ISO 9073-2:2016, also known as the International Organization for Standardization (ISO) standard for Textiles – Test methods for nonwovens – Part 2: Determination of thickness, is a technical specification that outlines the procedure for measuring the thickness of nonwoven fabrics. Nonwoven fabrics are materials made from fibers that are bonded together mechanically, thermally, or chemically rather than woven together.
Importance of Measuring Thickness
Measuring the thickness of nonwoven fabrics is crucial for several reasons. First, it helps determine the quality and performance of these fabrics. The thickness affects their insulation properties, strength, absorbency, and other functional characteristics. Second, manufacturers need to meet certain thickness standards to ensure consistency in the production process. Third, customers rely on accurate thickness measurements to select appropriate materials for their intended applications.
Procedure for Measuring Thickness
The ISO 9073-2 standard provides a standardized method for measuring the thickness of nonwoven fabrics. This method involves using an apparatus called a thickness gauge. The fabric sample is placed between two pressure plates, and the gauge applies a specified load to compress the sample. The thickness is then measured using a micrometer or other suitable device. Several readings are taken at different locations on the fabric, and an average value is calculated.
Benefits of Using ISO 9073-2:2016
The use of ISO 9073-2:2016 brings several benefits to manufacturers, suppliers, and customers of nonwoven fabrics. Firstly, using a standardized method ensures consistent measurements across different laboratories and testing facilities. This helps avoid discrepancies and promotes fair trade practices. Secondly, the standard provides clear guidelines on the equipment, sample preparation, and testing conditions required, ensuring accuracy and reliability of results. Finally, adherence to ISO 9073-2:2016 enhances the quality and safety of nonwoven fabrics, allowing end-users to have confidence in their performance.
