What does the term "Approved" signify in the context of National Fuel Gas Code?

In the context of the National Fuel Gas Code, the term "Approved" signifies that a certain item, material, or procedure has been deemed acceptable by the Authority having jurisdiction. This authority is usually a local government entity or organization responsible for enforcing compliance with safety regulations and standards in the area where the gas installations are being conducted.

An item marked as "approved" means it meets the required standards and regulations as interpreted by this authority. This designation helps ensure that the materials and practices used in gas-related installations are safe and compliant with local codes, contributing to overall public safety and effective gas system performance. It is a key element in the verification process for installations, fostering a clear understanding of which products and methods can be utilized within the jurisdiction's regulatory framework.

The other choices provide alternative contexts for the significance of "approved" but do not align directly with the specific use of the term in gas code regulations. Being verified by a government entity, recommended for safety compliance, or certified by a third-party organization may also involve safety considerations but do not encapsulate the full scope of what "approved" implies in terms of jurisdictional authority and regulatory compliance.
