"These test methods are under the jurisdiction of ASTM Committee D on. Packaging published as D – 76 Last previous cdition D/DM – ASTM D (Standard Test Method for Peel Adhesion of Pressure - Download as PDF File .pdf), Text File .txt) or read online. norma ASTM. ASTM D/DM() - Standard Test Method for Peel Adhesion of Pressure-Sensitive Tape includes different testing procedures.
Click here for more information on test Method A, which covers the location of the sample and the peel test procedure method which is common all of the degree methods once the specimen preparation is complete. The force required to effect the peel is measured and the average value calculated over the valid peel distance, which is used to calculate a peel adhesion value.
As for Method A plus thin polyester film, which is required to create an adherend which can be physically gripped. For each method, the sample preparation is very similar to that of D Method A , with additional steps to facilitate obtaining the appropriate adherends and hence adhesive [layer] to peel test. The test method, in terms of applying the grips and running the adhesion tester and performing the calculations are identical to that of Method A. This overview is intended to provide a basic understanding of the test procedure and suitable equipment to meet the standard.

Adherend 1. Adherend 2 Peeled.
Single -coated. Face side. Backing to panel. The carbon rubs specimen is of a different width, refer to Note 4.
A tolerance off onto the thin paper wrapper to reveal high spots or hollows on the of6 0. The length shall be rubber surface. It is proposed to use an electronic of tape from the sample roll before taking the specimens for machine taking at least one reading per mm [0. The tester shall have two clamps with centers in the 9. Where width or specimen wholly in the same plane; a means of moving the other factors causing a high adherence to backing makes it stressing clamp at a uniform rate of 5.
Conditioning 7. Reagents and Materials Other grades may be used, provided it is first period of not less than 24 h. Test at these conditions. Therefore, 7. Repeat for a total of three washes with this solvent.
If cleaned panel is not used within 10 h, it should 7. MEK or acetone. NOTE 3Discard panels showing stains, discoloration, or many 7.
Avoid contacting panel surface with fingers. During storage, test panels, be sure to read and follow all precautions on the panels should be protected from damage or contamination. Fold 12 mm [0.
ASTM D 3330 (Standard Test Method for Peel Adhesion of Pressure
Touch other end of the Apply mm [5 specimen to an end of the test panel. Hold the other end of the in.
Make four passes with the roller, twice positioned loosely above it. Roll mechanically or by hand in each direction at a rate of 10 6 0. This prevents entrapment of air between free tape. Do not disturb the line adhered to the tape on the the adhesive and the panel.
Should this occur, discard the panel. Double back the liner and proceed in accordance with specimen.
NOTE 4Where the width of the specimen is less than 24 mm [1 in. Apply a strip of prior to applying test specimen, apply a strip or strips of the tape, to give double-coated tape as wide as the specimen, the full length of an equivalent width of 24 mm [1 in. Remove the liner from the single-coated tape.
Make four passes with the roller, twice in each direction min. Separate the liner from the tape at the free end and cut away the free tape. NOTE 5Longer dwell time will give different results. Peel adhesion Do not disturb the liner adhered to the tape on the panel.
A longer Double back the liner and proceed in accordance with Clamp Test Method EAdhesion of Adhesive Transfer that end of the panel into the movable jaw of the adhesion Tapes testing machine and the free end of the tape into the other jaw.
Apply this film in mechanically peeled. Use the average force obtained during the manner of applying described in Proceed as described in Make two passes of the roller using a hand roller of the such as the standard stainless steel panel. Roll firmly. Apply a same size. Remove the liner from the tape and apply to a standard panel as described in Proceed as described second specimen with those of the strip in the test panel.
Complete testing as described in NOTE 7In spite of its apparent simplicity, the use of this test method is rather delicate and involves the use of great care in following the Test Method CAdhesion of Double-Coated Tape procedure as written to give coherent and identical results between one laboratory and another, as well as between one operator and another.
Apply this film in Place the so that the roller makes the actual application of the film to the panel into a fixture clamped to the moving jaw of the adhesion double-coated tape. Operate the moving jaw at 5. Continue in accordance with Calculation application of the tape to the film. Trim the film to be as wide Remove the liner. Continue Newtons N , convert to N per 10 mm by converting the pull in accordance with Use actual specimen Specimens of Different Material: width in calculations, 1 Before a meaningful statement can be made about two specific laboratories, the amount of statistical bias observations in 95 out of cases when both observations are between them, if any, must be established with each comparison being taken by the same well-trained operator using the same piece of based on recent data obtained on specimens randomly drawn from one test equipment and the specimens randomly drawn from the sample of the material to be evaluated.
Larger differences may occur under The true value of peel adhesion at ported in See Note 9 and Table 2.
It is believed that the precision for the other test methods would be similar. It would probably not apply to Adhesive to panel. Sampling 6. Request RR: average of the specific set of data which is of interest by the confidence limits D Africa Centre for Open Governance.

The adhesion line should be just below, but not touching, the lower part of the upper front jaw. Juber Shaikh.
