What is IEC 60335-3-20 ?

IEC 60335-3-20 and IEC 60335-250 are two important international standards published by the International Electrotechnical Commission (IEC) that are relevant to the subject of electrical and electronic safety.

IEC 60335-3-20 is a standard that defines the test method for vertical flame propagation for single or bundled electrical wires or cables. It is widely used to assess the fire behavior and resistance properties of cables in various industries. This standard provides a standard method for testing electrical cables to determine their ability to withstand fire and electrical hazards.

IEC 60335-250, on the other hand, is a standard that focuses on the safety requirements for household and similar electrical appliances. It sets out the maximum limits for electrical equipment, such as electrical fires, electrical shock, and electrical interference. This standard is important for protecting people from electrical hazards in the home.

Both IEC 60335-3-20 and IEC 60335-250 are important international standards that are widely recognized and followed by manufacturers and consumers to ensure the safety of electrical products. It is important to comply with the requirements of these standards when designing, manufacturing, and testing electrical products.
