(Practice)Standard Practice for Cutting Film and Sheeting Test Specimens
Standard Practice for Cutting Film and Sheeting Test Specimens
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.
SCOPE
1.1 This practice covers equipment and techniques for cutting film and sheeting specimens for testing.2 The specimens are nick-free, non-stretched and can be rapidly prepared.
1.2 The values given in SI units are to be considered standard. The values given in parentheses are for information only.
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
Note 1: There is no known ISO equivalent to this standard.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

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.
