1.1 本规程涵盖了金属铸造操作中使用的机械和设备的设计、施工和操作要求，包括砂制备、成型和制芯、熔化和浇注以及清洁和修整。本规程不适用于压铸操作。 1.2 目的- 本规程的要求，包括对主管和员工的培训，旨在最大限度地减少操作和维护人员在指定设备上或附近工作时受伤的可能性。遵守这一做法，结合OSHA法规，可以提供相对安全的环境，这是帮助预防职业伤害的基本必要条件。 1.3 应用程序: 1.3.1 新安装- 出版日期后，本规范范围内的所有新装置应符合其要求。任何移动到新工厂或同一工厂内其他位置的现有机器安装在新位置时，视为新安装。 然而，将现有安装的机器（以前的安装）移动一小段距离，例如，以提供额外的通道空间，则不视为新安装。 1.3.2 现有装置- 在本实施规程的批准日期之后，应根据需要对该日期当天或之前存在的装置进行修改，以符合本实施规程的所有要求。如果不可能按照本惯例修改现有设施，则应注意缺陷，并在任何未来设施或设备变更中包括合规计划。在本规程发布之日，已订购或正在施工的设施和设备应视为现有装置。如果现有设备缺乏必要的员工保护（个人防护设备或行政控制），则此做法适用于现有设备。 1.4 以英寸/磅为单位的数值应视为标准值。 括号中的值仅供参考。 1.5 本惯例的文本参考了提供解释材料的注释和脚注。这些注释和脚注（不包括表和图中的注释和脚注）不应视为本标准的要求。 1.6 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户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。 1.7 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）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》中确立的国际公认标准化原则制定的。

1.1 This practice covers the requirements of applying the design, construction, and operation of the machinery and equipment used in metal casting operations—sand preparation, molding and core making, melting and pouring, and cleaning and finishing. This practice does not apply to die casting operations. 1.2 Purpose— The requirements of this practice, including the training of supervisors and employees, are intended to minimize the possibility of injury to operating and maintenance personnel while working on, or in the vicinity of, the specified equipment. Compliance with this practice, in conjunction with OSHA regulations, provides a relatively safe environment, which is a fundamental requisite in helping to prevent occupational injuries. 1.3 Application: 1.3.1 New Installations— After the date of publication, all new installations within the scope of this specification shall be in conformance with its requirements. Any existing machine installation moved to a new plant or another location in the same plant is deemed a new installation when it is installed in the new location. However, an existing installed machine (former installation) that is moved for a short distance, for example, to provide additional aisle space, is not deemed to be a new installation. 1.3.2 Existing Installations— After the approval date of this practice, installations existing on, or before, this date shall be modified as necessary to be in conformance with all requirements of this practice. Where it is not practical to modify an existing facility in conformance with this practice, deficiencies shall be noted and plans for compliance shall be included in any future facility or equipment changes. Those facilities and equipment on order or in the process of construction on the date of publication of this practice shall be considered as an existing installation. This practice applies to existing equipment if it lacks the necessary employee protection (personal protective equipment or administrative controls). 1.4 The values stated in inch/pound units are to be regarded as the standard. The values in brackets are for information only. 1.5 The text of this practice references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard. 1.6 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. 1.7 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.
