What is IEC 60335-2-36 ?

Title: A Comprehensive Guide to IEC 60335-2-56: Safety Requirements for Electrically Operated Hand Tools

The International Electrotechnical Commission (IEC) is a global organization that develops and publishes international standards for electrical products and systems. These standards are designed to ensure the safety, reliability, and performance of electrical equipment, systems, and components. One of the key standards that IEC publishes is IEC 60335-2-56, which specifically addresses the safety requirements for electrically operated hand tools.

In this article, we will provide a comprehensive guide to IEC 60335-2-56, exploring its scope, key requirements, and testing procedures. We will also compare the standard with other relevant safety standards, such as IEC 60572-1, to provide a more comprehensive understanding of the requirements for electrically operated hand tools.

Scope of IEC 60335-2-56:

IEC 60335-2-56 is an international standard that specifies the safety requirements for electrically operated hand tools. The standard is divided into four parts, each covering a different aspect of the hand tool's safety performance.

Part 1: General Principles and Requirements

This part of the standard provides general principles and requirements for the design, manufacture, and testing of electrically operated hand tools. It includes requirements for the materials used, the design of the hand tool, and the testing procedures used to evaluate its safety performance.

Part 2: Test Methods for Electrical Characteristics

This part of the standard provides detailed test methods for measuring the electrical characteristics of electrically operated hand tools, such as their resistance, voltage, and current.

Part 3: Test Methods for Fire Performance

This part of the standard includes test methods for evaluating the hand tool's ability to withstand a fire, including tests for the temperature and time required for the fire to spread.

Part 4: Test Requirements for Other Aspects

This part of the standard covers additional requirements for the hand tool, such as requirements for the user's physical capabilities, the environmental conditions in which the hand tool will be used, and the testing procedures used to evaluate the tool's performance in different environments.

Key Requirements of IEC 60335-2-56:

IEC 60335-2-56 is a comprehensive standard that provides a detailed set of requirements for the safety of electrically operated hand tools. The key requirements of the standard are as follows:

Electrical Safety: The hand tool must be designed and manufactured to minimize the risk of electrical shock or other electrical injuries. This is achieved by ensuring that the hand tool is made of non-conductive materials, has a securely grounded design, and is designed to operate within the limits of the equipment.

Fire Performance: The hand tool must be able to withstand a fire for the specified duration without suffering damage or failure. This is achieved by conducting a series of tests that verify the hand tool's ability to maintain its structural integrity and electrical performance in the presence of a fire.

Durability: The hand tool must be able to withstand the expected use and conditions without breaking or suffering damage. This is achieved by subjecting the hand tool to a series of tests that simulate the expected use and conditions.

User Comfort: The hand tool must be designed to provide a comfortable and safe grip for the user. This is achieved by ensuring that the hand tool is ergonomically designed, has an appropriate size and shape, and is made of materials that are resistant to the user's touch.

Environmental Considerations: The hand tool must be designed to operate in a wide range of environmental conditions, including high and low temperatures, humidity, and vibration. This is achieved by using materials that are resistant to these conditions and by ensuring that the hand tool is designed to maintain its performance in different environments.

Testing Procedures of IEC 60335-2-56:

IEC 60335-2-56 is a standard that is widely recognized in the field of electrical safety and hand tools. The standard specifies a series of testing procedures that must be followed to ensure that electrically operated hand tools are safe and reliable.

The testing procedures for IEC 60335-2-56 are as follows:
