What is UL 1283 2007 ?

Title: A Comprehensive Guide to UL 1283-2007 and UL 2556-2007

Power strips are an essential component in many electrical systems, providing power to various devices. However, power strips can pose a hazard if not designed and installed properly. To address this, the Underwriters Laboratories (UL) has established two standards that are crucial in ensuring the safety and reliability of power strips. In this article, we will provide a comprehensive understanding of both UL 1283-2007 and UL 2556-2007.

UL 1283-2007: Safety Requirements for Power Strips

UL 1283-2007 is a standard that specifies the safety requirements for power strips, also known as surge protectors. The purpose of this standard is to establish minimum safety requirements for power strips to prevent hazards such as electrocution, fires, and internal component failures. The standard covers aspects such as construction, performance, markings, and testing methods.

Construction Requirements

Power strips are made up of various components, including the casing, contacts, and internal components. The casing of the power strip must be made of non-corrosive materials that are resistant to extreme temperatures, such as heat and moisture. The contacts, which are responsible for delivering and releasing power, must be made of materials that are resistant to high temperatures, such as molten metal.

Performance Requirements

The performance requirements for power strips are essential in ensuring that they are able to withstand various conditions, including high temperatures, surges of power, and short circuits. The standard specifies various performance tests, such as voltage drop, current draw, and short circuit, that manufacturers must conduct to verify that their products meet the required standards.

Marking Requirements

The marking requirements for power strips are essential in ensuring that consumers are able to identify and use the products correctly. The standard specifies the marking requirements, including the use of symbols, letters, and numbers to indicate the various components of the power strip.

Testing Requirements

The testing requirements for power strips are essential in ensuring that the products are safe and reliable. The standard specifies various testing methods, including electrical continuity testing, voltage drop testing, and overload testing, that manufacturers must conduct to verify that their products meet the required standards.

UL 2556-2007: Technical Standard for Cable Flame Testing

UL 2556-2007 is a technical standard that specifies the requirements for wire and cable flame testing. The purpose of this standard is to ensure the safety and reliability of different types of wires and cables, including power strips. The standard covers various aspects, including the testing procedure, performance criteria, and symbols.

Testing Procedure

The testing procedure for UL 2556-2007 is essential in ensuring that manufacturers' products meet the required safety standards. The standard specifies the testing procedure, which includes the use of various types of tests, such as electrical continuity testing, insulation resistance testing, and fire resistance testing.

Conclusion

UL 1283-2007 and UL 2556-2007 are two essential standards that are crucial in ensuring the safety and reliability of power strips. By complying with these standards, manufacturers can ensure that their products meet the required safety standards and minimize the risk of fire hazards. By following the guidelines in this article, manufacturers can create safe and reliable power strips that are essential in modern electrical systems.
