Avoid areas with wrinkles and other distortions. For fabric components of fabricated systems use the entire system. China bert tester China main tester China benz tester. OEM is also acceptable for us. These factors are not evaluated when pilling is rated solely on the number of pills. The pilling resistance of a speci? The test results showed that those fabrics with average ratings less than or equal to 2. Firmly grasp the specimen by a corner and allow the vacuum suction to draw the specimen inside.
Each test facility must decide d312 an appropriate fabric. There is no independent, referee method by which bias may be determined. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every? To eliminate any tendency for the liner to rotate, tape the outside edge of the liner to sstm chamber wall at the butt joint with a short piece of mm 1-in.

Tests run with one or two specimens, while not strictly comparable with standard tests, are considered more indicative than tests that include more than one fabric type. Cotton sliver is available commercially.
The observed resistance to pilling is reported on an arbitrary scale ranging from 5 no pilling to 1 very severe pilling. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the d35112.
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. Since the overall acceptability of a specific fabric is dependent on both the characteristics of the pills and the other factors affecting surface appearance, it is suggested that fabrics tested in the laboratory be evaluated subjectively with regard to their acceptability and not rated solely on the number of pills developed.

NOTE 4—Although the use of glued or not glued specimens is acceptable, the measurements should not be compared. Within the text, the inch-pound units are shown in parentheses. This experience should be borne in mind when adopting levels of acceptability for any series of standards. The degree of fabric pilling is evaluated by comparison of the tested specimens with visual standards that may be actual fabrics, or photographs of fabrics, showing a range of pilling resistance.
