Introduction
Purchasing cleanroom wipes in bulk is a significant decision. To prevent costly contamination issues, buyers in Western markets should perform key acceptance tests: particle release, non-volatile residue (NVR), absorbency, and compatibility with solvents used onsite.
Essential Performance Tests
Particle generation tests: Quantify particles released during wiping under controlled conditions.
Extractables/NVR: Measure ionic and organic residues left after wiping—critical for semiconductor and pharmaceutical uses.
Absorbency & release: Evaluate how much solvent the wipe holds and whether it releases contaminants when saturated.
Linting & visual inspection: Ensure edge sealing and fiber stability.
Supplier Audit Checklist
Request lot certificates, ISO/IEST compliance evidence, and production site photos. Visit suppliers or conduct third-party audits when possible. Confirm packaging methods for contamination control and traceability systems.
Field Trials
Run a pilot in your own process environment: use candidate wipes in routine cleaning and monitor particulate counts, equipment cleanliness, and operator feedback. Data from field trials often reveals real-world performance differences.
Conclusion
Rigorous testing and supplier due diligence reduce risk and optimize long-term cost. For critical Western manufacturers, a validated wipe selection improves product quality and simplifies regulatory compliance.
