1.1 该指南提供了信息和明确性，以支持海上船舶和平台上的海洋卫生设备（MSD）的健康和维护，从而促进整个生命周期的有效操作和性能。这包括识别可能对MSD正确操作有害的化学品及其衍生物。本指南将有助于更好地了解某些化学品对默沙东系统健康和运行的影响，并提供指导，告知运营商有效运行和维护的最佳实践和程序。 本指南旨在帮助运营商和默沙东原始设备制造商（OEM）共同努力，确保有效的运营和维护，并减少因引入有害化学品而导致的性能退化。本指南主要适用于II型MSD（如第节所述 4. )安装在大型船舶上，并采用污水和灰水的生物处理。 注1: 本指南不构成法规或船舶船级社规则，如适用，应查阅这些法规或规则。 1.2 制定新产品规范或修订现有产品规范的制造商应遵循本文概述的实践和程序，并以涵盖类似商品的最新规范为指导。同样，船舶所有人/操作员应查阅本指南中关于在役操作和维护的内容。 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）。本标准的使用者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 The guide provides information and clarity to support the health and maintenance of Marine Sanitation Devices (MSDs) on maritime vessels and platforms to promote effective operations and performance throughout the lifecycle. This includes identification of chemicals and their derivatives that can be detrimental to proper MSD operations. This guide will promote better understanding of the impacts of certain chemicals on the health and operations of MSD systems, plus provide guidance to inform operators of best practices and procedures for effective operations and maintenance. This guide is designed to assist both operators and MSD Original Equipment Manufacturers (OEMs) in collaboratively working to ensure effective operations and maintenance, and to reduce performance degradations that result from the introduction of harmful chemicals. The primary application of this guide is to Type II MSDs (described in Section 4 ), installed on larger ships and employing biological treatment of sewage and gray water. Note 1: This guide does not constitute regulations or ship classification society rules, which should be consulted where applicable. 1.2 Manufacturers preparing new product specifications or revising existing ones should follow the practices and procedures outlined herein, and be guided by the latest specifications covering similar commodities. Similarly, vessel owner/operators should consult this guide regarding in-service operations and maintenance. 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.
