BS6853 Flame Retardant Test for Electronic Products
BS6853 Flame Retardant Test for Motorcycle Electronic Products - Standard Name:
BS 6853: General specification for fire protection in the design and construction of passenger trains
BS 6853: Code of practice for fire precautions in the design and construction of passenger carrying trains.
According to the requirements of BS6853, the design and installation of electronic products for rail vehicles (locomotives) should consider:
-Electrical protection
When dealing with leakage and clearance distances, special attention should be paid to the tendency of the material to track, and the voltage used, whether AC or DC, in order to minimize the occurrence of circuit failures. Appropriate electrical protection should be taken to ensure that in the event of a fault, the rate of energy leakage and the duration of the fault are minimized. This recommendation applies to electricity both as a source of combustion and to dangerous leakage electricity in the event of an arc.
-Prevent arcing
Suitable arc shields should be used to protect the passenger compartment. Particular attention should be paid to areas where the fault is not electrically protected, excluding the protection of the substation by circuit breakers.
-Prevent high current circuit breaker output
Appropriate protective covers should be used to prevent vehicle circuit breakers from leaking and becoming a source of ignition for materials or debris, as well as to prevent aging of other systems, which, if they malfunction, would increase the risk of fire.
-Prevent sparks from current collectors
Suitable protective covers should be used to prevent the incandescent particles of the current collector from becoming a source of ignition for underbody materials and debris.
