Benchmarking standard: GB/T5725 Safety net flame retardant equipment and GB5455/T compatibility analysis

The core competitiveness of GB/T5725 safety net flame retardant testing equipment lies in its adaptability to the GB/T545-2014 standard, which is reflected in multiple dimensions such as testing principles, technical parameters, and testing indicators. This adaptability is the key to the equipment's ability to determine the flame retardant performance of safety nets.

From the perspective of experimental principles, GB5455 standard adopts the vertical combustion method to simulate the combustion state of safety nets when suspended vertically in actual use. The design of GB 5725 equipment revolves around the vertical combustion test, and the sample clamping device, burner position, etc. strictly follow the standard requirements to ensure that the test scenario is consistent with the standard regulations.

In terms of technical parameters, the benchmarking standards for various indicators of the equipment require that the flame height can be stably controlled at 40mm, which meets the requirements of the standard for ignition sources; The timing accuracy reaches 0.1 seconds, meeting the precise measurement requirements for afterburning and smoldering time; The measurement accuracy of the damaged length reaches 1mm, which is consistent with the measurement accuracy required by the standard. The matching of these parameters ensures the validity of the detection data.

In terms of detection indicators, the equipment can comprehensively collect all indicators specified in GB 5455 standard, including ignition time, smoldering time, and damage length. At the same time, it can record additional information such as whether the sample has molten droplets, meeting all the requirements of the standard for determining combustion performance. Beijing Xinsheng Zhuorui Technology Co., Ltd. develops, produces and supplies GB5725 safety net flame retardant performance tester

Scope of application: GB5725 touch screen controlled safety net combustion performance (flame retardant) tester, also known as textile vertical combustion tester, is suitable for measuring the combustion (flame retardant) performance of various safety flat net vertical net dense mesh safety vertical net.

The GB5725 touch screen controlled safety net combustion performance (flame retardant) tester shall be tested according to the method specified in 6.1.6 of section 5.1.12 of GB5725 safety net for flame retardant performance and flame retardant flat (vertical) net. The duration of continuous combustion and smoldering should not exceed 4 seconds. According to the flame retardant performance of 5.2.2.9, the flame retardant performance of the dense mesh safety net shall be tested according to the testing method specified in 6.2.12. The continuous burning and smoldering time in the horizontal and central directions shall not exceed 4 seconds. The testing requirement is to randomly take five ropes with a length of 300 ± 5mm from the sample net, and test them according to the method specified in GB5455, with the results rounded to one decimal place.

In addition, the test environment control function of the equipment is also compatible with the standard, which can control the test environment temperature at (23 ± 2) ℃ and the relative humidity at (50 ± 5)%, meeting the test conditions specified in the standard and avoiding interference from environmental factors on the detection results. This overall adaptability makes GB 5725 equipment a testing tool for implementing the GB 5455 standard.
