In short
- Martindale cycles and Wyzenbeek double rubs don’t convert. Compare only results from the same method.
- ACT’s contract benchmarks: 15,000 double rubs or 20,000 cycles for low traffic; 30,000 or 40,000 for high traffic.
- Abrasion doesn’t predict lifespan or snag resistance. Ask for those separately.
Martindale vs Wyzenbeek at a Glance
| Wyzenbeek | Martindale | |
|---|---|---|
| Standard (US) | ASTM D4157 | ASTM D4966 |
| Unit | Double rubs | Cycles |
| Motion | Back and forth in a straight line | Overlapping figure-of-eight (Lissajous) pattern |
| Where you’ll see it | Mostly North American specifications | Mostly European, UK and Asian specifications |
| ACT low traffic / private spaces | 15,000 double rubs | 20,000 cycles |
| ACT high traffic / public spaces | 30,000 double rubs | 40,000 cycles |
The benchmarks are the Association for Contract Textiles’ (ACT) voluntary guidelines for woven indoor upholstery. They are minimums for contract use, not a ranking above that level.
Can You Convert Martindale to Wyzenbeek?
No. ACT states plainly that there is no correlation between Wyzenbeek and Martindale results. The machines rub the fabric differently, under different arrangements, so a fabric’s double-rub count tells you nothing reliable about its Martindale result. Conversion tables found online have no basis in either standard.
If one fabric has only a Wyzenbeek report and another only Martindale, compare each against the benchmark for its own method and the intended use. If your specification requires one method, ask for a report in that method rather than estimating it from the other.
Is a Higher Rub Count Better?
Up to the benchmark for the use, yes. Beyond it, not necessarily. ACT cautions that abrasion results are not a reliable indicator of fabric lifespan: twice the rub count does not mean twice the service life. It also notes that repeated tests on some woven fabrics can vary by 60 percent or more.
So a fabric reported at 100,000 double rubs is not automatically better for a hotel lobby than one at 50,000. Both clear the high-traffic guideline; after that, weave, fibre, colour and cleaning matter more than the extra rubs.
How to Read an Abrasion Report
- Check the fabric code and colour on the report match the fabric quoted for your sofa, including any backing or finish.
- Note the method and edition named, the result with its unit, and the end point used to stop the test.
- If a supplier writes only “rub count”, treat the method as unconfirmed until the report names it. Don’t assume it’s Martindale because the rest of your schedule is.
- Keep the method visible in your comparison sheet: separate columns for fabric code, method, result and intended use.
Where no report is available for a fabric, record the result as “not supplied” instead of borrowing a score from a similar-looking one.
Does a High Abrasion Rating Mean the Fabric Resists Snags?
No. Abrasion is surface wear from friction. Snagging is a yarn being caught and pulled, by pet claws, jewellery, zips or rivets on clothing. A fabric can score well on abrasion and still snag easily, especially loose weaves and textured fabrics like bouclé.
Snagging has its own tests. ASTM D3939 (the mace test) covers many woven and knitted fabrics but excludes some constructions, such as tufted and nonwoven fabrics, and its scope notes that other methods may suit some end uses, including upholstery. Ask the fabric supplier which snag test, if any, fits the fabric you’re considering.
If pets or heavy use are the concern, say so in the brief and ask for snag information for that fabric code. Don’t drag keys or claws across a showroom sample as a test. A good snag result also isn’t a promise that a pet will never damage the cover.
What Abrasion Doesn’t Cover
A full fabric decision also needs seam slippage (yarns pulling apart beside a seam), lightfastness for bright rooms, and the approved cleaning method. An abrasion report doesn’t say which cleaner is safe. The sofa fabric guide covers these checks, including seam slippage, and gives a fabric approval record.
Asking YEINIHOME About Fabric Ratings
In your enquiry, send the fabric reference and say where the sofa will be used: guest rooms, a public lobby or a home with pets. Ask for the abrasion report available for that fabric code, and snag information if that’s a concern. If a fabric has no report, record its rating as unverified in your comparison.
Frequently Asked Questions
Is a Martindale cycle the same as a double rub?
No. They come from different methods and don’t correlate. Keep each result in its own unit.
What Martindale rating is good for a sofa?
For contract use, ACT’s guideline is 20,000 cycles for low-traffic private spaces and 40,000 for high-traffic public spaces.
What Wyzenbeek rating is good for a hotel sofa?
ACT’s high-traffic guideline is 30,000 double rubs; low-traffic private spaces use 15,000.
Can I turn a rub count into years of use?
No. Neither result predicts a number of years for a particular sofa.
Is snagging the same as pilling?
No. Snagging is a pulled yarn; pilling is small balls of fibre forming on the surface. Each has its own test.
