Tiêu chuẩn ISO8871-5

Vật liệu thử nghiệm

The NPT-01 Needle Puncture Tester evaluates puncture resistance of materials like rubber stoppers, infusion bag films, protective gloves, medical closures, and artificial skin. These materials must meet ISO 8871-5 requirements to ensure integrity and safety in medical and pharmaceutical use. The tester supports various needle types and sample holders tailored for these applications.

Quy trình kiểm tra

Following ISO 8871-5, the test mounts the chosen needle to a load cell while securing the sample on the base. The needle advances at a controlled speed until puncturing the material. The maximum force required for puncture is recorded via a precise sensor and displayed on a user-friendly screen. Test speeds and needle types can be adjusted to meet different testing demands.

Giải thích kết quả xét nghiệm

The recorded puncture force reflects material resistance. A higher force indicates better puncture resistance, important for packaging integrity and user safety. Results are compared against ISO 8871-5 standards to confirm compliance. Consistent puncture forces ensure reliable product quality and safety in practical use.
