PAINT ADHESION TEST
Application
This method is used to measure the relative adhesion of paint to steel, aluminum, galvanized steel, plastic, or other substrates.
Apparatus Required
Knife
A pocket knife of good quality is required for Method "A" and "C" of this procedure as outlined for
scratch test. It must have a 65 - 75 mm long blade and be 10 mm wide.
Scriber
A carbide-tipped scriber must be used in Method "B" and "D" of this procedure for the scriber test.

Materials Required
Panels
See FLTM BI 103-02 for panel preparation.
Adhesion Tape
No. 898 (Minnesota, Mining and Manufacturing Co. - 3M) 25 mm wide. Use only No. 898 tape that is made in the North America. Other No. 898 tapes have different adhesion characteristics. Store in the original package in a dry, dark location.

Conditioning and Test Conditions
All test values indicated herein are based on material conditioned in a controlled atmosphere of 23 +/- 2 °C and 50 +/- 5 % relative humidity for not less than 24 h prior to testing and tested under the same conditions unless otherwise specified.
Procedure
1. When the paint adhesion test is required after another test procedure, the adhesion test must be
performed within 30 minutes of the previous test or as otherwise specified by the applicable Engineering Material Specification.
2. Measure and record film thickness, prior to adhesion test in accordance with FLTM BI 117-01.
3. Remove all loose debris (brush off) from the scribe line prior to tape test.
Method "A" - Scratch Test 1. On an unmarked section of the test panel, draw the knife blade across the panel for a distance of
50 mm with sufficient pressure to remove a narrow ribbon of paint down to the base metal. The flat part of the blade should be inclined away from the operator at an angle of approximately 30° to the panel and drawn towards him/her to remove the ribbon of paint.
2. Examine and report any flaking or chipping or paint away from the scratch marks.
Method "B" - Scribe Test 1. Scribe lines through the paint to the base material as shown:
The scribed lines shall be 3 mm apart, at right angles and diagonally in one direction. 测试方法Ｂ－百格测试
撕下胶带后，观察并记录涂层脱落或附着力差的涂层比例（分级系统，请参考图１、图２、图３）。

2. 3M No. 898 tape shall be applied by pressing firmly and removing within 90 +/- 30 s of application by pulling it off rapidly (not jerked) back upon itself at as close to an angle of 180° to the panel as possible.
3.
Observe and report occurrence of chipping, flaking or general poor adhesion as noted after removal of tape. (Refer to Figures 1, 2 and 3 for classification system).
Method "C" - Parallel Scratch Test 1. Draw the knife blade across the test panel at an angle of 90° to the specimen for a length of 50 mm
or as long as possible with sufficient pressure to cut through the paint down to the base material. The knife blade should be drawn towards the operator. Draw a second parallel line in the same way 2 mm apart from the first.
2. Apply tape over the drawn lines in a parallel direction using firm finger pressure to ensure contact
with the panel surface (i.e., drawn lines to be visible).
3. Remove the tape within 90 +/- 30 s of application by pulling back rapidly (not jerked) back upon
itself at as close to an angle of 180° to the panel as possible.
4. Report occurrence of chipping, flaking, or general poor adhesion as noted after removal of tape.
Plastic and glass-fiber substrates may also fracture. In the absence of loss of paint adhesion such chipping shall be ignored.
Method "D" - Scribe Test for Two-Component Urethane Coatings
Note: This method will prevent the bridging of the tape between the scribe lines that occur when
the small grid us used.
1. Scribe the paint film to be tested as illustrated below. The grid should be approximately 25 mm
wide.
2. Place the tape over the grid parallel with the long points of the diamonds as indicated by the arrow.
3. Conduct the test as in Steps 2 and 3 of Method B.
使用３Ｍ的８９８号胶带粘贴，以９０＋／－３０ｓ的速度，１８０度方向快速、无停顿地撕下。

4. If the test removes one diamond, that is a pass. Two or more removed is a failure. This indicates
a Grade 1 or better classification.
Chemicals, materials, parts, and equipment referenced in this document must be used and handled properly. Each party is responsible for determining proper use and handling in its facilities.
