ISO/TC 17/SC 15 - Railway rails, rails fasteners, wheels and wheelsets

This document specifies switch and crossing rails that carry railway wheels as specified in ISO 5003. These are used in conjunction with flat bottom (vignole) railway rails. After switch and crossing rails are produced, in order to be ready for railway track use, secondary processing (forging, grinding and heat treatment etc.) is carried out. This document does not include secondary processing. Secondary processing is specified in other standards or through agreements between manufacturer and purchaser. Sixteen pearlitic steel grades are specified, covering a hardness range of 200 HBW to 440 HBW, and include non-heat-treated carbon manganese steels, non-heat-treated alloy steels, heat-treated carbon manganese and heat-treated low

This document specifies the test conditions and the acceptance levels for ultrasonic acceptance tests for the railway rolling stock material, such as tyres, axles and wheels. Unless otherwise agreed, this document is applied when the product standards require mandatory ultrasonic tests or when the ordered optional tests are made mandatory (see ISO 1005-1, ISO 1005-3 and ISO 1005-6).

ISO 5003:2016 specifies the terms and definitions, information to be supplied by the purchaser, tolerances for dimensions, length, technical requirements, inspection rules, identification, certification, and a quality assurance system for as-rolled and heat-treated steel rails for railways. ISO 5003:2016 specifies flat bottom (vignole) railway rails with linear mass of 43 kg/m and above, for conventional and high-speed railway track usage. There are 19 pearlitic steel grades specified, covering a 200 HBW to 400 HBW hardness range and including "non-heat-treated" carbon manganese steels, "non-heat-treated" alloy steels, "heat-treated" carbon manganese, and "heat-treated" low alloy steels.

ISO 6305-2:2007 specifies the quality requirements of the product and the conditions of acceptance testing for rolled non-alloy carbon steel baseplates for use with flat-bottom railway rails.

Specifies requirements (chemical composition, mechanical properties, appearance and soundness, machining allowance and dimensional tolerances, residual imbalance, marking) for the manufacture and supply of rolled, forged or cast solid wheels of unalloyed steels. Also deals with information to be supplied by the purchaser, classification, manufacture, inspection, delivery. Annnex A describes a procedure for shot peening web surfaces of wheels. In addition, the requirements of ISO 404 are applicable.

Specifies requirements (chemical composition, physical and mechanical properties, dimensional characteristics, marking) for the manufacture and supply of rough-rolled tyres of unalloyed steels. Also deals with information to be supplied by the purchaser, classification, inspection, delivery, guarantee. In addition, the requirements of ISO 404 are applicable.

Specifies the dimensional requirements, the surface roughness and, as appropriate, the permissible residual static unbalance for tyres, wheel centres and tyred wheels in the various degrees of finish, and in addition the manufacturing requirements for tyred wheels. For quality requirements for tyres and wheel centres and technical delivery requirements see ISO 1005-1, ISO 1005-4, and ISO 404, respectively.

Specifies the dimensional requirements, the surface roughness and the residual unbalance of forged, rolled or cast solid wheels with curved or straight webs in various degrees or finish. In addition to this requirements, the general technical delivery requirements of ISO 404 apply.

Specifies requirements for the manufacture and supply of rolled or forged wheel centres for tractive and trailing stock, which are suitable for tyring and are made of unalloyed steels in accordance with table 1 and clause 4. Spoked wheel centres are not covered. In addition to this part of ISO 1005, the requirements of ISO 404 are applicable.

Specifies the dimensional requirements and the surface roughnesses. The corresponding requirements of heavy freight vehicle axles or of axles for speeds under 100 kg/h shall be subject to agreement between the purchaser and manufacturer at the time of enquiry and order. In addition to this requirements, the general technical delivery requirements of ISO 404 apply.

Specifies a method and procedure for detection of surface discontinuities. Unless otherwise agreed, ISO 6933 shall be applied when magnetic particle tests are agreed or specified for products such as axles and wheels.

This part of ISO 6305 defines the specifications regarding product quality and the conditions of acceptance for nuts and bolts. Gives manufacturing and acceptance conditions, data to be supplied by the purchaser and packaging. Annexes A to D contain progressive sampling plans.

This part of ISO 6305 specifies the quality requirements of the product and the conditions of acceptance testing for sleepers. When the products are to be manufactured from flat plates, an alternative but equivalent specification may be agreed between the purchaser and the manufacturer. Annex A includes the checking of dimensions and tolerances, annex B shows a check gauge for inclination of the rail seats, and annexes C and D contain progressive sampling plans.

Specifies the requirements for the assembly by press fitting or shrink fitting onto axles of solid wheels, wheel centres and other components. It also specifies the dimensions and tolerances of the completed assembly and the conditions of inspection and supply. Applies to certain types of axles and wheels, to plain or roller axle box bearings and to plain or roller traction motor bearings.

Specifies requirements for the manufacture and supply of axles for tractive and trailing stock of unalloyed and alloyed steels in accordance with table 1 and clause 4. In addition to this part of ISO 1005, the requirements of ISO 404 are applicable.

Contains ultrasonic acceptance testing requirements concerning the materials of axles, wheels and tyres.

This part of ISO 6305 specifies the quality requirements of the product and the conditions of acceptance testing for baseplates. Includes conditions of manufacture, of acceptance testing, and information to be supplied by the purchaser. Annex A includes the checking of dimensions and tolerances. and annexes B and C contain progressive sampling plans.

This part of ISO 6305 specifies the quality requirements of the product and the conditions of acceptance testing for fishplates intended for use with rails of linear mass equal to or greater than 35 kg/m. Annexes A, C and D, respectively include referee gauge for checking height, length and opening, respectively; annex B gives checking method of straightness and annexes E and F contain progressive sampling plans.

Applies to rails with a linear mass of 35 kg/m or more and to special sections used in association with these flat bottom rails. Does not apply, in particular, to grooved rails and check rails. An invitation to tender should normally be accompanied by a definition of the conditions of use and other documents for carrying out the order.
