ASTM D903:98(R2017) pdf free download – Standard Test Method for Peel or Stripping Strength of Adhesive Bonds.
Adjust the autographic mechanism and chart to zero and start the machine. Strip the separating member from the specimen approximately at an angle of 1 80L and continue the separation for a sufficient distance to indicate the peel or stripping value. Peel at least one half of the bonded area, even though a peel or stripping value may be indicated before this point.
9. Calculation
9. 1 Determine the actual peel or stripping strength by drawing on the autograph ic chart the best average loud line that will accommodate the recorded curve. Report the load so indicated, corrected for any tare weight which may have been used with the specimen as described in 8.2 expressed in kilograms per millimetre (pounds per inch) of width for separation at 152.4 mm (6 in.)/min, as the peel or stripping strength for the particular specimen under test.
9.2 For each series of tests. calculate the arithmetic mean of all the values, obtained and report as the baverage value.”
10. Report
10. 1 Report the following:
10.1.1 Complete identilication of the adhesive and specimen tested, including types, source, manufacturer’s code numbers, form, etc.,
10.1.2 Method of preparing test specimens, including mixing and dispensing of adhesive,
10.1.3 Conditioning procedure used,
10.1.4 Testing room conditions,
10.1.5 Number of specimens tested,
10.1.6 Speed of testing,
10.1.7 Average value of peel or stripping strength.
10.1.8 Maximum and minimum strength values of the series,
10.1.9 individual test values, individual autographic charts, and other statistical data requested by the purchaser, and
10.1.10 Type of failure.
11. Precision and Bias
11 . I A precision and bias statement does not exist for this test method because resources necessary for round-robin testing have not been forthcoming.
