Indian Standard SPECIFICATION FOR
CRANE RAIL SECTIONS
IS : 3443 - 1989
( First Revision)
O.FOREWORD
0.1 This Indian Standard (First Revision) was adopted by the Indian Standards Institution on 4 June 1980, after the draft finalized by the Struc- tural Sections Sectional Committee had been approved by the Structural and Metals Division Council.
0.2 This standard was first published in 1966. In this revision the range of rail sizes has been enlarged to include some of the sections commonly used in the industry.
0.3 -4 supplementary list of rail sections covering the 125 kg/m rail (earlier designated as CR 140) a few non-metric railway rails and some non-metric and metric crane rails which are in regular use is given in Appendix A.
0.4 In the formulation of this standard assistance has been derived from: IRS-T1264 Flat bottom railway rails, Ministry of Railways, Govern-
ment of India.
GOST 4121-76 Crane rails gosudlrstvennyj’ komitet standartov, h;leri Izmeritel’nyh Priborov SSSR (USSR).
0.5 For the purpose of deciding whether a particular requirement of this standard is complied with, the final value, observed or calculated, expressing the result of a test or analysis, shall be rounded off in accordance with IS : 2-1960*. The number of significant places retained in the rounded off value should be the same as that of the specified value in this standard.
1. SCOPE
1.1 This standard lays down the dimensions, shape and other requirements of crane rail sections.
*Rules for rounding off numerical values (rcviscd).

IS : 3443 - 1980
2. GENERAL RE QJJIREMENTS FOR THE SUPPLY OF MATERIAL
2.1 General rcquiremcntn rclnting to supply of material shall be as laid down in IS : 1357-1967*.
3. DESIGNATION
3.1 (:rane rail sections conforming to this sta.ndard shall be designated by the Ictters ISGK followed by the head wiclth of the rarl section in mtllimctres. PIowevcr, the crane rail sections covcrcd in i\ppcndix ;2 shall he designated by the \vright in kg/m.
3.2 For shop marking and drawing oflice purposes, abbreviated reference symbol GR instead of ISCR may be permitted provided specific under- standing exists between the producer, drawing office and fabricator.
4. CHEMICAL COMPOSITION
4.1 The material when analysed in accordance, with the appropriate part of IS : 228t and its relevant parts, shall have any of the chemical compositions on the finished product given in Table 1. The location of sample for chemical analysis shall be as shown in Fig. 1.

5. TENSILE PROPERTIES
5.1 The tensile test specimen shall be located as shown in Fig. 1 when tested in accordance with IS : 1608-1972:, the steel shall have a minimum tensile strength of 710 MPa (72 kgf/ mm2), with a minimum elongation of 14 percent on a gauge length of 5*652/%where So is the area of cross section of the specimen in the gauge length.
*General requirements for the supply of metallurgical materials (jirsf reuision). tMethods of chemical analysis of steels (second revision being issued in parts). ZMethcds for tensile testing of steel products (Jirst revision).

6. HARDNESS
6.1 The hardness of the rail head when tested in accordance with IS : 1500- 1968* shall be not less than 200 HB.
7. SAMPLING
7.1 The number of samples to be tested for chemical analysis, tensile pro- perties and hardness shall bc one for every 100 tonnes or part thereofsubject to a minimum of ‘one specimen per cast.
8. DIMENSIONS, TOLERANCES AND SECTIONAL PROPERTIES
8.1 The dimensions of crane rail sections shall be as given in Table 2. Clalculated sectional properties based on these dimensions are given in Table 3.
8.2 The tolerances on various dimensions of crane rail sections shall be as given in Table 4.
8.3 The dimensions of some of the rail sections commonly used in the country are covered in Appendix A along with relevant tolerances and sectional properties.
*Method for Brine11 hardness test for steel (jirsf rtz~ision).

10.1.1 The material may also be marked with the IS1 Certification Mark.
Nore - The use of the ISI Certification Mark is governed by the provisions of thf Indian Standards Institution (Certification Marks) Act and the Rules and Regulation< made thereunder. The ISI M&k on products covered by an Indian Standard conveys the assurance that they have been produced to comply with the requirements of that standard under a well-defined system of inspection, testing and quality control which is devised and supervised by IS[ and operated by the producer. ISI marked products are
also continuously checked by 1Si for conformity to that standard as a further safeguard. Details oFconditions under which a licence for the use of the IS1 Certification Mark may be granted to manufacturers or processors, may be obtained from the Indian Standards Institution.
