警告——本文件中规定的产品搬运和使用可能存在危险 如果没有遵守适当的预防措施。本文件并非旨在解决所有问题 与使用相关的安全问题。这是本文件用户的责任 建立适当的安全和健康实践，并确定 使用前的监管限制。本文件规定了未使用的耐火和不易燃材料的最低要求 一般工业应用中用于静液压和流体动力系统的液压流体。事实并非如此 适用于不同要求的航空航天或发电应用。信息技术 为这些危险性较小的液体的供应商和最终用户以及制造商提供指导 指使用它们的液压设备。 ISO 6743-4对液压系统中使用的不同类型的流体进行了分类 在应用方面，本文件仅详细介绍以下内容:HFAE、HFAS、HFB、HFC、HFDR和HFDU。 HFAE、HFAS、HFB、HFC和HFDR是ISO 5598定义的“耐火”液体。大多数HFDU 与矿物油相比，液体的燃烧性能有所改善，但不在此限 定义和更合适地被视为“不易燃”液体。交叉引用:ISO 15029-1ISO 6296:2000ISO 3448ISO 20763ISO 760ISO 7120ISO 5598ISO 4263-2ISO 7745ISO 12185ISO 6619ISO 9120ISO 20843ISO 4404-2ISO 6618ISO 4259-2ISO 14935ISO 20764EN 14832ISO 20623ISO 20783-1ISO 20823EN 14833ISO 3170ISO 14635-1ISO 20844ISO 6743-4ISO 3675ISO 6072ISO 4404-1ISO 6247ISO 2160ISO 15029-2ISO 20783-2CEN/1445EN当前所有修订版均可在购买时间包含在购买本文件中。

WARNING — The handling and use of products as specified in this document can be hazardous if suitable precautions are not observed. This document does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this document to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use.This document specifies the minimum requirements of unused fire-resistant and less flammable hydraulic fluids for hydrostatic and hydrodynamic systems in general industrial applications. It is not intended for use in aerospace or power-generation applications, where different requirements apply. It provides guidance for suppliers and end users of these less hazardous fluids and to the manufacturers of hydraulic equipment in which they are used. Of the categories covered by ISO 6743-4, which classifies the different types of fluids used in hydraulic applications, only the following are detailed in this document: HFAE, HFAS, HFB, HFC, HFDR and HFDU. Types HFAE, HFAS, HFB, HFC and HFDR are "fire-resistant" fluids as defined by ISO 5598. Most HFDU fluids, while displaying an improvement in combustion behaviour over mineral oil, fall outside this definition and are more appropriately considered as "less flammable" fluids.Cross References:ISO 15029-1ISO 6296:2000ISO 3448ISO 20763ISO 760ISO 7120ISO 5598ISO 4263-2ISO 7745ISO 12185ISO 6619ISO 9120ISO 20843ISO 4404-2ISO 6618ISO 4259-2ISO 14935ISO 20764EN 14832ISO 20623ISO 20783-1ISO 20823EN 14833ISO 3170ISO 14635-1ISO 20844ISO 6743-4ISO 3675ISO 6072ISO 4404-1ISO 3104ISO 4263-3ISO 6247ISO 2160ISO 15029-2ISO 20783-2CEN/TR 14489:2005All current amendments available at time of purchase are included with the purchase of this document.
