ASTM C1559-15

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

SIGNIFICANCE AND USE
5.1 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, fibrous glass blanket insulation to wick water.  
1.2 The wicking characteristics of materials can be affected by environmental conditions such as temperature and humidity. Values obtained as a result of this test method does not adequately describe the wicking characteristics of materials subject to conditions other than those indicated in the test method. (See Specification C800.)  
1.3 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.  
1.4 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.
