2、on,the year of last revision.A number in parentheses indicates the year of last reapproval.1.Scope 1.1 This specification covers laminated-wall bituminized fiber drain and sewer pipe for use in the nonpressure conveyance of sewage,industrial waste water,and storm water.NOTE The values stated in SI u
3、nits are to be regarded as the standard.2.Applicable Documents 2.1 ASTM Standard:D2315 Testing Laminated-Wall Bitumin-ized Fiber Pipe2 3.(Materials and Manufacture 3.1 Pipe and Couplings Pipe and cou-plings shall be composed of a multi-ply lami-nated convolute or spiral fibrous structure,with the la
4、minations being adhered with a heat and water-resistant adhesive and then thoroughly impregnated with a bituminous compound.The pipe shall have a smooth interior surface free of obstructiions and rough or flaky areas.Bends,fittings,and adapters shall be of the same material as the pipe,or of a mater
5、ial having equal or better physical and chemical properties.3.2 Fillings Where fittings furnished are of other materials,such as cast iron or steel,they shall conform to any applicable ASTM specifications for such materials.4.Physical and Chemical Requirements 4.1 Pipe and couplings shall meet the p
6、hys-ical requirements prescribed in Table 1.4.2 Joint Tightness Any minor leakage at the joint shall have stopped by the end of a 24-h period.4.3 Longitudinal Permeability Any minor leakage of water from the ends of the pipe shall have stopped after 1 h.4.4 Water Absorption The maximum wa-ter absorp
7、tion shall be 2%of the original weight.4.5 Boiling Water Resistance Specimens shall exhibit not less than 90%of the crush-ing strength prescribed in Table 1.4.6 Heat Resistance The heat shall not cause a weight loss over 1%in the specimen due to exudation of the impregnant.4.7 Chemical Resistance Sp
8、ecimens shall show no visible sign of chemical reaction or deterioration of the impregnant.4.8 Kerosine Resistance Specimens shall meet the crushing strength requirements pre-scribed in Table 1.5.Dimensions 5.1 Pipe and Couplings Dimensions shall conform to those prescribed in Fig.1 and Table 3.5.2
9、Five-Degree Angle Couplings Dimen-sions shall conform to those prescribed in Fig.2 and Table 3.5.3 Bore The bore shall be straight and circular in cross-section as determined by passing a 1-m(40-in.)long mandrel 6.4 mm(At in.)smaller in diameter than the minimum inside diameter of the pipe,freely th
