Delamination of Secondary Backing
ASTM D3936 – Delamination Strength of Secondary Backing (Carpet)
Floor Detective® Claims and Conditions Guide
What You Need to Know
• Delamination refers to the separation of a carpet’s secondary backing from the primary backing
• ASTM D3936 provides a laboratory procedure for measuring the force required to cause this separation
• The test evaluates the adhesive bond strength between the primary and secondary backing systems
• Results are used to assess a carpet’s resistance to stresses that may occur during
