CRI Testing Programs Green Label Plus Carpet, Adhesive and Cushion

GLP Testing Protocol And Product Requirements

GLP Carpet and AdhesiveGreen 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 outgrowth of, and enhancement to the CRI Green Label Carpet Testing Program. By selecting Green Label Plus carpet, adhesive or cushion, 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 California's Section 01350 Standard Practice for VOC Testing that measures emissions for a range of possible chemicals. 

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:

  • CRI Green Label Plus Label for CarpetAcetaldehyde
  • Benzene
  • Caprolactam
  • 2-Ethylhexanoic Acid
  • Formaldehyde
  • 1-Methyl-2-Pyrrolidinone
  • Naphthalene
  • Nonanal
  • Octanal
  • 4-Phenylcyclohexene
  • Styrene
  • Toluene
  • 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:

  • CRI Green Label Plus Label for AdhesiveAcetaldehyde
  • Benzothiazole
  • 2-Ethyl-1-Hexanol
  • Formaldehyde
  • Isooctylacrylate
  • Methylbiphenyl
  • 1-Methyl-2 Pyrrolidinone
  • Naphthalene
  • Phenol
  • 4-Phenylcyclohexene (4-PCH)
  • Styrene
  • Toluene
  • Vinyl Acetate
  • Vinyl Cyclohexene
  • Xylenes (m-,o-,p-)

Cushion Product: Cushion products are independently tested for emission levels of 11 compounds. Nine of these compounds are from the CA 01350 list (those that have actually occurred in cushion) and two remain from the Green Label Program. Thus, a Green Label Plus certified cushion is also compliant with the Green Label criteria. The 11 compounds measured are:

  • Formaldehyde
  • Phenol
  • Acetaldehyde
  • 1,4 Dichlorobenzene
  • Styrene
  • Toluene
  • Xylene
  • Isophorone
  • Naphthalene
  • BHT
  • 4 Phenylcyclohexene

In order to earn and maintain Green Label Plus certifications, carpet, adhesives and cushion products must undergo a three-tier testing process to monitor continued compliance with the test program requirements.

Carpet

  • Initial Test – The carpet is tested to ensure it meets all the compound emissions standards as outlined by California DHS Section 01350.
  • Interim Testing – 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 ensure it meets very stringent emission criteria for thirteen individual compounds as well as testing for TVOCs.

Adhesive

  • Initial Test – The adhesive is tested to ensure 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 percent of all product categories are randomly selected to be tested with the same stringent testing protocol as the annual testing requirements.

Cushion

  • Initial Test- The cushion is tested to ensure it meets all of the compound emissions standards as outlined in California DPH Section 01350.
  • Annual Test- The cushion is tested in accordance with the established emission testing criteria for 11 individual compounds.
