(Test Method)Standard Test Method for Determining Wicking of Fibrous Glass Blanket Insulation (Aircraft Type)
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

11. Procedure C—Wicking after Leaching
11.1 Condition a sample of insulation 8- by 14-in. (203- by
356-mm) by submerging in an immersion tank of de-ionized
(or distilled) water maintained at a temperature of 80 to 85°F
(27 to 29°C) for a period of at least 24 h. The tank shall be of
such a shape and size that the specimen can be submerged
therein with all surfaces of the specimen having full access to
the water. Ratio of specimen to water shall not be less than 1
to 100 by weight.Acontinuous flow of water shall be supplied
to the bottom of the container at the above temperature at a rate
of five changes per hour.At the end of the leaching period, the
specimen shall be removed from the water, air dried to a
constant weight and weighed. The leached specimen shall be
tested according to procedure outlined in
9.2 – 9.5.
