NBR – Full Cleaning Validation Description NBR Cleaning Validation Coupons are designed to represent NBR (Nitrile Butadiene Rubber, Buna‑N) Cleaning Validation Coupons simulate oil‑resistant elastomer surfaces used in gaskets, hoses and seals. NBR offers excellent resistance to oils, solvents and fuels. Ideal for validating cleaning of chemically exposed rubber MoCs.. They are used in pharmaceutical, bioprocess, and GMP-regulated systems to assess residue recovery, detergent compatibility, and cleanability of equipment surfaces made from NBR. These coupons support RF% studies, swab and rinse recovery validation, and regulatory documentation for cleaning procedures involving this material of construction. ✔ KEY PURPOSES • Establish residue recovery factors (RF%) for NBR surfaces • Validate swab and rinse recovery in GMP cleaning procedures • Assess chemical compatibility with detergents and disinfectants • Provide FDA/EMA/PIC/S-compliant cleaning validation documentation • Ensure robust justification for equipment made from NBR ✔ MATERIAL CHARACTERISTICS • Material behaves as described in its summary: NBR (Nitrile Butadiene Rubber, Buna‑N) Cleaning Validation Coupons simulate oil‑resistant elastomer surfaces used in gaskets, hoses and seals. NBR offers excellent resistance to oils, solvents and fuels. Ideal for validating cleaning of chemically exposed rubber MoCs. • Suitable for RF% reproducibility • Stable under standard cleaning conditions ✔ FORMATS • 50×50 mm or 75×75 mm validation plates • 2–5 mm construction depending on material
