1.1 本试验方法包括测定在相同抛光剂的干燥涂层上涂覆水乳液地板抛光剂的效果。该方法设计用于实验室台板测试。还提供了一种用于大面积测试的方法。提供了一个评级系统，以根据可重涂性能指示抛光剂的可接受性。 注1: 水乳液地板抛光剂的可重涂性是一种一般性能，其测定取决于在本试验方法中规定的特定条件下观察抛光剂的几种其他性能。 本可重涂性试验方法不用于评估其他性能，除非这些性能与在本试验条件下评估的特定抛光剂的可重涂性有关。 1.2 本文中观察到的光泽度仅扩展到在执行本试验方法时，在重新涂覆时不会出现明显的视觉光泽度损失，如果出现这种损失，则表明通过重新涂覆，光泽度特性发生了变形。 1.3 可重涂性故障的程度可以从调平故障的程度反映出来。只有当不合格是可重涂性观察的一部分时，才应观察不合格。 1.4 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。 1.5 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====== 5.1 作为保护和美化地板的可再生涂料，水乳液地板抛光剂的基本实际用途取决于良好的再涂性。该测试方法在产品开发和最终产品测试中都很有用，可以作为评估可重涂性的一种手段。

1.1 This test method covers the determination of the effects of the application of a water-emulsion floor polish over a dried coating of the same polish. The method is designed for laboratory bench panel testing. A method is also provided for large area testing. A rating system is provided to indicate the acceptability of the polish based on recoatability performance. Note 1: Recoatability of a water-emulsion floor polish is a general-performance property, and the determination of it is dependent upon the observation of several other properties of the polish under the specific conditions expressed in this test method. This test method for recoatability is not designed for the evaluation of other properties, except as these properties relate to the recoatability of the specific polish being evaluated under the conditions of this test. 1.2 Gloss as observed herein extends only to freedom from loss of apparent visual gloss upon recoating, in the execution of this test method, and should this loss occur, it indicates a distortion of the property of gloss, by recoating. 1.3 A degree of recoatability failure may be reflected from a degree of leveling failure. The failure to level should be observed only if it is to be a part of the observation of recoatability. 1.4 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. 1.5 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 ====== 5.1 The essential practical usage of water-emulsion floor polishes as renewable coatings to protect and beautify floors, depends upon satisfactory recoatability. This test method is useful both in product development and final product testing, as a means of evaluating recoatability.
