1、Designation: D6540 17Standard Test Method forAccelerated Soiling of Pile Yarn Floor Covering1This standard is issued under the fixed designation D6540; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A nu
2、mber in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This test method describes the equipment, and the testmethod for assessing the propensity of pile yarn floor coveringsto soiling in the a
3、bsence of abrasive wear and texture changes,using a standard synthetic soil composition.1.2 This test method is applicable for use in testing unusedpile yarn floor covering of all types. It is not applicable for usein testing used pile yarn floor covering.1.3 This test method can be used to compare
4、the soilingpropensity of two or more carpets; or it can be used to soilcarpets as a preliminary step to other test procedures.1.4 The values stated in inch-pound units are to be regardedas standard. The values given in parentheses are mathematicalconversions to SI units that are provided for informa

Summary of Test Method4.1 The carpet test specimens are secured to a backing sheetthat is mounted inside the drum with the pile surface exposed,and are subj
10、ected to an accelerated soiling process. The degreeof soiling is measured or assessed by comparing the change incolor between soiled and original pile yarn floor covering,using a measurement device or visually matching the differ-ences on the light-dark axis of Gray Scales.NOTE 1Differentiation betw

Significance and Use5.1 This test method may be used to soil test specimens inthe absence of abrasive wear and texture changes undercontrolled conditions using a standard synthetic soil, or as apreliminary step to other procedures
12、.5.2 This test method will provide a uniformly soiled testspecimen to evaluate, is reproducible (see section 11), and iseconomical for Testing Laboratories.5.3 This test method has been found to give results similarto the actual floor service soiling, but its use is recommendedonly as a screening te
