VOC Overview
VOC is the abbreviation of volatile organic compounds. According to
the WHO definition, volatile organic compounds (VOC) refer to
various organic compounds with a boiling point of 50℃-260℃ under
normal pressure.
VOC can be further divided into alkanes, aromatic hydrocarbons, esters, aldehydes and others according to their chemical structure. More than 300 types have been identified so far. The more common ones are benzene, toluene, xylene, styrene, trichloroethylene, trichloromethane, trichloroethane, diisocyanate (TDI), diisocyanatotoluene, etc.
VOC sources:
1. Incomplete combustion: fuel combustion, garbage incineration,
vehicles, etc.;
2. Process emissions: oil refining, petrochemicals, organic fine
chemicals (paints, inks, adhesives, pesticides, medicines), etc.;
3. Oil volatilization: oil refining, petrochemicals, oil storage
depots, gas stations, vehicles, etc.;
4. Solvent use: plastic and rubber product processing, industrial
coating (cleaning), building coating, printing and packaging, wood
and furniture manufacturing, shoemaking, leather, semiconductor and
electronic product manufacturing, dry cleaning, automobile
maintenance, etc.;
5. Biological action: sewage treatment plants, landfills, natural
sources, etc.
VOC testing services
1. New national standard VOC testing for paints, inks, adhesives,
and cleaning agents
In order to assist enterprises in the management and control of
related materials and help them win the "blue sky defense war", SGS
established comprehensive VOCs testing capabilities as soon as
possible. At present, SGS has obtained the China Metrology
Certification (CMA) qualification for coatings, adhesives, inks,
cleaning agents and related supporting testing standards, which
effectively helps enterprises to do a good job in source management
and ensure that products meet the requirements of the national
mandatory standards for VOCs.
2. VOC testing of home decoration materials
There are many types of decoration and decorative products, but the
quality varies. The home decoration product testing services
provided by SGS and comprehensive certification standards can help
retailers, suppliers and manufacturers determine whether the
products meet regulatory requirements, avoid economic losses caused
by product accidents or recalls, and help your products win the
market smoothly.
The main tested products include: candle aromatherapy, paint,
material, adhesive; floor, carpet, wallpaper, ceiling; windows and
doors; mattress; furniture, office furniture, children's furniture,
etc.
3. Automobile VOC testing
The air quality in the car has now been listed as an industry
hotspot and industry problem that major automobile OEM
manufacturers around the world focus on. SGS has the approval
qualifications of many OEMs, mainly through comprehensive VOC
testing at the vehicle level, component level, and material level,
so that the products meet international, national, and corporate
standards and create a green and safe riding environment.
The main test items include: whole vehicle, cabin method, bag
method, odor, atomization, formaldehyde, total carbon, VDA278, etc.
IV. VOC detection of stationery and cultural and educational
products
The main test products include: teaching tools, books, exercise
books, pigments, calligraphy and painting ink, ballpoint pens, gel
pens, crayons, watercolor pens, chalks, highlighters, correction
fluid, glue, paper clips, erasers, pen bags, key pendants.
New national standard for VOC
On July 3, 2018, the State Council issued the "Three-Year Action
Plan for Winning the Blue Sky Defense War", which clarified the
overall ideas, basic goals, main tasks and guarantee measures for
air pollution prevention and control, and proposed a timetable and
roadmap for winning the blue sky defense war. The plan regulates
the VOC test methods and content limits for four VOC high-risk
materials: coatings, inks, adhesives, and cleaning agents. In
2019-2020, the National Standardization Administration has
formulated and announced 10 mandatory national standards for
limiting the VOCs content of coatings, inks, adhesives, cleaning
agents and other products. The list of standards and implementation
dates are as follows:
Standard No.

GB 38597-2020
Technical requirements for coating products with low volatile organic compound content
2021-02-01
In recent years, various regions have issued local or regional laws, regulations and rules and regulations in accordance with the "Law on the Prevention and Control of Air Pollution" and "Winning the Battle to Protect Blue Skies", encouraging the use of coatings, inks, adhesives and cleaning products with low volatile organic content. Traditional high-risk and high-pollution products must be upgraded and transformed to meet the requirements of green production.
The implementation of this series of standards will have a significant impact on the production and application companies of coatings, inks, adhesives and cleaning agents. At present, in response to the Blue Sky Defense Action Plan, end-user companies at all levels are investigating products such as coatings, inks, adhesives, and cleaning agents involved in the supply chain. With the implementation of the new national standard imminent, SGS can help companies implement effective product and raw material testing measures, strictly control product quality, and avoid environmental violations.
