FOREWORD
This Indian Standard ( Third Revision ) was adopted by the Bureau of Indian Standards, after the draft finalized by the Pig Iron and Cast Iron Sectional Committee had been approved by the Metallurgical Engineering Division Council.
The Standard Specification for Cast Iron Fittings for Pressure Pipes for Water, Gas and Sewage was published in 1960 and subsequently revised in 1969 and 1976. While reviewing this standard in the light of developments taken place in India and abroad the Committee deeided to have a separate Indian Standard for short bodied Cast Iron specials meant for Mechanical, Push-on and Flanged fitting which has since been published as IS 13382 : ,1992 Cast iron specials for mechanical and push-on flexible joints for pressure pipe lines for water, gas and sewage.
Since a large number of patterns are available with Indian foundries conforming to the present standard ( IS 1538) the Committee felt to continue the same dimensions and design for fittings suitable for lead joint and flanged joint covered in this standard.
This standard when published will supersede the following Indian standards:
IS 1538
( Part 1 ) : 1976 General requirements
(‘Part 2 ) : 1976 S pecific requirements for sockets and spigots of pipes
( Part 3 ) : 1976 Specific requirements for sockets of fiittings

Indian Standard CAST IRON FITTINGS FOR PRESSURE PIPES FOR
WATER, GAS AND SEWAGE- SPECIFICATION
( Third Revision )
1 SCOPE
1.1 This standard avers the general requirements for casf iron fittings for pressure pipes for water, gas and sewage.
1.2 This standard is applicable to all cast iron fittings having spigots, sockets or flanges as specified in this standard and also to fittings with other type of joints, the general dimensions of which, except those relating to the joints, conform to this standard.
2 REFERENCFS
2.1 The following Indian Standards are necessary adjuncts to this standard :
IS No. 7We
210 : 1978 Grey iron castings ( third revision )
1387 : 1993 General requirements for the supply of metallurgical materials ( second revision )
2078 : 1979 Method for tensile testing of grey cast iron
1500: 1983 Method for Brine11 hardness test for metallic materials ( strcond revision )
11606 : 1986 Method of sampling of cast iron pipes and fittings
4 it SECTION 1 GENERAL REQUIREMENTS
i SIJPPLY OF MATERIAL
3&,Tbe general requirements relating to the supply of the material shall be as laid down in IS 1387 : 1993.
4 MANuFfacruRE
4.1 The metal used for the manufacture of pipes shall be of a quality not less than that specitied for Grade FG 150 of IS 210 : 1978.
4.2 Tbe fittings shall be stripped with all tbe precau- tions necessary to avoid warping or shrinking defects. Tbe fittings shall be free from defects, other than any unavoidable surface imperfections which result from the method of manufacture and which do not affect the use of the fittings. By agreement between the manufac- turer and the purchaser, minor defects may be rectified.
4.3 The fittings shall be such that they could be cut, drilled or machined and may be accepted provided the hardness of the external unmacbined surface does not exceed 210 HBS.
4.4 In tbe case of spigot and socket ends suitable for lead joints, the socket shall be with or without the centring ring.
4.5 In the case of flanged joints, the flanges shall be at right angles to the axis of the joint and machined in face. The bolt boles shall be drilled.
4.6 The bolt bole circle shall be concentric with the bore and bolt boles sh311 be located off the centre lines, unless otherwise specified by the purchaser. Tbe two flanges of the fittings shall be correctly aligned.
5 MECHANICALTESTS
5.0 Mechanical tests shall be carried out during manufacture. Two tests per day of casting may be adequate. The results obtained are taken to represent all the fittings of all sizes made during the day.
5.1 Tests
Two tensile te$ts shall be made on bars cast frqpl the same metal in’accordance with the method specified in IS 2078 : 1979. The results of the tests shall show a minimum tensile strength of 1.50 MPa (N/mm2).
6 BRlNELL HARDNESS TESTS
6.1 For checking the Brine11 hardness specified in 4.3, Brine11 tests shall be carried out on the test bars used for the tats in 5.1. The test shall be carried out by applying either a load of 3 000 kg to a ball of 10 mm diameter for 15 seconds, or a load of 750 kg to a ball of 5 mm diameter for 10 seconds (see IS 1500 : 1983).
7 RETEST
If any piece representing a lot fails in the first instance two additional tests shall be made on test pieces selected from two other fittings from the same lot. If both the test results satisfy the specified requirements, the lot shall be accepted. Should either of these addi- tional test pieces fail, the lot shall be deemed as not complying with this standard.
8 HYDROSTATIC TEST
8.1 For bydrost@ic tests, the fittings shall be kept under
pressure for 15 seconds; they may be struck moderately with a 700 g hammer. They shall withstand the pressure test without showing any leakage, sweating or other defect of any ,kind. The hydrostatic test shall be con- ducted before coating the fittings.
8.1.1 The fittings shall withstand the pressure in Table 1.
8.1.2 When fittings are required for higher test pra- sure, the test pressures are subject to special agreement behveen the purchaser and the manufacturer.

12.3 Unless otherwise agreed between the purchaser and the manufacturer all fittings shall be coated exter- nally and internally with the same material by dipping in a tar or suitable base bath. The fittings may be either preheated before dipping or the bath may be uniformly heated. Alternatively, if mutually agreed behveen the purchaser and the manufacturer, the fittings may be

12.5 Where the coating material has tar or similarbase, it shall be smooth and tenacious and hard enough not to flow when exposed to a temperature of WC but not so brittle at a temperature of 0°C as to chip off when scribed lightly with a penknife.
12.6 When the fittings are to be used for conveying potable water, the inside coating shall not contain any constituent soluble in such water or any ingredient which could impart any taste or odour whatsoever to the potable water after sterilization and suitable wash- ing of the mains.
12.7 In the case of fittings (wholly or partially coated) which are imperfectly coated or where the coating does not set or conform to the required quality specified the coating shall be removed and the fittings re-coated.

( Continuedfom second cover )
This standard differs from the IS0 Recommendation in the following respects:
a) The term ‘fittings’ has been used throughout the specification in preference to the term ‘special castings’,
b) The Brine11 hardness number has been brought down to 210 at the external unmachined surface instead of 215 at the centre of the thickness ( see 4.3 ), and
c) Tolerances on drameters of socket and spigot have been modified.
For the purpose of deciding whether a particular requirement of this standard is complied with, the final values, observed or calculated, expressing the results of a test or analysis, shall be rounded off in accordance with IS 2 : 1960 ‘Rules for rounding off numerical values ( revised)‘. The number of significant places retained in the rounded off value should be the same as that of the specified value in this standard.
