Overview

EN 61591:1997/A1:2006 is a European standard developed by CLC that specifies the methods for measuring the performance of household range hoods and other cooking fume extractors. It is an amendment to the original EN 61591:1997, aligning with the international IEC 61591:1997/A1:2005 standard. This document sets out standardized test procedures to assess parameters such as airflow rate, grease absorption, odour extraction, noise levels, and other performance characteristics.

This standard is vital for manufacturers, testing laboratories, and regulatory authorities to ensure consistent evaluation of cooking ventilation products. It enhances product reliability and consumer safety by offering clear measurement guidelines, including for range hoods equipped with external blowers.

Key Topics

• Scope and applicability:

  • Applies to household range hoods and cooking fume extractors.
  • Includes provisions for range hoods with external blowers controlled by the unit.
  • Covers installation requirements based on manufacturer instructions.

• Definitions:

  • Clarifies terms like "grease absorption factor" and "external blower."
  • Specifies components considered part of grease filters such as detachable coverings and filter frames.

• Measurement conditions:

  • Installation setup using ducts matching manufacturer recommendations.
  • Electrical supply voltage conditions for testing both range hoods and external blowers.
  • Volume airflow testing with specified pressure drops at different duct diameters.

• Performance parameters tested:

  • Volumetric airflow - Measured under standardized duct pressure drops (5, 15, 30 Pa) to reflect typical operational conditions.
  • Grease absorption - Tests effectiveness of grease filters using defined pans and temperature controls; external blowers can be excluded for this test if airflow is simulated.
  • Odour extraction - Conducted with sealed kitchen cabinets, airflow meters, and auxiliary fans where applicable; also includes specific setup for island and wall-mounted hoods.

• Testing apparatus and procedures:

  • Use of auxiliary fans and absolute filters.
  • Detailed test rigs with defined dimensions for measurement consistency.
  • Pan specifications including diameter, material, and thickness for grease and odour tests.
  • Static pressure gauges and flow measurement techniques defined in figures.

• Amendment specifics:

  • Adds clarity on external blower testing conditions.
  • Updates definitions and notes for grease filter assemblies.
  • Details adjustments to airflow and extraction test conditions.
  • Standardizes temperature measurement methods with thermocouples.

Applications

• Manufacturers benefit by leveraging EN 61591:1997/A1:2006 for designing and validating compliance of range hoods and cooking fume extractors with European norms.
• Testing laboratories follow these procedures to generate accurate and comparable performance data essential for product certification.
• Regulatory bodies use this standard to enforce performance requirements ensuring consumer safety, indoor air quality, and appliance efficiency.
• Consumers gain from improved product transparency and assurance on extractor hood efficiency, grease capture capabilities, and odour removal.
• The standard is applicable in residential kitchens as well as in instances where external blowers are integrated and controlled by the range hood, critical for enhanced ventilation performance.

Related Standards

• IEC 61591:1997/A1:2005 – The international baseline standard which EN 61591 aligns with.
• IEC 60704-2-13:2000 – Specifies test codes for determining airborne acoustic noise from household electrical appliances, including range hoods.
• Additional standards under IEC TC 59 series, focusing on performance and safety of household electrical cooking appliances.
