NSF 347 is a standard developed by the National Sanitation Foundation for commercial food equipment. The standard provides guidelines for the design, construction, and testing of equipment used in foodservice establishments, such as restaurants, cafes, and food courts. The standard covers a wide range of equipment, including dishwashing machines, cooking equipment, refrigeration units, and food preparation surfaces.
NSF/ANSI 347 is the leading sustainability assessment for single-ply roofing membranes, providing a verifiable framework for architects and specifiers to select environmentally responsible building materials. Unlike single-attribute claims, this standard evaluates a product's entire life cycle—from raw material extraction to end-of-life management. Core Assessment Categories
“If the machine heats water, sanitization is guaranteed.” Reality: A machine may reach 180 °F in the tank but fail to maintain that temperature at the spray arms. NSF certification requires performance testing throughout the entire sanitization cycle, not just heating capability. nsfs 347 work

The goal of the standard is to provide architects and specifiers with a reliable way to identify roofing materials that reduce environmental impact while maintaining high performance. NSF 347 is a standard developed by the
NSF/ANSI 3 applies to commercial dishwashing, glasswashing, and pot‑washing machines that use spray systems and hot water or chemical sanitizing solutions. The standard establishes minimum requirements for material safety, design, construction, and product performance to ensure good sanitation.
