ASTM D3936 – Delamination Strength of Secondary Backing (Carpet)

Floor Detective® Laboratory Testing Reference

Summary

ASTM D3936 Delamination Strength testing measures the force required to separate a carpet’s secondary backing from its primary backing under controlled laboratory conditions. The test evaluates the adhesive bond strength between backing components and is commonly used during investigations involving backing separation, delamination, durability concerns, manufacturing quality control, and specification verification. Results provide comparative information regarding backing adhesion and should be interpreted together with carpet construction, manufacturing history, field observations, and other laboratory findings. Laboratory results do not independently establish manufacturing defect, warranty responsibility, product failure, or field causation.
