The flammability of different materials, such as plastics and other materials used in items such as automobile interiors, electronic devices, and electrical appliances, is evaluated using a number of different standards. Some of these standards are FMVSS 302, UL 94, and IEC 60695. Nevertheless, there are a number of important distinctions between these standards: FMVSS 302 is a specialized standard that was designed for the automotive industry to analyze the flammability of materials used in car interiors. Its purpose is to measure the combustibility of these materials. The UL 94 standard is a more comprehensive regulation that assesses the combustibility of a variety of materials, including plastics, and has applications in a number of different sectors. IEC 60695 is a global standard that is used in the process of assessing the potential for electronic and electrical equipment to catch fire. Testing Procedures The flammability of materials is determined using a variety of testing ...

Introduction The rapid evolution of lighting systems, especially with the advent of LEDs, has raised concerns about the photobiological safety of these light sources. IEC TR 62471-2 (2009) is a critical guideline addressing the non-laser optical radiation safety, primarily focusing on the hazards these systems pose to human health, especially the eyes and skin. The standard is widely applicable to assessing non-laser light sources like LEDs and UV radiation in conventional lighting. This article will delve into the application of the blue light tester in evaluating the photobiological safety of lighting systems, with a particular focus on LISUN EN62471-C Optical Radiation Safety Test. Understanding IEC TR 62471-2: Photobiological Hazards IEC TR 62471-2:2009 provides manufacturing guidelines to mitigate the hazards of optical radiation emitted by non-laser light sources. The standard evaluates exposure risks to the eyes and skin, considering factors such as wavelength, exposure time, a...
