58274-2 is an international standard defining connectors and accessories used in crimping, applying, and pressing tools. It was issued by the International Electrotechnical Commission in 2017 and intended to provide a unified approach to the design, construction, purchasing, installation, and maintenance of press-hending systems for use in electrical and electronic systems. This article will discuss the application fields of 58274-2 and its working principle.

The application fields of 58274-2 include crimping, applying, and pressing tools for a variety of purposes including the assembly and maintenance of electronic systems, electrical connectors, and other components. It covers devices for both out-of-assembly and in-assembly operations and includes tools that can be used manually or with automated equipment. This standard is applicable to press-hending systems for entire strands, bundles of strands, and other conductors as well as for single cables, single conductors, and other components.

The working principle of 58274-2 primarily involves the use of force to effect a connection between two components. This force is generated either by manual hand tools or automated systems, depending on the size and complexity of the connection. In the case of manual tools, an operator compresses the tool with appropriate force until the two components are securely connected. Automated systems use a variety of methods such as hydraulic or pneumatic presses to apply the necessary force. Regardless of the method used, the tool must be able to withstand the applied force without damage to the components or tool itself.

58274-2 also specifies safety and performance requirements for press-handling systems. This includes requirements for press tools designed and manufactured according to the standard, as well as requirements for the tools in use. It states that press tools must be able to withstand the applied force without damage, which may include mechanical, electrical, and environmental stress, depending on the type of application. In addition, press tools must be inspected prior to use and be able to demonstrate adequate performance.

Finally, 58274-2 also provides guidance on installation and maintenance of press tools. It states that press tools must be securely fastened to their base, be properly lubricated, and inspected regularly for wear and tear. It also covers the testing of press tools prior to use and after use, as well as the maintenance and testing of press tools during use.

Overall, 58274-2 is an important standard for the use of press-hending systems for any kind of application. It provides a unified approach for the design, construction, purchasing, installation, and maintenance of press tools, and specifies safety and performance requirements for the tools. It also covers installation and maintenance of the tools, and provides guidance on testing and inspection. This ensures that press tools are able to withstand the applied force without damage and perform adequately when in use.
