The QB/T 2728 standard published by the China Leather Industry Standardization Technical Committee describes test methods for determining leather fogging properties, including reflection method (Method A) and mass method (Method B). The standard applies to automotive upholstery leather and leather furniture with anti-fog resistance requirements.
This standard includes the technical requirements, test methods, inspection rules, marking, labeling, packaging, transportation and storage of leather products. This standard applies to all kinds of daily leather goods.
Volatile matter content in vehicle interior accessories is an important factor affecting the vehicle's interior environment and line of sight. In the production and functional improvement process of automotive interior accessories, small molecular substances are likely to be added to them, and these added substances are volatile. These substances are more volatile, especially when the car's interior temperature is high. Small molecular substances that evaporate from vehicle interior accessories may float in the air, pollute the air environment inside the vehicle, endanger human health after inhalation, or condense on the vehicle glass, adversely affecting the driving line and threatening driving safety. Therefore, how to test the volatile content in automotive interior parts is a common concern in the automotive industry. The QB/T 2728 standard responds to this need.
The content of volatile substances in automotive interior parts is mainly characterized by fogging performance, which is verified by fogging tests, which include three test methods (gloss method, haze method and weighing method). The first two of these focus on assessing the impact of volatile substances. Today, among these three methods, the weighing method and the gloss method are widely used.
In this regard, the following two standards are also complied with:
Our organization, among the numerous test, measurement, analysis and evaluation studies it has given for businesses in various sectors, with its trained and expert staff and advanced technological equipment, within the scope of the QB/T 2728 standard, for the determination of leather fogging properties (photometric method) between physical and mechanical tests. It also provides testing services.
