1.1 本标准根据未装饰内部石膏板产品和纤维增强水泥板（耐滥用墙板）的耐磨性和抗冲击性能，建立了耐滥用性分类。 1.1.1 本标准是对石膏板产品性能进行分类的方法，并非旨在对耐滥用系统进行分类。 1.2 以英寸-磅和国际单位制（公制）表示的数值应单独视为标准。在正文中，国际单位制显示在括号中。每个系统中规定的值应独立于其他系统使用。两个系统的值不应合并。 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）。 本标准的使用者有责任在使用前制定适当的安全、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====== 4.1 耐虐待墙板的每种滥用/影响特性都分为三个分类级别。分类的三个级别是: 一级、二级和三级，其中一级代表任何给定房产的最低评级。规定的试验方法用于建立耐滥用墙板的耐滥用分类。每个分类级别都需要最低的总体指定性能。任何经过分类的耐滥用墙板都可以在低于最高合格等级的分类等级下使用。

1.1 This standard establishes classifications of abuse resistance based on the abrasion resistance and impact resistance performance of nondecorated interior gypsum panel products and fiber-reinforced cement panels (abuse resistant wall panels). 1.1.1 This standard is a method of classifying gypsum panel product performance and is not intended to classify systems for abuse resistance. 1.2 The values stated in inch-pound and SI (metric) units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system shall be used independent of the other. Values from the two systems shall not be combined. 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 ====== 4.1 Each abuse/impact property of abuse resistant wall panels is divided into three classification levels. The three levels of classification are: Level I, Level II, and Level III, with Level I representing the lowest rating for any given property. The test methods specified are utilized to establish the abuse-resistance classification of an abuse resistant wall panel. Each classification level requires a minimum overall specified performance. Any classified abuse resistant wall panel can be used at a classification level which is rated lower than the highest level qualified.
