Medical Lab Testing: Breaking Strength
Breaking Strength testing measures the maximum force a material or seam can withstand before failure under tension. The test pulls a specimen at a constant rate until rupture and records the peak load and elongation. For medical manufacturers, high breaking strength is essential for surgical gowns, drapes, scrubs, and medical textiles to ensure they do not tear during procedures, laundering, or handling while maintaining barrier integrity.
Textiles and components in medical apparel must endure significant mechanical stress without failing. Weak breaking strength can lead to tears that compromise sterility or protection. Applus+ Reliable Analysis already maintains accredited tensile and breaking strength testing capabilities, integrated with our seam fatigue, abrasion, and barrier performance methods.
These evaluations support key standards for protective apparel and medical textiles. Manufacturers use breaking strength data to qualify fabrics that balance strength, flexibility, and durability for clinical use. Applus+ Reliable Analysis delivers consistent, reproducible results using equipment already operating daily under our ISO/IEC 17025 accreditation.
Common Breaking Strength Medical Testing Standards
ASTM D5034 Breaking Strength and Elongation of Textile Fabrics (Grab Test)
ASTM D5034 determines the breaking strength and elongation of textile fabrics using the grab test method. A specimen is clamped in a tensile testing machine with a defined grip separation and pulled at a constant rate until rupture. The test reports the maximum force and elongation at break. It is widely used for surgical gowns, drapes, scrubs, and medical textiles to ensure fabrics can withstand tension without tearing during clinical use and handling.
ASTM D5035 Breaking Strength and Elongation of Textile Fabrics (Strip Method)
ASTM D5035 measures the breaking strength and elongation of textile fabrics using the strip method, where a full-width strip specimen is pulled at a constant rate until failure. The standard provides data on maximum force and elongation. It is particularly relevant for medical barrier fabrics and gowns to evaluate tensile performance under uniform loading conditions encountered during use.
ISO 13934-1 Textiles Determination of Maximum Force and Elongation
ISO 13934-1 determines the maximum force and elongation at maximum force of textile fabrics using the strip method. The standard specifies specimen preparation, test speed, and reporting of results. It is essential for medical textiles intended for European markets to verify breaking strength and ensure materials can endure the mechanical stresses of clinical procedures and laundering.
AAMI PB70 / ASTM F2407 Breaking Strength for Surgical Gowns
AAMI PB70, supported by ASTM F2407, includes breaking strength as part of the overall performance requirements for surgical gowns and drapes. The standards evaluate the force required to break the fabric or seams under tension. This helps ensure gowns and drapes maintain structural integrity and barrier properties under the mechanical stresses of surgical procedures.
