1.1 本规范规定了为船舶和其他海洋结构物最终产品使用而采购的防护涂料（油漆）的质量控制收据检验程序。该实践包括验证收到的涂层材料是否在最初指定和测试的物理和化学特性范围内的方法和程序。 1.2 本标准并不旨在解决与其使用相关的所有安全性问题（如果有）。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法规限制的适用性。 1.3 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》中确立的国际公认的标准化原则制定的。======意义和用途====== 5.1 这种做法提供了一种确保船舶建造和维护期间提供的产品与最初选择所依据的材料基本相同的方法。船上使用油漆的选择通常涉及对候选材料的实验室和现场评估，作为规范流程的一部分。当选择油漆时，其在整个交付期间应具有与最初评估的材料相同的成分和特性。 5.1.1 当观察到成分或涂料特性发生显著变化时，需要确定变化的原因（生产误差或配方变化）及其对涂料性能的影响。如果需要制剂变更，应采取的措施见 6.5 . 5.2 本实践并不意味着涵盖可用于识别涂层的所有可能的化学或物理测试。可能需要额外的测试来满足特定的用户需求。 5.3 本规范不推荐所示试验的特定公差限值。公差值需要由涂料供应商、造船商和船东商定。 5.4 这种做法没有建立必须控制的关键属性。这些属性由造船商和船东根据特定需求（例如颜色）选择。

1.1 This practice provides the quality control receipt inspection procedures for protective coatings (paints) procured for end item use on ships and other marine structures. The practice includes methods and procedures for verifying that coating materials received are within the range of physical and chemical characteristics as those originally specified and tested. 1.2 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. 1.3 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. ====== Significance And Use ====== 5.1 This practice provides a means of assuring that products supplied during ship construction and maintenance are substantially the same as the materials on which the original selection was based. The selection of a paint for shipboard use frequently involves laboratory and field evaluations of candidate materials as part of the specification process. When a paint is selected, it shall have the same composition and characteristics throughout the delivery period as the materials originally evaluated. 5.1.1 When significant changes in composition or paint characteristics are observed, it is necessary to determine the cause of the change (production error or formulation change) and its impact on coating performance. Actions to take if a formulation change is required are specified in 6.5 . 5.2 This practice is not meant to cover all possible chemical or physical tests that may be used to identify a coating. Additional tests may be needed to meet specific user needs. 5.3 This practice does not recommend specific tolerance limits for the tests indicated. Tolerance values need to be agreed upon by the coating supplier, the shipbuilder, and the ship’s owner. 5.4 This practice does not establish critical attributes that must be controlled. These attributes are selected by the shipbuilder and the ship’s owner based on specific needs (for example, colors).
