Which organization sets standards for low pressure equipment certification?

The National Fire Protection Association (NFPA) is responsible for setting standards related to fire safety and prevention, which includes regulations and guidelines for various types of equipment, including low pressure equipment. These standards help ensure that equipment is designed and maintained to prevent fire hazards, protect users, and comply with safety regulations. In the context of low pressure equipment certification, NFPA establishes criteria that must be met to ensure that these systems operate safely and reliably.

The other organizations mentioned have different focuses, such as environmental protection, transportation regulations, or healthcare practices, and do not specifically address the certification standards for low pressure equipment. This is why NFPA is the relevant authority in this area.
