ISO 2062 is an international standard for measuring the tracking properties of yarns. The standard contains several test methods, the most commonly used of which is the Single-end Breaking Force and Elongation at Break of Yarns Testing.
The purpose of this test is to measure the maximum force that a single yarn can withstand when stretched to the breaking point and the percentage increase in the original length of the yarn at break. These parameters are essential for assessing the strength, durability and reliability of yarns and have a significant impact on the quality and performance of textile products.
The testing procedure involves the use of a universal material testing machine and clamping a sample of yarn to the testing machine in accordance with ISO 2062. The tensile force applied to the yarn by the tester is then gradually increased until the yarn breaks. During the stretching process, the tester records the force applied to the yarn and the elongation of the yarn to give the breaking strength and elongation at break of the yarn.
ISO 2062 also specifies other test methods related to yarn tracking, such as yarn count, twist, density and length. These test methods can help assess the quality and performance of yarns and ensure compliance with relevant international standards and regulations.
In summary, ISO 2062 is an important international standard for assessing the quality and performance of yarns, and its single yarn breaking force and elongation at break test methods are among the most commonly used in the textile industry. The results of these tests can help textile companies to control quality, improve productivity and ensure that their products comply with relevant standards and requirements.
