What is RoHS? RoHS is a legal requirement set forth by EU legislation. It stands for Restriction of Hazardous Substances. This standard has been in effect since July 1, 2006. It is primarily used to control the materials and manufacturing processes of electrical equipment. It is also used in improving human health and environmental protection. The goal of this standard is to eliminate six things f...
As an excellent LED lighting, it will use a variety of test standards for different countries and regional markets. So what kind of measurement methods and test standards should we master for a qualified LED lighting? LED Lamps According to statistics, in most LED production companies, there will be: AC withstand voltage, (or) DC withstand voltage, insulation resistance, ground resistance, electri...
What is a Surge Generator? The SG61000-5 surge generator by LISUN provides a standard platform for testing the resistance of diverse equipment’s power cords and internal connectors to high-energy transient interference induced by natural lightning surge induction and large-capacity load switching. It complies with IEC 61000-4 -5, EN61000-4-5, and GB/T17626.5 requirements The SG61000-5 comp...
Most electronic and other device manufacturers use the IP (Ingress Protection) scale, which ranges from 1 to 8. IPX1 is the lowest level of waterproofing, indicating that the item is not intended to be used in water or when wet. An IPX8 rating indicates that the item can be submerged and still function properly, though the depth and time of submersion vary. An IP rating of 7 is used for most elect...
The determination of the luminous internsity distribution involves the use of a co-ordinate system in order to define the direction in which the intensity measurements are made. The systems used a spherical co-ordinate system with the center coincident with the photometric center of luminaires. From a general point of view the co-ordinate system consists in a group of planes with a single of inter...
How can we classify if an electronic system will disturb our surroundings or not? Independently of any measurement technique, we need a measuring instrument to characterize the disturbances. This instrument is called EMI Receiver. EMI stands for electromagnetic interference. So, an EMI receiver can measure interferences that may disturb an electronic system. EMI Test Receiver On the display of an ...
What Instrument can be used for testing impact of environment on different products? The Salt Spray Test Chamber is a piece of environmental testing equipment that tests the corrosion resistance of products or metal components by replicating salt spray conditions in a controlled setting. The chamber conducts an accelerated corrosion test that involves corroding coated samples to determine their su...
What is ESD Testing? A crackling sweater hair that sticks straight out from your head, a small electric shock from a door handle. We are more familiar with those moments when there is a discharge of static electricity. This phenomenon is known as Electrostatic Discharge or ESD. ESD testing ESD TESTING EQUIPMENT Electrostatic Discharge (ESD) testing is defined as the EMC Tests applied for electrica...
The ESD test is used to determine the durability of electronic devices when electrostatic discharge occurs when a person touches them. These tests can be conducted with the help of lightweight and portable electrostatic discharge simulators, also known as ESD guns. This article will demonstrate how to conduct an ESD test using LISUN’s electrostatic discharge simulator. What is ESD Testing? E...
