Introduction Reliable VOC emission testing requires more than stable temperature, humidity, and airflow. The cleanliness of the environmental chamber and its associated air-supply and sampling systems can also influence the quality of test results. R...

Introduction Manufacturers of construction products may encounter ISO 16000-9 and EN 16516 when evaluating emissions into indoor air. Both involve chamber-based testing, but they have different scopes and roles. Understanding the distinction is impor...

Introduction In VOC emission testing , two terms are often used together: chamber air concentration and emission rate. Although they are related, they describe different properties. Chamber air concentration indicates how much of a target compound i...

Introduction VOC emission testing plays an important role in evaluating building materials, furniture, and other indoor products. In the United States, the California Department of Public Health (CDPH) Standard Method is one reference used by program...

Introduction Repeatability is an important consideration in VOC emission testing. When the same material is tested more than once, laboratories need to understand whether differences in results reflect actual changes in the material or variation in t...

Introduction Volatile organic compound (VOC) emission testing is widely used to evaluate emissions from building materials, furniture, coatings, adhesives, and other products. Environmental chamber allows laboratories to measure emissions under contr...
