What is BS EN ISO 391:2012?

BS EN ISO 391:2012, also known as "Textiles - Determination of mass per unit length and mass per unit area," is a standard developed by the British Standards Institution (BSI) and the International Organization for Standardization (ISO). It provides guidance on the measurement of fabric density in terms of mass per unit length and mass per unit area. This technical article aims to provide an in-depth understanding of BS EN ISO 391:2012 and its implications for the textile industry.

Importance of Fabric Density Measurement

Fabric density, often measured as mass per unit area or mass per unit length, is a critical parameter in the textile industry. Measuring fabric density helps determine the quality, performance, and characteristics of textile products. It enables manufacturers to ensure consistency in their products, meet regulatory requirements, and address customer expectations. Proper fabric density measurement is essential across various applications, including apparel, home textiles, industrial fabrics, and technical textiles.

Key Parameters in BS EN ISO 391:2012

BS EN ISO 391:2012 specifies the procedures and techniques for measuring fabric density accurately. It outlines three main parameters:

Determination of mass per unit length: This parameter measures the mass of a specific length of fabric. It helps evaluate the linear density and thickness uniformity of the fabric.

Determination of mass per unit area: This parameter measures the mass of a defined area of fabric. It is crucial for assessing the areal density, which affects the fabric's strength, durability, and breathability.

Calculation of fabric thickness: This parameter focuses on evaluating the thickness of the fabric using either an electronic or mechanical technique. It assists in understanding the fabric's bulkiness and its potential applications.

Benefits of BS EN ISO 391:2012 Compliance

Compliance with BS EN ISO 391:2012 offers several benefits to manufacturers and consumers alike. Firstly, it enables manufacturers to produce textiles that meet international quality standards, enhancing their market competitiveness. Secondly, it provides consumers with the assurance that the textile products they purchase have undergone rigorous fabric density testing, ensuring reliability and durability. Additionally, compliance with this standard helps prevent trade barriers by facilitating global acceptance and harmonization of fabric density measurement methods.
