EN 16028:2012 (E) 5 Introduction Friction management using solid or fluid (oil, grease, etc.) substances at the wheel-rail interface is a complex subject and includes the following aspects:  lubrication of the wheel flange/rail gauge corner (active interface), commonly referred to as “flange or rail lubrication”;  friction modification of the top of rail/wheel tread interface, commonly referred to as “top of rail friction management”. This European Standard sets out requirements for the lubricant for flange or rail lubrication. It specifies requirements for the lubricant, how to test it and how to approve it. Lubricants should be tested to confirm there is:  compatibility with lubricating systems;  no intolerable increased risk of fire;  no harmful environmental effects;  no incompatibility between the different lubricants in use, particularly between solid and fluid systems;  satisfactory and consistent product quality and performance. The main purpose of the lubricant is to reduce friction and wear, and keep them at an acceptable level. The content is based on current experience and should not exclude developments that can be later incorporated at reissue. SIST EN 16028:2012



EN 16028:2012 (E) 6 1 Scope This European Standard specifies the requirements of lubricants intended for lubrication of the wheel-rail interface between the wheel flange and the rail gauge corner (active interface) applied either directly or indirectly to the wheel flange or to the rail to achieve an acceptable level of friction and wear. It covers the approval procedure, the method of testing and routine control/monitoring of the lubricant. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

The product is designed for direct contact with a rotating wheel flange; the polymeric binder has a sufficiently high melting point such that it does not melt but rather wears when in contact with the wheel flange to ensure dimensional stability. 3.5 batch entire content of a single identified production of lubricant from the same manufacturing process 3.6 active interface contact area between the wheel flange root and the rail gauge side corner Note 1 to entry: For more information on this definition, see EN 15427. 3.7 flange lubrication lubrication of the active interface by applying a lubricant to the wheel flange 3.8 rail lubrication lubrication of the active interface by applying a lubricant to the rail gauge side face 3.9 Lubricant Application Unit (LAU) component of the lubrication system (trainborne or trackside) that delivers lubricant to the active interface Note 1 to entry: This includes spray nozzles, trackside grease distribution units/blades, stick applicators, etc. 3.10 lubrication system components required to apply lubricant to the active interface SIST EN 16028:2012



EN 16028:2012 (E) 10 Note 1 to entry: A lubrication system can include one or more Lubricant Application Units, a reservoir unit, pump and/or a control device. 3.11 trainborne type of lubrication system installed on a train 3.12 trackside type of lubrication system installed on or adjacent to the track 3.13 customer railway undertaking, infrastructure owner, manufacturer or buyer of railway products or subassemblies, or their representative 3.14 supplier supplier of lubricants Note 1 to entry: A supplier might also be the manufacturer of the product. 3.15 product specification document prepared by the customer that describes the conditions and requirements for the lubricant to meet 4 Legislative compliance Where legislation and regulations (European, national or local) concerning ecological and environmental compatibility of lubricants (biodegrability, toxicity, etc.) are applicable, consideration will need to be given to the relevant requirements. The lubricant should be non hazardous and/or non-toxic and should not contain, for example, solvents, lead or any other noxious material. The product should preferably be bio-degradable, as defined in Tables A.1 to A.3. 5 Approval procedure 5.1 General The approval process is undertaken in four stages. Approval given by another customer may be applied during any or all of this approval process. If after any stage the requirements are not met, a decision shall be made to decide whether or not to cease with the approval process. 5.2 Stage 1 – Product specification The product specification shall be fully documented and shall include the following information: a) relevant application data, including equipment types, operating
temperatures, route information etc.; NOTE The typical operating temperature range to take into account is from -25 °C to +80 °C. SIST EN 16028:2012



EN 16028:2012 (E) 11 b) type tests for approval of the lubricant (see Clause 6 and Tables A.1 to A.3); c) additional validation tests (see Table A.4); d) conditions for delivery, packaging and marking (see Clause 9); e) routine tests for production batches (see Clause 8 and Tables A.1 to A.4) and their frequency. Additional requirements may be included such as access to test records, retention of samples, witnessing of tests etc. 5.3 Stage 2 – Presentation of technical data file A file of technical data showing compliance with the requirements in the product specification and the results of type tests and trials shall be presented. A safety data sheet for the product in the language of the interested customer or country shall be included. Refer to European Directive EC1907/2006 (REACH). 5.4 Stage 3 – Validation tests If required by the product specification, the functional characteristics of the lubricant shall be verified by type tests and inspections, usually in a laboratory situation. The results shall be recorded. If required by the product specification, specific, in-service or field trials shall be carried out to verify that the lubricant complies with the requirements in the product specification. The results shall be recorded. For specific tests the lubricant is tested on a specified piece of equipment, usually in the laboratory. Where in-service or field trials are carried out they should be over a time period that will determine the lubricant’s performance in as close to normal service conditions as possible. This should also be over at least a hot and cold season and for a typical range of weather. 5.5 Stage 4 – Decision The approval of the product can be granted by the customer only if all the stages of the procedure and the following are satisfied:  technical documents have been approved;  characteristics conform with the requirements laid down in this European Standard and in the product specification;  functional and in-service trials have been satisfactory. 6 Control and monitoring of product 6.1 Manufacturing process The manufacturing process of the standard production of the lubricant shall be the same as that applied for the product submitted for approval. If the manufacturing process is changed in any way, it shall be documented and the customer shall be notified. NOTE In some cases, this leads to a new approval being required. SIST EN 16028:2012
