9、ization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been establish
10、ed has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
11、 International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Pu
12、blication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such paten
13、t rights. ISO 6594 was prepared by Technical Committee ISO/TC 5, Ferrous metal pipes and metallic fittings, Subcommittee SC 2, Cast iron pipes, fittings and their joints. This second edition cancels and replaces the first edition (ISO 6594:1983), which has been technically revised. ISO 6594:2006(E)
14、ISO 2006 All rights reserved v Introduction The distinctive character of discharge pipelines is that products flow though them in a single direction under the force of gravity; they are thus laid on a slight slope in the direction of flow. As a result, they include descending, vertical, oblique or s
15、lightly sipping components, but exclude any horizontal or ascending components. This International Standard consists of sections covering technical specifications, dimensions, and control and compliance testing. The technical specification applies to cast iron drainage pipes and fittings used for th
16、e discharge of waste water, sewage, rainwater and for ventilation. Thirteen of the nominal sizes used in various countries have been selected. NOTE The nominal size, DN, is a number which permits classification of the pipes and fittings; it is only loosely related to the inside diameter. For the dim
17、ensions and masses, only the most commonly used sizes of the various pipes and fittings were selected. This International Standard does not exclude the use of sizes which may be specified in national standards. If the nominal masses of finished products (pipes, fittings and accessories) are given in
18、 manufacturers catalogues, the lower deviation is not permitted to exceed the value specified in 3.10. The tests and controls provided in the final section are intended to be carried out to check compliance with the requirements given in the other two sections. INTERNATIONAL STANDARD ISO 6594:2006(E
19、) ISO 2006 All rights reserved 1 Cast iron drainage pipes and fittings Spigot series 1 Scope This International Standard specifies the characteristics of cast iron drainage pipes and fittings used for the installation of: discharge pipes for waste and sewage, rain water pipe systems, and ventilation
20、 pipe systems. The technical specification is applicable to the range of nominal sizes, DN: 40 50 70 75 100 125 150 200 250 300 400 500 600. Where applicable, national standards and/or regulations could clarify, and possibly restrict, the field of application of the pipes and fittings covered. In ad
21、dition, this International Standard gives the dimensions for the most commonly used pipe and fitting sizes. It also provides control testing and test methods for checking compliance with the technical specification and the dimensional and other requirements. 2 Normative references The following refe
22、renced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. ISO 185, Grey cast irons Classification 3 Technical specification 3
23、.1 Type of ends and their jointing Cast iron drainage pipes and fittings are of the spigot type without sockets. The pipes and fittings may be assembled using various types of joints whose characteristics and tolerances shall be specified in the national standards or, failing these, in manufacturers
24、 catalogues. In order to achieve satisfactory assembly, each end shall present a free length corresponding at least to the values of Table 1. See Figure 1.

26、 iron used for drainage pipes and fittings shall be at least 150, in accordance with ISO 185, and have a phosphorous content of less than 0,9 %. 3.3 Quality of pipe and fittings Drainage pipes and fittings shall be sound and free from surface and other defects which would impair performance or servi
27、ce life. When fractured, the castings shall show a fine, grey, close and regular grain. Pipes and fittings with small imperfections that are unavoidable due to the manufacturing processes and which are not harmful in any way to their usage shall not be rejected. Drainage pipes and fittings shall be
28、capable of being cut with the tools normally used for installation. ISO 6594:2006(E) ISO 2006 All rights reserved 3 3.4 Marking Drainage pipes and fittings shall carry a durable manufactures mark. The pipes shall carry this manufacturers mark and the indication of the nominal diameter at least once
29、per metre of length. Where possible, the fittings shall have their nominal diameter and, if necessary, the angle of deviation, cast on. The marking shall be effected outside the region of the joint of the spigot (see 3.1). 3.5 Range of nominal sizes The range of nominal sizes is 1) : 40 50 70 75 100
