Ventilation System Testing

Whatever type of ventilation system was installed within your buildings, regular ventilation system testing is essential, but when it comes to specialist ventilation systems, bringing clean, uncontaminated air to clean environments and highly sensitive people, processes or products, it can be critical.

Robin sanat Hounam can carry out ventilation system testing for all types of specialist ventilation systems – from fume cupboards and local exhaust ventilation (LEV) through to systems for use in clean rooms, laboratories, hospitals, and schools.

We provide ventilation system testing by fully qualified professionals.

Fully qualified to carry out testing to all current regulatory standards, including ISO 14644, EU GMP, IEST-RP-CC006.3, local codes.

For other corporate standards, you can rely on Robin Sanat Hounam (RSH) for an end to end service from professionals who understand the unique needs of operations using specialist ventilation systems.

Hospital Ventilation System Testing

The ventilation systems within hospitals can have a critical impact, especially in areas such as operating theatres, intensive care units and category 3 and 4 laboratories.

Here we will work to Iran Ministry of Health Standard for planning and design of SAFE HOSPITAL & HTM 03-01 specifications, verifying air handling plant, taking air change rate measurements, testing room differential pressure and carrying out bacteriological sampling.

Local Exhaust Ventilation System Testing

For all LEV systems, we work to the requirements of HSG 258(Third Edition, 2017).

Qualitative assessments include the observation of airflow patterns, visual examination of system components, and assessing the suitability of the system for the process it is used for.

Quantitative assessments carried out include airflow velocity measurements (capture velocity, face velocity, and duct velocity), static duct pressure measurements, filter performance testing, and sound and lighting levels.

Fume Cupboard Testing

Both ducted and recirculating fume cupboards work to draw air away from the open end of the cupboard and expel it either into the outside environment or through filters and back into the room.

School Fume Cupboards

These are tested to the requirements of local safety codes including:

. A visual examination of the fume cupboard and extract system

. Face velocity measurements

. Light level check

. Mechanical inspection of sash system (low stop, high lock, pulleys, weights, cords etc)

. Mechanical control of fan unit (motor, bearings, drive belts)

. Mechanical check of installed services

. Filter saturation test of carbon filters using sulfur dioxide gas

Industrial Fume Cupboards (Ducted)

Here we will carry out commissioning tests to the requirements of BS EN 14175 Part 4, including:

. Visual inspections of the sash, protection of slashes, the sash suspension and stops, services, materials, pressure relief, and accessibility of construction parts

. Face velocity

. Extract volume flow

. Pressure drop

. Airflow visualisation

. Room air velocity

. Alarm system

. Containment

. Sound pressure measurement

Additional routine testing to the requirements of BS EN 14175 Part 5 includes the sash suspension and sash stop, protection against splashes, cleanliness of the fume cupboard and baffles, the integrity of the mechanical assembly, pressure relief, airflow and the VAV system, indicator function or sensor response, leakages, hygiene, services, illumination, noise, electrical isolation and fire alarm devices if appropriate.

CL3 and CL4 Containment Laboratories

As well as HSG 258, performance requirements are checked for compliance with the HSE’s Advisory Committee on Dangerous Pathogens (ACDP)’s 2001 publication ‘The management, design, and operation of microbiological containment laboratories.' These checks include:

. Visual inspection of the ventilation system

. Measurement of airflow rates and calculation of air changes

. Measurement of room pressure differential

. Leak tightness test

. Room sealability test

. HEPA filter integrity testing

. Inspection and testing of control and alarm systems

Microbiological Safety Cabinet Testing

All microbiological safety cabinets are tested to the requirements of BS EN 12469, including:

. Retention at the front aperture type testing using microbiological or KI methods, and installation testing to check that the manufacturer’s specification is met, volumetric airflow rates, airflow patterns and retention.

. Leak tightness of carcass is type tested using a soap solution.

. Filters are type tested, and installation tested using the aerosol challenge method, and for installation testing the natural aerosol challenge method is also used where appropriate.

. Product protection is type tested using the microbiological method, and for installation testing, we will check that the manufacturer’s specification is met, volumetric airflow rates, airflow patterns, and retention.
