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, adhesives, and cushion with very low emissions of VOCs to help improve indoor air quality. It is an outgrowth of, and enhancement to the CRI Green Label 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 credit under LEED, Green Globes, or Green Guide for Health Care.
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. An independent laboratory tests products for emission levels:

* Note:
All criteria presented above are for CRI GLP 14-day and 24-hour tests except Caprolactam criteria is set at an EF of 131 μg/m2·hr and a Concentration of 70 μg/m3 for the 24-hour test.

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.

CRI Green Label Plus Cushion Program Test Criteria: Green Label Plus™ Emissions Criteria, Page 2 Emissions Criteria for Cushion PDF(PDF 120 KB)

Initial

Initial testing is required for entry to the program. Samples will be evaluated against the full listing of California Section 01350 compounds for emissions no higher than one-half the listed Chronic Reference Exposure Level (CREL) for each compound (except Formaldehyde, which is reported at the full CREL.) Refer to the GLP Emissions Criteria for a list of additional testing criteria specific to the Green Label Plus program. Additionally, the TVOC level will be reported on the GLP Certificate. Testing will be evaluated after 10 days of conditioning and 24, 48, and 96 hours (14 days) after initiating the chamber test.

Interim Annual

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 participant. An extension shall measure the full listing of California Section 01350 compounds for emissions no higher than half the listed Chronic Reference Exposure Level (CREL) for each compound (except Formaldehyde, which is reported at the full CREL.) Refer to the GLP Emissions Criteria for a list of additional testing criteria specific to the Green Label Plus program. Additionally, the TVOC level will be reported on the GLP Certificate. Testing will be evaluated after 10 days of conditioning and 24, 48, and 96 hours (14 days) after initiating the chamber test.

Biennial

Biennial testing is required for continued compliance within the GLP program. Samples will be evaluated against the full listing of California Section 01350 compounds for emissions no higher than one-half the listed Chronic Reference Exposure Level (CREL) for each compound (except Formaldehyde, which is reported at the full CREL.) Refer to the GLP Emissions Criteria for a list of additional testing criteria specific to the Green Label Plus program. Additionally, the TVOC level will be reported on the GLP Certificate. Testing will be evaluated after 10 days of conditioning and 24, 48, and 96 hours (14 days) after initiating the chamber test.
