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.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.

5.1 This test method measures the quantity of sulfur available to react with metallic surfaces to form solid lubricating aids at the temperature of the test. Rates of reaction are metal type, temperature, and time dependent.1.1 This test method covers the determination of active sulfur in cutting oils. This test method applies to sulfur reactive with copper powder at a temperature of 150 °C (302 °F) in cutting fluids containing both natural and added sulfur.NOTE 1: It has not been established by ASTM Subcommittee D02.L0 as to how the active sulfur content thus determined may relate to field performance of the cutting fluid.1.2 The values stated in SI units are to be regarded as the 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.

This practice provides a common format that allows a computer design system to generate data that an output device can accurately reproduce independent of the hardware manufacturer.1.1 This practice specifies a data format for numerically-controlled cutting machines for fabric.1.2 This standard uses a subset of the defined instruction set defined in ANSI/EIA-274-D in addition to the codes defined by this practice.1.3 This practice does not support curve interpolation or definitions. All curves are represented by discrete vectors (stroked) and are dependent on the resolution of the CAD software.1.4 This practice requires that all coordinates are absolute, not relative.1.5 This practice only supports positive coordinates that are measured from a single X-Y origin point with coordinates (0,0). The origin point is specified as the lower left corner of the cut file.1.6 This practice intends to transfer a static image with no provision for editing.1.7 This practice imposes no limits on the width or length of the cut data. Physical limitations imposed by the hardware and their effects on the output are the responsibility of the hardware manufacturer.1.8 This practice does not support bite commands or any methods that insert multiple origin points or floating coordinate systems.1.9 This practice does not support notch tools.1.10 This practice does not support pattern matching.1.11 This practice limits the cut file to contain a single block of data demarked by a compatible header and terminator. Multiple blocks of data in a single file are not allowed.1.12 Any commands found in the cut file that are not defined by this standard shall be ignored.1.13 The intended application of this practice is limited to the class of output devices found in the sewn product industries that produce apparel, textiles, upholstery, and others that use soft or semi-rigid materials.1.14 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.
