Nsfs - 347 2021 ((new))
Note: If "NSFS" refers to a different specific standard (e.g., a non-Nigerian food safety specification), please provide the issuing body. The following review is based on the widely recognized NFS 347:2021 (Nigerian Food and Drink Standard for Carbonated Soft Drinks).

Practical implications for stakeholders
- Manufacturers: pathway to market differentiation and access to sustainability‑oriented specifiers; requires investment in testing, data collection, and possible reformulation.
- Architects/specifiers/owners: a verified data source to compare membrane options beyond performance specs; helps meet procurement/green rating requirements.
- Installers/recyclers: potential growth in recycling/take‑back programs and demand for documented end‑of‑life pathways.
What Is NSF/ANSI 347?
NSF/ANSI 347 is a American National Standard that establishes sustainability requirements for single-use food service items – think plates, bowls, cups, lids, straws, cutlery, and takeout containers. The 2021 edition updated criteria for compostability, recycled content, and responsible sourcing. Note: If "NSFS" refers to a different specific standard (e
Developed by NSF International in collaboration with stakeholders (brands, recyclers, labs, and NGOs), this standard isn’t just about “green” claims. It’s a third-party audited certification. Review: NFS 347:2021 – Standard for Carbonated Soft

1. Material Safety – Extraction Testing
Gaskets are submerged in synthetic water (pH adjusted, chlorinated) at elevated temperatures for 72–168 hours. The resulting leachate is analyzed for:
- Heavy metals (lead, cadmium, mercury, arsenic)
- Volatile organic compounds (VOCs)
- Semi-volatiles (bisphenols, phthalates)
- PFOS and PFOA (< 70 ppt combined)
Maximum allowable contaminant limits are set by NSF/ANSI 61 (for drinking water) and NSF/ANSI 600 (for wastewater).
