1.1 本指南的目的是建立一个程序，为富氧系统选择清洁剂，包括溶剂和水基洗涤剂。这包括清洁效果、材料兼容性和氧气兼容性的实验室规模测试。 1.2 特定清洁剂的有效性取决于其使用方法、污染物的性质和类型以及被清洁物品的特性，例如尺寸、形状和材料。清洁剂的最终评估应包括实际产品和生产过程的测试。 1.3 不同的清洁活动可能需要不同的清洁剂，例如水超声清洁、喷雾清洁、手擦拭和现场应用中的氧气管线冲洗。 1.4 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。 1.5 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《国际标准、指南和建议制定原则决定》中确立的国际公认标准化原则制定的。 =====意义和用途====== 3.1 本指南旨在提供在选择和鉴定富氧系统的清洁剂时可考虑的信息。 3.2 清洁度不足会导致污染物或部件被各种机制点燃。因此，应确定富氧服务中每种使用条件的可接受污染水平。可接受的污染水平可能取决于各种因素，例如: 3.2.1 污染物的性质和类型， 3.2.2 污染的位置和程度， 3.2.3 基底材料的类型， 3. 2.4 待清洗设备或部件的配置和最终用途，以及 3.2.5 富氧系统的操作参数（压力、温度、相、浓度、流体速度等）。

1.1 The purpose of this guide is to establish a procedure to select cleaning agents, both solvents and water-based detergents, for oxygen-enriched systems. This includes laboratory-scale tests for cleaning effectiveness, materials compatibility, and oxygen compatibility. 1.2 The effectiveness of a particular cleaning agent depends upon the method by which it is used, the nature and type of the contaminants, and the characteristics of the article being cleaned, such as size, shape, and material. Final evaluation of the cleaning agent should include testing of actual products and production processes. 1.3 Different cleaning agents may be required for different cleaning activities, such as aqueous ultrasonic cleaning, spray cleaning, hand wiping, and flushing of oxygen lines in field applications. 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, health, and environmental 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 ====== 3.1 The purpose of this guide is to provide information that may be considered when selecting and qualifying a cleaning agent for oxygen-enriched systems. 3.2 Insufficient cleanliness can result in the ignition of contaminants or components by a variety of mechanisms. Therefore, an acceptable level of contamination for each condition of use in oxygen-enriched service should be defined. The acceptable level of contamination may depend on various factors, such as: 3.2.1 The nature and type of the contaminants, 3.2.2 The location and degree of contamination, 3.2.3 The type of substrate material, 3.2.4 The configuration and end use of the equipment or part to be cleaned, and 3.2.5 The operating parameters of the oxygen-enriched system (pressure, temperature, phase, concentration, fluid velocity, etc.).
