Carpet And Adhesive
Testing protocol and product requirements
Green Label Plus is an independent testing program that identifies carpet with very low emissions of VOCs to help improve indoor air quality. It is an enhancement to the CRI Green Label Carpet Testing Program. By selecting Green Label Plus carpet or adhesive, you are assured one of the lowest emitting products on the market, and you may be able to earn LEED, Green Globes, or Green Guide for Health Care points.
To receive initial certification, carpet products undergo a 14-day testing process, as required by Section 01350 that measures emissions for a range of possible chemicals. CDPH Section 01350 Standard Practice for VOC Testing
Carpet products: An independent laboratory tests carpet products for emission levels for seven chemicals as required by Section 01350, plus six additional chemicals as required by CRI. The 13 chemicals measured are as follows:
- 2-Ethylhexanoic Acid
- Vinyl Acetate

Adhesive products: Adhesive products are also independently tested for emission levels for 10 chemicals as required by Section 01350, plus 5 additional chemicals. The 15 chemicals measured are as follows:
- 1-Methyl-2 Pyrrolidinone
- 4-Phenylcyclohexene (4-PCH)
- Vinyl Acetate
- Vinyl Cyclohexene
- Xylenes (m-,o-,p-)

In order to earn and maintain Green Label Plus certifications, carpet and adhesives must undergo a three-tier testing process to monitor continued compliance with the test program requirements.
- Initial Test – The carpet is tested to insure it meets all the compound emissions standards as outline by California DHS Section 01350.
- Quarterly Test – As a quality control measure the carpet is tested in accordance with established emissions testing criteria for the total level of volatile organic compounds (TVOCs).
- Annual Test – The carpet is tested in accordance with established emission testing criteria to insure it meets very stringent emission criteria for thirteen individual compounds as well as testing for TVOCs.
- Initial Test – The adhesive is tested to insure it meets all the compound emissions standards as outlined by California DHS Section 01350 and meets stringent total volatile organic compounds (TVOC) requirements.
- Annual Test – The adhesive is tested in accordance with established emissions testing criteria for 15 individual compounds and stringent total volatile organic compounds (TVOC ) requirements
If the adhesive fails the 24 hour emissions criteria, then a 14 day emission test is conducted in accordance with California DHS Section 01350 criteria to determine if it meets the emissions standard.
- Semi-Annual Test – 25% of all product categories are randomly selected to be tested with the same stringent testing protocol as the annual testing requirements.
