Static Discharge Gun, is also known as ESD Simulation.With the continuous development of automotive electronic technology, the impact of electrostatic discharge on automotive electronic devices is becoming increasingly significant. This article introduces the phenomenon of electrostatic discharge, analyzes the potential damage it can cause to automotive electronic devices, and proposes an automoti...
As an emerging light source, LED is very different from the traditional light source in terms of its own structure and luminous characteristics. Due to the self -absorption effect of the LED itself and the measurement error brought by the internal shield of the integrating sphere, the LED’s optical flux error is measured with a large amount of optical flux errors. The position and gear scree...
9.3 Stationary fans and permanently connected fans up in UL 507 9.3.1 In accordance with 9.1.1, the design and intended use of a stationary fan or of a fan intended to be permanently connected electrically is to be considered when evaluating an enclosure or guard. 9.3.2 The impeller of a stationary or permanently connected fan shall be constructed so that it cannot be contacted by the probe illust...
The glow-wire tester is used to simulate the ignition of insulation materials or other combustible components inside equipment that may catch fire due to a hot wire or hot element. Under certain conditions, such as fault currents flowing through wires, component overloads, and poor contacts, certain components can reach a certain temperature that causes nearby parts to ignite. This can be tested t...
1 General 1.1 Scope and object This International Standard(IEC61032) specifies details and dimensions of test probes intended to verify the protection provided by enclosures with regard to: – protection of persons against access to hazardous parts inside the enclosure; – protection of the equipment inside the enclosure against ingress of solid foreign objects. SMT IP10T_AL The object o...
Introduction Digital oscilloscopes make it much easier for engineers to gather and display electrical waveforms for analysis, which is a common task for the profession. It is crucial to correctly interpret and analyze waveforms to get a knowledge of the behavior of circuits, which is necessary for solving issues and improving efficiency. This article will take you step-by-step through the process...
LED, as a new type of lighting source, has many advantages such as high efficiency, energy-saving, and long lifespan, gradually replacing traditional lighting sources. However, how can we ensure the light quality and efficiency of LED lights when purchasing them? This requires LED distribution testing and glare rating testing. This article will explore the application of LM-79 Type C Goniophotomet...
Dustproof test chamber is also known as IPX6 dustproof test chamber. With the rapid development of modern technology, electronic products are being widely used in our daily lives. However, due to the delicate circuits and components inside electronic products, they have low tolerance for dust and particles. Therefore, we need to conduct dustproof tests on them during production and use to ensure t...
PREVENTION OF CONTACT WITH LIVE PINS NOTE: Fully recessed socket-outlets that comply with Clause 3.6.4 are deemed to comply with Clauses 3.8.1 and 3.8.2. During normal insertion At any stage during normal insertion of a non-insulated pin plug into a socket-outlet, with the faces of the plug and socket-outlet in parallel planes, it shall not be possible to touch, with the standard test finger (see ...
