Описание (английский):

This part of ISO 12947 is applicable to the determination of the mass loss of specimens covering all textile fabrics including nonwovens apart from fabrics where the specifier indicates the end performance as having a low abrasion wear life. NOTE Further introductory comments are given in ISO 12947-1.

Overview

ISO 12947-3:1998 specifies a laboratory method for measuring the abrasion resistance of textile fabrics by the Martindale method using mass loss as the evaluation criterion. It applies to most textile fabrics including nonwovens (except when the specifier expects a deliberately low abrasion life). The procedure complements ISO 12947-1 (apparatus) and ISO 12947-2 (breakdown determination).

Key topics and technical requirements

Principle: Circular fabric specimens are rubbed against a standard abradant in a translational Lissajous motion while the specimen holder rotates. Abrasion resistance is determined from the mass loss of specimens.

Apparatus & materials: Uses the Martindale abrasion tester (see ISO 12947-1) plus a balance accurate to 1 mg. Standard abradant, felt underlay and foam backing dimensions are specified.

Loading: Two nominal loading conditions are defined to represent different end uses (nominal pressures ~12 kPa and ~9 kPa).

Specimens & dimensions:

Test specimen diameter: 38 mm
Abradant and felt substrate: at least 140 mm diameter (or length/width)
Foam backing: 38 mm diameter where required
Fabrics > 500 g/m² are usually tested without foam backing; pile and cord fabrics require special preparatory steps (Annex A).

Conditioning & atmosphere: Standard textile atmosphere per ISO 139 (20 ± 2 °C, 65 ± 5 % RH).

Test procedure:

Sample selection and conditioning per ISO 2859-1 and ISO 12947 parts.
Preselect rub-count intervals (Table 1) according to expected wear life (e.g., 100–125 000 rub cycles depending on category).
After abrading, remove debris with a soft brush, recondition, and weigh to 1 mg to determine mass loss.

Results & reporting: Calculate mean mass loss, standard deviation, confidence limits and variation coefficient. Produce a mass-loss vs. rub-count graph (abrasion index). Test reports must reference ISO 12947-3 and include specimen details, test series, preparatory treatments and any departures from the procedure.

Applications and users

Textile manufacturers and converters for product development and durability benchmarking

Quality control and inspection labs for acceptance testing of apparel, upholstery, workwear and technical textiles

Specifiers and purchasers to define abrasion performance requirements in contracts

Research and R&D teams comparing finishes, yarns or constructions

Common uses: product specification, supplier comparison, durability claims validation and failure analysis.
