ISO 29463 HEPA Filter Classification and Testing: Eurolabs Laboratory Testing Service
ISO 29463 is a widely accepted international standard for the classification and testing of High Efficiency Particulate Air (HEPA) filters. The standard provides a framework for evaluating the performance of HEPA filters in removing particles from the air, ensuring that they meet specific requirements for various industries.
Legal and Regulatory Framework
The use of HEPA filters is governed by international and national regulations, which require manufacturers to test their products against established standards. In Europe, the European Unions Machinery Directive (2006/42/EC) and Low Voltage Directive (2014/35/EU) mandate that manufacturers comply with relevant standards for safety and performance.
International and National Standards
Several standards govern the testing of HEPA filters:
