Tensile Protocol
Standardized mechanical testing procedures evaluate the breaking force and elongation properties of individual yarn strands under constant rate of extension conditions. Conducted according to international standard specifications, single strand tensile test ISO 2062 provides authoritative tensile strength data for flax and linen spun yarns. The method measures peak breaking force in newtons and percentage elongation at rupture using pneumatic yarn clamps.
Spinning mills rely on these standardized parameters to verify yarn performance during high-speed weaving operations.
Laboratory Method
Specimen conditioning precedes testing to ensure yarn moisture reaches equilibrium in a standard atmosphere. The single strand tensile test ISO 2062 procedure mounts fifty individual yarn strands per sample lot into an automated tensile testing machine. Pneumatic grips prevent specimen slippage and jaw breaks during loading.
Computerized testing software calculates mean breaking force, tenacity in centinewtons per tex, and coefficient of variation across test series.
Quality Compliance
Loom performance correlates directly with single strand tenacity and elongation values recorded during testing. Quality certificates displaying single strand tensile test ISO 2062 metrics accompany exported yarn shipments to prove compliance with buyer technical requirements. Non-conforming test results trigger raw material re-blending or twist adjustment on spinning frames.
Mill laboratories retain digital test records for legal verification.
