GB5455 Precautions for Operating Textile Vertical Combustion Tester

When using the GB5455 Textile Vertical Combustion Tester for testing, it is necessary to strictly follow the operating specifications and safety guidelines to ensure the accuracy of the test results and the safety of personnel and equipment. Specific precautions are as follows:

Preparation precautions before the experiment

The equipment should be placed in a well ventilated laboratory environment without flammable and explosive materials, and should be installed horizontally to avoid affecting the test data due to vibration.

Check if the gas source connection is secure, use gas (such as propane) that meets purity requirements, and confirm that the gas leak detection device is functioning properly to prevent gas leaks from causing safety hazards.

To verify the specifications of the sample, it is necessary to cut the sample according to the requirements of GB5725 standard to ensure that the size and quantity of the sample meet the testing requirements, and to avoid invalid testing due to unqualified samples.

Check the flame height of the igniter, calibrate the flame height to the specified value according to the standard in advance, and ensure consistency in ignition conditions. GB5455 Touch Screen Textile Vertical Combustion Tester (Vertical Flame Retardant Performance Tester) The GB5455 Touch Screen Controlled Textile Vertical Combustion Tester developed and produced by Beijing Xinsheng Zhuorui Technology Co., Ltd. and Xunyu Technology Co., Ltd. is an upgraded product based on the original equipment technology. It adopts touch screen control and has a high degree of test automation. In addition to the original automation functions achieved by various buttons and instruments, the touch screen control model can store past test data and retrieve past data during the test. This device is suitable for various fabrics and their products such as safety nets, protective clothing, and seat belts, and is ultimately applicable to the test method for the combustion performance of vertical textile bottom edges when ignited as specified in the GB5455-2014 standard.

Design standard: GB5455-2014 "Determination of vertical release damage length, smoldering and reigning time of textile combustion performance"

Applicable standard: GB 8965.1-2009; GB6529 ； GB5725； GB/T 6096； GBT13489

Precautions for operation during the experimental process

Operators need to wear protective gloves, goggles, and other protective equipment to prevent burns from molten materials or flames generated during the combustion process.

When placing the sample, it is necessary to ensure that the sample is vertically suspended in the sample holder, without tilting or wrinkling, and that the relative position between the sample and the igniter meets the standard requirements.

The ignition timing should be precise and operated strictly according to the standard prescribed ignition time to avoid ignition when it exceeds or falls short.

During the experiment, it is necessary to closely observe the combustion status of the sample and not leave the test bench without authorization. If abnormal combustion occurs (such as rapid flame spread), the gas source should be immediately cut off and fire extinguishing measures should be taken.

Precautions for cleaning after the experiment

After the experiment is completed, wait for the equipment to cool down before cleaning the sample residue and combustion ash to avoid high-temperature burns.

Clean the sample holder, combustion chamber, and other components of the equipment to remove residual combustion products and prevent them from affecting subsequent tests.

Turn off the gas main valve and equipment power supply, and keep good test records, including key data such as sample information, combustion time, and damage length.
