The UL1581 Combustion Tester is specialized equipment designed to perform the combustion test requirements of Underwriters Laboratories (UL) Standard UL1581, Wire, Cable and Flexible Cords.The UL1581 standard covers a wide range of test methods for the combustion performance of wire and cable to ensure the reliability of these products in terms of electrical and fire safety. The tester evaluates the combustion behavior, flame retardancy and fire resistance of wires and cables by simulating actual fire conditions, and is widely used in wire and cable manufacturing, electrical equipment manufacturing, building materials and other industries. The following is a detailed description of the UL1581 Combustion Tester:

I. Main Uses

1. Compliance with standards: for the implementation of the Underwriters Laboratories (UL) standard UL1581 wire, cable and cord combustion test requirements.

2. Combustion performance test: to assess the combustion behavior of wire and cable under specific burning conditions, including burning speed, burning time, flame spread.

3. Flame Retardant Performance Test: Evaluate the flame retardant properties of wire and cable, such as self-extinguishing, drippings, smoke generation, etc..

4. Fire resistance test: Evaluate the fire resistance of wire and cable under the action of high-temperature flames to ensure that it can still maintain power transmission for a certain period of time under fire conditions.

5. Quality Control: Used in the production process of wire and cable for quality control of raw materials and finished products to ensure that the products comply with combustion and flame retardant standards.

6. Certification testing: Used for certification testing of wire and cable products to ensure that they comply with national and industry safety standards.

7. R&D and improvement: In the R&D stage, it is used to evaluate the combustion and flame retardant properties of new materials and cables, and to guide product design and improvement.

II. Working Principle

UL1581 combustion tester by simulating the burning conditions of wires and cables in an actual fire, samples of many types of combustion tests, including vertical combustion test, horizontal combustion test, FT1 combustion test, FT2 combustion test and so on. The specific steps are as follows:

1. Sample preparation: the wire and cable to be tested will be cut and pre-treated according to the standard requirements, and the length and diameter of the sample will be different according to different test methods.

2. Fixing the sample: Fix the sample on the sample holder of the testing machine to ensure that the sample is in the specified position and angle.

3. Ignition: The sample is ignited using a flame of specified size and shape. The ignition time and flame height vary according to the test method. For example, the ignition time for the FT1 combustion test is 15 seconds and the flame height is 125mm.

4. Combustion test:

- Vertical combustion test: fix the sample vertically and ignite the sample with flame to observe the combustion behavior of the sample, including combustion time, flame spreading, drippings, etc.

- Horizontal combustion test: Fix the sample horizontally, ignite the sample with flame and observe the combustion behavior of the sample, including burning speed, burning time, flame spread, etc.

- FT1 Combustion Test: Simulate the burning behavior of wire and cable in a fire to evaluate its flame retardant properties.

- FT2 combustion test: evaluate the fire resistance of wire and cable under the action of high temperature flame.

5. Evaluation of results: According to the standard requirements, the combustion behavior of the sample is evaluated to determine whether it meets the combustion and flame retardant standards. For example, UL1581 standard specifies that the burning speed of the sample should be less than or equal to 100mm/min.

Frequently Asked Questions

Q1What is the scope of application of UL1581 combustion tester?

A1: UL1581 combustion tester is suitable for testing the combustion performance of wires and cables according to UL1581 standard, including vertical combustion (VW-1, FT1), horizontal combustion (FT2), cable combustion test, etc., to evaluate the flame retardant properties and flame propagation ability of wires and cables in a fire.

. The test shall be conducted in a closed exhaust gas treatment system to prevent leakage of harmful gases.

Q2: What are the test specimen size and pretreatment requirements for UL1581 combustion tester?

A2: The length of the test sample is usually 457mm or 610mm, and the number of samples is one strip

. The marking of the flat wire should stick out close to the wide side of the wire. The sample should be pre-treated under standard environment to ensure the accuracy of test results.

Q3: How to control the flame height and burning time of UL1581 combustion tester?

A3: Flame height and burn time are accurately controlled by adjusting the methane flow meter, back pressure gauge and pressure gauge. The methane flow rate should be adjusted to 96530ml/min, the back pressure should be within 12525mm water column, and the pressure should be kept at 69-138kP

. Flame height can be adjusted by manually adjusting the inner and outer flames, or by using a precision flow meter and pressure gauge, usually in the range of 20-200mm. Flame application time can be set from 0-99.99 seconds, with a standard requirement of 15 seconds and an accuracy of 0.01 seconds.

The standard requirement is 15 seconds, and the accuracy can be up to 0.01 seconds. The equipment is equipped with automatic ignition, combustion, stop burning, timing, counting functions, can automatically complete the test process.

It can automatically complete the test process.
