What are the testing methods and instruments for the burning characteristics of textiles?
1. Fabric burning performance test: It is mainly used to test the burning breadth (carbonized area and damage length), continuous burning time and smoldering time of the sample. According to the relative position of the sample and the flame, it can be divided into vertical burning method, horizontal burning method and 45 degree burning test method. Test principle: The vertical combustion method is to set a certain size sample perpendicular to the specified combustion test box and ignite it with a specified fire source for 12 seconds. After the fire source is removed, the continuous burning time and smoldering time of the sample are measured, and the smoldering time is measured after stopping Damage length. The test principles of the horizontal test method and the 45-degree combustion test method are the same as those of the vertical test, and the ignition time is different. Compliant with standards: ASTM D6413-99, DOC-FF 3/71, CALIF TB-117, GB/T 5455, CPAI-84; ISO 3795, FMVSS 302, DIN 75200, SAE J369, ASTM D5132, JIS D1201, AU169, FZ /T 01028; ASTM D1230, FTMS 191-5908, CFR 16 Part1610, CAL IF TB117, NFPA702, GB/T 14644 2. Limiting oxygen index test: Limiting oxygen index: Under the specified test conditions, the material is kept in a burning state. The minimum concentration of oxygen in the mixed gas of nitrogen and oxygen. Test principle: Fix a sample vertically in a transparent combustion tube of upwardly flowing oxygen and nitrogen mixture, ignite the top of the sample, and observe the combustion characteristics of the sample, and compare the continuous burning time or the burning length of the sample with the Compared with the established criterion, the minimum value of oxygen concentration is estimated through a series of tests under different oxygen concentrations. Compliance with standards: ISO 4589-2, ASTM D2863, GB/T2406, GB/T5454 3. Smoke density test: Smoke density refers to the measurement of the amount of smoke produced by a material under specified test conditions, which reflects the degree of opacity of smoke. The higher the smoke density of the material, the more unfavorable it is for evacuation and fire fighting during a fire. Test range: The plastic burning smoke density tester is for the smoke density test of the sample from the sheet-shaped material, composite material, or composite parts with a thickness of no more than 25mm. This test instrument is not only suitable for all plastics, but also for rubber, textile coverings, painted surfaces, wood and other materials. Test principle: Place the sample horizontally in the test box, and expose the upper surface of the sample to a heat radiation source with a constant irradiance within 50KW/m2. The generated smoke is collected in a test box equipped with a photometer. Measure the attenuation of the beam after passing through the smoke. Compliance with standards: GB8323.2-2008, ISO5659.2-2006. IV. Combustion oxygen consumption and heat release rate test: The heat release rate and total amount of the material when burned are the most important parameters in its combustion performance, which can be compared Accurate measurement of the heat release rate during material combustion is very important for predicting fire hazards. At present, the main secondary test method is cone calorimetry. Test principle: The sample is burned under the heat radiation of the cone electric heater. The flame consumes a certain concentration of oxygen in the air and releases a certain heat of combustion. The instrument can measure the rate of heat release, the amount of CO and CO2 produced, the rate of oxygen consumption, and the amount of smoke released. Compliant with standards: ISO 5660, ASTM E1354, ASTM E1474, ASTM E1470, ASTM F1550, ASTM D6113, NFPA 264, CAN ULC135, BS 476. More about the combustion tester: http://www.ranshaoceshi.com/

Choosing the right abrasion testing equipment is essential for obtaining accurate and repeatable wear resistance results. DIN Abrasion Tester and Taber Abrasion Tester are two widely used abrasion testing machines, but they are designed for different material types and testing purposes.
This article provides a detailed comparison between DIN Abrasion Tester and Taber Abraser, covering their working principles, specimen requirements, industry applications, standard compliance, technical characteristics, operation features and practical advantages. DIN Abrasion Tester is mainly designed for rubber, elastic materials, tires, conveyor belts and footwear soles, while Taber Abrasion Tester is suitable for flat materials such as coatings, textiles, plastics, leather, metals and decorative surfaces.
By understanding the differences between these two abrasion testing methods, laboratories can select the most suitable abrasion tester based on sample geometry, testing standards and production quality control requirements.
The air permeability tester is a high-precision testing instrument designed to evaluate the breathability of PPE materials, textile fabrics, non-woven fabrics, woven fabrics, and industrial filter media. It plays a critical role in quality control, product development, and laboratory research across multiple industries including PPE, textiles, automotive interiors, and filtration systems.
Modern instruments such as the GT-C27 Air Permeability Tester are developed with advanced sensor systems, automated control logic, and multi-standard compatibility to ensure reliable and repeatable results. Complying with global standards such as ISO 9237, ASTM D737, DIN 53887, and GB/T 5453, it guarantees internationally recognized testing performance.
With high automation, accurate pressure sensing, and flexible unit conversion systems, air permeability testing equipment significantly improves testing efficiency while reducing human error. It is widely used in PPE manufacturing, textile engineering, non-woven product development, and industrial filtration quality inspection.
Safety gloves are critical personal protective equipment (PPE) used in industries such as manufacturing, welding, construction, firefighting and chemical processing. To ensure reliable protection, gloves must undergo strict performance testing before entering the market.
Professional gloves testing equipment helps manufacturers evaluate important properties including cut resistance, thermal protection, contact heat resistance, tensile strength and impact protection. By selecting suitable testing machines, companies can improve product quality, meet international standards and reduce safety risks.
This complete buying guide introduces the main types of glove testing equipment, explains their applications and provides practical advice on choosing the right solution for your laboratory or production requirements.
