ASTM D6182-00(2015)

Standard Test Method for Flexibility and Adhesion of Finish on Leather

SIGNIFICANCE AND USE
5.1 This test method is intended for use on any type of finished leather.  
5.2 This test method will give an indication of the flexibility, adhesion, and strength of the finish on leather.
SCOPE
1.1 This test method is intended for use on finished leather to evaluate resistance to cracking, delamination, and discoloration of the finish when subjected to repeated flexing. This test method does not apply to wet blue.  
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

8. Sampling, Test Specimens, and Test Units
8.1 Sample leather according to Practice D2813.
8.2 Cut two test pieces 45 × 70 mm from each sample using a die. One piece cut parallel and the other perpendicular to the
backbone.
9. Conditioning
9.1 Dry Leather Test—Prepare the test pieces according to Practice D1610.
9.2 Wet Leather Test—Submerge the test pieces in distilled or deionized water for 20 6 1 min. Blot excess water off using
blotting paper or a paper towel.
9.3 Other Test—Conditioning, other than as prescribed, shall be documented in the results.
10. Procedure
10.1 Bring the upper clamp of the Bally Flexometer to its uppermost position.
10.2 Fold the test piece in half along its major axis with the finished side toward the middle.
10.3 Insert the folded test piece in the top clamp, and tighten the clamp.
10.4 Fold the test piece around the top clamp and down.
10.5 Lightly pinch the leather at the top clamp to remove slack and to position the downward fold vertically in the bottom
clamp. Tigh
