    1、Designation: D1792 06 (Reapproved 2012)1Standard Test Method forLong-Term Removability Properties of Emulsion FloorPolishes1This standard is issued under the fixed designation D1792; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision,

    2、the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1NOTEEditorial changes were made in October 2012.1. Scope1.1 This test method covers the determination of the relative

    3、ease of removal of dried films of water-emulsion floor polishesfrom common flooring substrates under accelerated conditions,which correspond to extended service aging.1.2 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of

    4、the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2. Referenced Documents2.1 ASTM Standards:2D1436 Test Methods for Application of Emulsion FloorPolishes to Substrates for Testing Purposes3. Summary

    5、 of Test Method3.1 The dried films are conditioned at 37.8C (100F) 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

    6、 similarto that of hand scrubbing. In order to distinguish between therelative removal properties of different polishes, the number ofoscillations required for complete removal is taken as ameasure of removability.4. Significance and Use4.1 This test method is used to predict removability of floorpo

    7、lish after a treatment period that simulates aging in the field.It allows for uniform mechanical and detergent action leavingthe only variable the actual removability of the polish.5. Apparatus5.1 Volumetric Pipet, 1-mL, graduated in 0.2-mL units.5.2 ApplicatorDoctor blade 51 mm (2 in.) wide by 25 m
