Nsfs 347 2021 May 2026

NSF/ANSI 347 serves as a premier sustainability standard for evaluating the lifecycle impacts of resilient flooring materials, often updated for 2021 [12]. The standard certifies products at Silver, Gold, or Platinum levels based on factors including raw material sourcing, manufacturing practices, and end-of-life management [12].

2. Physical & Mechanical Properties

• Tensile strength – Minimum 6.9 MPa (1000 psi) for most elastomers.
• Compression set – ≤ 25% after 22 hours at 125°C.
• Hardness – Shore A must be within ±5 points of manufacturer claim.
• Creep relaxation – ≤ 20% torque loss after 1000 hours at 80°C under constant strain.

Encouraging the use of recycled content and the reduction of hazardous chemicals during the formulation phase. Product Manufacturing: nsfs 347 2021
