In 2026, the Bureau of Indian Standards (BIS) completed and issued the revised standard IS 16102-2:2026 for the operational performance of outdoor LED lighting equipment. As a core mandatory standard for India’s outdoor LED lighting sector, this update further refines technical requirements and improves test specifications on the original basis. It aims to enhance the reliability, safety, and ad...
On February 24, 2026, the Bureau of Indian Standards (BIS) officially released the revised safety standard for self-ballasted LED lamps for general lighting, IS 16102-1:2026, which replaces the 2012 version. It specifies that the transition period for the old and new standards will last until August 2, 2026, after which the old standard will be formally abolished. As the core mandatory safety stan...
Abstract: Electromagnetic Interference (EMI) is a core factor restricting the electromagnetic compatibility (EMC) of electrical and electronic products. As a key part of product compliance certification and quality control, EMI test can accurately quantify conducted and radiated interference generated by equipment during operation. Taking LISUN EMI-9KB Conducted and Radiated Interference Test Sys...
Abstract: Electromagnetic interference (EMI) is a key factor restricting the electromagnetic compatibility (EMC) of electrical and electronic products. Quantitative measurement of conducted interference and radiated interference is critical for product compliance, market access, and performance optimization. This paper takes the LISUN EMI‑9K series EMI Receiver as the research object, systemati...
Abstract EMC instruments form the core toolkit for verifying the electromagnetic compatibility (EMC) of electrical and electronic products. Their fundamental task is to precisely measure and evaluate the levels of electromagnetic interference (EMI) generated by equipment, ensuring it does not cause interference to other devices or the environment and possesses a certain degree of immunity. This a...
The main measurement device in conducted and radiated emission tests is an EMI test receiver. Antennas LISNs and test sites get significant coverage but the receiver arrangement ultimately defines the distinction between measured values of true emissions or artifacts of set-up and signal processing. In pure EMC testing facilities there is a tendency to separate limits by a few decibels. Virtually,...
A Line impedance stabilization network is an underlying piece of conducted EMI testing since it establishes a known and reproducible electrical environment between equipment under test and a power source. No such controlled interface results in varying emission results when supply impedance cable routing and background noise are not controlled making comparisons meaningless. The LISN matches the i...
EMC compliance testing is used to confirm that an electrical or electronic device does not emit objectionable electromagnetic disturbances or does not excessive become susceptible to causes of electromagnetic disturbances in its natural habitat. The principle of its working is based on coexistence. Various equipment should be able to share the electrical infrastructure and spectrum without interfe...
Instrumentation alone does not give an accurate EMI EMC measurement. It is the sum total of a well-adjusted arrangement with the electromagnetic environment working jointly with the test configuration and operator discipline. Minor differences in grounding cable routing or placing equipment can change the results by several decibels that is usually the difference separating a pass and a failure. E...
EMI-9KB is popularly utilized in compliance and pre compliance laboratories to obtain fine EMI testing, and a repeatability and stability of testing is of utmost significance. In radiated and conducted measurements of small perturbations across the electromagnetic environment can cause a shift of results by multiple decibels. These variations are not in any way related to the equipment being teste...
EMC conducted emissions testing is one of the starting activities in the contemporary compliance and product development laboratories. It measures unwanted radio frequency energy that travels on line of power and signal instead of traveling through free space. Practically, EMI test of conducted phenomena involves identifying whether a device emits a back injection into the mains or other linked ca...
A good and consistent EMC measurement equipment is crucial in a lab doing compliance test and product development. One component of that ecosystem, which is critical, is the LISN which will serve to fix the line impedance and decouple the equipment under test with supply noise. When the routine maintenance is not taken care of, repeatability of measurements is lost, traceability, and safety are ch...
