1.1本试验方法包括在环境条件下测量切割尺寸的办公纸的卷曲度。测试方法通常用于评估规范D 3460中所述的纸张，或在复印机或打印设备中处理后使用。 1.2切割尺寸的办公纸通常被描述为尺寸为8½x 11英寸。，8½x 13英寸。，8½x 14英寸。，11乘17英寸。 1.3 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。 ====意义和用途====== 切纸卷曲度对纸张的预期用途起着重要作用。经常切割的纸张用于高速运行的复印机和复印机。固有卷曲，即进入过程前的卷曲和成像过程中形成的卷曲，可能会影响其性能，尤其是在双工（两个）时- 涉及侧面打印）或校对。常见问题包括干扰和错位。 开发测试方法的经验仅限于常用切割尺寸的无涂层书写纸。该技术是基本的，可用于涂布纸和纸板，以确定卷曲的类型和大小。 该测试方法确定了一组板材中卷曲的类型和程度，并且没有解决单个板材中可能固有的变化。如果在测试过程中观察到一个或多个薄板以与提升相反的方式反应，则应注意。单个板材的卷曲度不一定由该程序确定。

1.1 This test method covers the measurement of curl in cut-sized office papers at ambient conditions. The test method would typically be used in evaluating papers described in Specification D 3460 or after processing in a copier or printing device. 1.2 Cut-sized office papers are generally described as having dimensions of 8½ by 11 in., 8½ by 13 in., 8½ by 14 in., and 11 by 17 in. 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. ====== Significance And Use ====== Curl in cut sized paper plays an important part in how paper performs in its intended use. Frequently cut-sized papers are used in duplicators and copy machines operating at high speeds. Inherent curl, that is, curl in the ream before entering the process and curl developed during the imaging process, can affect its performance, especially if duplexing (two-side printing) or collating is involved. Common problems experienced include jamming and misregistration. The experience used in developing the test method was limited to uncoated writing papers in the commonly used cut sizes. The technique is basic and could be used with coated papers as well as paperboard to identify the type and magnitude of curl. The test method identifies the type and degree of curl in a pack of sheets and does not address variations that might be inherent in individual sheets. If during the testing process it is observed that one or more sheets reacts in a contrary manner to the lift, it should be noted. Curl of a single sheet may not necessarily be determined by this procedure.
