1、Designation: D1151 00 (Reapproved 2013)Standard Practice forEffect of Moisture and Temperature on Adhesive Bonds1This standard is issued under the fixed designation D1151; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of
2、 last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1. Scope1.1 This practice defines conditions for
3、 determining theperformance of adhesive bonds when subjected to continuousexposure at specified conditions of moisture and temperature.The performance is expressed as a percentage based on theratio of strength retained after exposure to the original strength.1.2 The values stated in SI units are to
4、be regarded as thestandard. The values given in parentheses are provided forinformation purposes only.1.3 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and he

Test conditions of temperature and moistureonly are here specified. The duration of exposure is dependentupon th
8、e nature of the adhesive and the type of specimens andwill, therefore, be covered by material specifications.5. Apparatus5.1 Conditioning Cabinets or Ovens, with temperature andhumidity control.6. Test Specimens6.1 Prepare the test specimens in accordance with therecommendations of the manufacturer
9、of the adhesive. Thespecimens should be of a suitable form and number to meet therequirements of the investigation. The specimens should con-form in detail with the requirements prescribed in the ASTMtest method covering the desired strength property, as listed inSection 2, and any other ASTM test m
