Horizontal and Vertical Burning Ratings
FAQ 7 11 月, 2025 79
With the increasing public awareness of fire safety and the issuance of relevant national standards, the domestic combustion testing industry is experiencing an upward trend. Many newcomers to the combustion testing industry are unfamiliar with horizontal and vertical burning ratings. Today, I will provide an introduction. The UL94 standard, being consistent with China’s national standard GB/T 2408-2008. has become the most common test met
What a Tribometer Measures
FAQ 3 11 月, 2025 51
A tribometer is a precision instrument designed to measure frictional forces and wear characteristics between surfaces in contact. It quantifies two fundamental types of friction: Static Friction: The resistance that prevents initial movement between two stationary surfaces. Kinetic Friction: The resistance encountered during relative motion between surfaces. These measurements enable the calculation of coefficients of friction (both static and
What is the Oxygen Index?
FAQ 23 10 月, 2025 107
The Oxygen Index (OI) refers to the minimum oxygen concentration required for a material to sustain stable combustion in an oxygen-nitrogen mixture under specified test conditions, expressed as the volume percentage of oxygen. This concept was first proposed by American scientists Fenimore and Martin in 1966 and has since become an internationally recognized method for evaluating the flame retardancy of materials. A higher OI indicates a less fla
What is Bacterial Filtration Efficiency (BFE)?
FAQ 13 10 月, 2025 88
In disease prevention and control, as well as in everyday health care, masks have become an indispensable barrier. However, not all masks offer the same level of protection. One of their core performance indicators is Bacteria Filtration Efficiency (BFE). BFE directly measures the mask material’s most critical ability to block bacterial droplets. Whether in surgical settings, protecting patients from respiratory droplets from doctors, or in
Why is textile quality important?
FAQ 17 6 月, 2025 186
Why is textile quality important? The answer to this question may appear to be self-evident, but some aspects may not be so clear. We will highlight some of these here. Studies say there is a strong link between product quality and return on investment. Firms that produce better-quality goods tend to have a bigger market share. Importance of high-performance tests in textiles Firefighters’ uniforms protect against flames and heat. They als
Several common methods for testing the combustion properties of textiles
FAQ 3 6 月, 2025 201
1. The combustion properties of textiles: The combustion of textiles is a complex process. Their flammability in addition to the chemical composition of the fibers but also with the fabric structure and fabric dyes and other substances on the nature of the relevant. For ordinary taking textiles, the performance of the material itself is the determining factor of its combustion characteristics. Fiber by combustion properties are generally divided
How to use the fiber fineness analyzer correctly?
FAQ 3 6 月, 2025 186
Fiber fineness analyzer is a new type of human-computer interaction fiber diameter measurement analyzer. The instrument through the high-resolution industrial camera will be connected to the optical microscope and computer, relying on professional analysis software to complete the fiber diameter and cross-sectional area of the test and so on, can be used to measure wool, rabbit hair and other animal fiber diameter measurement and a variety of nat
