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粘合剂/密封剂或粘合/密封工艺。该指南在选择过程中考虑了环境污染预防和职业健康安全因素。 1.2 本指南不应被视为可接受材料的数据库。它将指导工程师和管理人员完成粘合剂/密封剂材料的选择过程，要求工程师根据指定应用的粘合或密封性能要求定制他们的选择。全面的选择过程将有助于建立更高效的生产流程，并可能消除不必要的工艺步骤。建议进行全生命周期成本分析或实施性能/成本研究，以比较可用的替代方案。 1.3 本指南适用于航空航天和通用操作。 它不适用于汽车、地毯、建筑、电子、医疗/牙科、光学或结构和非结构木材应用。请注意，本指南并非专门针对这些应用程序，但在这些应用程序的选择过程中可能会使用一般方法。 1.4 本标准并不旨在解决与其使用相关的所有安全问题（如果有的话）。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====== 5.1 本指南供任何制定制造、维护或检修规范的粘合或密封要求的人使用。本指南专为每种粘合或密封应用而设计，使设计工程师可以放心，工业或制造工程师选择的产品或工艺将与零件材料和后续工艺兼容，如被粘物/基材的清洁和制备。它允许工业或制造工程师根据粘合或密封部件的材料、后续工艺所需的条件、环境、成本以及健康和安全问题来定制粘合剂或密封剂产品的选择。

1.1 This guide is intended to assist design engineers, manufacturing/industrial engineers, and production managers in selecting the best-fit adhesive/sealant or bonding/sealing process. The guide takes into account environmental pollution prevention and occupational health and safety 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 adhesive/sealant material selection process, calling for engineers to customize their selection based on the bonding or sealing performance requirements for the specified application. A comprehensive selection process will allow for the establishment of a more efficient production process, and may eliminate unnecessary process steps. A total life cycle cost analysis or performance/cost of implementation study is recommended to compare the available alternatives. 1.3 This guide is for aerospace and general purpose operations. It is not intended to be used for automotive, carpet, construction, electronics, medical/dental, optical, or structural and nonstructural wood applications. Note that this guide is not specifically for these applications, but the general methodology may be used in the selection process for these 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 ====== 5.1 The guide is to be used by anyone developing bonding or sealing requirements for specifications for manufacturing, maintenance or overhaul. This guide has been designed to be application specific for each bonding or sealing application, and allows the design engineer to rest assured that the product(s) or process(es) selected by the industrial or manufacturing engineer will be compatible with both the part material and the subsequent processes, such as adherend/substrate cleaning and preparation. It allows the industrial or manufacturing engineer to customize the selection of the adhesive or sealant product based on the materials of the parts being bonded or sealed, the conditions required for the subsequent process(es), environmental, cost, and health and safety concerns.
