What is BS EN 60662 about?
BS EN 60662 is an international standard that includes details for high performance of the sodium vapour lamps.
BS EN 60662 specifies performance requirements for high-pressure sodium vapour lamps for general lighting purposes which comply with the safety requirements of international standards.
BS EN 60662 gives technical specifications such as terms and definitions, general lamp requirements, marking, dimensions, caps, test requirements for lamp starting, warm-up, electrical and photometric characteristics, information for ballast and ignitor design, information for luminaire design, maximum lamp outlines, the numbering system for lamp data sheets, etc for high-pressure sodium vapour lamps.
Who is BS EN 60662 for?
BS EN 60662 on high-pressure sodium vapour lamps is for:
- High-pressure sodium vapour lamps manufacturers
- High-pressure sodium vapour lamps suppliers and dealers
Why should you use BS EN 60662?
High-pressure sodium vapour lamps are considered as most energy-efficient lamps among all artificial light sources. It has a very long lifespan that goes up to 50000 hours.
BS EN 60662 on a high-pressure sodium lamp helps you in designing the HPS lamp so that its performance is reliable in normal and is in accepted use, just by satisfying the given requirements.
The performance specifications mentioned in BS EN 60662 on a high-pressure sodium lamp, enhance their efficiency and durability, making them ideal for use at airports, seaports, streets, railway marshalling yards and crossings etc.
What’s changed since the last update?
BS EN 60662:2012+A11:2019 supersedes BS EN 60662:2012, which is withdrawn.
Following amendments are made in BS EN 60662:2012+A11:2019:
- Introduction of a test device for ignition, restriction to performance requirements. Safety requirements are given in IEC 62035: Discharge lamps (excluding fluorescent lamps) – Safety specifications
- Split of the lamp data sheets which make use of the test device and for those which don’t
- Provisions for measurement during starting, measurement of electrical and photometrical characteristics and tests for lumen maintenance and life
- General review e. g. of maximum lamp outlines and alignment of data, new order of datasheets by wattage
