Crimpers, Applicators, Presses: 90157-1 Application Field and Working Principle

Introduction

Crimpers, applicators and presses are widely used in industrial quality control and automation. They offer precise mechanisms for quickly and accurately cutting, forming, and pressing a wide variety of metals and non-metals. The International Electrotechnical Commission (IEC) standard 90157-1 is an international standard that defines the requirements and test methods for the safety and performance of these tools. This article will discuss the application fields and the working principle of 90157-1.

Application Fields

The application fields of 90157-1 are vast. It is suitable for most types of mechanical work that use crimpers, presses, and applicators. These include but are not limited to:

• Television industry (flat panel TVs, refrigerator seals, etc.)
• Automotive industry (including light and heavy vehicles)
• Appliance industry (washing machines, refrigerators, etc.)
• Electrical/electronic industry (connecting wires, panel assembly, etc.)
• Furniture industry (fabrication of furniture and other wood components)
• Plastics industry (injection molding, extrusion molding, etc.)
• Medical industry (drug packaging and device assembly)
• Packaging industry (labeling, sealing, etc.)

Working Principle

IEC 90157-1 requires the following performance and safety tests, depending on the type of tool being used:

• Durability: Durability tests help to evaluate mechanical stresses or environmental conditions that a tool might be exposed to. This includes the ability to withstand vibration and shock, impact tolerance, and corrosion resistance.
• Strength: Strength tests help to measure a tool\'s mechanical strength. This includes tensile strength, bend strength, and compression strength. It also tests a tool’s ability to hold a set load and resist overload.
• Electrical safety: The IEC 90157-1 standard tests a tool’s adherence to electrical safety standards by measuring its electrical leakage current, breakdown voltage, and dielectric strength.
• Functional safety: The standard also tests a tool’s adherence to functional safety standards by making sure that it can safely and properly complete its intended functions.

Conclusion

IEC 90157-1 is an international standard that defines the requirements and test methods for the safety and performance of crimpers, applicators, and presses. It is suitable for most mechanical work involving these tools, including those in the television, automotive, appliance, electrical/electronic, furniture, plastics, medical, and packaging industries. This standard evaluations a tool\'s durability, strength, electrical safety, and functional safety.
