- Health and safety bodies
- Quality control personnel
- Test Laboratories
Why should you use BS EN 14175-3 - Fume cupboards?
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.
