What is UL 941:1990

UL 941:1990 is a technical standard that specifies safety requirements for self-contained, non-refillable gas containers known as “reliable fuel-fired appliances.” This standard outlines the minimum construction and performance criteria that these appliances must meet to ensure safe operation.

The Purpose of UL 941:1990

The primary purpose of UL 941:1990 is to prevent explosions or fires caused by the leakage of gas from fuel-fired appliances. It aims to protect consumers and property by setting regulations that reduce the risks associated with gas-powered devices.

In order to achieve this goal, UL 941:1990 establishes guidelines for the material composition, fabrication, and testing procedures of reliable fuel-fired appliances. By adhering to these standards, manufacturers can produce appliances that are deemed safe for use in domestic and commercial settings.

Key Requirements of UL 941:1990

One of the key requirements set forth by UL 941:1990 is the use of specific materials that have been proven to be resistant to gas leakage. The standard also mandates the presence of safety devices such as pressure relief valves and automatic shut-off mechanisms.

Additionally, UL 941:1990 stipulates that reliable fuel-fired appliances must undergo rigorous testing procedures to assess their safety and operational capabilities. These tests include measures to evaluate the response to excessive temperatures, high pressures, and extreme environmental conditions.

Conclusion

UL 941:1990 plays a crucial role in ensuring the safety and reliability of fuel-fired appliances. By establishing minimum requirements for construction and performance, it reduces the risks associated with gas leakage, explosions, and fires, providing peace of mind to both manufacturers and consumers. Adherence to this standard helps create a safer environment in homes, offices, and other establishments that utilize these appliances.
