NFS 347:2021 represents a critical update to Nigeria's regulatory framework for one of the most consumed beverage categories—carbonated soft drinks (CSDs). The standard aims to protect public health, ensure fair trade, and align local production with international food safety benchmarks (e.g., Codex Alimentarius). However, its success depends entirely on SON's enforcement capacity.

Gaskets are submerged in synthetic water (pH adjusted, chlorinated) at elevated temperatures for 72–168 hours. The resulting leachate is analyzed for: nsfs 347 2021
Maximum allowable contaminant limits are set by NSF/ANSI 61 (for drinking water) and NSF/ANSI 600 (for wastewater).
Another significant aspect of NSF's work is its support for research and innovation. Through funding grants for research projects, the NSF enables scientists and engineers to explore new ideas, conduct experiments, and develop technologies that can lead to breakthroughs in various fields. This support not only contributes to the body of knowledge in specific areas but also has the potential to lead to practical applications that improve people's lives and drive economic growth.

If you work in food service, manufacturing, or environmental compliance, you’ve likely heard the push for eco-friendly packaging. But what actually certifies a disposable cup or clamshell as “sustainable”? Enter NSF/ANSI 347 (2021) – the benchmark for single-use food service items. Maximum allowable contaminant limits are set by NSF/ANSI
Here’s everything you need to know about this quietly powerful standard.
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 NSF also places a strong emphasis on addressing global challenges. This includes funding research on climate change, developing sustainable solutions for energy and environmental issues, and creating technologies that can improve health outcomes. In 2021, as in other years, the NSF likely supported numerous projects focused on these and other pressing global issues.
NSFS 347-2021 establishes the minimum requirements for mechanical couplings used to join thermoplastic pressure piping systems. This includes pipes made from materials such as PVC, CPVC, PE, and PP. The standard is critical for ensuring the safety, reliability, and performance of alternative joining methods to traditional solvent cementing or heat fusion. It covers material requirements, design criteria, performance testing, and marking requirements.
