Brass – Full Cleaning Validation Description Brass Cleaning Validation Coupons are designed to represent Brass 353 Cleaning Validation Coupons represent high-leaded free-machining brass surfaces. They simulate precision-turned parts, valves, fittings and threaded components. Brass 353 offers excellent machinability and stable residue recovery characteristics. Useful for validating cleaning of high-lead brass contact parts under GMP. Ideal for swab and rinse recovery studies on free-machining brass components.. They are used in pharmaceutical, bioprocess, and GMP-regulated systems to assess residue recovery, detergent compatibility, and cleanability of equipment surfaces made from Brass. 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 Brass 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 Brass ✔ MATERIAL CHARACTERISTICS • Material behaves as described in its summary: Brass 353 Cleaning Validation Coupons represent high-leaded free-machining brass surfaces.
