EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of EN ISO 20932-3 testing. This standard specifies test methods that can be used to measure the elasticity and related properties of narrow fabrics.
Two methods are listed:
A narrow test specimen with certain length dimensions is stretched at a constant rate up to a certain force for the agreed number of cycles. Various properties can be measured to determine the performance and profile of narrow fabric.
A narrow test specimen with certain length dimensions is stretched at a constant rate to a given force and elongation for one cycle of a given row. Properties are measured to show the narrow fabric's performance in use.
Pneumatically actuated grips are recommended, as hand tightening or manual gripping can cause test specimen deterioration. The air pressure should be sufficient to prevent slipping while compensating for the reduced thickness of the fabric, but should not shear or otherwise weaken the test specimen.
The flexibility of narrow fabrics is an important property that affects their behavior and performance in a variety of applications. The standard involves subjecting a narrow fabric sample to controlled deformation and measuring the resulting force and elongation. The data obtained are used to calculate the elastic properties of the fabric, such as Young's modulus and Poisson's ratio.
The standard specifies the equipment and procedures required for testing, including preparation of samples and application of loads. It also provides guidelines for reporting the results of tests.
Using this standard, manufacturers, designers and researchers can determine the stretch properties of narrow fabrics with high accuracy and consistency. This knowledge can be used to develop tight fabrics with specific performance characteristics and ensure that they meet the required quality standards for a variety of applications such as the apparel, automotive and medical industries.
