How VOCs are measured?
The two most commonly used methods for VOC statistical analysis are Flame Ionisation Detection and Photo Ionisation Detection. Both methods measure the number of chemicals in the air on the assumption that most organic vapors produce positively charged carbon ions when they combust(1).
Are VOCs regulated?
The U.S. EPA regulates VOCs at Federal level in 40 CFR 59, which is the National Volatile Organic Compound Emission Standards For Consumer And Commercial Products. VOC controls for products are typically based on the application of products, such as: Aerosol Coatings. Architectural Coatings.

What are VOC limits?
This is defined as the “lowest level of emissions that can be achieved taking into account technical and economic considerations.” What this means for our customers is that, depending on the state in which their project is being undertaken, VOC limits may dictate the sort of product that’s called for in the project’s …

What is VOC content limits?
The federal government caps the VOC content in paint at 250 grams per liter (g/l) for flat finishes and 380 g/l for other finishes (low-luster, semigloss, etc.).
What does Summa canister stand for?
A Summa canister is a stainless steel container that has had the internal surfaces specially passivated using a “Summa” process. This process combines an electropolishing step with a chemical deactivation step to produce a surface that is nearly chemically inert.
Why is it called an ar15?
The letters stand for ArmaLite Rifle — and not for “assault rifle” or “automatic rifle.” ArmaLite first developed the AR-15 in the late 1950s as a military rifle, but had limited success in selling it. In 1959 the company sold the design to Colt.
What is the threshold for low VOC?
In general, the term “low VOC” describes a solvent whose VOC content is at or below 150 g/L. A solvent that has low VOC content usually isn’t as safe as one that has no VOCs.
