1、Designation: D 1792 06Standard Test Method forLong-Term Removability Properties of Emulsion FloorPolishes1This standard is issued under the fixed designation D 1792; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last
2、revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This test method covers the determination of the relativeease of removal of dried films of water-emulsion floor polishesfr

Summary of Test Method3.1 The dried films are conditioned at 37.8C (100
5、F) inorder to simulate service aging. This method utilizes theGardner straight-line washability apparatus as a means forcontrolled removal of the dried films. A heavily weighted padis employed as a means of arriving at a scrubbing force similarto that of hand scrubbing. In order to distinguish betwe

Significance and Use4.1 This test method is used to predict removability of floorpolish after a treatment period that simulates aging in the field.
