EDANA INDA Testing Standards for Nonwoven Fabric: Methods, Properties and Units — India Supplier Guide
EDANA and INDA testing standards are the globally recognised test method frameworks for nonwoven fabric characterisation. Favourite Fab, a B2B nonwoven fabric raw material supplier based in Agra, India, references EDANA and INDA methods in all technical data sheets (TDS) and quality certificates. This guide explains key EDANA and INDA test methods, the properties they measure, units, and testing frequency — helping procurement managers and quality engineers align incoming inspection with supplier test methods.
What Are EDANA and INDA Nonwoven Testing Standards
EDANA (European Disposables and Nonwovens Association) and INDA (Association of the Nonwoven Fabrics Industry, North America) jointly publish the EDANA/INDA Nonwoven Standard Procedures (ISP). These are the most widely used test method standards in the global nonwoven industry, covering physical, mechanical, absorbency, and chemical properties. EDANA methods use the format ERT (EDANA Recommended Test); INDA methods use WSP (Worldwide Strategic Partners) numbering — e.g. WSP 40.3 for basis weight.
Key EDANA INDA Test Methods for Nonwoven Fabric
| Method Code | Property | Unit | Frequency |
|---|---|---|---|
| ERT 40.3 / WSP 40.3 | Basis weight (GSM) | g/m² | Every roll — 100% inspection |
| ERT 20.2 / WSP 110.4 | Tensile strength and elongation MD/CD | N/5cm, % | Per batch minimum |
| ERT 30.5 / WSP 120.6 | Thickness under specified pressure | mm | Per batch |
| ERT 10.1 / WSP 10.1 | Sink time (absorbency) | seconds | Per batch — hydrophilic grades |
| ERT 140.1 / WSP 70.1 | Air permeability | mm/s | Per batch |
| ERT 50.2 / WSP 80.9 | Hydrostatic head (water repellency) | mbar | Per batch — barrier grades |
| ERT 120.1 / WSP 210.1 | Burst strength (Mullen test) | kPa | Per batch — medical/filter grades |
| ERT 150.3 / WSP 90.1 | Pilling resistance | Grade 1–5 | On buyer request |
Why EDANA INDA Standards Matter for Manufacturers
Using a common test method framework ensures that property values on a TDS mean the same thing to every buyer and supplier. A tensile strength value tested to ERT 20.2 is directly comparable across different nonwoven suppliers — sample size, grip distance, test speed, and conditioning are all defined by the standard. Without method alignment, buyers cannot meaningfully compare competing fabric samples.
For hygiene product manufacturers (sanitary pad, baby diaper, adult incontinence), EDANA methods are the de facto industry standard. For medical device OEMs sourcing nonwoven for surgical gowns or drapes, EN 13795 harmonised test methods are used alongside EDANA procedures. Favourite Fab’s QC lab runs routine EDANA/WSP testing and can provide test certificates aligned to either framework.
EDANA vs INDA vs ISO: Which Standard to Specify
EDANA ERT and INDA WSP methods are largely harmonised — they test the same properties with closely aligned procedures. ISO 9073 is the international standard series for nonwoven test methods, which shares significant technical overlap with EDANA/WSP. European buyers typically specify EDANA/EN; North American buyers specify INDA/ASTM; global buyers increasingly use ISO 9073 for neutrality. Favourite Fab can provide TDS with any of these method references — specify your preference at the quotation stage.

Frequently Asked Questions
Q: What is the difference between EDANA and INDA nonwoven test standards?
A: EDANA (European) and INDA (North American) are sister organisations that jointly publish the WSP (Worldwide Strategic Partners) nonwoven test procedures. The methods are technically harmonised — EDANA ERT and INDA WSP measure the same properties using equivalent procedures. European suppliers typically reference EDANA codes; North American suppliers reference INDA/WSP codes.
Q: Which EDANA test method measures GSM of nonwoven fabric?
A: Basis weight (GSM) is measured per EDANA ERT 40.3 (also published as WSP 40.3). The method specifies sample size (100 cm² minimum), conditioning (standard atmosphere 23°C / 50% RH), and calculation procedure. Favourite Fab tests GSM on every roll as part of 100% outgoing inspection.
Q: Does Favourite Fab test tensile strength per EDANA ERT 20.2?
A: Yes. Tensile strength (MD and CD) and elongation at break are tested per EDANA ERT 20.2 / WSP 110.4. Strips of 50mm width are tested on a calibrated tensile testing machine at 100mm/min crosshead speed. Results are reported in N/5cm for tensile strength and % for elongation.
Q: Can I request absorbency testing per EDANA ERT 10.1 (sink time)?
A: Yes. Sink time (absorbency) testing per EDANA ERT 10.1 / WSP 10.1 is performed as standard for all hydrophilic nonwoven grades (topsheet, acquisition layer, spunlace). Results are reported in seconds. Hydrophilic grades from Favourite Fab typically achieve sink times well below 10 seconds.
Q: Are EDANA test methods accepted for medical device nonwoven qualification?
A: EDANA methods are widely accepted as the reference standard for nonwoven raw material characterisation in medical device applications. EN 13795 (surgical gowns and drapes) references specific test properties that align with EDANA methods. Favourite Fab can provide test certificates suitable for inclusion in technical files under MDR 2017/745.
