What is IEC 60335-2-18:2020?

IEC 60335-2-18:2020 is a technical safety standard that specifies the requirements for electrically-operated heating pads, blankets, and similar flexible electrical appliances. This standard ensures the safety of these products by outlining various tests and criteria that they must meet.

The Scope of IEC 60335-2-18

The scope of IEC 60335-2-18 covers electrically-operated flexible heating appliances intended for household and similar use. It applies to appliances such as electric blankets, heating pads, and foot warmers. The standard addresses potential hazards related to both normal operation and abnormal situations, such as misuse or failure.

The standard covers various aspects of the appliance, including electrical safety, protection against overheating, mechanical strength, and resistance to environmental factors. It sets requirements for construction, performance, and markings on the product to ensure its safe use.

Testing Requirements According to IEC 60335-2-18

The standard presents a series of tests that the appliances need to pass in order to comply with the safety requirements. These tests include:

Ingress Protection (IP) Testing: This test verifies the degree of protection provided by the enclosure of the appliance against the entry of solids and liquids under various conditions.

Resistance to Heat: Appliances are tested to ensure that they can withstand exposure to high temperatures without posing a risk to users.

Leakage Current and Grounding: Tests are conducted to measure the leakage current of the appliance and ensure proper grounding to prevent electrical shock.

Mechanical Strength: This test evaluates the mechanical integrity of the product, including its resistance to forces that may occur during use or abuse.

Protection Against Overheating: The appliance's temperature control systems and thermal cut-off devices are tested to ensure they protect against excessive heating.

The Importance of Compliance with IEC 60335-2-18

Complying with IEC 60335-2-18 is crucial for manufacturers of electric heating appliances as it ensures the safety of their products. Meeting the requirements of this standard not only protects consumers from potential hazards but also demonstrates a commitment to quality and responsible manufacturing practices.

Consumers can look for the compliance marking indicating the product meets the safety requirements outlined by IEC 60335-2-18 when purchasing electric heating appliances. By choosing compliant products, users can have confidence in the safety and reliability of the appliances they use at home.
