Services

From third-party cleanroom certification to HVAC airflow balancing, microbiological monitoring, and airflow visualisation, we deliver a full suite of controlled-environment testing to ISO 14644 and NEBB standards. Each service is calibrated to the regulatory, safety, and operational demands of Singapore's pharmaceutical, semiconductor, and healthcare facilities.

  1. 01

    Cleanroom Certification & Performance Testing

    ISO 14644-1 classification, ISO 14644-2 monitoring, and ISO 14644-3 test methods — non-viable particle counts, recovery tests, pressure cascades, and HEPA installation leak tests, delivered as peer-reviewed certification reports.

  2. 02

    Clean Air Equipment Testing

    Face velocity, HEPA integrity via PAO/DOP aerosol challenge (IEST-RP-CC034), containment testing per NSF/ANSI 49, and smoke-pattern visualisation — covering laminar flow cabinets, clean booths, biological safety cabinets, fume hoods, and isolators.

  3. 03

    HVAC Airflow Measurement & Balancing

    NEBB-certified procedures for air-change-rate calculation, pressure-differential verification, and multi-point Pitot-traverse balancing — ensuring supply, return, and exhaust conform to facility design intent and GMP operational envelopes.

  4. 04

    Microbiological & Air Quality Monitoring

    Viable sampling via settle plates and active air impaction (TSA/SDA), contact-plate swabbing, non-viable particulate counts per ISO 14644-1, and SS554 indoor air quality — CO₂, CO, formaldehyde, VOCs, and particulates for pharmaceutical, healthcare, and educational environments.

  5. 05

    Compressed Dry Air & Process Gas Testing

    Dewpoint, oil aerosol, oil vapour, particulate, and microbiological verification to ISO 8573-1 purity classes — validating the compressed air, nitrogen, and process gases feeding your critical production environments.
