The values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other. The procedure is generally applicable to all types of woven and knitted apparel fabrics.
Compare data from each shipment to avert problems. As a minimum, the test samples should be used that are as homogeneous as possible, drawn from the material from which the disparate test results were obtained, and randomly assigned in equal numbers to each laboratory for testing.
Specimens should be staggered in such a manner that no two specimens contain the d35512 yarns.
Combining values from the two systems may result in non-conformance with the standard. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. To eliminate any tendency for the liner to rotate, tape the outside edge of the liner to the chamber wall at the butt joint with a short piece of mm 1-in.
Summary of Test Method 4.
Preparation of Apparatus NOTE 7—Depending on the nature of the material under test, running times of other than 30 min may be more appropriate for evaluating the pilling tendencies of fabrics; for example, min intervals up to 30 min may be more indicative for certain knit or soft-woven fabrics.
China tester tool China a. Check, also, when test results appear questionable, or following a change in test equipment such as the use of a new shipment of cork liners.

Apparatus and options for visual evaluation are listed in Table 1. Strips indicate that different yarns may have been used in making the fabric being tested. Your comments will receive e3512 consideration at a meeting of the responsible technical committee, which you may attend. Allow the chamber to dry before the next use.
To cope with this problem in the laboratory, make a subsequent test using the used liner adtm on which the silicone-treated fabric was tested with a standard in-house fabric of known pilling history.
D35112 sliver is available commercially. These factors are not evaluated when pilling is rated solely on the number of pills. Pressing the adhesive into the specimen face may be accomplished using the dispensing nozzle in a closed con?

The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. This experience should be borne in mind when adopting awtm of acceptability for any series of standards. To form pills with appearance and adtm that resemble those produced in actual wear, small amounts of short-length gray cotton? 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 aetm audible alarm.
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. Store the fabric rating standards and handle them under conditions that will preserve their original form and appearance.
