A laboratory fume cupboard is a very complex product subjected to a wide range of demanding tests. Your fume cupboard must comply with all the testing and verifications as determined by the applicable standards, and it is the responsibility of the manufacturer to state most of the technical data in the accompanying technical documentation.

• Retention capability (efficiency) using SF6 gas
• Robustness of the retention capability
• Flow
• Air exchange capacity
• Pressure loss
• Sliding window test
• Air flow indicator functionality and accuracy
• Construction and materials used
• Intensity of illumination
• Worktop strength
• Dimensions
• Basic safety and purposefulness of design
• Media supply and sewage system
• Noise level
• Electrical installations
• Accompanying technical documentation

WHAT IS ASSESSED:

• Accompanying documents (drawings, material data sheets of components - safety glass, worktop material, closing valves, etc.).
• Declaration of Conformity
• Marking (obligatory data)

MOST FREQUENT PROBLEMS:

• The manufacturer is unaware of the parameters of the laboratory fume cupboards produced.
• Incomplete accompanying technical documentation

STANDARDS:

• ČSN EN 14175-2 Fume cupboards.  Safety and performance requirements
• ČSN EN 14175-3 Fume cupboards.  Type test methods
• ČSN EN 14175-4 Fume cupboards . On-site test methods
