Volatile organic compounds ("VOCs") are chemicals that, along with oxides of nitrogen and sunlight, create ground level ozone, a major component of smog. The Federal Trade Commission (FTC) has determined that an emission-free or zero-emissions (or VOC) paint claim can be substantiated by, among other things, evidence demonstrating the

Volatile Organic Compound (VOC) Control Regulations VOCs react with nitrogen oxides on hot summer days to form ozone (smog). Car exhaust, gasoline-powered lawn and garden equipment, gasoline dispensing stations, industrial coating operations, printing shops, paints, household chemicals - are some of the sources of VOC.

The sum of VOC emissions in winter and autumn throughout China was 9.2% higher than that in spring and summer . Moreover, the abundant precipitation in summer and spring can greatly alleviate VOC pollution. However, in Shanghai and Heshan, the highest VOC concentrations were found in spring due to the location of the sampling sites and local

770-866-3200 VOC Emissions Testing and VOC Content Testing As a laboratory that provides testing services and third-party certification for manufacturers seeking designation that their products are “green”, we are often asked the difference between VOC emissions testing and VOC content testing. There is a difference.

10/16 · Broadly speaking, VOC emissions monitoring can be split into five categories: Permit compliance In addition to regulations limiting the use of solvents in products such as paints, coatings, adhesives, aerosols, cleaning chemicals and inks, there are also regulations that set emissions limits from industrial processes.

The Standard Method for the Testing and Evaluation of Volatile Organic Chemical Emissions From Indoor Sources Using Environmental Chambers, an expanded standard for what is commonly known as California Specification 01350, is one of the most widely used standards to evaluate building and interior products for low chemical emissions.

The results are only valid for the tested sample(s). This report may only be copied or reprinted in its entity, parts of it only with a written acceptance by Eurofins. 392-2020-00129401_H_EN_02 Page 5 of 10 5 Results 5.1 VOC Emission Test Results after 11 Days

The units for VOC emission limits will vary depending on the source category, the age of the source, the location of the source, and the regulating agency. Therefore, the requirements for VOC measurements, via testing, may include reporting the emissions on a mass rate. However, the VOC methods in 40 CFR 60 Appendix A,

2022/4/11 · Some VOCs react slowly or form less ozone; therefore, changes in their emissions have limited effects on local or regional ozone pollution episodes. The EPA lists compounds

2022/4/8 · The average annual VOC concentration was high in the NWC region and ranged 50.3–75.0 ppbv (with an average of 62.7 ± 17.5 ppbv) ( Fig. 2 ). As one of the major cities in the NWC region, vehicle exhaust and industrial emissions were the dominant VOC contributors in Xi’an, indicating an urgent need to control VOC pollution ( Song et al., ).
