1.1 这种做法旨在协助制定污染控制的正式计划，特别是航空航天关键表面的污染控制计划。需求可以由客户或系统集成商在系统级别建立，也可以在子系统级别建立。子系统需求可能是由负责的子系统供应商强加的，也可能是系统组织提出的( 4.7 )。所需的细节程度和清洁度水平可能因所建造硬件的特定应用和类型而异，但污染控制的所有方面都必须包含在最终计划中。因此，污染控制计划（CCP）中必须考虑以下各要素: 1.1.1 清洁度要求 用于处理颗粒、分子或生物污染物或其组合的可交付硬件。 指定污染限制和任何预算分配。 1.1.2 实施计划 以达到、验证和保持规定的清洁度要求。规定材料和工艺控制、清洁技术、验证测试、保护和预防计划、运输控制以及差异纠正措施。 1.1.3 环境控制 包括要使用的清洁设施、设施维护和监测时间表。 1.1.4 人员和操作控制 包括操作程序、限制、培训、激励和组织责任，包括实施和验证CCP的组织或个人。 1.2 以国际单位制表示的数值应视为标准。本标准中不包括其他计量单位。 1.3 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。

1.1 This practice is intended to assist in the preparation of formal plans for contamination control, especially of aerospace critical surfaces. Requirements may be established at the systems level, either by the customer or the systems integrator, or at the subsystem level. Subsystem requirements may be imposed by the responsible subsystem supplier or they may be flowed down from the systems organization ( 4.7 ). The extent of detail and level of cleanliness required can vary with the particular application and type of hardware being built, but all aspects of contamination control must be included in a final plan. Therefore, each of the following elements must be considered for inclusion in a contamination control plan (CCP): 1.1.1 Cleanliness requirements for deliverable hardware addressing particulate, molecular, or biological contaminants or combination thereof. Specify contamination limits and any budget allocations. 1.1.2 Implementation plans to achieve, verify, and maintain the specified cleanliness requirements. Specify material and process controls, cleaning techniques, verification tests, protection and prevention plans, transportation controls, and corrective action for discrepancies. 1.1.3 Environmental controls including clean facilities to be used, facility maintenance, and monitoring schedule. 1.1.4 Personnel and operational controls including operating procedures, restrictions, training, motivation, and organizational responsibilities including the organization or individual for implementation and verification of the CCP. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3 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.
