1、Designation: D1183 03 (Reapproved 2011)Standard Practices forResistance of Adhesives to Cyclic Laboratory AgingConditions1This standard is issued under the fixed designation D1183; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, th
2、e year of 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 These practices cover the d
3、etermination of the resistanceof adhesives to cyclic accelerated service conditions by expos-ing bonded specimens to conditions of high and low tempera-tures and high and low relative humidities. The extent ofdegradation is determined from changes in strength propertiesas a result of exposure to the
4、 test conditions (Note 1). It isrecognized that no accelerated procedure for degrading mate-rials correlates perfectly with actual service conditions, andthat no single or small group of laboratory test conditions willsimulate all actual service conditions. Consequently, care mustbe exercised in the
5、 interpretation and use of data obtained inthis practice. The test condition, the number of cycles of thetest condition to be used, the particular strength property to beused to determine the extent of degradation, and whether testspecimens or test panels are to be used, is specified in thematerial
6、specification.NOTE 1These practices/conditions are intended for use with speci-mens described in the approvedASTM strength test methods for adhesivesas follows:Test Methods D897, D903, D906, D950, D1002, D1062, and MethodD1344.1.2 The values stated in SI units are to be regarded as thestandard.1.3 T

Procedure8.1 Subject specimens or panels to the number of cycles ofone of the test conditions listed in Table 1, as specified in thematerial specifications.8.2 Place the specimens or panels in the containers so thatfree access of the c
19、ontrolled atmosphere is obtained for at least75 % of the total area of each test specimen or panel.8.3 After completion of the exposure of the test specimensor panels to one of the test conditions in Table 1, condition thetest specimens or panels for 7 days at a relative humidity of50%at236 1C (73.4
20、 6 2F) and then test them immediatelyfor the specified strength properties, unless otherwise stated inthe material specifications.9. Calculations9.1 The average strength value determined in accordancewith the designated method of test is used to calculate thechange in strength, as follows:R 5 Y 2 X!
21、/X 3 100 (1)where:R = percent change in strength as a result of exposure to thetest conditions,X = initial strength, andY = strength after exposure to the test conditions.The sign of the result will indicate whether there is a gain( + ) or loss () in strength.9.2 Specimens or panels that delaminate
22、during the testshave a change in strength of 100 %. Specimens that delami-nate during the tests before the strength test can be made havea strength of 0, included in calculating the average strength andstandard deviation.10.
