Doplňující informace
| Significance and Use | ||||||
|
3.1 Many test methods including Test Methods D882, D2838, F88, F1921/F1921M, and F2029 require the use of narrow strips of varying length. The quality of the sample preparation directly affects test results. This practice describes three techniques for preparing samples with straight, clean, parallel edges with no visible imperfections. Note 2: After cutting, each specimen should be examined
visually to insure the edges are undamaged (free of nicks). On a
periodic basis specimen edge quality should be evaluated by
microscopic examination. To determine when cutting blades need to
be replaced or sharpened, a control chart of tensile strength and
percent elongation at break (see Test Method D882) of a uniform material may be
maintained. Tensile strength and percent elongation at break will
decrease as the quality of specimen cutting decreases.
