TB/T 2328.5-2008Test Method for Railway Ballast – Part 5: Crushing Rate Test for Ballast Aggregate (English PDF)

Foreword

This Standard non-equivalently adopts EN 13597-2003 "Railway applications - Rubber

suspension components - Rubber diaphragms for pneumatic suspension springs".

Compared with EN 13597-2003, the main differences are as follows.

- ADD requirements and methods for rigidity, height, creep, high and low

temperature tests of auxiliary spring;

- ADD vertical fatigue test requirements and methods of air spring for swing hanger

bogie;

- ADD horizontal fatigue test requirements and methods of air spring for bolster

bogie;

- ADD vertical damping coefficient test methods of air spring with orifice;

- AMEND preparation method of test samples for environment endurance test of air

spring;

- ADD requirements and methods of low temperature air tightness.

This Standard replaces TB/T 2841-2005 "Air spring for railway vehicle". Compared with

TB/T 2841-2005, the main changes are as follows.

- ADD requirements and methods for rigidity, height, creep, high and low

temperature tests of auxiliary spring;

- ADD property parameters requirements of the ultimate pressure withstand

capability of air spring, the maximum physical dimensions, load capacity at

different height; AMEND test methods of main property parameters;

- AMEND items and methods of environment endurance test of air spring.

Annex A of this Standard is informative while Annexes B and C are normative.

Air spring for railway vehicle

1 Scope

This Standard specifies the terms, symbols and coordinate system definition, product

property requirements, inspection test method, inspection rules, marking, packaging,

storage and transportation of air spring for railway vehicle.

This Standard does not describe those components that may influence air spring

properties, such as air supply system of air duct, control valve or auxiliary chamber.

This Standard is applicable to newly-made air spring for railway passenger vehicles

and CRH (China Railway High-speed) vehicles. Air spring for metro vehicles, urban

rail vehicles, mono-rail vehicles, magnetic suspension vehicles and other kinds of rail

vehicles can use this Standard as reference.
