THE COMMISSIONING phase begins post-construction and concentrates on qualifying all systems and their functionality.

For a Pharmaceutical application this will form part of the Installation (IQ) and Operational Qualification (OQ). For all other industries a standard commissioning plan will be drafted and test certificates will be produced alongside a detailed Operational & Maintenance (O&M) manual.

The commissioning plan will cover a series of verification checks on key components, systems and plant – such as HVAC, electrical, network, lighting, EMS, BMS and other critical utilities. The cleanroom performance will be verified through ISO 14644 validation and associated testing.

HVAC

  • Airflow supply and velocities
  • Chilled water flow rates, temperatures and valve set points
  • Room temperature and humidity check
  • Air on and air off coil temperatures
  • Frost protection checks
  • Heater loading tests
  • Probe calibration, location and offset
  • Fan speed, inverter and electrical checks
  • System pressure testing

ELECTRICAL

  • Continuity testing
  • Insulation resistance testing
  • Polarity
  • Resistance testing (measuring Zs)
  • RCD checks

NETWORK

  • LAN continuity testing

BMS

  • Software validation
  • Hardware verification and calibration

EMS

  • Transmitter/probe calibration (UKAS)
  • CF21R Part 11 compliance (if required)

LIGHTING

  • LUX level verification
  • Emergency lighting testing

PLUMBING

  • Pipework pressure & drainage testing

COMPRESSED AIR & GASSES

  • Air purity & oil-free test ISO8573-1:2010
  • Pressure, micro-organism, moisture testing

EXTRACTION

  • Airflow & velocity measurements

SEPARATIVE DEVICES

  • Particulate, airflow, filter integrity testing
  • Optional: temperature, KI-discus, velocity

FIRE ALARM

  • BS5839-1 operational testing
