ASTM C1511-01

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

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 may be affected by conditions such as contamination or temperature of the water. Values obtained as a result of this test method may not adequately describe the water repellency characteristics of materials subject to these conditions.
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.
