BS EN 14175 discusses fume cupboards. BS EN 14175-3 is the third part of BS EN 14175 multi-series and discusses type test methods.
BS EN 14175-3 specifies type test methods for the assessment of safety and performance of fume cupboards connected to an exhaust air system. Relevant requirements are specified in EN 14175-2. For terms and their definitions, EN 14175-1 applies. For safety and performance requirements of fume cupboards, EN 14175-2 applies. For on-site test methods of fume cupboards, EN 14175-4 applies. For the type testing and on-site testing of variable air volume (VAV) fume cupboards, EN 14175-6 applies in addition to BS EN 14175-3. For fume cupboards for high heat and acidic load, EN 14175-7 applies.
Note 1: For the testing of recirculation filtration fume cupboards, EN 17242: —1 applies
Note 2: For the testing of microbiological safety cabinets, EN 12469 applies.
BS EN 14175-3 on fume cupboards is useful for:
Fume cupboards are used widely in laboratories and are designed to capture and remove air-borne hazardous substances generated during laboratory experiments (e.g., gases, vapours, aerosols, and particulates/dust). Work with substances that produce/generate toxic or harmful fumes, vapours, gases, dust, or chemical aerosols should be carried out in a fume cupboard to eliminate or reduce the risk of exposure to an acceptable and safe level.
BS EN 14175-3 provides you with the test to assess the safety and performance of fume cupboards connected to an exhaust air system. BS EN 14175-3 guides you with test rooms and general test conditions. BS EN 14175-3 guides you with airflow tests that include extract volume flow rate, containment, the robustness of containment, air exchange efficiency, and pressure drop.
BS EN 14175-3 also guides you with sash tests which include sash suspension test, sash displacement test, protection against splashes, sash stop, and alarm test. BS EN 14175-3 provides you with airflow indicator tests and construction and materials tests. BS EN 14175-3 helps you manufacture high-quality fume cupboards.
