What are the principles of LISUN glow wire tester?

 

The LISUN glow wire tester is a device that simulates real-life situations in which a product might catch fire in order to determine how likely it is that an electrical or electronic piece of equipment would catch fire in the event of an accident. The LISUN glow wire tester operates according to the following guiding principles:

  • Measurement of temperature: This glow wire tester makes use of a thermocouple, which is brought into direct contact with the wire in order to get an accurate reading of the wire's temperature.
  • Ignition source: the wire is heated by an electrical current, and once it reaches a particular temperature, it will ignite, mimicking a fire danger. Once it reaches this temperature, the wire will ignite.
  • Preparing the Specimen: The specimen for testing is prepared by securing it to the testing apparatus in a manner that replicates the circumstances that would be present in actual use.
  • Test technique: The testing procedure consists of heating the wire to a certain temperature and maintaining that temperature for a predetermined period of time. During the course of the test, the behavior of the test specimen is monitored, and notes are taken of any igniting or flaring that occurs.
  • The findings of the test are analyzed and interpreted in a manner that takes into account both the kind of specimen that was used and the standard that was used. It is determined to be safe for handling if the specimen does not catch fire or ignite.
  • Repeatability refers to the need that the testing method be carried out several times using the same test specimen and under the same environmental circumstances in order to guarantee accurate and reliable findings.
  • The LISUN glow wire tester has a number of safety measures, including an alert and an automatic shut-off mechanism, to guarantee that the testing operation is carried out in a manner that is risk-free and reliable.

In conclusion, the LISUN glow wire tester is an effective instrument for determining whether or not a piece of electrical or electronic equipment poses a risk of starting a fire. It contributes to the guarantee of the goods' safety and offers useful information for the enhancement of the items themselves.

What are the differences of FMVSS 302, UL94 and IEC60695 for flammability test?

Image
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 ...

125 Grounding Contact Test 125.1 Grounding receptacles having a 5-15R,5-20R，6-13R，6-20R，7-15R，14-15Ror 15-15R configuration are to be subjected to the tests in this section. 125.2 Previously untested devices are to be used. Each device is to be mounted in a flush device box, or as otherwise intended, with its face in a vertical plane. A nonmetallic faceplate is to be installed if intended. A solid 14 AWG (2.1 mm2) copper conductor is to be connected to the receptacle grounding terminal. GNGPL SB1610_AL 125.3 With the receptacle oriented to create the maximum contact displacement (possible distortion of contact affecting its contact ability), the test pin A. Figure 125.1 is to be fully inserted in the grounding contact. A 5 lb (2.27 kg) weight is to be gradually suspended form the test pin 6 inches (152 mm) from the face of the receptacle. The weight is to be applied for 1 minute, following which, the weight is to be removed. The application of the weight is to be repeated with the rece...

Accessible parts of equipment with standard IEC 62368 General An accessible part of an equipment is a part that can be touched by a body part. For the purposes of dctermining 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 can be opened without the use of a tool. Accessible parts do not include those that become accessible when floor standing equipment having a mass exceeding 40 kg is tilted. For equipment intended for building-in or rack-mounting, or for subassemblies and the like for incorporation in larger equipment,accessible parts do not include those that are not accessible when the equipment or subassembly is installed according to the method of mounting or installation specified in the installation instructions. A part is considered accessible if the instructions or markings intended to be followed require that a person phys...
