1.1 这些试验方法包括刨平、布线/成型、车削、榫眼、钻孔和砂光的程序，所有这些都是木制品制造中常用的木材加工操作。这些试验在不同程度上适用于两类材料: 1.1.1 木材形式的木材，以及 1.1.2 木基面板材料，如胶合板和木基纤维和颗粒板。 1.2 由于规划的重要性，为了确定最佳条件，对影响该操作结果的一些变量进行了探索。然而，在大多数其他测试中，有必要将工作限制在一组相当典型的商业条件下，在这些条件下，所有不同的木材都被同等对待。 1.3 在对给定木材或木质底板的加工性能进行全面评估时，有几个因素。建议将成品表面质量作为评估加工性能的基础。切削工具的消光率和切削过程中消耗的功率也是重要的考虑因素，但超出了这些试验方法的范围。 1.4 虽然所介绍的方法包括了加工性能评估的逐步发展结果，但预计将进一步改进。例如，通过目前的程序，通过目视检查评估成品表面的质量，但随着新的机械或物理技术的出现，将提高评估精度，应采用这些技术。 1.5 以英寸-磅单位表示的数值应视为标准值。括号中给出的值是国际单位制的数学转换，仅供参考，不被视为标准。 1.6 本标准并不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建立适当的安全和健康实践，并确定监管限制的适用性。 1.7 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ===意义和用途====== 4.1 进行机械加工试验，以确定不同种类木材和不同人造板材料在各种机械操作下的工作质量和特性，如商业制造实践中遇到的。这些试验为比较不同产品在木工机械操作方面的性能提供了系统基础，并为评估其在某些用途中的潜在适用性提供了系统依据，其中这些性能至关重要。

1.1 These test methods cover procedures for planing, routing/shaping, turning, mortising, boring, and sanding, all of which are common wood-working operations used in the manufacture of wood products. These tests apply, in different degrees, to two general classes of materials: 1.1.1 Wood in the form of lumber, and 1.1.2 Wood-base panel materials such as plywood and wood-base fiber and particle panels. 1.2 Because of the importance of planing, some of the variables that affect the results of this operation are explored with a view to determining optimum conditions. In most of the other tests, however, it is necessary to limit the work to one set of fairly typical commercial conditions in which all the different woods are treated alike. 1.3 Several factors enter into any complete appraisal of the machining properties of a given wood or wood-base panel. Quality of finished surface is recommended as the basis for evaluation of machining properties. Rate of dulling of cutting tools and power consumed in cutting are also important considerations but are beyond the scope of these test methods. 1.4 Although the methods presented include the results of progressive developments in the evaluation of machining properties, further improvements are anticipated. For example, by present procedures, quality of the finished surface is evaluated by visual inspection, but as new mechanical or physical techniques become available that will afford improved precision of evaluation, they should be employed. 1.5 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.6 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. 1.7 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. ====== Significance And Use ====== 4.1 Machining tests are made to determine the working qualities and characteristics of different species of wood and of different wood-based panel materials under a variety of machine operations such as are encountered in commercial manufacturing practice. The tests provide a systematic basis for comparing the behavior of different products with respect to woodworking machine operations and of evaluating their potential suitability for certain uses where these properties are of prime importance.
