ASTM C1511-15

Standard Test Method for Determining the Water Retention (Repellency) Characteristics of Fibrous Glass Insulation (Aircraft Type)

SIGNIFICANCE AND USE
5.1 The water retention of the insulation 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 water absorption potential of blanket insulation for aircraft, thereby providing a measure of potential weight increase due to water retention in an aircraft.  
1.2 The water repellency (or retention) characteristics of materials can be affected by conditions such as contamination or temperature of the water. Values obtained as a result of this test method does not adequately describe the water repellency characteristics of materials subject to these conditions.  
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.

8.1 No conditioning of the specimen is required.
9. Procedure
9.1 Weigh each specimen to the nearest 0.1 g.
9.2 Float each specimen on the surface of a vat of de-ionized (or distilled) water at 70 6 4°F (21 6 2°C). Lay a 0.25-in.
(6.4-mm) mesh rigid screen on top of each specimen and slowly submerge it to a level that is 5 in. (127 mm) below the surface
