GLP Passes Rigorous Testing
To receive Green Label Plus certification, carpet, adhesive and cushion products must undergo a rigorous testing
process. Emissions are measured for a range of chemicals and testing is administered by an independent laboratory.
All testing evaluates carpet against the 35 compounds listed on the California 01350 version 1.1, except for Capro-
lactam. Each product category also includes additional compounds for certification, six for carpet, two for carpet, and
seven for adhesive.
For acceptance into the GLP program, a product must pass a 14-day test of full list of 35 compounds, along with its
specific category compounds, and total level of volatile organic compound (TVOC).
Annual testing is required for continued compliance within the GLP program. Samples will be evaluated at 24 hours.
If the sample does not meet the 24-hour criteria, the test may be extended to 14 days upon approval by the partici-
pant.
Biennial testing is also required for continued certification under Green Label Plus. Done every second year after the
initial test, a test sample is evaluated at 14 days for the full list of compounds and category specific compounds.
Green Label Plus Measures Up
The Green Label Plus is an example of the Carpet and Rug Institute’s leadership in the best practices of environ-
mental responsibility. American National Standard Institute (ANSI), the premier source for international standardiza-
tion and conformity assessment, has accredited CRI for testing indoor air quality.
Green Label Plus is the first, and only, ANSI-accredited green carpet program in the U.S. An accreditation body is an
impartial third party that tests and evaluates a product to determine its compliance with relevant standards.
Green Label Plus programs, which test for and certify low emissions from carpet and adhesive, comply with the
International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC) Guide
65, General Requirements for Bodies Operating Product Certification Programs.
• ANSI Accreditation is a further assurance that the products tested and certified by CRI are green building products
that meet high standards for indoor air quality.
