing material. 6. The minimum, maximum and average net weight per roll shall be calculated by subtracting the average weight of the wrapping and packing material as determined in Section 5 from the average gross weight as determined in Section 4. 7. Each roll sampled shall be laid flat, the first convolution or two carefully unwound, and with a knife and straight edge the sheet shall be cleanly cut across at right angles to the edges. A section measuring 30 in. in the direction of the roll's length shall be removed. If the material is surfaced with sand or other fine material any detached particles belonging to each 30-in. section should be retained. The width of each section shall be measured to the nearest in. Each section, together with any detached surfacing, shall be weighed to the nearest gram. The weight in pounds per 100 sq. ft. shall be calculated from the formula: Weight per 100 sq. ft. 1.0582X; Weight of 30-in. section in grams From the results obtained for each roll sampled, the minimum, maximum, and average weight in pounds per 100 sq. ft. shall be calculated. NOTE. As a referee method or in case any dispute arises regarding the weight "per unit area," the method described in Section 8 shall be followed. From the net weight of each roll determined as in Section 6, the weight per unit area may be calculated as a check. 8. The average area per roll in square feet shall be calculated by dividing the average net weight per roll, as determined in Section 6, by the average weight in pounds per 100 sq. ft. as determined in Section 7, and multiplying by 100. NOTE. As a referee method or in case any dispute arises regarding the "area per roll" as calculated, each roll sampled shall be unwound and the total length measured within in. with a steel tape. From the width of each roll, as determined in Section 3, the "area per roll" may be accurately calculated as a check and the minimum, maximum and average for the shipment calculated. 9. If the material is surfaced with sand or other finely comminuted Comminuted material, the surfacing shall be swept with a moderately stiff brush from all the 30-in. sections taken. All the material thus removed shall Surfacing. be caught and weighed to the nearest ounce. From the aggregate areas of all the sections taken, the average weight of detached comminuted surfacing shall be calculated in pounds per 100 sq. ft. 10. The thickness of each specimen shall be measured at 10 Thickness. equally spaced points, 1 in. from a cut edge, with a micrometer gage having flat bearing surfaces at both contact points of not less than in. in diameter and preferably of the spring-and-dial type. The readings for each rolled sample shall be averaged and the minimum, maximum and average thickness calculated to the nearest 0.001 in. 11. From each specimen, 2-in. strips shall be cut as shown at A-1 Moisture. and A-2 in Fig. 1. The 2-in. strips shall be cut into 1-in. squares. About 50 g., selected at random, shall be accurately weighed and distilled with 100 cc. of water-saturated solvent naphtha (crude xylol) in an apparatus of the form and under the conditions prescribed in the Tentative Method of Test for Water in Petroleum Products (Serial |
