ISO 7211-3 Textiles Determination of mass per unit length
The ISO 7211-3 standard provides a method to determine the mass per unit length (mass/meter or grams per meter) of textiles. This parameter is crucial for quality control, product specification compliance, and ensuring uniformity in textile manufacturing processes.
The test involves measuring the weight of a specific length of textile material using calibrated precision scales. The specimen is cut into a known length with consistent edges to ensure accurate results. The mass per unit length is calculated by dividing the measured mass (in grams) by the length of the sample (in meters).
ISO 7211-3 applies primarily to woven and knitted fabrics, but it can also be used for non-woven materials like felts or spunbonded fabrics. The standard specifies that samples should be conditioned in a controlled environment with temperature and humidity levels maintained at specified values before testing.
The equipment used for this test includes precision scales capable of measuring to an accuracy better than ±0.1 gram, along with tools for cutting the specimen accurately to the required length. The standard also recommends using reference materials to calibrate the measurement process and ensure consistent results across different laboratories.
Once the sample is prepared and conditioned according to ISO 7211-3 requirements, it is cut into a specified length. The cut edges should be trimmed if necessary to remove any irregularities. After cutting, the specimen is placed on the scale for mass measurement. It’s important that the sample is not stretched or compressed during weighing to avoid altering its true mass per unit length.
The results of this test are used in several ways within a manufacturing environment. Quality control teams use it to ensure incoming materials meet specifications and outgoing products comply with standards. R&D engineers may use these measurements to compare different fabric types or evaluate the impact of changes made during development stages. Procurement personnel can rely on this data when negotiating with suppliers, ensuring they are receiving high-quality raw materials.
Compliance officers find ISO 7211-3 particularly useful for verifying that products meet international standards such as those set by CEN, IEC, or other regional bodies. These measurements are critical in industries ranging from apparel to automotive interiors, where fabric quality directly impacts product performance and safety.
In summary, ISO 7211-3 is an essential tool for textile manufacturers aiming to produce consistent products that meet stringent technical requirements. By accurately determining the mass per unit length of their fabrics, companies can enhance product quality, improve process efficiency, and maintain compliance with relevant regulations and industry benchmarks.
