EN 12945-2:2020

A circular test piece on a rubbing surface made of the same fabric or, if necessary, of an abrasive wool fabric, is subjected to a defined force by describing a Lissajous curve with the test piece, capable of easily rotating around an axis that passes through its center, perpendicular to the plane of the specimen. Fuzz and pilling are evaluated visually after the defined steps in the test.

Martindale Abrasion Testing Machine according to ISO 12947-1

• Plates for the formation of small balls
• Counter
• Specimen holder guide plate
• Specimen holder
• Load pieces (415g or 155g depending on test category)
• Auxiliary device for placing the specimen
• Load for placing the specimen on the plate for the formation of balls,
• Observation cabin
• Rubbing fabric
• Wool abrasive fabric specified in ISO 12947-1.

• The specimen to be placed in the specimen holder must be a disk of (140+5) mm in diameter. The test piece to be placed in the ball-forming plate can be (140+5) mm in diameter or (150 ± 2) mm in length and width, depending on the case.
• A minimum of three sets of complete test tubes are necessary, since a complete set includes a test tube for the test tube holder and a test tube for the plate for the formation of pellets; also an additional test tube for comparative evaluation. In case of using the wool rubbing cloth on the pellet formation plate, at least three test tubes of the fabric under test are necessary for the test tube holders.
• Conditioning: 16 h ISO 139
• The sample can be tested in its original state or after its pre-treatment.
