2. Definitions
2.1 Clay, fire clay, shale, and surface clay are as defined in ASTM Definitions C 43, Terms Relating to Structural Clay Products.1
3. Materials and Manufacture
3.1 Vitrified clay pipe shall be manufac tured from fire clay, shale, surface clay, or a combination of these materials that, when formed into pipe and fired to suitable temper atures, yields a product that is strong, dura ble, serviceable, free of objectionable defects, and conforms to this specification.
4.1.2 The number of specimens to be tested shall not exceed 0.5 % of the number of pipe of each size furnished, except that no less than two specimens shall be tested.
4.1.3 If any of the test specimens fail to meet the requirements, the manufacturer will be allowed a retest on two additional speci mens for each one that failed. The pipe will be acceptable if all the specimens for retest meet the requirement.
4.1.4 If, subsequent to an initial pipe strength failure, the accuracy of the testing machine is questioned, at the request of the manufacturer, the machine may be recali brated and a retest made or a retest may be made upon a machine of known accuracy.
4.2 Absorption: 4.2.1 The absorption of vitrified clay pipe shall not exceed 8 percent. 4.2.2 If any of the test specimens fail to meet the absorption requirements, a retest will be allowed, and the pipe accepted as provided in 4.1.3. 4.3 Hydrostatic Pressure Test: 4.3.1 As an alternative to the absorption test, the manufacturer may, at his option, apply a hydrostatic pressure test to all of the pipes subject to test in each size and run of the pipe. 4.3.2 When the pipe is subjected to an

4.3.3 tf any of the test specimens fail to meet the hydrostatic requirements, a retest will be allowed, and the pipe accepted as provided in 4.1.3.
4.4 Acid Resistance: 4.4.1 This test is used to determine the resistance of pipe to the action of acids en countered in sanitary sewers. The test shall be performed only when specified. 4.4.2 The pipe of each size and shipment shall be acceptable if the acid-soluble matter, from specimens representing such pipe, does not exceed 0.2S %. Failure of any of the specimens to meet the test shall result in the rejection of all the pipe represented by the specimen tested.
5. Sizes and Dimensions
5.1 Sizes and dimensions of pipe are as described in Table 2 (U. S. customary units) and Table 2A (SI units).
5.2 The inside diameter shall not vary from a true circle by more than 3 % of its nominal diameter.
5.3 The average inside diameter shall be determined by taking any two 90-deg (1.6rad) opposing measurements and averaging the readings.
6. Straightness
6.1 Pipe shall not deviate from straight by more than `lit in./ft (5 mm/m) of length when the maximum offset is measured from the concave side of the pipe.
6.2 Measurement shall be taken by placing a straight X-edge on the concave side of the
pipe's full length of the barrel, being sure not to include spigot joint material or socket, and measuring the maximum distance between the straightedge and concave side of the pip
7. Glaze
7.1 Unless otherwise specified, the manu facturer may supply either glazed or unglazed pipe. On glazed pipe, the glaze shall be a continuously uniform layer that is substan tially free of imperfections. Not more than 10 % of the inner surface of any pipe barrel may be free of glaze. There shall be no well defined crazing or hairline cracks.
7.2 Glazing is not required on the outer surface of the pipe at the spigot, for a longi tudinal distance equal to the depth of the socket. Glaze may be entirely absent from the inside of the socket.
7.3 When a ceramic glaze is used, it need only be applied to the inside of the pipe.
8. Blisters
8.1 Pipe of nominal sizes from 3 to 18 in., shall have no blister with a dimension ex ceeding 3 in. (76 mm), and no blister or pimple shall project more than 'It in. (3 mm) above the surface of the pipe.
8.2 Pipe of nominal sizes over 18 in., shall have no blister exceeding 2 in./ft (166 mm/ m) of internal diameter, and no blister or pimple shall project above the surface of the pipe more than 'It in./ft (10 mm/m) of int< nal diameter.
8.3 Pipe Shall have no broken blisters.
9. Fractares and Cracks
9.1 There shall be no fractures or cracks passing through the banel or socket, except that a single crack at the spigot end of the pipe not exceeding 75 % of the depth of the socket, or a single fracture in the socket not exceeding 3 in. (76 mm) around the circum ference nor 2 in. (50 mm) lengthwise may be permitted.
9.2 Chips or fractures on the interior of the pipe shall not exceed 2 in. (50 mm) in length, 1 in. (25 mm) in width, and a depth of one fourth of the thickness of the barrel.
10. Finish of Ends
