Strip specimen and gauge length
Strip width: 50 ± 0.5 mm, excluding fringe. Gauge length: 200 mm, or 100 mm when expected elongation at maximum force exceeds 75%.
Results identify fabric direction, dry or wet conditioning, width and gauge length.
EN ISO 13934
Tensile properties of fabrics
Requirements & test methods
ISO 13934-1 measures the maximum tensile force and elongation at maximum force using a strip specimen.
Maximum force and elongation
A constant-rate-of-extension machine measures force and extension as the strip is pulled.
Maximum force in N; elongation in %, by fabric direction.
| Quantity | Example result | Interpretation |
|---|---|---|
| Maximum force | 600 N | Largest force reached during the test |
| Elongation at maximum force | 20% | 40 mm extension over a 200 mm initial gauge length |
