IS 16106:2012 Standard was adopted by the Bureau of Indian Standards, after the draft finalized by the Electric Lamps and Their Auxiliaries Sectional Committee had been approved by the Electrotechnical Division Council.
IS 16106:2012 standard has been developed for the electrical and photometric measurements of solid state lighting (SSL) products commonly known as LED. While many other standards for photometric measurements of light sources and luminaires are available, these standards are separated for measurement of lamps of luminaires with LED as the light source. Since the current SSL products are in the forms of luminaires or lamps, and LED light sources in the luminaires are not easily separated as replaceable lamps these existing standards cannot be applied directly to SSL products. This necessitates the use of absolute photometry. The Annex A in this standard provides the description of how absolute photometry varies from relative photometry, which have historically been the lighting industry standards. Thus, this standard provides test methods addressing the requirements for measurement of SSL products. Since SSL technologies are still at their early stages, requirements for measurement conditions and appropriate measurement techniques may be subject to change at any time as the SSL technologies advance.
IS 16106:2012 standard is based on IES-LM-79-2008‘IES approved method for the electrical and photometric measurements of solid state lighting products’, issued by the Illuminating Engineering Society of North America. Reference given to other standards have been changed to corresponding Indian Standards.
For the purpose of deciding whether a particular requirement of this standard is complied with, the final value, observed or calculated expressing the result of a test or analysis, shall be rounded off in accordance with IS 2: 1960 ‘Rules for rounding off numerical values (revised)’. The number of significant places retained in the rounded off value should be the same as that of the specified value in this standard IS 16106:2012.
