EN 14175 fume cupboards: identify the relevant part
A request that says only “EN 14175” is incomplete. The series separates subjects including terminology, safety and performance requirements, type-test methods and on-site tests. Other parts address installation and maintenance or particular operating arrangements.
Use the exact part number, edition and scope from the project specification. The BSI installation and maintenance catalogue entry illustrates why a general series reference needs to be made specific. The full standard and the designer’s requirements should guide the formal assessment.
Keep any required evidence attached to the model and configuration being proposed. Similar-looking cupboards can have different sashes, controls, internal fittings or ventilation requirements.
Type tests and on-site tests
| Evidence | Main purpose |
|---|---|
| Type testing, Part 3 | Assess a defined cupboard design in a controlled test arrangement. |
| On-site testing, Part 4 | Assess the cupboard in its installed setting using the specified methods. |
| Installation and maintenance information | Define the conditions and ongoing care needed for the installation. |
Type-test documentation helps a specifier understand a design. The installed room introduces supply-air outlets, doors, people, furniture and an actual extract system. Those conditions deserve their own attention.
Before comparing reports, check that the model, sash arrangement, opening and airflow conditions match. If a proposed accessory or internal apparatus changes the tested configuration, ask the supplier and project adviser what further assessment is needed.
What a containment report should let you understand
A report should allow the reader to connect the test result to the installation. Look for the cupboard identification, applicable method, sash opening, airflow or ventilation settings and the recorded test conditions. Retain the observations that explain unusual results.
Different parts of the assessment examine different aspects of performance. An inward airflow reading is not a complete substitute for containment evidence, and a design test does not describe every future laboratory use. The responsible specialist should explain which tests address the project's hazards and operating arrangements.
When a result is unclear, ask a precise question: which configuration was tested, which requirement was used, and what change would require another check? That is more useful than comparing two unexplained pass labels.
Plan the installation around the tested arrangement
Keep supply-air jets and busy circulation routes in the room-layout discussion. Provide enough space for the intended sash operation and safe access to controls. Show the designer the apparatus that will sit inside the cupboard, especially large items that may alter internal airflow.
The fan and ductwork must meet the required duty as a system. Record the intended operating conditions and the settings established during commissioning. Our fume cupboard installation planning guide helps organise the building, services and access information before work begins.
For variable-air-volume arrangements, specify how the controls respond to sash movement and how that response will be verified. A control-system label alone does not document the installed performance.
Use the right New Zealand reporting pathway
The building compliance schedule remains central to the inspection and maintenance of an SS11 laboratory fume cupboard. Ask the project team how the EN 14175 evidence, commissioning information and local reporting requirements fit together.
We provide SS11 fume cupboard testing and servicing. Give us the actual specification so the requested scope is clear. Where a document also calls for ASHRAE 110 testing evidence, keep the methods and acceptance criteria individually identified.
After a change to the cupboard, room ventilation or process, update the operating information and seek advice on the verification needed. This overview supports specification planning; it does not replace a project-specific compliance assessment.
Questions about en 14175
Does EN 14175 specify one universal airflow for every cupboard?
Use the requirements and operating conditions specified for the cupboard and project. The series covers more than a single airflow number.
What should I send with an EN 14175 enquiry?
Send the required part and edition, the cupboard model and configuration, the room layout and the evidence your project team needs. Include any existing reports.
