ASTM C1559-04

Standard Test Method for Determining Wicking of Glass Fiber Blanket Insulation (Aircraft Type)

SIGNIFICANCE AND USE
The tendency of the insulation toward wicking can result in an increase in weight and a resultant potential degradation in the properties of the insulation.
SCOPE
1.1 This test method covers a laboratory procedure for evaluating the tendency of, aircraft type, glass fiber blanket insulation to wick water.
1.2 The wicking characteristics of materials may be affected by environmental conditions such as temperature and humidity. Values obtained as a result of this test method may not adequately describe the wicking characteristics of materials subject to conditions other than those indicated in the test method.
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.

12. Calculation or Interpretation of Results
12.1 Determine the amount of wicking by measurement
with a steel rule as described in 6.2.
12.2 Wetting of the submerged portion of the wicking
specimens is permissible. Wicking is the distance of wetting
above the water surface (average value of center-point mea-
surements of three sides of the wicking specimen-side adjacent
to screen surface should not be measured).
