The National Standard for Food Safety (NSFS) 347 2021 is a critical document that outlines the requirements for food safety management in Australia. As a food business operator, it's essential to understand the guidelines and regulations set out in this standard to ensure compliance and maintain the highest level of food safety.
To achieve certification, manufacturers must undergo an intensive third-party evaluation and plant audits conducted by NSF. Products are scored based on a distributed across five core categories: Assessment Category Maximum Points Key Evaluation Criteria Product Design
NSF/ANSI 347 (published 2021) is a voluntary sustainability standard and third‑party certification protocol for single‑ply roofing membranes. It sets criteria across material health, product efficiency, manufacturing, supply chain transparency, and end‑of‑life to help roof membrane manufacturers demonstrate reduced environmental and social impacts and support sustainable building rating systems.
The assessment typically awards points based on criteria such as: Product Design nsfs 347 2021
Demystifying NSF/ANSI 347: The Ultimate Guide to Sustainable Single-Ply Roofing Membranes
Focuses on the use of environmentally responsible materials and the overall recyclability of the membrane.
The standard is more than a certification; it is a roadmap for the roofing industry to create better, more sustainable products. By adhering to these strict guidelines, manufacturers are encouraged to innovate in material science and production, resulting in roofing systems that are not only durable and effective but also environmentally responsible.

Manufacturers achieve certification based on their total point score: Minimum 35 points Silver: Minimum 45 points Gold: Minimum 56 points Platinum: Minimum 75 points
Major municipal water departments (e.g., Los Angeles Department of Water and Power, New York City DEP, Toronto Water) now explicitly require in their specifications. Contractors using older-certified gaskets face immediate rejection and potential blacklisting.
For architects and specifiers, NSF/ANSI 347 serves as a valuable tool for selecting sustainable roofing products, which can contribute points toward green building certifications like LEED. For manufacturers, certification to NSF/ANSI 347 provides an objective and transparent way to validate the sustainability of their products and differentiate themselves in the marketplace.
