本欧洲标准适用于自动回切机，并规定了屠宰场所用机器的安全和健康要求，以便沿着背骨轴线全面自动分割肉类动物（牛肉和猪肉），将屠体分成两部分（见图1 ）。 本文档涉及与自动回切机相关的所有重大危险，危险情况和事件，按照预期使用和在制造商可合理预见的误用条件下使用（见第4章）。 本文件涉及EN ISO 12100-1，第5.3条定义的运输，组装和安装，调试和使用过程中的重大危险，危险情况和事件。 本文档不适用于自动回切机，该机器在其出版日期之前制造为EN。 本标准涉及的机器是用于屠宰场的机器。它们配有切割装置，并由电动，液压和/或气动能量驱动。 使用的切割工具有: - 圆锯， - 拆分工具 考虑三种类型的机器（见图1至5）: - 用于猪肉屠体的分离机，A型（分离器）， - B型猪圈屠宰机

This European standard applies to automatic back splitting machines and specifies safety and health requirements for machines used in slaughterhouses in order to fully automatically split meat animal (beef and pork) along the back-bone axis, splitting the carcass into two parts (see Figure 1). This document deals with all significant hazards, hazardous situations and events relevant to automatic back splitting machines, when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4). This document deals with the significant hazards, hazardous situations and events during transport, assembly and installation, commissioning and use as defined in EN ISO 12100-1, Clause 5.3. This document is not applicable to automatic back splitting machines, which are manufactured before the date of its publication as EN. The machines concerned by this standard are those used in slaughterhouses. They are fitted with a cutting device and are driven by electric, hydraulic and/or pneumatic energy. The utilized cutting tools are: - circular saws, - splitting tools. Three types of machines are considered (see Figures 1 to 5): - Splitting machines for pork carcasses, type A (splitter), - Splitting machines for pork carcasses, type B (circular saw), - Splitting machines for beef carcasses, type C (circular saw). There are two different operation cycles: - carcasses can be splitted when they are at standstill.(In general they are hanging on a sequence conveyed transport system.); - carcasses can also be splitted during their continuous movement by conveyor. In this case the movement of the tool is synchronized with that of the carcass. When the split is finished, the cutting tool returns automatically to its initial position. The machines run automatically. Under normal operating conditions there is no manual intervention.
