What is BS EN 62718 - D.C. supplied electronic ballasts for lighting fluorescent lamps about ?
BS EN 62718 is a European standard on the rolling stock that discusses D.C. supplied electronic ballasts for lighting fluorescent lamps to standardize the performance of lighting fluorescent lamps.
BS EN 62718 outlines the performance and constructional requirements, and associated tests, for D.C. supplied electronic ballasts used to supply fluorescent lamps for lighting on railway rolling stock.
Its requirements replace those of IEC 61347 for all railway rolling stock applications and specify and complete those of IEC 61347 for the specific needs of railway rolling stock applications.
BS EN 62718 applies to electronic ballasts:
- Supplying pre-heated cathode fluorescent lamps without integrated starters, tubular or single capped, according to IEC 60081 and IEC 60901 respectively
- Having a single and non-adjustable luminous flux level
Note: BS EN 62718 does not apply to electronic ballasts supplying non-pre-heated cathode lamps and/or lamps with integrated starters.
Who is BS EN 62718 - D.C. supplied electronic ballasts for lighting fluorescent lamps for ?
BS EN 62718 on D.C. supplied electronic ballasts for lighting fluorescent lamps is useful for:
- Pre-heated cathode fluorescent lamps and fluorescent lamps manufacturers
- Test centres
- Regulatory authorities
Why should you use BS EN 62718 - D.C. supplied electronic ballasts for lighting fluorescent lamps ?
In a fluorescent lighting system, the ballast regulates the current to the lamps and provides sufficient voltage to start the lamps. Without a ballast, a fluorescent lamp connected directly to a high voltage power source would rapidly and uncontrollably increase its current draw.
BS EN 62718 guideline assists you with characteristics, product information, normal service conditions, constructional requirements, performance requirements, exceptional conditions of use, and safety requirements for D.C. supplied electronic ballasts for lighting fluorescent lamps used in railways.
BS EN 62718 also guides test conditions, environmental conditions, other conditions, routine tests, type tests, investigatory tests, verification of construction, and performance requirements for D.C. supplied electronic ballasts for lighting fluorescent lamps used in railways.
With compliance and obedience to BS EN 62718, you can meet minimum constructional requirements and standardize the performance of D.C. supplied electronic ballasts for lighting fluorescent lamps.
