Which organization’s standards must all equipment and appurtenances for LP-gas service meet?

The correct answer focuses on the requirement for all equipment and appurtenances used in LP-gas service to meet standards set by a nationally recognized testing laboratory. This means that the equipment must undergo rigorous testing and certification by an organization that is recognized as adhering to specific safety and performance standards. These standards ensure that all components perform safely and effectively in handling LP-gas, which is crucial for minimizing risks associated with gas leaks, explosions, and other hazards.

Nationally recognized testing laboratories have established protocols and criteria that equipment must satisfy before it can be deemed compliant for LP-gas service. This compliance is essential as it ensures that the equipment can withstand the pressures and conditions inherent in LP-gas systems, ultimately safeguarding both users and the environment.

In contrast, the other organizations mentioned do not specifically cater to the regulation and certification of LP-gas equipment. For example, the American National Standards Institute is involved in the development of voluntary consensus standards but does not directly test and certify equipment. The Environmental Protection Agency focuses on environmental protection and regulations, while the International Bureau of Standards plays a role in international standardization but is not specific to LP-gas safety standards. Thus, the importance of certification by a recognized testing laboratory stands out, ensuring recognized safety and performance
