Abstract
This test method covers the determination of the efficiency of ordinary commercial wetting agents using the skein test. It is applicable under limited and controlled conditions, but does not necessarily yield information correlating with specific end uses. The apparatus is comprised of a hook of standard weight depending on the concentration of the wetting agents and an anchor which shall be a flat, cylindrical, lead slug of specific dimensions. The reagents shall consist of water, acid and base test solutions, and wetting agent. The average of at least four determinations of the sinking time for each concentration of wetting agent shall be obtained and presented in plots with logarithmic coordinates. Standard deviation based on six replicate determinations shall also be calculated for precision.
Scope
1.1 This test method , covers the determination of the efficiency of ordinary commercial wetting agents as defined in Terminology D459. This test method is applicable under limited and controlled conditions, but does not necessarily yield information correlating with specific end uses.
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
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.
