What is EN ISO 13938-1:1999+A1:2014?

EN ISO 13938-1:1999+A1:2014 is a technical standard that specifies the test methods for determining the bursting strength of textiles. Bursting strength refers to the ability of a fabric to resist the growth of holes or rupture when subjected to pressure or stretching forces. This standard helps in evaluating the durability and performance of textiles used in various applications, such as clothing, upholstery, and industrial fabrics.

Understanding Bursting Strength

Bursting strength is an important property of textiles as it often indicates their quality and suitability for specific purposes. It measures how much pressure or force a fabric can withstand before it tears or bursts. The bursting strength test involves subjecting a specimen to increasing hydraulic pressure until it breaks. The measurement is expressed in kilopascals (kPa) or pounds per square inch (psi).

Bursting Strength Test Methods

EN ISO 13938-1:1999+A1:2014 provides two primary methods for conducting the bursting strength test: the hydraulic method and the pneumatic method.

The hydraulic method involves using hydraulic pressure to apply force to the textile specimen until it bursts. The result is recorded as the maximum pressure reached when the fabric breaks. This method is commonly used for most types of textiles, including woven, knitted, and non-woven fabrics.

The pneumatic method, on the other hand, employs compressed air or gas to exert pressure on the fabric until it ruptures. Similar to the hydraulic method, the bursting strength is determined by measuring the maximum pressure at which the specimen fails. However, this method is typically used for testing lightweight fabrics and specialized materials like laminates or coated fabrics.

Significance and Application

The bursting strength test outlined in EN ISO 13938-1:1999+A1:2014 helps manufacturers, suppliers, and consumers assess the performance and durability of textiles. It ensures that the fabrics used in various products, from clothes to seat covers, meet the required quality standards. By testing bursting strength, potential issues like weak spots or structural vulnerabilities in the fabric can be identified before production or during quality control checks.

This standard is particularly essential in industries where textiles need to withstand high pressure or stretching forces. For example, it is crucial for automotive upholstery materials that must endure repeated stress and strain. Moreover, it is vital in applications such as medical textiles, outdoor equipment, and protective clothing, where the fabric's integrity and resistance to bursting are critical for safety and functionality.

In conclusion, EN ISO 13938-1:1999+A1:2014 is a technical standard that defines the methods for evaluating the bursting strength of textiles. This standard plays a significant role in ensuring the quality and suitability of fabrics for different applications, helping manufacturers and consumers make informed decisions about their textile choices.
