Standard Practice for Quality Control Receipt Inspection Procedures for Protective Coatings (Paint), Used in Marine Construction and Shipbuilding 船舶建造和造船用防护涂层(涂料)的质量控制接收检验程序的标准实施规程
发布日期: 2019-12-01
1.1 本规程规定了为最终产品在船舶和其他海洋结构物上使用而采购的防护涂层(油漆)的质量控制验收程序。实践包括验证收到的涂层材料是否在最初规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。 1.3 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》中确立的国际公认标准化原则制定的。 ====意义和用途====== 5.1 本规程提供了一种方法,以确保在船舶建造和维护期间提供的产品与原始选择所依据的材料基本相同。船用涂料的选择通常涉及实验室和现场评估候选材料,作为规范过程的一部分。当选择油漆时,在整个交付期内,其成分和特性应与最初评估的材料相同。 5.1.1 当观察到成分或油漆特性发生重大变化时,有必要确定变化的原因(生产误差或配方变化)及其对涂层性能的影响。如果需要更改配方,应采取的措施如 6.5 . 5.2 本规程并不涵盖所有可能用于识别涂层的化学或物理测试。 可能需要额外的测试来满足特定的用户需求。 5.3 本规程不建议所示试验的具体公差限制。公差值需要由涂层供应商、造船厂和船东商定。 5.4 这种做法没有建立必须控制的关键属性。这些属性由造船厂和船主根据具体需要(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).
