DIN 11864

DIN 11864 is a German standard that outlines the requirements for the product certification of ventilation units used in buildings. It focuses on ensuring the quality, safety, and performance of these units, ultimately contributing to improved indoor air quality and energy efficiency in buildings.

• Scope: Applies to air handling units (AHUs), central air handling units (CAHUs), and heat recovery ventilation units (HRVs) used in residential and non-residential buildings.
• Testing and certification: Products are tested by independent laboratories accredited according to EN ISO/IEC 17025. The tests cover various aspects, including:
  • Airflow rate: Measuring the volume of air the unit can move per unit time.
  • Pressure characteristics: Evaluating the unit’s ability to overcome pressure drops in the ductwork.
  • Thermal performance: Assessing the heating and/or cooling capacity of the unit.
  • Acoustic performance: Measuring the noise generated by the unit.
  • Electrical safety: Ensuring compliance with relevant electrical safety regulations.
  • Construction and materials: Verifying the use of suitable materials and construction methods.
• Certification levels: Three certification levels are available:
  • Level 1: Basic performance and safety requirements.
  • Level 2: Additional requirements for specific applications, such as increased efficiency or noise reduction.
  • Level 3: Highest level, including extended testing and requirements for advanced features.
• Benefits: Obtaining DIN 11864 certification offers several benefits for manufacturers and users:
  • Increased product credibility: Demonstrates adherence to recognized quality and performance standards.
  • Improved market access: Certification can be a requirement for certain projects or markets.
  • Enhanced user confidence: Provides assurance of product quality and safety.
  • Potential for energy savings: Certification often involves efficiency requirements, leading to reduced energy consumption.

Additional notes:

• DIN 11864 is a voluntary standard, but it is widely recognized and respected in the German and European ventilation industry.
• The standard is regularly updated to reflect technological advancements and changing market needs.
• Manufacturers can find detailed information and test procedures in the official DIN 11864 document.
