ISO 12947-2 Martindale Abrasion Tester | Fabric Abrasion Resistance Machine - UnitedTest
UnitedTest manufactures ISO 12947-2 Martindale abrasion testing machines for textile fabric abrasion resistance, measuring rub cycles until specimen breakdown for woven, knitted, pile, flocked and nonwoven textiles.
ISO 12947-2 specifies the Martindale method for determining textile fabric abrasion resistance by counting abrasion cycles before specimen breakdown. A circular fabric sample is clamped under specified load and rubbed against standard wool abradant following a Lissajous motion path. Clear failure criteria are defined: two broken threads for woven fabrics, one broken thread for knits, complete wear for pile and flocked fabrics, and a minimum 2.5 mm hole for nonwovens, delivering repeatable, lab-comparable results widely used for upholstery and contract textile durability requirements.
Core Test purpose / principle
A circular specimen is mounted in a specimen holder, placed under a defined load, and rubbed against an abrasive medium (standard woven wool abradant) in a translational movement tracing a Lissajous figure; the holder is additionally free to rotate about its own axis perpendicular to the specimen plane. Abrasion resistance is derived from the inspection interval at which breakdown of the specimen is observed.
Key rules of the principle:
Specimens are mounted with foam backing; specimens of ≥500 g/m² are mounted without foam.
Pile fabrics tested without foam receive a specified preparatory treatment (7.5.2).
The number of rubs recorded is the last interval at which breakdown was not yet observed — i.e. the upper limit of the pre-breakdown period and the lower limit of the breakdown interval.
Testing continues up to breakdown.

Test Procedures for ISO 12947-2 Fabric Breakdown Abrasion Testing
Mount abradant and wool felt centrally on each abrading table, secured by clamping ring after compression using the 2.5 kg pressing weight; check no cut edges sit inside the clamping‑ring working area.
Mount prepared specimen in specimen holder (wear‑side down). Fit foam backing for fabrics ≤ 2500 g/m². Tighten holder assembly; visually verify central positioning with no cut edges exposed in the holder aperture. Remount if mis‑aligned.
Install specimen holders to machine spindles, fit the required loading weights, start abrasion cycles according to the chosen interval sequence.
Stop the machine upon completion of each interval. Remove holders, gently blow or softly brush loose fibre debris without damaging specimen yarns; do not remove pills. Inspect for specimen breakdown using magnifier and template as required. Record visible intermediate changes (partial pile wear, loop damage, colour change assessed at 6 000 rubs per ISO 105‑A02 if needed) and corresponding rub count. If no breakdown, reassemble and resume testing.
Stop test when breakdown criterion is met for a specimen, or upon pre‑agreed maximum rub limit. Record for each specimen the rub number of the last interval before breakdown was observed. The quoted final test result is the lowest individual value among replicate specimens.
Complete the formal test report covering standard reference, sample description, applied load/pressure, pre‑treatments, backing‑foam usage, fabric type and endpoint criteria, individual results, reported final value, observed visual changes, deviations from procedure and stopping‑limit information.

Why This Test Matters for the Material
Abrasion is the dominant in-service failure mode. Seats, cuffs, collars and heavy-traffic surfaces rarely fail by tearing; they fail by progressive surface wear — yarn rupture, pile flattening/denudation, hole formation. Martindale reproduces that mechanism in a controlled, multi-directional way (Lissajous motion ≈ real multi-directional rubbing, unlike a linear rub test).
It converts "durability" into an objective, comparable number. Because the end-point is defined inside the standard (thread count, worn-off area, hole size) rather than by subjective judgement, two laboratories can produce comparable results — essential for tenders, certifications and supply contracts (e.g. EN 14465 / DGM ≥30 000 cycles) .
It is a material-development tool. The rub count directly reflects fibre type, yarn twist/linear density, weave/knit construction, fabric mass, pile height, finishes and coatings — so it lets mills and brands compare constructions, blends and finishing routes quantitatively before committing to production.
It de-risks specification and warranty. Under-specifying leads to premature wear, complaints and claims; over-specifying inflates cost and weight. Martindale data let specifiers match duty class (domestic → severe contract) to the right fabric.
It protects brand and compliance. Procurement specs, retailer requirements and furniture quality marks almost always name a Martindale figure; a documented ISO 12947-2 certificate is the evidence

FAQs for ISO 12947-2 (Martindale Abrasion Test, Specimen Breakdown)
Q1: What is ISO 12947-2 test?
A1: ISO 12947-2 is a Martindale abrasion test method that counts abrasion cycles until the test specimen reaches the breakdown endpoint (thread rupture). It is different from mass loss (ISO 12947-3) or appearance change evaluation (ISO 12947-4). It uses the Martindale machine defined in ISO 12947-1 to perform Lissajous-pattern rubbing under specified load.
Q2: Why is ISO 12947-2 important for textile materials?
A2: It gives a clear failure threshold instead of only weight loss or visual scoring. Manufacturers can verify whether upholstery, apparel, automotive textiles and home fabrics will develop holes or broken threads under repeated friction during real use. It supports product specification, buyer approval, quality control and compliance with tender or certification requirements, and reduces after-sale complaints about premature fabric perforation.
Q3: What is the pass/fail endpoint for ISO 12947-2?
A3: The test stops when the specified breakdown criterion occurs: normally when two or more warp or weft threads are broken through the specimen surface. The result is reported as the number of rub cycles at breakdown. Inspection is done at preset cycle intervals, not only at the final run.
Q4: What is the difference between ISO 12947-1 and ISO 12947-2?
A4: ISO 12947-1 defines the hardware: Martindale tester structure, holders, abradant, dimensions and loading requirements. ISO 12947-2 defines the test procedure, conditioning, inspection rules and breakdown evaluation method using that apparatus. ISO 12947-1 is the machine standard; ISO 12947-2 is the test method for specimen failure.
Q5. Why is a Lissajous (figure-of-eight-like) motion used instead of a straight back-and-forth rub?
A5: Real wear on a garment or a seat is multi-directional. The Lissajous path constantly changes abrasion direction relative to warp, weft and pile, so it reproduces in-service wear far better than a single-direction linear rub.
Q6: What test load and stroke length apply to ISO 12947-2?
A6: Common standard load is 12 kPa on the specimen. The Martindale runs with a 60 mm Lissajous stroke path. Load can be adjusted according to fabric type and buyer specification, but the breakdown judging rule follows Part 2 strictly.
Q7: What specimens and abradant are used?
A7: Circular fabric specimens are cut from production rolls, conditioned in standard atmosphere (ISO 139). The rubbing abradant is standard worsted wool fabric. Multiple replicate specimens are required to calculate the average breakdown cycle count.
Q8: Can ISO 12947-2 test leather, coated fabric or nonwoven?
A8: ISO 12947 series is originally for textile fabrics. Coated fabrics and heavy nonwovens may be tested if they fit the holder and do not damage the machine. For leather abrasion, ISO 17076-2 (leather Martindale) is the dedicated standard.
Q9: Why might two labs get different ISO 12947-2 results on the same fabric?
A9: Main influence factors: conditioning humidity/temperature, abradant ageing or contamination, operator judgement of broken threads, interval setting for inspection, specimen orientation (warp vs weft), and uneven fabric structure. Calibration of the Martindale load and movement also affects repeatability.
Q10: Is a higher cycle number always better?
A10: Only when tested under identical load, abradant and endpoint rule (breakdown per ISO 12947-2). A high Martindale count means higher resistance to hole formation, but it cannot directly equal real service life without matching end-use friction conditions.
Q11: Does ISO 12947-2 cover pilling?
A11: No. ISO 12947-2 only measures abrasion until thread breakage. Pilling evaluation follows ISO 12945-2, which uses shorter stroke and different assessment criteria. Many combined Martindale testers support both standards, but they are separate test protocols.
Q12. How are stretch fabrics handled?
A12: Suspect stretch fabrics (e.g. containing elastane) are cut to 60 mm × 60 mm squares, mounted on the (45.0 ± 0.1) mm square table of the stretch-fabric device with 4 × (100 ± 2.5) g masses (total 400 ± 10 g), loaded by lowering the bracket three times, then bonded to a ~50 mm PVC film (≈0.2 mm) with a central 30 mm hole. A Ø38 mm specimen is then stamped so a 4 mm film ring keeps it lightly extended, and it is mounted immediately.
Q13. Can Martindale rubs be converted into Wyzenbeek double rubs?
A13: No. The abradants, the motion (multi-directional Lissajous vs. linear along warp/weft), the loads and the end-points all differ. Industry bodies (e.g. ACT) state plainly that there is no correlation between the two; the commonly circulated "1 double rub ≈ 2 Martindale rubs" ratio has no scientific basis. Always compare like with like, and name the method in the specification.
