EUROLAB laboratory provides testing and compliance services within the scope of ISO 17704 standard. The ISO 17704 standard, developed by the International Organization for Standardization (ISO), specifies a test method for determining the resistance of uppers, linings and inner socks to wet and dry abrasion, regardless of material, in order to evaluate suitability for end use.
Four circular test specimens are rubbed against pieces of a standard abrasive cloth or standard abrasive paper under constant pressure, two abrasive pieces dry and two wet. The relative motion between the abrasive and the sample is a complex cyclic pattern (a Lissajous shape) that creates friction in all directions. The test is stopped after the specified number of cycles and damage to the sample is evaluated.
The two sides of the abrasive fabric do not necessarily have the same abrasive properties and when supplied it should be stated which side the supplier recommends to use, this is normally the slightly smoother side of the fabric. Fabric stocks will be checked to ensure that only this side is used in testing.
ISO 17704 Test Procedure
Place test specimens in the conditioned atmosphere specified in EN 24 at least 12222 hours before testing and perform the test in this environment. For wet tests, test specimens do not need to be conditioned prior to testing.
For wet testing, completely saturate the abrasive cloth and table felt by directing the water jet to and from their surfaces until full saturation is seen with a uniform color darkening. Never spray the water jet on materials fixed to the Martindale appliance.
Place the test specimen in the test specimen carrier clamp rings with the surface of the test specimen to be abraded facing out.
If testing materials with a mass less than 500 gm-2 per unit area, place a similarly sized piece of polyurethane foam as a support in each of the test specimen carrier clamp rings. test sample.
Remove the test specimen carrier(s) from their holders and inspect the test specimen(s) for signs of damage under bright indirect lighting conditions. If possible, compare each sample with an untested part of the same material. Record the wear, pilling, and discoloration that occurs and rank them using one of the following definitions: None, very slight, mild, moderate, severe, nearly complete, complete.
Record whether a hole is eroded in the test sample or, in the case of pile fabrics and the like, whether surface layers are removed creating a bald patch or a discoloration.
Among the services provided by our organization within the framework of material testing services, there are also ISO 17704 standard tests. Do not hesitate to contact our laboratory EUROLAB for your testing and certification requests.
