16、 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 established has the right to be represented on that committee. Int

17、ernational 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. International Standards are drafted in accordance with t

18、he 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. Publication as an International Standard requires approval

19、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 patent rights. ISO 6594 was prepared by Technical Committee IS

20、O/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. SANS 6594:2008This s tandard may only be used and printed by approved subs

21、cription and freemailing clients of the SABS .ISO 6594:2006(E) ISO 2006 All rights reserved vIntroduction 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

22、. As a result, they include descending, vertical, oblique or slightly 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 specificatio

23、n applies to cast iron drainage pipes and fittings used for the 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;

24、it is only loosely related to the inside diameter. For the dimensions 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 fi

25、nished products (pipes, fittings and accessories) are given in 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

26、the other two sections.

27、(E) ISO 2006 All rights reserved 1Cast 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 ventilatio

28、n 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 a

29、ddition, 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 ref

30、erenced 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

31、3.1 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 manufacturer

32、s 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.

35、ge pipes and fittings shall be sound and free from surface and other defects which would impair performance or service 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 proces

36、ses and which are not harmful in any way to their usage shall not be rejected. Drainage pipes and fittings shall be capable of being cut with the tools normally used for installation.

The pipes shall carry this manufacturers mark and the indication of the nominal diameter at least once per metre of length. Where possible, the fittings shall have thei

38、r 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 75 100 125 150 200 250 300 400 500 600 3.6 External diameters and tolera
