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 through the glow wire flammability index test and the 850 degree hot wire test. The glow-wire tester is suitable for testing the fire resistance of electrical and electronic products, components, plastic and non-metal insulation parts used in household appliances, such as switch casings, relay sockets, etc., under fault or overload conditions that may cause them to reach high temperatures or ignite nearby parts. The hot wire tester simulates the thermal stress caused by hot elements or resistors such as overload sources or ignition sources in a short period of time, and evaluates the fire hazar...

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 of this International Standard is: – to bring together in one publication object probes and access probes currently specified in other standards, together with any necessary new probes;    – to guide technical committees in the selection of test sphere; – to encourage those concemed to specify test probes in accordance with those already specified in this International Standard rather than modify details and dimensions; – to limit the further proliferation of types of test probe. 1.2 General recommendations When selecting probes, priority should be given to IP code probes. The use of other probes, particul...

In recent years, the growing demand for electromagnetic compatibility (EMC) testing has played a crucial role in the market for EMI/EMC equipment agents. As a supplier of EMI/EMC testing solutions, LISUN has always been dedicated to providing customers with innovative technology and excellent products. This particular EMI/EMC equipment agent is a leader in the industry, with an extensive client network and a stable market share. However, they realized that their product line was lacking an efficient and reliable Three Loop Antenna to meet their customers’ needs in EMI/EMC testing. After conducting comprehensive research and evaluation of different brands and models of antennas on the market, the agent decided to collaborate with LISUN and purchase their VVLA-30M Three Loop Antenna. Unlike previous collaboration cases, this agent highly values LISUN’s reputation as an expert and innovator in the field of EMI/EMC testing. They believe that LISUN can provide them with a high-quality anten...

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 Goniophotometer for LED testing. The LM-79 Type C Goniophotometer working principle : The LM-79 Type C Goniophotometer is mainly used for measuring the photometric performance of lamps and light sources, including the spatial distribution and color measurement of the lamps and light sources in different directions. The spectrophotometric method is used to qualitatively and quantitatively analyze the substance by measuring the absorption of light by the tested material at specific wavelengths or within a certain range of wavelengths. If there is a need to test parameters such as the IES file and the intensi...

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 their normal operation and lifespan. What is a dustproof test chamber: A dustproof test chamber, is used to evaluate the ability of test samples (devices) to resist the penetration of dust particles, the ability to resist abrasion or blockage by sand and gravel, and the ability to store and operate under the effects of dry sand or dust-laden atmosphere. It works by blowing a certain concentration of sand or dust over the surface of the test sample at a certain flow rate, driven by a fan. Working principle of dustproof test chamber: A centrifugal fan is the main energy source for dust movement. ...

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 AS/NZS 3100), a pin that may become alive. Socket-outlets, for use with two-pin flat-in plugs of the type shown in Figure 2.1(b), shall be checked for conformance with this requirement by means of an appropriate test plug having the minimum diameter of face and maximum length of live pins shown in Figure 2(b). Socket-outlets for use with three-pin flat pin plugs of the type shown in Figure 2.1(a) and Figure 2.1(d), and two-pin flat pin plugs of the type shown in Figure 2.1(c) and Figure 2.1(d), shall be checked for conformance with this requirement by means of an appropriate test plug having t...

With the development of technology, LED lighting fixtures have significant advantages in energy efficiency, lifespan, and color temperature. However, at the same time, LED fixtures also have some issues, one of which is EMI. In order to ensure that the EMI of LED fixtures meets the standard requirements, a dedicated instrument called LED fixture EMI Test Machine and EMI Compliance Test Receiver have emerged in the market. EMI is the disturbance (permanent or transient) in an electrical signal caused by sources such as power or magnetic sources. These sources include radiated electromagnetic fields, different voltages, and currents from external sources or devices. Devices are highly sensitive to these effects as they process electrical signals and consume power to operate. EMI interference can decrease circuit performance, increase error rates and data loss, and result in performance interruptions or complete device failure. The range of EMI sources includes other electronic devices, t...
