Testing protocol and product requirements
CRI has established the Green Label program to test for VOCs in cushion used under carpet. This program helps the carpet manufacturer, installer and end user identify and utilize low-emission cushion.
Cushion products that meet the current emissions criteria can display the program’s green and white seal. Products are retested regularly for continued compliance, so specifiers seeking a low-emitting cushion can confidently select one bearing the Green Label.
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).
Criteria are base on a maximum emission factor as follows:
