Overview
UL1581 Wire and cable combustion tester (model YK3261) is a YOUKE brand equipment specially designed to test the flame retardant performance of Wire and cable insulation layers. The tester is designed according to the VW-1 and FT2 combustion test terms in the UL1581-2006 standard, and consists of a test part and a control part. Control system Degree of automation is high, with automatic ignition, temperature calibration functions, temperature and time digital display, stable and reliable use.
Features
1. High anti-corrosion steel plate sealing, lame plating high anti-corrosion paints, no air circulation during the test.
2. The front of the box is equipped with a tempered Glass observation door, which is convenient for observing the test situation.
3. The operation panel is located on the right side of the observation door for easy operation and observation.
4. Interior volume ≥ 4.0m ³, Dimension 2100 * 1360 * 2200mm.
5. Using Thermal Sensor (electrolysis copper 10.0 +/- 0.05g and Thermocouple) and K-type thermocouple, with 0.5mm diameter stainless steel tube jacket.
6. The intelligent PID temperature control meter is matched with the K-type thermocouple, and the reading can reach 1000 ° C.
7. Timer can be set to 0~ 99H99/99M99/99S99, minimum resolution 0.01S.
8. It takes 54s +/- 2s for the test flame to rise from 100 ° C +/- 2 ° C to 700 ° C +/- 3 ° C.
9. Main fixtures include SUS304 #stainless steel test brackets (horizontal and vertical) and combustion blowtorches that meet ASTM D 5025-05.
10. Low-noise industrial fans provide rapid exhaust to ensure the safety of test personnel.
11. PLC Control system and large Touchscreen, beautiful interface, easy to operate.
12. The transmission system is controlled by stepper motor, and the tilt angle can be set, making it accurate and easy to operate.
Principle
The tester applies standard flame to Wire and cable samples through combustion blowtorch to simulate abnormal states such as overheating and overcurrent to test the flame retardant performance of the insulating layer. Control system automatically ignites and adjusts temperature, uses Thermal Sensor and Thermocouple to monitor temperature, Timer accurately records time to ensure that the test process meets the standard requirements.
Applications
Wire and cable insulation flame retardant performance test
Standards
UL1581-2006 Section 1080 (VW-1 combustion test), Section 1100 (horizontal specimen/FT2 combustion test), ASTM D 5025-05
Steps
Prepare methane gas with a purity of at least 98%.
2. Set test parameters, such as temperature and time.
3. Install the specimen on a horizontal or vertical bracket.
4. Activate the automatic ignition and temperature calibration functions.
5. Observe the test process and record the data.
6. After the test, use the fan to exhaust.
Notice
• Make sure the box is sealed and there is no air circulation during the test.
• Use methane gas with a purity of at least 98%, provided by the customer.
Operators should observe through the observation door to avoid direct contact with the gas.
• Regularly check the control components such as Flow rate meter and differential pressure meter.
• Follow the equipment specification parameter settings to ensure the accuracy of the test.
