BS EN IEC 61591:2020+A11:2020

What is BS EN IEC 61591 about?

BS EN IEC 61591 discusses the methods for measuring the performance of cooking fume extractors BS EN IEC 61591 defines the main performance characteristics of these appliances, which are of interest to the user, and specifies methods for measuring these characteristics.

Note 1: BS EN IEC 61591 applies to cooking fume extractors incorporating a fan for the recirculation or extraction mode situated in a household kitchen.

Note 2: BS EN IEC 61591 used for cooking fume extractors where the fan is mounted separately from the appliance, but controlled by the appliance when the fan is defined in the technical documentation (e.g., name plate data) and instructions for installation.

Note 3: BS EN IEC 61591 deals also with down-draft systems arranged besides, behind or under the cooking appliance.

Note 4: BS EN IEC 61591 does not specify a classification or ranking for performance.

Note 5: BS EN IEC 61591 does not deal with safety requirements. 

Who is BS EN IEC 61591 for?

BS EN IEC 61591 on the performance of cooking fume extractors is useful for:

• Cooking fume extractors manufacturers and suppliers
• Quality control laboratories
• Cooking fume testers
• Safety and regulatory bodies
