347 Work — Nsfs

Here is a breakdown of each key area, what it measures, and its point allocation:

To achieve third-party certification, a manufacturer must fulfill baseline prerequisite requirements and earn points across . The total point allocation reflects the standard's heavy emphasis on the operational longevity of the roof alongside its manufacturing impacts. nsfs 347 work

The standard uses a tiered point system (Silver, Gold, and Platinum) to score products across five key areas: Here is a breakdown of each key area,

The standard simplifies the complex task of selecting sustainable roofing products. Instead of juggling multiple, sometimes conflicting single-attribute claims, architects can now specify a product with a certified, easy-to-understand rating (e.g., "Certified Gold to NSF/ANSI 347"). This allows them to confidently meet the material sustainability requirements of green building rating systems like LEED, Green Globes, and the International Green Construction Code (IgCC) . By including NSF/ANSI 347 certification in project specifications, architects can ensure that the roofing work contributes directly to the project's overall sustainability goals. : It provides a framework for architects and

: It provides a framework for architects and specifiers to compare products based on documented performance and life-cycle assessments (LCA). 2. The Scoring Framework

| Task | Why It Matters | | :--- | :--- | | | Prevents debris from re‑depositing on dishes and blocking drains. | | Inspect spray arms for blockage | Clogged nozzles cause poor wash results and wasted water. | | Wipe wash and rinse arms | Removes grease and mineral buildup that can restrict water flow. | | Check curtains/doors for damage | Damaged seals allow heat and chemical loss, reducing sanitization effectiveness. | | Verify final rinse temperature (heat systems) | A drop below 180 °F means dishes are not properly sanitized. | | Verify sanitizer ppm (chemical systems) | Incorrect chemical concentration leads to unsanitary dishes. | | Inspect drain flow | Slow drainage indicates a blockage that will soon overflow. | | Drain and clean tanks at end of shift | Stagnant wash water breeds bacteria and creates odors. | | Wipe interior walls | Removes biofilm and grease films. | | Leave doors open overnight | Promotes drying, preventing mold and bacterial growth inside the machine. |
