Safe Handling and Unboxing Guide for Particle Standards
Unlike standard laboratory supplies, unboxing a NIST-traceable particle standard is a high-stakes procedure where a single speck of ambient dust can instantly ruin a critical calibration baseline. The moment you break the shipping seal, sensitive PSL spheres face immediate risks from static aggregation, thermal shock, and cleanroom cross-contamination. Safeguarding your data accuracy requires a strict, […]
ISO 14644-3 Test Methods: Airborne Particles, Flow, and Visualization Studies
Introduction: Proving Cleanrooms Perform as Designed Designing a cleanroom is one thing. Proving it performs according to ISO 14644-3 test methods is another. From airborne particle counting to airflow visualization studies, ISO 14644-3 ensures facilities meet their classification and regulatory expectations. Part 1: Core Test Categories Airborne Particle Counts: Calibrated using PSL standards. Airflow Visualization: […]
