ISO 13938 Textiles, Bursting Properties of Fabrics
ISO 13938 is a test procedure to ascertain the bursting behavior of textile fabrics. Such properties are of utmost importance in applications where fabrics are exposed to multi-directional stress, e.g., upholstery, technical textiles, and protective clothing. The standard contains procedures to conduct both hydraulic and pneumatic bursting tests to give accurate information on the strength of fabric and overall performance under pressure. That is why materials must fulfill specifications of performance, safety, and durability in a huge variety of industries.

ISO 13938 Introduction
ISO 13938 provides a uniform procedure for determining the bursting of a fabric with the help of a hydraulic or pneumatic apparatus. The results are useful in determining whether the product is suitable for making end-use products for manufacturers, researchers, and product developers. Fabrics are usually subjected to stress in more than one direction at the same time, unlike tensile forces, which occur in one direction only. A bursting strength test determines the strength of fabrics against such forces and is therefore a critical quality control and research tool in the textile sector.
ISO 13938Test Method
Procedure
A fabric specimen is securely clamped over a flexible diaphragm. Pressure is applied at a controlled rate, causing the diaphragm to expand and exert force on the fabric until it ruptures. The bursting strength and, where applicable, the distension at burst are recorded.
Apparatus
A bursting tester capable of applying hydraulic or pneumatic pressure with a pressure gauge or sensor to measure the applied force. The clamping device must hold the fabric firmly without slippage.
Specimen Preparation
Test specimens are cut to standard sizes, free from wrinkles and folds, and conditioned under standard atmospheric conditions for testing textiles (usually 21 ± 1 °C and 65 ± 2% RH).

Specimen Details
Flat textile specimens, free from folds and damage, cut to specified dimensions.
Specimen Preparation
Conditioned in a standard atmosphere for textiles (20 ± 2 °C, 65 ± 4% RH) before testing.
Specimen Dimensions
Large enough to cover the test head with allowance for clamping (typically 100 mm × 100 mm).
ISO 13938 Results and Interpretation
The test gives values of pressure bursting (strength) and of bursting distension (amount of expansion before rupture). The greater the values, the stronger the fabrics, which are more durable in multi-directional stress. The results obtained are dependent upon the structure of the fabric, the fiber utilized, and the finishing technique of the fabric. Fabrics such as knitted and stretch fabrics usually exhibit more distension with reduced bursting strength compared with tightly woven fabrics, with high bursting strengths.
ISO 13938 Related Test Methods
The method of measuring the bursting strength of textile fabrics with a diaphragm-type, as given by ASTM D3786, extends its inspection to somewhat similar purposes. ISO 13934 specifies explicitly the tensile properties of fabrics and measures the changing force and elongation throughout the breaking process, thus supplementing the bursting strength measurements with a measurement of fabric performance under uniaxial strain.
ISO 13938 Applications in Industry
This method has been commonly used to test upholstery materials, airbags, medical textiles, industrial fabric, athletic apparel, and protective clothing, where the ability to handle multi-directional loads is essential. It is especially important in the assessment of nonwoven and knitted fabrics in hygiene products, filtration media, and technical applications.
ISO 13938 Materials Commonly Tested
Common test specimens include woven (cotton, polyester, blends), knit (circular, warp-knit), nonwoven, coated textile, upholstery, and technical fabric (automotive / aerospace / protective and body armor).
ISO 13938 Common Challenges and Troubleshooting
The challenges may be due to inadequate specimen preparation, wear of the diaphragm, and/or slippage of the fabric during clamp-ionizing, which can lead to non-uniform results. Errors are minimized when conditioning is done properly, the appropriate amount of clamping pressure is applied, and when the equipment is frequently calibrated.
ISO 13938 Safety and Best Practices
Routine equipment care, proper calibration, and follow-up of conditioning procedures are also part of best practices to attain decisive and detectable, as well as reproducible outcomes.
Importance of ISO 13938 Test Method
This method is a vital provision for making fabrics fit into the functions of demanding applications in terms of performance and safety aspects. Evaluation of bursting strength enables manufacturers to determine how fabrics will perform under practical operating conditions and determine how the products will provide durability, wearability, and safety to end users.
