EN ISO 13936 Seam slippage resistance testing
The EN ISO 13936 standard provides a standardized method to determine the seam slippage resistance of fabrics and textile products. This test is critical for ensuring that seams remain intact under stress, which is essential in sectors such as apparel manufacturing, automotive interiors, and industrial textiles.
Seam slippage occurs when the layers of fabric within a seam start to move relative to each other, leading to potential failure of the product. This can have severe implications for the integrity and safety of products like seat belts in vehicles or protective clothing used by workers in harsh environments. By conducting this test as per EN ISO 13936, manufacturers can ensure that their seams meet stringent quality standards, thereby enhancing both functionality and longevity.
The testing process involves clamping a sample of fabric containing the seam between two fixtures. One end of the sample is pulled in one direction while the other remains stationary, creating tension along the length of the seam. The rate at which slippage occurs over time or until failure provides critical insights into the strength and durability of the seam.
Accurate specimen preparation is crucial for reliable test results. Samples should be cut from a single piece of fabric to ensure homogeneity. Pre-treatment steps such as washing and drying may also be necessary depending on the specific requirements outlined in the standard. After preparing the samples, they are mounted into the testing machine according to the specified protocol.
The choice of instrumentation plays a vital role in obtaining precise results. High-quality mechanical testers equipped with appropriate grips for fabric samples are recommended. These instruments must be capable of applying controlled loads and measuring displacement accurately. Regular calibration ensures consistent performance throughout multiple tests.
Acceptance criteria vary based on the intended use of the textile product. For example, automotive seat belts require higher seam slippage resistance than casual clothing items. Compliance with relevant national or international standards is often required by law, making adherence to EN ISO 13936 essential for manufacturers aiming to meet regulatory requirements.
In summary, conducting seam slippage tests according to EN ISO 13936 offers valuable information about the robustness of seams in textiles. It helps identify potential weaknesses early on during development stages or production processes, allowing corrective actions to be taken promptly if needed. Ultimately, this contributes towards producing high-quality textile products that are safe and reliable for end users.

Applied Standards
The EN ISO 13936 standard specifies the method for determining seam slippage resistance using a tensile tester. This international standard is widely recognized and adopted by industries worldwide to ensure consistent testing procedures across different regions.
The key aspects covered in this standard include:
- Test specimen preparation
- Tension force application
- Measurement of displacement
- Determination of seam slippage resistance value
The standard also provides guidance on selecting appropriate test parameters based on the type and thickness of fabric being tested. Compliance with these guidelines ensures accurate comparison between different products or versions within the same product line.
Industry Applications
- Automotive industry: Ensuring safety in seat belt assemblies by validating seam integrity under various loading conditions.
- Aerospace sector: Quality control for aircraft interiors, where maintaining fabric integrity is paramount to passenger comfort and safety.
- Construction field: Verification of structural components like roof membranes or wall coverings that rely heavily on seam strength for durability.
- Military applications: Testing protective clothing and equipment subjected to rigorous stress tests in harsh environments.
Environmental and Sustainability Contributions
By ensuring that seams remain intact over time, EN ISO 13936 contributes significantly to reducing waste associated with premature product failure. This leads to prolonged product lifespan which aligns well with sustainability goals.
In addition, meeting these standards helps promote responsible sourcing practices by encouraging the use of durable materials throughout supply chains. Consumers benefit from longer-lasting products that require fewer replacements, contributing positively towards circular economy principles.
