AATCC EP-5-2007 Fabric Hand: Guidelines for the Subjective Evaluation of Developed in 1990 by AATCC Committee R 2006; revised 1996 (with title change); A89; reaffirmed 1991, 1992, editorially revised 1997; editorially re- vised and reaffirmed 2001. 3. Terminology impressions which arise when fabrics are 3.1 hand, n.—the tactile sensations or touched, squeezed, rubbed or otherwise handled. 3.2 constituent elements of hand, n.—those components, qualities, attributes, dimensions, properties or im- pressions which make the sensation of touching one fabric different from that of touching another. elements of hand can be categorized NOTE: The various terms comprising by physical attributes of compression, bending, shearing and surface (see Ap- pendix A). 4. Uses and Limitations 4.1 Effective use of these guidelines is limited by the ability of the evaluator to describe the sensations being felt. Care should be taken to determine if any eval- uator exhibits impairment in touch and to determine if any variation between evalu- ators exists. will be dependent on prior agreement re 4.2 The validity of the data collected 382 EP 5 garding which constituent elements of hand are to be evaluated and mutual acceptance of a scale for evaluation. 5. Specimens 5.1 Test Specimens. 5.1.1 Take large enough test specimens from each sample to allow an evaluator to general, cut all specimens to greater than hold the specimen in both hands. In 200 mm (8 in.) and less than 900 mm (35.4 tion. All specimens are to be cut to the in.) in either length or width direcsame size and shape, even if ratings are done at different times/dates. 5.1.2 Identify the length and width di- rection of each specimen to provide a means to assess differences that may exist. 5.1.3 Avoid using a specimen more than one time for evaluation because stretching and crushing may change the fabric hand. 5.1.4 The number of specimens of each sample used is to be consistent with accepted statistical analysis and with the number of evaluators. 5.2 Specimen Marking. uation, specimens are to be prepared 5.2.1 Prior to conditioning and eval- and marked by someone other than the evaluator. 5.2.2 Mark specimens to denote sample and specimen identification, the surface of the specimen to be evaluated and the length direction of the fabric (see 5.1.2). Use a pen or pencil, not attached labels, to mark the specimens with identification, directional and surface information. 5.2.3 Condition specimens from the dry side for...
