Overview
ISO 29464:2024 - Cleaning of air and other gases - Vocabulary is an international standard developed by the International Organization for Standardization (ISO). This standard provides clear and uniform definitions for key terms used across the air filtration industry. By standardizing terminology, ISO 29464:2024 supports improved communication, manufacturing consistency, and regulatory compliance in applications involving air and gas cleaning.
The vocabulary covers particulate matter and gas-phase air filters and air cleaners for general ventilation of inhabited enclosed spaces. It also includes terminology for air inlet filters on static or seaborne rotary machinery, cleanable filters, UV-C germicidal devices, and stand-alone electrically-powered air cleaners. The standard specifically excludes cabin filters for road vehicles, mobile internal combustion engine air filters, and dust separators for pollution control.
Key Topics
ISO 29464:2024 structures terminology under several important themes relevant to air cleaning technology:
- Particle and Gas-Phase Air Cleaners: Definitions relating to the function, operation, and classification of air cleaners and air filters designed to remove contaminants from air or gases.
- Particulate Matter Filters: Terms applicable to various filter types, including general ventilation, EPA, HEPA, and ULPA filters, along with measures of efficiency and performance.
- Rotary Machine Air Intake Filters: Specialized vocabulary for air inlet filters used on static and seaborne rotary equipment.
- Cleanable Filter Degradation: Concepts addressing the lifespan and cleaning cycles of reusable filter technologies.
- Gas Phase Air Cleaners (GPAC): Nomenclature for filters and devices targeting the removal of gaseous contaminants.
- UV-C Germicidal Devices: Terms concerning equipment that uses ultraviolet light for microbial control in air handling systems.
- Stand-Alone Electrically-Powered Air Cleaners: New terminology added in the 2024 edition for portable or autonomous air purification devices.
The standard also includes explanations for critical performance parameters such as removal efficiency, bypass, penetration, filter media, and maintenance procedures like cleaning and clogging.
Applications
ISO 29464:2024 is relevant to numerous sectors and practical applications, including:
- HVAC and General Ventilation: Ensuring uniform terminology in specifications and maintenance of ventilation systems for offices, hospitals, schools, and public buildings.
- Industrial Air Filtration: Supporting clear definitions for equipment in manufacturing environments, clean rooms, and critical processing facilities.
- Static and Seaborne Machinery: Promoting consistent language for air inlet filters on turbines, generators, and marine equipment.
- Facility Hygiene and Indoor Air Quality: Guiding the use and performance assessment of germicidal UV-C devices and standalone air cleaners within inhabited spaces.
- Product Development and Specification: Assisting manufacturers in product documentation, marketing materials, compliance statements, and technical instructions through standardized terms.
By adopting ISO 29464:2024, organizations can improve the accuracy of communications, product labeling, and compliance with regulatory or customer requirements concerning air filtration and purification.
