Racine Industries Questions Validity of SOA Program

摘要

Racine Industries has released a peer-reviewed white paper that examines the methods of using x-ray spectrometry (XRF) for testing carpet cleaning extractors, systems and vacuums. The Carpet & Rug Institute (CRI) uses these methods to establish rankings for the Seal of Approval (SOA) Program. The study reported findings that suggest that it is premature to conclude that the testing accomplishes the stated objective of quantifying soil levels in carpet and suggests that further research be conducted prior to widespread acceptance of the SOA Program.
