Electronic Ballast Standards
The Indian standards for testing of Electronic Ballast - IS13021 (Part 1 & 2)1991, "AC supplied Electronic Ballasts for tubular fluorescent lamps", was adopted and published by the "Bureau of Indian standards(BIS)" after the draft was finalized by the Electric lamps and their Auxiliaries sectional committee, and the same had been approved by the Electrotechnical division council. IS 13021 Part 1 refers to "General and safety requirements" and IS 13021Part 2 refers to "Performance requirements" of AC supplied Electronic Ballasts for Tubular Fluorescent Lamps (TFL). This is the only Indian standard for testing of Electronic Ballasts for tubular fluorescent lamps. The Indian standards have been prepared by taking assistance from the following IEC documents: • IEC publication 928: 1990 "AC supplied Electronic Ballasts for tubular fluorescent lamps:General and Safety requirements" issued by the International Electrotechnical Commission (IEC). • IEC Doc 34 C (Central office) 173 "AC supplied Electronic Ballasts for tubular fluorescent lamps: Performance requirements". • IEC Pub 555-2 (1982) " Disturbances in supply system caused by household and similar electrical equipment, Part 2: "Harmonics" issued by the International ElectrotechnicalCommission (IEC).

Tubular Fluorescent Lamp (TFL) Standards
Indian Standards for Electronic Ballast (IS 13021 [Part 1 & 2] 1991) refers to AC supplied Electronic Ballasts for operation with Tubular Fluorescent Lamps (TFL) as specified in the Indian Standards for Tubular Fluorescent Lamps{ i.e. IS 2418 (Part 2):1977 "Indian Standard Specification For Tubular Fluorescent Lamps for general lightingservices: Part 2, Standard lamp data sheet (first revision)"}; and for other lamps which are meant for high frequency operation.(i.e. frequencies deviated from the supply line frequency). The aforesaid Indian Standards for Tubular Fluorescent Lamps was adopted by the Indian Standards Institution(ISI) on 27 June 1977, after the draft finalised by the Electric Lamps and Accessories Sectional Committeehas been approved by the Electrotechnical Division Council. This first revision has been undertaken with a view to up-grading many of the essential characteristics of Tubular Fluorescent Lamps and bringing it in line with the revision of the corresponding International Standard, namely, IEC Publication 81 (1974). This was yet again reaffirmed in the year1995.In India, IS 2418 is the one and theonly Indian Standard for Tubular Fluorescent Lamps.

Lamp-Ballast Compatibility
Since the lineage of the Indian Standards for Linear Fluorescent Lamps is directly from corresponding IEC Standards, LFL's made as per the Indian Standards comply with international performance specifications and parameters of global standardization. We have developed our electronic Ballast technology for perfectcompatible operation with these LFL's, and the details of the technical compatibility between these two are detailed at the links "Electronic Ballast Performance Specifications" and explanations given for various test conducted "Electronic Ballast test reports". Due to the parentage of both the Electronic Ballast's Indian standards and the LFL's Indian standards to the corresponding IEC standards,an Electronic Ballast Technology developed as per Indian standards, automatically would be perfectly compatible for operation with LFLs of International Standards too. Note: We chose the 40 W Tubular Fluorescent Lamp-TFL (this 40 W TFL is 4 feet in length and is commonly known as “T12 Fluorescent lamp” in the international market) as the standard reference lamp model for development of our...
