What are regulatory documents that outline the requirements for CNG operations referred to as?

Regulatory documents outlining the requirements for CNG operations are referred to as codes and standards because they provide a formal set of guidelines and specifications that must be followed to ensure safe and efficient operation within the industry. These codes and standards are established by recognized organizations and govern various aspects of CNG operations, including installation, maintenance, and safety measures. Compliance with these documents is crucial for ensuring that CNG operations adhere to legal requirements, promote safety, and protect public health and the environment.

While terms like safety guidelines, regulatory frameworks, and industry regulations may touch on aspects of CNG operations, they typically do not encapsulate the comprehensive and formalized nature of codes and standards. Codes and standards are legally binding and provide specific guidance that must be followed, making them the most accurate descriptor for the regulatory documents in question.
