Determination of accessible parts of IEC 62368 V.1 Accessible parts of equipment V.1.1 General An accessible part of an equipment is a part that can be touched by a body part. For the purposes of determining an accessible part, a body part is represented by one or more of the specified test probes. Accessible parts of an equipment can include parts behind a door, panel, removable cover, etc. that ...
LM-82 is a standard for the reliability testing of LED test instruments released by the American Lighting Engineering Society (IES). This standard specifies a series of test methods to help evaluate the performance and reliability of LED lighting products. LM-82 standard LM-82 Standard Overview The LM-82 is a standard for testing the reliability of LED lighting products. It aims to provide a stand...
Introduction The assessment and characterization of lighting systems relies heavily on goniophotometric data. But there are difficulties along the way. There are a number of variables, both technological and environmental, that may affect the precision and dependability of goniophotometric readings. In this piece, we’ll look at some of the most frequent problems with goniophotometry and talk...
Introduction Electronics are very important to a variety of marine pursuits, including navigation, communication, propulsion, and a variety of other on-board operations. However, the sea environment has its own unique challenges when it comes to electromagnetic compatibility (EMC). Electromagnetic interference, often known as EMI, poses a risk to the equipment on board a ship since it may be broug...
Portable fans and window fans Other than as described in 9.2.2, a moving part that causes a risk of injury to persons shall be guarded or enclosed. A moving part such as a rotating grille, rotating air deflector driven by an airstream, or an impeller is not required to be guarded when the moving part complies with all of the following applicable requirements: a) When motor driven, the impeller: 1)...
Assembly Security Test A flush receptacle having a 5-15R,5-20R,6-15R, or 6-20R configuration is to be mounted in the test fixture described in Figure 124.1, and 50 lbf (220 N) is to be applied, as shown in Figure 124.2, for a period of 10 s by means of a push-out tool inserted into the slots of the receptacle. The push-out tool required for configuration 5-15R is to be as shown in Figure 124.3. Re...
Introduction Electronic components are often put through their paces in today’s fast-paced technological world, where they are exposed to a wide range of environmental conditions that might have an effect on their performance and dependability. Vibration is one such phenomenon that may result from anything from traveling to operating machines. Manufacturers and researchers use environmental ...
Introduction Vehicles’ resistance to wear and tear, security, and efficiency are all negatively impacted by corrosion, making it a major problem for the auto industry. Due to the wide range of environments to which automotive parts are subjected, comprehensive corrosion testing is essential before they can be relied upon. Corrosion resistance of automotive materials and coatings may be deter...
Lighting is an indispensable part of human life. It can not only provide light, but also has an important role in shaping the environment, improving work efficiency, and promoting human health. In order to ensure that the quality and performance of lighting products meet international standards, Lighting Research Center has formulated a series of lighting standards, including the LM-82 standard. T...
