Any fabric can be called durable. Whether it is comes down to five separate tests, and they measure different failures — a cloth can pass one and fail another. A spec sheet that says "durable" without naming any of them is not a specification.
The five tests
| Property | What fails | Typical test |
|---|---|---|
| Abrasion | Surface rubs flat or through | Martindale, Wyzenbeek, Taber |
| Tear | Splits from a cut or notch | Tear strength |
| Tensile | Pulled apart under tension | Tensile strength |
| Pilling | Surface balls up | Pilling resistance |
| Colour fastness | Fades or rubs off | Colour fastness |
Why the numbers do not compare
Abrasion alone has three instruments that disagree — see abrasion resistance. A "40,000" figure means nothing until the instrument, abradant and load are named. The same fabric returns different numbers from each. That is the single most common durability-spec mistake.
What actually wears a piece out
A rub count is one failure mode. Real furniture and bedding also fail through:
- Seam slippage — the seam opens under load (seam slippage)
- Compression — foam and wadding collapse, not the cloth
- UV fading — the colour goes before the fabric does (light fastness)
- Shrinkage — dimensional change after washing (shrinkage rate)
A fabric rated highly for abrasion can still pill visibly or fade in a window.
What to put on the RFQ
- The test and the instrument by name, plus the standard (e.g. "to Martindale, ISO 12947-2")
- The end use — a tight upholstery seat and a loose curtain are different duty
- Minimum, or minimum and target — a minimum alone invites the lowest number that clears it
- The state tested — greige or finished, since finishes move the number
