UL1155 is a technical standard that defines the safety requirements for power-supply cords used in various electrical and electronic products. This standard, developed by Underwriters Laboratories (UL), ensures that power cords meet specific criteria to ensure their safety and performance.
Importance of UL1155
UL1155 plays a crucial role in ensuring the safety of users and preventing potential hazards associated with power cords. It sets guidelines for manufacturers to follow during the design and production of power cords, ensuring they are resistant to electrical shocks, high temperature, impact, and other environmental conditions.
Key Requirements of UL1155
Under UL1155, power cords are tested for various factors including electrical resistance, insulation resistance, flexibility, durability, and plug and connector integrity. In addition, the standard specifies requirements for marking, labeling, and documentation, allowing for proper identification and traceability of compliant power cords.
Compliance and Certification
To demonstrate compliance with UL1155, manufacturers undergo rigorous testing and evaluation of their power cords. Once the power cords meet all the required criteria, they receive certification from UL, indicating that they have met the standard's safety requirements. Buyers can look for the UL mark on power cords as a guarantee of safety and quality.
