Emeryville, Calif.—SCS Global Services and SCS Standards and Assurance Systems have released Version 2.1 of the SCS-111 Certification Standard for Rigid Core Resilient Flooring.
The organizations also updated the Assure Certified program, which uses the standard.
Version 2.1 incorporates the ASTM F3781 test method. The method requires certified rigid core flooring to meet a defined edge-strength threshold.
The update provides an independently validated measure of how flooring locking technologies perform under real-world stress. SCS said the requirement adds another performance measure to the certification program.
Rigid core flooring remains one of the fastest-growing segments of the flooring market. The Assure Certified program aims to build trust among consumers, retailers and builders regarding product performance and safety.
ASTM F3781, Standard Test Method for Measurement of the Fracture Resistance of a Modular Resilient Flooring’s Profiled Edge(s) to an Applied Vertical Force, adds another testing requirement to SCS-111 Version 2.1.
Certified products must achieve a minimum of 17 pounds-force in vertical edge-strength testing. The requirement provides an independently validated and reproducible measure of edge strength.
“By incorporating the ASTM F3781 edge-strength requirement, we’re giving manufacturers a clear, science-based way to focus on a key component of edge durability,” said Victoria Norman, executive director of SCS Standards and Assurance Systems. “This new component of Assure Certified joins key testing for ortho-phthalates, heavy metals content, indoor air quality and other performance factors. This update strengthens the Assure Certified program and helps raise the bar for the entire industry.”
ASTM test method development
The Resilient Floor Covering Institute coordinated development of the ASTM test method through a multiyear, multi-stakeholder collaboration.
Three interlaboratory studies supported the development process. The work included a blind-coded evaluation of numerous products representing a range of locking technologies.
The resulting test method reflects scientific consensus and industry participation.
“Assure Certified has always been based on rigorous testing, verified performance and on-site inspection of manufacturing facilities,” said Rob Emelander, operations director for flooring at SCS Global Services. “Incorporating ASTM F3781 gives certified products another layer of proof—one that directly reflects the stresses floors undergo in homes and businesses. It’s a meaningful step forward for product transparency.”
Organizations seeking Assure Certified certification will undergo audits using Version 2.1.
Existing certificate holders seeking recertification must transition to the new version during their next annual audit. SCS requires all certificate holders to complete an audit under Version 2.1 by May 31, 2027.
The revised SCS-111 standard is available through the SCS Standards website. Information about SCS-111 certification services is available through the SCS Global Services website.
