Methods & Standards

UL AQS plays a key role in developing global emissions testing standards for a variety of products. We help manufacturers understand the best test method to meet their market demands. Take a look at our website to gain a better understanding of some of the leading test methods. If you don’t see the method you are looking for, please contact us for more information.

California Section 01350 Test for VOC Emissions

The State of California is a leader in environmental initiatives. Indoor air is no exception. One of the most common emissions test methods in North America is California's Section 01350 test protocol or California Department of Public Health CDPH/EHLB/Standard Method V 1.1 Standard Method for the Testing and Evaluation of Volatile Organic Chemical Emissions from Indoor Sources Using Environmental Chambers.

Carpet Cushion Certification Program

The Carpet Cushion Council (CCC) and Carpet and Rug Institute (CRI) certify carpet/flooring cushion for low chemical emissions through the Green Label certification program. UL AQS helped the industry develop test methods and acceptance criteria for the program. It has served as the emissions testing partner for the carpet cushion industry for over 20 years.

Clean Room Classification

A clean room environment used in high tech and biotechnology manufacturing, operations or scientific research requires a low level of airborne environmental pollutants, such as dust and chemicals. UL AQS uses specialized chambers and particle monitoring equipment to help product manufacturers demonstrate their products' acceptability for use in clean room environments. Products frequently tested include furniture, flooring, and ceiling systems. UL AQS...

Electronics and Printers

Commercial and consumer electronics and printers can be sources of chemical, particle, ozone, and other gas emissions to the indoor environment. This is largely due to the multiple components and materials with which they are built, as well as the heat they generate during operation. The European Computer Manufacturers Association Test Method 328 (ECMA 328), Blue Angel RAL-UZ-171, ISO/IEC 28360 test method, and GREENGUARD test methods GGTM.P058 and...

Furniture Emissions Testing

The office furniture industry faces unique product emissions issues due to the materials commonly used to make furniture and the variety of options typically offered by each manufacturer. To help manufacturers address emissions issues, the Business and Institutional Furniture Manufacturers Association (BIFMA) created a test method (ANSI/BIFMA M7.1) and standard (ANSI/BIFMA X7.1) for chemical emissions from office products and components. AQS has...

Green Label Plus Program

The Carpet and Rug Institute (CRI) certifies carpets and adhesives for low chemical emissions through the Green Label Plus (GLP) program. This program assesses products for a series of VOCs, including California chronic reference exposure levels (CRELS) and other potential odorants and irritants. UL AQS has served as the emissions testing partner for the carpet industry for over 20 years and maintains extensive knowledge of carpet and adhesives...


As the primary scientific partner for the GREENGUARD Certification Program, UL AQS is fully qualified and experienced in developing certification plans and performing emissions testing and data review. The GREENGUARD Environmental Institute develops and maintains product emission test methods and emissions criteria for numerous product types including building and interior products, furniture, printers, electronic products, and cleaning products. For...

International Test Methods

The European and Asian markets are increasingly requiring low-emitting products and introducing regulations on product emissions. UL AQS closely follows these developments so that we can help product manufacturers ensure compliance with all global requirements. We are the only emissions testing laboratory in North America that is approved by the Federal Institute for Materials Research and Testing (BAM) for measuring emissions of both electronics and...

Exposure Risk

An indoor air quality (IAQ) risk assessment evaluates a product's potential to produce adverse human health effects and sensory perception effects, such as irritation and odor. Emissions data obtained from an environmental chamber evaluation are used to predict indoor concentration levels of volatile organic compounds (VOCs), aldehydes, particles, ozone, and other potential pollutants. UL AQS has the expertise required to conduct a complete IAQ risk assessment for your product against a wide ar

Comprehensive Evaluations

UL AQS is the world leader in conducting IAQ risk assessment services, ensuring that all relevant pollutants are measured. UL AQS has extensive and up-to-date databases of regulatory and toxicology-based exposure guidelines.

Regulatory Compliance Testing

Emissions testing and product exposure assessments are increasingly required for regulatory compliance in certain product types. Determine the applicability of California Proposition 65 labeling requirements for your consumer product. Find out if your product results in human exposure above an occupational exposure threshold set by OSHA or state authority. UL AQS has the expertise to design an efficient test plan to meet your objectives.

Odor Assessment Service

Offensive odors from products can make customers think a product is unpleasant or unhealthy. To maintain product excellence and earn market acceptability, product manufacturers need assurance that products do not release objectionable, irritating, or potentially hazardous odors. Identifying the source of the odor is the first step towards remediating the problem.

Ultrafine Particle Studies Service

UL AQS is the premier commercial laboratory in North America to offer product testing services for the measurement of ultrafine particle (UFP) emissions. UFPs are a new class of contaminant. These particles (down to 5 nanometers in size) are of health concern because they can be inhaled deeply into the respiratory system and can even pass through protective clothing and skin. Known sources include cooking appliances, printers, and combustion...
