1.1 本试验方法包括以下试验: 1.1.1 在餐具和中空器皿的中心以及中空器皿的边缘进行冲击试验，以及 1.1.2 餐具边缘的碎裂测试。试样可以上釉或不上釉。 注1: 试样中心的冲击试验用于确定:( 1. )产生初始断裂的冲击幅度，以及( 2. )产生完全故障所需的能量。在第一种情况下，初始断裂显示在与被敲击的工件相反的一侧，似乎是厚度平方和坯体或坯体釉料组合固有脆性的函数；它相对独立于试样的尺寸或设计。第二个因素更多地取决于设计，并且在给定的一组作品中往往会有很大的变化。 注2: 中空器皿边缘的冲击试验类似于碎裂试验，所获得的破坏类型有助于评估物体形状的影响。 注3: 除了车身的固有强度外，切削试验结果还受到轮辋轮廓的极大影响，在较小程度上受到轮辋厚度、叶片倾斜度和釉料配合的影响。 1.2 以英寸-磅单位表示的值应被视为标准值。括号中给出的值是对国际单位制的数学转换，仅供参考，不被视为标准值。 1.3 本标准并不旨在解决与其使用相关的所有安全问题（如果有的话）。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践，并确定监管限制的适用性。 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。 =====意义和用途====== 3.1 本试验方法的目的是预测产品在使用过程中对冲击断裂的抵抗力。

1.1 This test method covers the following tests: 1.1.1 Impact tests at the center of both flatware and hollow ware and at the rim of hollow ware, and 1.1.2 Chipping tests at the rim of flatware. Specimens may be either glazed or unglazed. Note 1: The impact test at the center of the specimen is used to determine: ( 1 ) the magnitude of a blow that will produce initial fracture, and ( 2 ) the amount of energy necessary to produce complete failure. In the first case, the initial fracture shows on the side of the piece opposite from that being struck and appears to be a function of the square of the thickness and of the inherent brittleness of the body or body-glaze combination; it is relatively independent of the size or design of the specimen. The second factor is more dependent upon design and often is subject to wide variation within a given group of pieces. Note 2: The impact test at the rim of hollow ware is similar to a chipping test, and the type of failure that is obtained is useful in evaluating the effect of the shape of the object. Note 3: In addition to the inherent strength of the body, chipping test results are greatly affected by contour of rim and to a lesser extent by thickness of rim, inclination of leaf, and fit of glaze. 1.2 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. 1.3 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. 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. ====== Significance And Use ====== 3.1 The purpose of this test method is to predict product resistance to impact breakage in service.
