1.1 本规程规定了金属去除液、添加剂和抗菌剂的选择和安全使用指南。这包括产品选择、储存、分配和维护。 1.2 与水混溶的金属去除流体通常以高稀释度使用，并且稀释率变化很大。此外，还可能接触到生产的未稀释的金属去除液，以及金属去除液添加剂和抗菌剂。 1.3 直馏油通常由经过严格溶剂精制或加氢处理的石油、合成油或其他动物或植物来源的油组成，包括针对性能特性进行改性的油（例如酯化菜籽油等）。 直馏油在使用前不得用水稀释。添加剂通常包含在直馏油配方中。 1.4 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。 1.5 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。 1.6 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====== 4.1 使用这种做法将改善金属去除液的管理和控制。正确的管理和使用将减少与这些液体相关的皮肤和其他职业危害。 4.1.1 指导 第2148页 介绍了如何使用与金属加工和金属去除液的健康和安全相关的文件的信息，包括本文件。指南中引用的文件 第2148页 分组为适用于生产者、用户或所有人。 4.1.2 实践 第2693页 和 第1889页 通过提供关于预防皮炎和减少接触不同类型的金属去除液相关气溶胶的方法的信息，增加本实践中提供的信息。

1.1 This practice sets forth guidelines for the selection and safe use of metal removal fluids, additives, and antimicrobials. This includes product selection, storage, dispensing, and maintenance. 1.2 Water-miscible metal removal fluids are typically used at high dilution, and dilution rates vary widely. Additionally, there is potential for exposure to undiluted metal removal fluid as manufactured, as well as metal removal fluid additives and antimicrobials. 1.3 Straight oils generally consist of a severely solvent-refined or hydro-treated petroleum oil, a synthetic oil, or other oils of animal or vegetable origin, including oils that are modified for performance characteristics (for example, esterified rapeseed oil, and so forth). Straight oils are not intended to be diluted with water prior to use. Additives are often included in straight oil formulations. 1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.5 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. 1.6 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 Use of this practice will improve management and control of metal removal fluids. The proper management and use will reduce dermal and other occupational hazards associated with these fluids. 4.1.1 Guide E2148 covers information on how to use documents related to health and safety of metalworking and metal removal fluids, including this document. Documents referenced in Guide E2148 are grouped as applicable to producers, to users, or to all. 4.1.2 Practices E2693 and E2889 augment the information provided in this practice by providing information on prevention of dermatitis and on approaches to reducing exposures to different types of metal removal fluid related aerosols.
