Inquiry

We are using a European wool carpet, Broadloom Carpet Rollerwool by Ruckstuhl USA. This carpet that has no CRI Green Label Plus certificate since it is mostly used on the European market. To prove that this wool carpet meets or exceeds the minimum requirements for a CRI plus certification the manufacturer had AQS (Air Quality Science, Inc.) conduct an \'Industry Criteria Test For Carpet Green Label Plus Acceptance\'. We would like to inquire if it is possible to achieve EQc4.3 through the use of the carpet specified for the project even though the product does not have CRI Green Label Plus certificate. AQS tested and reported according to the "Method for the Evaluation of Chemical Emissions from Flooring Using Environmental Chambers", and prepared the report (AQS Report#: 16127-01) on October 15, 2008. They tested the carpet for emission levels for seven chemicals as required by Section 01350, plus six additional chemicals as required by CRI (Acetaldehyde, Benzene, Caprolactam, 2-Ethylhexanoic Acid, Formaldehyde, 1-Methyl-2-Pyrrolidinone, Naphthalene, Nonanal, Octanal, 4-Phenylcyclohexene, Styrene, Toluene, Vinyl Acetate). All 13 chemicals were measured and their Emission Factors and Air Concentrations were far below the CRI criteria if at all quantifiable. The submitted reports can be provided as per your request. They include the following: 1. Target Chemicals, emission results at 14 Days. 2. Target Chemicals, emission results at 24 hours. 3. Summery of TVOC and Formaldehyde Chamber Concentrations, Emission Factors and Predicted Air Concentration. 4. Ten Most Abundant Identified Individual VOCs and /or Aldehydes (at 336 hours). 5. Comparison of Data to CHPS Section 01350 Requirements (at 336 hours). 6. VOC Predicted Air Concentrations and Regulatory Information.
