ASTM D1791-93(2008)

Standard Test Method for Accelerated Aging of Liquid Water-Emulsion Floor Polishes

SIGNIFICANCE AND USE
This test method is not absolute but does give an indication of the useful shelf-life of a liquid water-emulsion floor polish. Will indicate whether a polish will gel or remain a usable liquid over the desired storage life of the product. It should be noted that polishes of different composition types will vary in useful storage life under identical storage conditions.
SCOPE
1.1 This test method covers the storage stability of liquid water-emulsion floor polishes.
1.2 Storage for 30 days at 52°C (125°F), while not a guarantee of one year stability at 21°C (70°F), is believed to be a more reliable indicator of storage stability than similar tests of shorter duration.
Note 1—The 60° specular gloss on black glass determined by Test Method D 1455, may be used to confirm this observation. A substantial difference in gloss between aged and unaged samples is an indication of instability. A shelf stability of one year can be reasonably expected of the material in question if duplicate samples remain unchanged for 30 days at 52 ± 1.1°C (125 ± 2°F). If one or both duplicates show more than slight viscosity increases or slight creaming, other evidence of stability must be sought.  
1.3 This standard does not purport to address all of the safety problems, 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.
