Electric Wire and Cable Burning Tester: Efficient Tool for Assessing Cable Non-Propagation of Flames
The electric wire and cable burning tester is a precision instrument specifically designed to determine the non-propagation of flames of cables under fire conditions. This equipment is suitable for various cable types including single plastic wires, control cables, cross-linked cables, elevator cables, ship cables, and mining cables. Additionally, it can conduct vertical burning tests for high self-extinguishing low smoke halogen-free flame-retardant polyolefin insulation materials and 105°C low smoke halogen-free flame-retardant irradiated polyolefin insulation materials.
The design of the electric wire and cable burning tester adheres to the following national standards:
• GBT 18380.11-2008 “Tests on electric cables and optical cables under fire conditions – Part 11: Test for vertical flame propagation for a single insulated wire or cable – Apparatus”
• GBT 18380.12-2008 “Tests on electric cables and optical cables under fire conditions – Part 12: Test for vertical flame propagation for a single insulated wire or cable – 1 kW pre-mixed flame test method”
Furthermore, this equipment is effectively compliant with the international standard IEC 60332-1/2, ensuring international applicability and accuracy of test results.
RSB-WC Wire Cable Flame Tester
Key Features
• Automatic Ignition: Utilizes a high-voltage igniter for automatic ignition, ensuring ease of operation.
Corrosion Resistance Design: Designed with a structure resistant to smoke corrosion, enhancing longevity.
• High-Quality Components: Critical components are imported to ensure stability and reliability of the equipment.
• Digital Display and Automatic Control: Equipped with digital display timing functions, the test procedure is fully automated for convenient operation.
Operating Principle
The electric wire and cable burning tester employs a control circuit to manage the application time of the flame and operational procedures. The device provides a flaming combustion source to ensure the accuracy and repeatability of tests.
Applications
The vertical burning tester for electric wires and cables finds wide application in the cable manufacturing industry, construction industry, and quality inspection organizations. Through vertical burning tests, it effectively assesses the safety performance of electric wires and cables under emergency conditions, providing essential guidelines for design, production, and usage. Moreover, this equipment is used for researching new flame-retardant materials, developing high-performance electric wire and cable products, and establishing relevant industry standards. Continual optimization and improvement of testing methods by the vertical burning tester contribute to enhancing the safety performance of electric wires and cables, reducing fire risks, and safeguarding life and property.
Testing Procedure
• Preparation: Ensure a safe test environment free of flammable materials and check the burning tester for integrity. Prepare the cable samples by cutting them to specified lengths and diameters.
• Sample Installation: Secure the cable samples on the fixture of the burning tester in a vertical position. Adjust the burner position to a certain height above the cable.
• Start the Test: Ignite the burner to initiate the cable burning. Observe and record parameters such as burning time, burning length, smoke density, etc. Maintain a safe distance during the test to avoid injury from sparks.
• End the Test: Once the cable has burned completely or reached the predetermined time, turn off the burner and allow the sample to cool. Compile test data for analysis and evaluation of the cable’s burning performance.
This systematic approach ensures thorough assessment of electric wire and cable fire safety characteristics, contributing to enhanced product reliability and safety in various applications.

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...
