Washing, drying and measurement
Measures marked distances before and after the specified washing and drying procedure and cycle count.
Length and width are measured separately; garment results identify each measuring position.
EN ISO 5077
Dimensional change after washing and drying
Requirements & test methods
ISO 5077 determines dimensional change in fabrics, garments and textile articles after specified washing and drying procedures.
Dimensional change
Change (%) = ((Xt − Xo) / Xo) × 100. Xo: original distance; Xt: distance after treatment.
Negative: shrinkage. Positive: growth. Mean change rounded to the nearest 0.5%.
| Original distance Xo | After treatment Xt | Change |
|---|---|---|
| 500 mm | 485 mm | −3.0% |
| 500 mm | 510 mm | +2.0% |
| 500 mm | 500 mm | 0.0% |
