1. Standard-- DIN 5510-2:2009-05 fire test for railway component
DIN 5510-2: preventive fire protect in railway vehicle parts 2: Fire behaviour and fireside effects of material and parts

Effective Date:
This standard since May 1, 2009 entered into force

Introduction Date:
Since May 1, 2012, the May 1, 2009 after the development of the vehicle must follow the standards.

Transition period:
Latest from 1 May 2014, the remains can only supply to meet the standards of vehicles.

2. Standard Scope -- DIN 5510-2:2009-05 fire test for railway component
This standard applies to vehicle, these vehicles including railway construction and operation of the provisions of (EBO), narrow-gauge railway construction and operating requirements (ESBO), magnetic levitation railway construction and operation of the provisions of (MbBO) and the tram construction and operation requirements (BOSstrab) The effective range. This standard has provided the following objectives:
- The phenomenon of combustion characteristics and burn complicated classification
- Have the necessary test methods
- To prevent fire, on the manufacture of vehicles, materials and components used in the combustion characteristics and burn complicated by the phenomenon of necessary requirements.

3. Standard Brief- DIN 5510-2:2009-05 fire test for railway component
DIN 5510-2 determination the fire classification of railway vehicle material and structure by burning buhaviour, smoke density, dropping behaviour and toxic.
