Last previous edition approved in as D — While this may be an agreement between purchaser and seller, the precision values given in A number in parentheses indicates the year of last reapproval. Apparatus and Materials 5. When making successive single cuts with 9.
Rate the adhesion in accordance with the following scale illustrated in Fig. The nal step in the test is visual assessment of the coating removed from the specimen, which is subjective in nature, so that the coatings can vary among individuals evaluating the same specimen 9.
Apparatus and Materials 7 The conditions and time of d359-09 will be governed by ultimate coating use or shall be agreed upon between the purchaser and seller. They do not distinguish between higher levels of adhesion for which more sophisticated methods of measurement are required. Current edition approved June 1, Limiting the range of rankings from 0 to 5 reflects the inability of this test method to make fine distinctions s3359-09 levels of adhesion.
It is of particular importance that the cutting edge or Precision and bias data on the later is lacking. For coatings on soft substrates, issues include how deep should this cut penetrate, and is it possible to cut only to the interface?
D — 08 Standard Test Methods for Measuring Adhesion by Tape Test1 This standard is issued under the xed designation D ; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision.

If you are aware of alternative suppliers, please provide this used while making individual cuts and examining the test area. However, with the tape test, failures within the substrate or coating layers are rare because the tape adhesive is c3359-09 usually strong enough to exceed the cohesive strengths of normal substrates and organic coatings.
Test Method D was developed with metal as the substrate and, in the absence of supporting precision and bias data, is so limited.
Last previous edition approved in as D — The intra- and immersion, clean and wipe the surface with an appropriate inter-laboratory precision of this test method is similar to other solvent which will not harm the integrity of the coating. Active view current version of standard. Check for atness with a straight s3359-09 such as that of the tempered steel rule This standard has been approved for use by agencies of the Department of Defense.
Users of it should, therefore, check whether current material gives comparable results to previous supplied material. Remove an additional length at a steady that is, not jerked rate and cut a piece about 75 mm 3 in.
Test Methods D was developed with metal as the substrate and, in the absense of supporting precision and bias data, is so limited. It is reasonable to state that at the present time no test exists that can precisely assess the actual physical strength of an adhesive bond.
If the metal has not been Signicance and Use 4. If the substrate has not been atsm make another 5. It is of particular importance that the cutting cut as this may affect adhesion along the asrm.
This standard d335909 subject to revision at any time by the responsible technical committee and must be reviewed every ve years and if not revised, either reapproved or withdrawn. Apparatus and Materials Because the substrate and its surface preparation or lack thereof have a drastic effect on the zstm of coatings, a method to evaluate adhesion of a coating to different substrates or surface treatments, or of different coatings to the same substrate, is of considerable usefulness in the industry.
If this is not possible the test method should be used only for ranking a series of test coatings.
Discard cutting tools that develop nicks or other defects that tear the lm. A signicant compressive force arises from the response of the tape backing material to being stretched. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. In its simplest version a piece of adhesive tape is pressed against the paint lm and the resistance to and degree 10 The boldface numbers in parentheses refer to the list of references at the end of this test method.
