DIN 5510-2 Fire test to cable & Wire used in Railway Vehicle
The definition of the requirements for the burning behavior electrical products and cables for locomotives and cars to cover part of the protection objective 2 (see notes to DIN 5510-1) is geared to the requirements of current VDE-regulations and the current technical condition of railway vehicles.
& Ecosafene Products Service Co.,Ltd have rich experience to provide DIN 5510-2 fire test to cable used in Railway Vehicle
Ä DIN5510-2 Fire test to cable－Standard：
üDIN5510-2 : Preventive fire protection in railway vehicles; Part 2: Fire behaviour and fire side effects of materials and parts, classification, requirement and test methods.
Ä DIN5510-2 Fire test to cable - Scope：
This standard applies to rail vehicles (the cars), which fall within the scope of Railway construction and operation order (EBO), the railway construction and operating rules for narrow gauge railways (ESBO), the maglev construction and operation order (MbBO) and the Regulation on the Construction and operation of the trams (BOStrab) fall.
Ä DIN5510-2 Fire test to cable－Brief：
The requirements for the requirements in terms of flammability, smoke development classes,Dripping and toxicity indicators take the form of allowable exposure lives here risk-based approach to classification of the vehicles on fire protection levels (see DIN 5510-1) and on mounting position of the materials and components in the vehicles (the ceiling area as critical floor area).
Ä DIN5510-2Fire test to cable－Test Method & Requirement：
ü Test method：
- DIN EN 60332-1-2: Burning behaviour of Single Cable
- DIN EN 50266-2-4: Burning behaviour of Bunch Cable
- DIN EN 61034-2: Test for Smoke Density
- DIN EN 50305 9.2: Test for Toxicity

When insulated wires and cables, the test is passed,if the distance between the lower end of the upper mounting and the start of charring more is over 50 mm. The flame expands by more than 540 mm from the bottom of the upper attachment to below, this must be called an error. Shall one failure recorded, two further tests perform. If both tests are passed, then the examination of individual wire or cable as passed.

ü Toxicity test for cable：
The toxicity of the constituent elements of cables and wires will be in accordance with DIN EN 50305 (VDE 0260-305): 2003-03, 9.2, determined. For cable, the evidence the requirements of DIN EN 50264-1 (VDE 0260-264-1) or comply with DIN EN 50306-1 (VDE 0260-306-1) and conform to DIN EN 50305 (VDE 0260-305) tested were described in C.2.3.3 test is not required but can be used alternatively; ie the smoke toxicity of cables can also carry the test according to DIN EN 50266-2-4 (VDE 0482-266-2-4) DIN EN 50266-2-5 or determined (VDE 0482-266-2-5).
