What is glow wire test apparatus?

The glow wire test equipment is a device that is used to assess the capability of electrical and electronic components to endure circumstances of high heat, fire, and temperature. The test is carried out by first heating a thin wire, which is often made of nichrome, to a temperature that has been predetermined, and then putting the heated wire into contact with the component that is being evaluated. The glow wire test is used to replicate the effects of high temperatures on the component, such as those that are created by a fire, and to assess the component's capacity to continue operating and to prevent the spread of fire. The test is called a glow wire test.

In most cases, the equipment for the glow wire test will include a heating element, a control system, and a fixture that is used to hold the component that is being evaluated. The heating element is typically a wire made of nichrome, and it is heated to a predetermined temperature by an electrical current. The control system is responsible for regulating the temperature of the heating element and making certain that the test conditions are kept within the prescribed boundaries at all times. During the course of the test, the component will be held in position by the fixture, which also guarantees that the heating element will make contact with the component in the appropriate spot.

The glow wire test is carried out in accordance with a number of international standards, such as IEC 60695-2-12 or UL 746A. These standards detail the conditions of the test, which include the temperature of the heating element, the length of time that the test is conducted, and the location of the heating element on the component. The results of the tests are used in order to ascertain the component's ability to withstand the effects of fire and to place it into a certain protection category, such as IPXXD.

In conclusion, the glow wire test apparatus is a piece of equipment that is used in the process of determining the degree to which electrical and electronic components are resistant to fire. The component is put through a test that involves mimicking the effects of high temperatures on it by putting a nichrome wire that has been heated to a certain degree into contact with it. The purpose of the test is to determine how well the component can stop the spread of fire. The examination is carried out in accordance with the international standards, and the outcomes are used in the process of assigning the component to a certain protection category.

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...
