1.1 本指南提供了无特定限制的信息，以帮助选择环境可接受的润滑剂（EAL）并在海洋应用中使用。 1.2 单位- 以国际单位制表示的数值应视为标准。本标准不包括其他计量单位。 1.3 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。 1.4 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====== 4.1 本指南旨在提供海洋应用中使用的环境可接受润滑剂（EAL）的信息。这些信息包括EAL类型、一般特性以及评估其技术性能的推荐方法。 此外，还总结了有关主要环境标准和其他组织以及定义、分类和规范EAL使用的许可证的一般信息。 4.2 本指南的另一个目标是提供简明表格，描述2013年EPA船舶通用许可证（VGP）中对定义为EAL的润滑剂的生物降解性、生态毒性和生物累积性要求。 4.3 本指南的范围是提供无特定限制的信息，以帮助选择EAL并在海洋应用中使用。 本指南的编制者旨在向船舶所有人和运营商、船舶维护工程师以及船舶原始设备制造商（OEM）润滑剂要求的编制者提供有关EAL及其在海洋应用中的使用的基本信息。

1.1 This guide provides information, without specific limits, to aid in the selection of environmentally acceptable lubricants (EALs) and use in marine applications. 1.2 Units— The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard. 1.3 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. 1.4 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 ====== 4.1 The purpose of this guide is to provide information on environmentally acceptable lubricants (EALs) used in marine applications. That information includes EAL types, general properties, and recommended means by which their technical performance can be evaluated. In addition, general information on the major environmental standards and other organizations and permits defining, classifying, and regulating the use of EALs are summarized. 4.2 Another goal of this guide is to provide concise tables that describe the biodegradability, ecotoxicity, and bioaccumulation requirements found in the 2013 EPA Vessel General Permit (VGP) for a lubricant to be defined as an EAL. 4.3 The scope of this guide is to provide information, without specific limits, to aid in the selection of EALs and use in marine applications. It is the intention of the preparers of the guide to provide a base knowledge of information on EALs and their use in marine applications to vessel owners and operators, vessel maintenance engineers, and preparers of marine original equipment manufacturer (OEM) lubricant requirements.
