1.1 本指南旨在帮助设计工程师、制造/工业工程师和生产经理选择最合适的清洁剂和工艺。本指南在选择过程中考虑了环境污染预防因素。 1.2 本指南不被视为可接受材料的数据库。它将指导工程师和经理完成清洁材料的选择过程，要求工程师根据手头清洁任务的清洁要求定制其选择。如果零件可以清洁并保持清洁，则可以通过几个具有清洁要求的工艺步骤进行循环。这消除了整个过程中额外的清洁过程步骤。 建议进行全寿命周期成本分析或性能/拥有成本研究，以比较可用的方法。 1.3 本指南适用于一般工业制造、设备维护和再制造操作，以及某种程度上机械零件和组件的精密清洁。它不适用于光学、医疗或电子应用，也不适用于干洗或超临界流体清洗。 1.4 以国际单位制或英寸-磅单位表示的数值应单独视为标准值。每个系统中规定的值不一定是精确的等价物；因此，为确保符合本标准，每个系统应独立使用，且两个系统的值不得组合。 1.5 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、健康和环境实践，并确定监管限制的适用性。 1.6 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 本指南适用于为制造、维护或大修规范制定清洁要求的任何人。 本指南旨在针对每个清洁任务的具体应用，并向设计工程师保证，工业或制造工程师选择的工艺将与零件材料和后续工艺兼容。本指南允许工业或制造工程师根据被清洁零件的材料定制清洁产品的选择；后续过程所需的清洁度；以及环境、成本、健康和安全问题。

1.1 This guide is intended to assist design engineers, manufacturing/industrial engineers, and production managers in selecting the best fit cleaning agent and process. This guide takes into account environmental pollution prevention factors in a selection process. 1.2 This guide is not to be considered as a database of acceptable materials. It will guide the engineers and managers through the cleaning material selection process, calling for engineers to customize their selection based on the cleaning requirements for the cleaning tasks at hand. If a part can be cleaned, and kept clean, it can be cycled through several process steps that have cleaning requirements. This eliminates extra cleaning process steps during the total process. A total life cycle cost analysis or performance/cost of ownership study is recommended to compare the methods available. 1.3 This guide is for general industry manufacturing, equipment maintenance and remanufacturing operations, and to some extent precision cleaning of mechanical parts and assemblies. It is not intended to be used for optical, medical, or electronics applications, nor is it intended for dry-cleaning or super-critical fluid cleaning. 1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other and values from the two systems shall not be combined. 1.5 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. 1.6 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 This guide is to be used by anyone developing cleaning requirements for specifications for manufacturing, maintenance, or overhaul. This guide has been designed to be application specific for each cleaning task and to assure the design engineer that the process selected by the industrial or manufacturing engineer will be compatible with both the part material and the subsequent process(es). This guide allows the industrial or manufacturing engineer to customize the selection of the cleaning product based on the materials of the part being cleaned; the cleanliness required for the subsequent process(es); and the environmental, cost, and health and safety concerns.
