HCHC – Full Cleaning Validation Description HCHC Cleaning Validation Coupons are designed to represent HCHC high-carbon, high-chromium alloy coupons simulate hardened tool steel surfaces used in pharma cutting, granulation and contact tooling. Extremely wear-resistant and moderately corrosion‑resistant. Ideal for swab recovery and validating cleaning of high-hardness steel surfaces.. They are used in pharmaceutical, bioprocess, and GMP-regulated systems to assess residue recovery, detergent compatibility, and cleanability of equipment surfaces made from HCHC. 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 HCHC 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 HCHC ✔ MATERIAL CHARACTERISTICS • Material behaves as described in its summary: HCHC high-carbon, high-chromium alloy coupons simulate hardened tool steel surfaces used in pharma cutting, granulation and contact tooling. Extremely wear-resistant and moderately corrosion‑resistant. Ideal for swab recovery and validating cleaning of high-hardness steel surfaces. • 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
