Quality Assurance & Testing Standards

Every batch undergoes rigorous validation before release. Our facility is ISO 9001:2015 and ISO 14001:2015 certified.

Tensile & Fatigue Testing

Wire strength and bending endurance verified using universal testing machines. Ensures staples won't snap or deform under load.

ASTM A228 / ISO 6892-1

Dimensional Accuracy

Laser micrometry and optical inspection guarantee ±0.02mm tolerance on crown width, leg length, and wire diameter.

ISO 1101 / DIN 6613

Corrosion Resistance

Neutral salt spray testing (NSS) validates coating durability. Eco and standard series exceed 240h exposure without degradation.

ASTM B117 / ISO 9227

Feeding & Jam Rate Analysis

Automated cycling tests simulate 100,000+ staple feeds across 50+ stapler models. Target jam rate: <0.2%.

Internal Protocol SCP-09

Flatness & Straightness

Crown and leg alignment verified to prevent feeding friction. Torsion testing ensures consistent leg opening angles.

ISO 2768-mK

Batch Traceability

Full lot tracking from raw wire spool to final packaging. Certificates of Analysis (CoA) provided with every shipment.

ISO 9001:2015
