1、AMERICAN NATIONAL)HISTANDAROHV ANSI/ASTM D 1861-77 Standard Specification for HOMOGENEOUS BITUMINIZED FIBER DRAIN AND SEWER PIPE1 This Standard is issued under the fixed designation D 1861;the number immediately following the designation indicates the year of original adoption or,in the case of revi
2、sion,the year of last revision.A number in parentheses indicates the year of last reapproval.1.Scope 1.1 This specification covers homogeneous bituminized fiber drain and sewer pipe and fittings for use in nonpressure conductor and drain systems.NOTE The values stated in SI units are to be regarded
3、as the standard.2.Applicable Documents 2.1 ASTM Standards:D2314 Testing Homogeneous Bituminized Fiber Pipe2 3.Materials and Manufacture 3.1 Pipe and couplings shall be composed of an interwoven fibrous structure thoroughly impregnated with a bituminous compound.The wall of the pipe shall be dense an
4、d homogeneous,without seams or laminations,and with a smooth interior surface free from obstructions and rough or flaky areas.Bends and fittings shall be of the same material as the pipe,or of a material having equal or better physical and chemical characteristics.3.2 Pipe and bends shall be provide
5、d with accurately machined or molded tapered joints,and a taper-sleeve coupling shall be provided for each length of pipe and for each bend.The slope of the taper in both pipe and coupling shall be 2 deg(4 deg included angle)(see Fig.1).3.2 All joints for a given size shall be interchangeable and sh
6、all be watertight when properly assembled.4.Chemical and Physical Requirements 4.1 Chemical Resistance The specimen shall show no evidence of chemical reaction or deterioration of impregnant.4.2 Water Absorption The maximum wa-ter absorption shall be 2%of the original weight,calculated to the neares
7、t 0.1%.4.3 Boiling Water Resistance There shall be no evidence of disintegration or separation into laminations after immersion for 6 h,and the crushing strength shall be as specified in Table 2.4.4 Heat Resistance The heat shall not cause a weight loss over 1%in the specimen due to exudation of the
8、 impregnant.4.5 Kerosine Resistance Specimens shall meet the crushing strength requirements spec-ified in Table 2.4.6 Resistance to Flattening The decrease in diameter shall not exceed 3%when tested using loads specified in Table 1.4.7 Crushing Strengths The requirements for dry,wet,and coupling cru
9、shing strength shall be as prescribed in Table 2.4.8 Beam StrengthThe requirements for beam strength shall be as prescribed in Table 2.4.9 Joint Tightness There shall be no evi-dence of the leakage of water at the joint after a period of 24 h.5.Dimensions 5.1 Pipe and CouplingsThe dimensions of the
10、pipe and couplings shall be as specified in Fig.1.1 This specification is under the jurisdiction of ASTM Committee D-8 on Bituminous and Polymeric Materials for Roofing,Waterproofing,and Industrial Uses.Current edition approved Sept.30,1977.Published November 1977.Originally published as D 1861-61 T

12、ction as determined by passing a 1-m(40-in.)long mandrel,7 mm(At in.)smaller in diameter than the nominal diameter of the pipe,freely through the pipe.5.3 Length The standard length shall be 1.5,2.4,or 3 m(5,8,or 10 ft)depending upon the standard practice of the manufac-turer.Length measurements sha
13、ll include the tapered ends of the pipe,and a tolerance of 25 mm(1 in.)shall be allowed.Lengths other than standard shall be increments of 150 mm(6 in.)from standard and unless otherwise specified up to 20%of the short lengths may be supplied in a shipment.No lengths shorter than 1.2 m(4 ft)shall be
14、 furnished with no more than two different short lengths in any one shipment.A coupling shall be supplied with each length of pipe.5.4 Dimensions of Bends Wall thicknesses of bends shall be not less than those of the corresponding pipe.A round ball 7 mm(At in.)smaller in diameter than the nominal si
15、ze shall pass through the bore of the bend freely.Dimensions of the 45 and 90-deg bends of the standard sizes furnished are shown in Fig.2.5.5 Five-Degree Angle Couplings The di-mensions of the 5-deg angle couplings shall be as specified in Fig.3.6.Sampling 6.1 From each lot to be tested or fraction
16、 thereof,representing a product of the same size,select at random a number of lengths equivalent to one half the cube root of the total number of lengths included in the lot,except that in lots of 1000 lengths or less,5 lengths shall be taken.If one half the cube root,as calculated,proves to be a frac-tional number,express it as the next higher whole number.Test specimens shall not in-clude damaged pipe.Tapered joints shall not be included except as specified in Method D 2314.7.Test Methods 7.1
