Air Quality Sciences (AQS), an independent third-party product emissions, chemical and microbiology testing facility, received International Organization for Standardization (ISO)/International Electrotechnical Commission (IEC) 17025 accreditation for testing protocols for indoor environments and products.

ISO/IEC 17025 is an international standard that assesses the technical competency of laboratories. The standard covers every aspect of laboratory management, ranging from sample preparation to analytical testing proficiency to record keeping and reports. The standard focuses on several elements including, but not limited to, the laboratory’s quality system, document control, corrective and preventive action, accommodation and environmental conditions, equipment, measurement uncertainty, evidence of traceability, sampling, and much more.

The scope of testing activities for which AQS received accreditation includes chemical emissions from materials and products used indoors; volatile organic compounds, formaldehyde and other carbonyl compounds polluting indoor air; and chemical emissions from printers and copiers, appliances, wood products, seating, office furniture systems and the components that comprise these systems. In addition, AQS also received accreditation for testing interior coatings, materials and wood products for microbial growth.

AQS provides product-testing services for the GREENGUARD Certification Programs and the German Blue Angel Labeling programs, which provide independent third-party certification for low-emitting products used indoors.
