Short answer: a fabric test report is only useful if you check four things before you read any result: who tested, what was tested, which method and conditions were used, and what requirement the result is compared with. Only after that do the numbers mean anything. A "pass" on a report you have not checked can still lead to a returned container.
Why this matters more than the price per meter
Two velvets can look and feel the same on a sample card and behave very differently on a sofa. One keeps its pile for years. The other bald-spots on the armrest within a season. The only objective evidence you have before ordering is the test report. Yet most buyers glance at the last page, see the word "pass" and move on. That habit is where most disputes start.
At Haihong, a manufacturer of sofa and home textile fabrics since 1988 with a vertically integrated chain from yarn texturing to finishing (see our vertical integration page), we see the same questions repeatedly from importers and furniture makers. This guide answers them in the order you will actually meet them.
Step 1: Read the report's anatomy before the results
Almost every report from a competent laboratory has the same parts. Knowing where each one sits lets you audit a report in under two minutes.
| Section | What it contains | What to check |
|---|---|---|
| Header | Laboratory name, report number, issue date, applicant | Is the lab independent or in-house? Does it hold accreditation (for example ISO/IEC 17025)? Is the report recent? |
| Sample description | Article number, color, composition, weight, construction | Does it match your article and color? Is it the finished fabric or a greige or lab-dip sample? |
| Test items and methods | Standard numbers, conditioning, test settings | Is the method the one in your specification? Is the standard's edition year shown? |
| Results | Numbers, grades, observations, photos | Units, end point, direction (warp or weft), wet or dry, and whether it is a mean or the lowest value |
| Requirement and conclusion | Limits and a pass/fail statement (not always present) | Whose limit is it? A lab usually applies the limit the client supplied, not an industry law. |
| Remarks and disclaimers | "Results relate only to the sample tested" | This line is why one report cannot vouch for every production lot. |
Step 2: Five questions to ask before you trust any number
- Does the sample identity match what you are buying? Dark colors and light colors of the same fabric can produce very different rubbing and light results. A report for navy does not prove the performance of cream.
- Is it the finished fabric? Backing, lamination and finishing change abrasion, tear strength and flammability behavior. Results from an unfinished sample are not transferable.
- Which method and which edition? "Abrasion: 50,000 cycles" means little without knowing whether it was Martindale or Wyzenbeek, and what counted as failure.
- What is the end point? Many abrasion results read "no breakdown after 40,000 cycles". That means the test was stopped there, not that the fabric failed at 40,000. It is a floor, not a measurement.
Is the date reasonable? A report from three years ago may describe an older formulation, yarn supplier or dye recipe. Ask for a report on the current production standard.
Step 3: Read the key tests for upholstery
The table below covers the tests that decide whether a sofa fabric survives real use. The "common starting point" column reflects widely used trade expectations, not legal minimums. Requirements differ by country, customer and application, so always confirm against your own specification.
| Property | Common method | How to read the result | Common starting point |
|---|---|---|---|
| Abrasion (Martindale) | ISO 12947-2 | Cycles reached before two yarns break (or no breakdown at the stop point). Higher is better. | About 20,000–30,000 for everyday domestic sofas; 40,000 or more for heavy use |
| Abrasion (Wyzenbeek) | ASTM D4157 | "Double rubs" before visible wear. Not interchangeable with Martindale cycles. | 15,000 double rubs general; 30,000 heavy duty (common contract guidance) |
| Pilling | ISO 12945-2 | Grade 1–5. 5 means no change; 1 means severe pilling. | Grade 4 or higher |
| Color fastness to rubbing | ISO 105-X12 / AATCC 8 | Staining on a white cloth, graded 1–5, reported dry and wet. Wet is almost always lower. | Dry 4; wet 3 to 4 (dark shades are the hardest) |
| Color fastness to light | ISO 105-B02 (xenon arc) | Blue Wool scale 1–8. Each step roughly doubles light resistance. | 4 to 5 minimum; higher for sun-exposed furniture |
| Tensile and tear strength | ISO 13934-1, ISO 13937-2 (or ASTM equivalents) | Force in newtons, reported separately for warp and weft. The weaker direction governs. | Set by your own specification |
| Seam slippage | ISO 13936-2 / ASTM D4034 | Seam opening in millimeters at a stated load. Smaller is better. | Often a ~6 mm limit at 120 N; confirm for your market |
| Flammability | Varies by market (for example BS 5852, EN 1021, California TB 117-2013, 16 CFR 1640) | Pass/fail against a defined ignition source, on a fabric-plus-filling combination. | Whatever the destination market legally requires |
| Restricted substances | For example ISO 14184-1 (formaldehyde), EN ISO 14362 (azo amines) | mg/kg values or "n.d." (not detected) against the limit in force. | Destination-market rules or your chosen certification program |
Abrasion: the number everyone quotes and few read correctly
Martindale and Wyzenbeek use different motions, abradants and failure definitions, so a Martindale cycle count cannot be converted into Wyzenbeek double rubs. Compare like with like. On pile fabrics such as velvet, ask how the lab judged failure. Yarn breakage may not happen for a very long time, while the pile flattens or sheds much earlier. For velvet, the photographs or written observation of pile appearance after testing are often more informative than the cycle count.
Color fastness: always look at both columns
Fastness reports usually give two grades per condition: color change of the sample and staining on the adjacent white cloth. A fabric can hold its own color well and still transfer dye onto a light-colored garment or bedsheet. For sofas, wet rubbing and perspiration results matter most because that is how real-world staining happens. A "4-5" is a half-step grade, which means it sits between 4 and 5. It is not a typo.
Flammability: the most misunderstood line on the report
Upholstery fire behavior depends on the fabric, the interliner, the foam and the construction together. A fabric-only report can show that the textile is suitable for a given test, but it rarely proves that the finished sofa complies. If a regulation applies in your destination country, ask which combination was tested and whether that matches your actual filling.
Coated and tech leather fabrics need extra tests
For polyurethane-coated or laminated materials, such as our Tech Leather & Fabric series, look beyond abrasion. Ask for hydrolysis resistance (often called the "jungle test", run at elevated temperature and humidity for several weeks, commonly 5 to 8 depending on the customer), flex resistance and cold-crack results. These reveal the failures buyers complain about most: surface peeling, cracking and stickiness after a year or two. A report with only abrasion and color fastness for a coated fabric is incomplete.
Step 4: A worked example (illustrative values)
The values below are invented to show the reading process. They are not Haihong test data.
| Line on the report | Plain-language meaning | Follow-up question |
|---|---|---|
| Martindale: no breakdown at 40,000 cycles | Strong result, but the test stopped at 40,000. True limit is unknown. | How did the pile look afterward? |
| Pilling: grade 4-5 | Very slight surface change. Good. | Tested on the dark or light colorway? |
| Rubbing: dry 4-5, wet 3 | Dry is fine. Wet transfer is noticeable, which matters if light clothing or covers touch the sofa. | Is the color a deep shade? Wet 3 is common there, but it should be disclosed. |
| Light: grade 5 | Good for normal indoor use. | Is the sofa placed beside a large window? |
| Formaldehyde: n.d. | Below the detection limit. | What was the detection limit stated on the report? |
Notice that none of these lines is a simple pass or fail. Each one triggers a practical question. That is the habit that separates a careful buyer from a hopeful one.
Step 5: Spot the red flags
| Red flag | Why it matters | What to do |
|---|---|---|
| Article number or color does not match your order | The report describes another product. | Request a report for the exact article and color. |
| No standard numbers, only "abrasion test: pass" | The result cannot be verified or compared. | Ask for the full report with methods and values. |
| Missing report number, issue date or lab contact | It cannot be traced or confirmed with the lab. | Ask the lab to confirm the report number. |
| Edited screenshots, cropped pages or inconsistent fonts | Possible alteration. | Ask for the original file directly from the lab. |
| Only the best result shown (for example light fastness but no rubbing) | The weak points may be hidden. | Define the full test list in your purchase specification. |
| Very old report | Production may have changed since. | Ask for a recent lot test or pre-shipment test. |
Turn the report into a purchasing tool
The most reliable way to use test reports is to write your requirements before you request quotations. A short specification that lists each property, the method, the minimum value and the sample basis (color, finished fabric, production lot) prevents most arguments. Then a report becomes a simple comparison against a list you wrote yourself. Our guide to the 10 essential things to confirm when purchasing sofa fabric for the first time pairs well with this one. For cross-border orders, see how to import sofa fabric from China, and for planning order sizes, our technical note on MOQ for sofa fabrics.

How Haihong approaches testing and documentation
Haining Haihong New Material Co., Ltd was founded in 1988 and operates from Haining, Zhejiang, with a 28,000 m² site and about 300 staff. We control draw-texturing, warp knitting, printing, foiling, lamination and embossing in one chain, so changes in yarn, dyeing or finishing can be traced to the stage where they happened. Our service page describes product testing as part of delivery, with advanced equipment and methods used to check safety, durability and compliance with relevant standards. Our accredited certifications, our recognition as a National High-Tech Enterprise in 2018, and the Eco-Functional Decorative (Sofa) Fabric Technology R&D Center certification awarded by the China Textile Engineering Society in 2025 are documented on our About Us page.
When you request a report from any supplier, including us, be specific. Name the series and article number, the colors you plan to buy and the market where the sofa will be sold. That lets the supplier send the relevant tests instead of a generic file. You can browse our six series to find the article first:
- Textured Velvet
- Artistic Velvet
- Versa Print
- Tech Leather & Fabric
- Modern Textured Fabric
- Fiber Artistry Fabric
The intended end use also changes which results deserve the most weight. Our application page covers home furnishing as well as office sofas, chairs and cushions. A residential sofa and an office seat do not need the same abrasion target.
Frequently asked questions
Is a higher Martindale number always better?
Not automatically. Beyond a certain point extra durability gains little for a home sofa, while a very stiff, tightly built fabric may feel less comfortable. Match the number to the use, and check pilling and appearance, not only breakage.
Can I compare a Martindale report with a Wyzenbeek report?
No. They are different methods with different failure rules. Ask for the method your market or customer expects.
Does a pass on one lot guarantee the next lot?
No. Reports describe the sample tested. For large orders, agree on lot-by-lot or pre-shipment testing in the contract.
Who decides pass or fail?
Either a legal requirement of the destination market or the specification you give the supplier. If neither exists, the lab simply reports numbers, and the judgment is yours.
How can I verify a report is genuine?
Contact the issuing laboratory with the report number and ask it to confirm the file. Many labs offer online verification or will confirm by email.
