ASTM D1151-2000(2006) Standard Practice for Effect of Moisture and Temperature on Adhesive Bonds《潮气和温度对胶粘剂粘结能力影响的标准方法》.pdf

1、Designation: D 1151 00 (Reapproved 2006)Standard Practice forEffect of Moisture and Temperature on Adhesive Bonds1This standard is issued under the fixed designation D 1151; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year

2、of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) 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

3、for 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

4、to 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

5、 health practices and determine the applica-bility of regulatory limitations prior to use.2.

Apparatus5.1 Conditioning Cabinets or Ovens, with temperature andhumidity control.6. Test Specimens6.1 Prepare the test specimens in accordance with therecommendations of the manuf

9、acturer 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 AST

Procedure8.1 Test the control specimens for strength by the appropri-ate test method immediately after the preconditioning period.Average the values obtained. Record this average as theoriginal strength agai

15、nst which the strength after exposure is tobe compared in calculating performance.8.2 Subject the preconditioned specimens to the designatedexposure conditions (Table 1) for the length of time prescribedby the specification for the adhesive being tested. At the end ofthe exposure period, test the sp

16、ecimens using one of thefollowing procedures:8.2.1 Test the specimens under conditions at which theywere exposed, or8.2.2 Condition the specimens for4hat506 2 % relativehumidity and 23 6 1C (73.4 6 1.8F) and test immediatelythereafter, or8.2.3 Condition the specimens for 7 days at 50 6 2%relative hu

17、midity and 23 6 1C (73.4 6 1.8F) and testimmediately thereafter.8.3 Average the strength values obtained and record thevalue as the average strength of the specimens after exposure.NOTE 1The conditions under which the exposed specimens are testedwill depend upon the nature of the adhesive, the adher

18、end, and the strengthproperty being investigated. This will be prescribed by the materialspecifications or by written agreement between the manufacturer andpurchaser of the adhesive.9. Calculation9.1 Calculate the performance of the adhesive under test, asfollows:Performance A 5 A/D! 3 100, (1)Perfo

19、rmance B 5 B/D! 3 100, (2)orPerformance C 5 C/D! 3 100.
