This Standard non-equivalently adopts European standard EN 13913-2003 “Elastic
Basic Components of Rubber Suspension Parts for Railways” and Japanese
industrial standard JIS E 4710-1995 “General Rules on Rubber Vibration Isolators for
Railway Rolling Stock”.
Main differences between this Standard and EN 13913-2003 are as follows.
- Dynamic creep test and test method are not specified;
- Static or dynamic stress relaxation test and test method are not specified.
Main differences between this Standard and JIS E 4710-1995 are as follows.
- Hardness test and test method are not specified;
- Insulation resistance test and test method are not specified.
This Standard replaces TB/T 2843-1997 “General technical specification for elastic
parts for railways” and TB/T 2589-1995 “General Technical Conditions for Rubber
Pads for Electric Locomotives”.
Compared with TB/T 2843-1997 and TB/T 2589-1995, the main changes of this
Standard are as follows.
- Basic performances and requirements of elastic rubber parts are different;
- ADD dynamic performance test of elastic rubber parts;
- ADD static creep test of elastic rubber parts;
- Static performance, adhesive performance, fatigue performance and other
product test methods of elastic rubber parts are different.
Annexes A, B, C, D and E of this Standard are normative.
This Standard was proposed by and shall be under the jurisdiction of Ministry of
Railways Institute of Standards and Metrology.

General Technical Specifications for Elastic
Parts for Railways
1 Scope
This Standard specifies classification, basic performances, requirements, test
methods, inspection rules, marking, packaging, storage and transportation of elastic
rubber parts for railways.
This Standard applies to elastic rubber parts for shock absorption, buffer, flexible
connection, limiting, etc. in hanging system, equipment installation system,
connection, limiting positions, etc. of railways.
This Standard does not apply to air springs, sealed rubber products, coupler buffers,
hoses and conveyor belts of railways.
