What is UL 60335-2-65?

UL 60335-2-65 is a technical standard that focuses on the safety requirements for combustion engines used in various applications. This standard, developed by Underwriters Laboratories (UL), defines guidelines and testing procedures to ensure the safe operation of equipment utilizing combustion engines.

Scope of UL 60335-2-65

The scope of UL 60335-2-65 covers a wide range of equipment, including but not limited to lawnmowers, chainsaws, generators, and snowblowers. It applies to any equipment that incorporates an internal combustion engine as a power source. The standard provides specific safety requirements related to these engines, such as fuel systems, exhaust emissions, and ignition protection.

Key Safety Requirements

One of the key safety requirements outlined in UL 60335-2-65 is the establishment of adequate safeguards to prevent fuel leakage. The standard mandates that equipment must be designed and constructed in a way that minimizes the risk of uncontrolled fuel spills. Additionally, it specifies the need for robust fuel containers and caps to prevent accidental fuel ignition.

Another important aspect addressed by UL 60335-2-65 is the control of exhaust emissions. The standard sets limits on the level of pollutants emitted by combustion engines to mitigate environmental impact and enhance user safety. It requires manufacturers to implement proper emissions control technologies, such as catalytic converters and engine tuning, to achieve compliance.

Compliance and Certification

Manufacturers must ensure that their equipment meets the requirements stated in UL 60335-2-65 before placing it on the market. Compliance with this standard is typically demonstrated through testing conducted by accredited laboratories. Once the equipment passes these tests, it can be certified and labeled accordingly, indicating its adherence to the safety standards outlined in UL 60335-2-65.

Compliance with UL 60335-2-65 is essential for both manufacturers and end-users. For manufacturers, ensuring compliance demonstrates commitment to producing safe and reliable products. For end-users, purchasing equipment that meets this standard provides peace of mind regarding its operational safety.
