个体防跌落系统 第2部分:缓冲器

[中文适用范围]： ISO 10333 的这一部分规定了挂绳和能量吸收器的要求、测试方法、使用和维护说明、标记、标签和包装（视情况而定）。 系索和能量吸收器一起用作个人防坠落系统 (PFAS) 中的连接子系统，该系统将在未来的国际标准中指定（请参阅参考文献中的 ISO 10333-6）。 出于 ISO 10333 本部分的目的，指定了两类能量吸收器： a) 类型 1：用于 PFAS，由于安装原因，潜在自由落体距离可限制为最大 1.8 m，并且，如果发生坠落，制动力最大限制为 4.0 kN； b) 类型 2：用于 PFAS，由于安装原因，潜在自由落体距离可限制为最大 4.0 m，并且如果发生坠落，制动力限制为最大 6， 0 kN。 ISO 10333的本部分仅适用于仅限单人使用且总质量不超过100 kg的系索和能量吸收器。 注： 建议总质量（包括工具和设备）超过 100 kg 的防坠落设备的用户向设备制造商寻求有关该设备适用性的建议，这可能需要额外的测试。 就 ISO 10333 本部分而言，能量吸收器可以与挂绳、全身安全带 (FBH) 集成在一起提供，也可以单独提供。 ISO 10333 本部分的范围不延伸至： a) 包含不带能量吸收器或不带能量耗散装置的系索的 PFAS； b) 与 ISO 10333-4 中规定的 PFAS 组件一体的特殊系索和能量吸收器（即只能通过破坏或特殊工具分离）。 ISO 10333 的这一部分没有规定当系索和能量吸收器处于特殊使用条件下时适用的附加要求（例如，在进入工作场所和/或特定环境因素方面存在异常限制） 。 因此，ISO 10333 的本部分没有规定确保结构材料耐用性的处理（例如热处理、防腐处理、物理和化学危害防护），但应符合相应的国际标准，否则应符合相应的国际标准。 ，符合涉及相关物理特性和/或用户安全的国家标准和其他规范。 特别是当认为有必要测试设备金属部件的耐腐蚀性时，应参考ISO 9227。 [外文原描述]： This part of ISO 10333 specifies requirements, test methods, instructions for use and maintenance, marking, labelling and packaging, as appropriate, for lanyards and energy absorbers. Lanyards and energy absorbers are used together as a connecting subsystem in personal fall-arrest systems (PFAS) which will be specified in a future International Standard (see ISO 10333-6 in the Bibliography). Two classes of energy absorbers are specified for the purposes of this part of ISO 10333: a) Type 1: used in PFAS where, due to installation, the potential free-fall distance can be limited to a maximum of 1,8 m and, if a fall takes place, the arresting force is limited to a maximum of 4,0 kN; b) Type 2: used in PFAS where, due to installation, the potential free-fall distance can be limited to a maximum of 4,0 m and, if a fall takes place, the arresting force is limited to a maximum of 6,0 kN. This part of ISO 10333 is applicable only to lanyards and energy absorbers limited to single-person use of a total mass not exceeding 100 kg. NOTE Users of fall-protection equipment whose total mass (including tools and equipment) exceeds 100 kg are advised to seek advice from the equipment manufacturer regarding the suitability of this equipment, which may need additional testing. For the purposes of this part of ISO 10333, energy absorbers may be supplied integral to a lanyard, integral to a full body harness (FBH), or may be supplied separately. The scope of this part of ISO 10333 does not extend to: a) PFAS that incorporate lanyards without energy absorbers or without a means of energy dissipation; b) special lanyards and energy absorbers which are integral (i.e. can only be separated by mutilation or by special tool) to the PFAS components as specified in ISO 10333-4. This part of ISO 10333 does not specify those additional requirements that would apply when lanyards and energy absorbers are subjected to special conditions of use (where, for example, there exist unusual limitations concerning access to the place of work and/or particular environmental factors). Thus treatments to ensure the durability of the materials of construction (such as heat treatment, anti-corrosion treatment, protection against physical and chemical hazards) are not specified in this part of ISO 10333, but should comply with appropriate International Standards or, failing that, with national standards and other specifications dealing with relevant physical characteristics and/or the safety of users. In particular, when it is considered necessary to test the corrosion resistance of metallic parts of the equipment, reference should be made to ISO 9227.
