(Practice)Standard Practice for Testing Chemical-Resistant Broadcast and Slurry-Broadcast Resin Monolithic Floor Surfacings
Standard Practice for Testing Chemical-Resistant Broadcast and Slurry-Broadcast Resin Monolithic Floor Surfacings
SIGNIFICANCE AND USE
Because the sample is prepared in a manner as it would be applied in the field, the test specimens may be considered representative of the application of a specified surfacing. Such methods include application by squeegees, rollers, trowels, notched trowels, and gage rakes.
These systems vary in several ways, including the number of layers or application steps, the surface finish, and variation in composition.
The results obtained in carrying out this practice should serve as a guide in comparing similarly applied surfacings. No attempt has been made to incorporate into this practice all of the various factors that may affect the performance of such applications when subjected to actual service.
SCOPE
1.1 This practice covers methods for preparing test specimens and testing procedures for broadcast or slurry-broadcast monolithic floor surfacings in areas where chemical resistance is required.
1.2 These floor surfacings are applied by various application methods including squeegees, rollers, trowels, notched trowels, and gage rakes onto suitably prepared concrete substrates. The surfacings bond to the substrate upon curing to provide a nominal thickness of 60 mils (1.5 mm) or greater.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
