In 1992, CRI launched its Green Label program to test carpet, cushions and adhesives to help specifiers identify products with very low emissions of VOCs. CRI also launched the next series of improvements called Green Label Plus for carpet and adhesives; the enhanced program, that uses scientifically established standards, sets an even higher standard for IAQ and ensures that customers are purchasing the very lowest emitting products on the market.
CRI designed the Green Label and Green Label Plus programs for architects, builders, specifiers and facility mangers who want assurances that carpet and adhesive products meet the most stringent criteria for low chemical emissions.
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.
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.
Cushion products are characterized as prime polyurethane, bonded polyurethane, mechanically frothed polyurethane, rubber-hair, rubber–jute, synthetic fiber, resinated or coated synthetic fiber, rubber and rubberized polyurethane. Cushions are tested for total volatile organic compounds (TVOCs), butylated hydroxytoluene (BHT), formaldehyde and 4-phenylcyclohexine (4-PCH).
