It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Apparatus and Materials 6.

No universal standard fabric is available. The pilling resistance of a specific fabric in actual wear varies more with general conditions of use and individual wearers than in replicate fabric specimens subjected to controlled laboratory tests. This experience should be borne in mind when adopting levels of acceptability for any series of standards.

Combining values from the two systems may result in non-conformance with the standard. The test results from the two laboratories should be compared using a statistical test for unpaired data, at a probability level chosen prior to the testing series.

Testing before refurbishing may be adviseable. The visual standards are most advantageous when the laboratory test specimens correlate closely in appearance with worn fabrics and show a similar ratio of pills to fuzz.

A series of standards, based on graduated degrees of surface change of the fabric type being tested, may be set up to provide a basis for subjective ratings. Compare data from each shipment to avert problems.

With 2 or 4 pilling test chambers. To cope with this problem in the laboratory, make a subsequent test using the used liner surface on which the silicone-treated fabric was tested with a standard in-house fabric of known pilling history.

The visual standards are most advantageous when the laboratory test specimens correlate closely in appearance with worn fabrics and show a similar ratio of pills to fuzz. The development of pills may be accompanied by other astj phenomena such as loss of cover, color change, or the development of fuzz. Originally approved in Apparatus and d312 for visual evaluation are listed in Table 1. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every?

Summary of Test Method 4. Both results should be reported. Since the overall acceptability of a speci?

Pilling Resistance Testing of Textile Fabrics Using ASTM and AATCC

Always use the same weight and plane angle. If a bias is found, either its cause must be found and corrected, or future test results must be adjusted in consideration of the known bias. The test results showed that those fabrics with average ratings less than or equal to 2. Pills are caused to form on fabric by a random rubbing action produced by tumbling specimens in a cylindrical test chamber lined with a mildly abrasive material. Discard these and repeat the test with x3512 specimens.

The development of pills may be accompanied by other surface phenomena such as loss of cover, color change, or the development of fuzz.

The observed resistance to pilling is reported on an arbitrary scale ranging wstm 5 no pilling to 1 very severe pilling. Within the text, the inch-pound units are to be regarded as the standard. Avoid areas with wrinkles and other distortions.

Cotton sliver is available commercially. Link to Active This link will always route to the current Active version of the standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.

ASTM D3512 Random tumble pilling tester-fabric propensity to pilling

Other materials with established test values may be used for this purpose. Laboratory standard compressed air supply required. Describe the material or product sampled and the method of sampling used. Selection, Number, and Preparation 9. Random Tumble Pilling Tester. Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility. Random Tumble Pilling Tester uses stainless steel impellers rotate within individually lit aluminium chambers constantly tumbling test fabrics against cork liners for a pre-determined time controlled by a timer and audible alarm.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. If a bias is found, either its cause must be d512 and corrected, or future test results must v3512 adjusted in consideration of the known bias. Check, asym, when test results appear questionable, or following a change in test equipment adtm as the use of a new shipment of cork liners.

NOTE 5—If there is not sufficient material to provide three standard-size specimens, run with the available number of specimens rather than adding a specimen from another fabric, since there may be a strong interaction between fabrics which will create misleading results.

If it is used for acceptance testing, it d312 be used with caution because the between-laboratory precision is poor. Other materials with established test values may be used for this purpose. Store liners in original packaging in a cool, dry place.
