This standard describes in detail the method for the determination of volatile organic matter emissions from Spinning & weaving materials for automotive interiors using the box method. It is suitable for all types of Spinning & weaving materials for automotive interiors, including woven fabrics, knitted fabrics, nonwovens, coated fabrics and composite fabrics. This standard refers to HJ/T400-2007 "Methods for the sampling and determination of volatile organic matter and aldosteroids in vehicles" to ensure the standardization and comparability of test methods. This standard covers a number of key terms and definitions, such as total vocs (TVOC), total hydrocarbon mass concentration, vocs (VOC), test chamber, gas exchange rate and airflow velocity, etc. These terms and definitions ensure the accuracy and conformity of the testing process, making the results comparable and reliable. These measures are designed to increase the contribution of automotive interior materials to the air mass of the environment, ensuring that in practical use there are no harmful effects on passengers and the environment.
