Method & scope. Analysis performed on a representative sample of the material removed during the cleaning service on the date shown, using standards-referenced laboratory methods (including ISO 8502-9 for soluble ionic contamination and associated procedures). Formaldehyde and TVOC values are offgassing readings measured from the collected dust sample. “Typical environment” comparisons are drawn from Technology Care reference data. This certificate characterises the material removed during the service; it is not an assessment of the remaining surfaces, indoor air, or occupant health, and is not a regulatory clearance. Verify at cleancertify.com using the certificate number above.

Method & scope. Analysis performed on a representative sample of the dust removed during the cleaning service on the date shown. Soluble chloride content was determined by conductometric analysis (per the principles of ISO 8502-9) and is expressed as a percentage of the collected dust by mass; surface conductivity classified per EOS/ESD-S4.1; pH measured on the collected residue. Conductive metallic debris was assessed by optical microscopy (zinc whiskers) and magnetic separation (ferrous particles), the ferrous fraction expressed as a percentage of the collected dust by mass. Chloride is the principal driver of ionic corrosion and leakage currents in electronic installations — the larger its share of the removed dust, the more corrosion and ESD risk was taken off your equipment.
