Overview

prEN 14079-2 (CEN) - "Non-active medical devices - Properties for compresses and wound packing products for medical use - Part 2" defines test methods for evaluating absorbent cotton gauze and absorbent cotton & viscose gauze used as compresses and wound packing products. This draft European standard focuses on physical and chemical test procedures (conditioning, absorbent capacity, absorption rate, construction strength, x‑ray opacity, dimensions) to support product evaluation, quality control and regulatory conformity in the EU market. Note: biocompatibility and bioburden are addressed in separate standards (EN ISO 10993 and EN XXX respectively).

Key Topics and Requirements

• Scope: Test methods for compresses and wound packing products made from absorbent cotton gauze and cotton/viscose blends; intended to be used in conjunction with prEN 14079-1 for material-specific requirements.
• Conditioning (Annex A): Standard atmospheric conditions for testing - 20 °C ± 2 °C and 65 % ± 10 % relative humidity; procedure for stabilising sample mass before testing.
• Absorbent capacity (Annex B): Water retention test using a perforated stainless steel tray (perforations 3 mm diameter, 5 mm centre spacing), controlled immersion/drain procedure and a defined metal weight to express retention as grams liquid per gram product. Test report must include batch identification, individual results, mean value, deviations and tester identity.
• Absorption rate (Annex C): Time-to-sink / time-to-wet test in deionised water at 20 °C ± 2 °C, measured with stopwatch; repeat measurements and mean reporting.
• Construction strength (Annex D): Methods to assess the mechanical reliability and integrity of the compress/wound packing construction (see standard for specified test set-up).
• X-ray opacity (Annex E) and Dimensions & plies (Annex F): Tests to verify the presence and attachment of x‑ray detectable components and dimensional conformity including number of plies.
• Test reporting: Clear requirements for documenting product type/batch, measured values, deviations and responsible personnel.

Applications and Who Uses It

• Medical device manufacturers: product design verification, supplier control and production quality assurance for gauze compresses and wound packing products.
• Testing and certification laboratories: standardized test procedures for conformity assessment and routine batch testing.
• Regulatory and compliance teams: evidence for CE-marking and to demonstrate alignment with EU directives (see informative Annex ZA).
• Procurement and clinical engineers: specification writing and acceptance testing of sterile or non‑sterile gauze products.

Related Standards

• prEN 14079-1 - material‑specific tests and requirements for absorbent gauzes (use in conjunction).
• EN ISO 10993 - biological evaluation (biocompatibility).
• EN‑ISO 13934-1, ISO 565, EN ISO 3696 - referenced test methods and laboratory practices.

Keywords: prEN 14079-2, absorbent cotton gauze, wound packing products, test methods, absorbent capacity, construction strength, x‑ray opacity, CEN, non-active medical devices.
