Overview
EN ISO 8669-2:1996 - Urine collection bags: Requirements and test methods specifies performance requirements and standardized test methods for body‑worn and non‑body‑worn open‑ended and closed urine collection bags. Published as part of the ISO 8669 series and adopted by CEN, this part sets objective criteria for leakage resistance, mechanical strength, filling behaviour and nonreturn valve performance. It does not apply to urostomy bags, urimeters or urine bags intended specifically for paediatric use.
Key topics and technical requirements
- Scope and definitions - Distinguishes open‑ended vs closed bags, rated volume and test volume (see ISO 8669‑1 for vocabulary).
- Rated volume / test volume - Measured by a defined filling procedure; the rated volume must not exceed the test volume.
- Leakage tests:
- Freedom from leakage without load - 75% of test volume, horizontal then vertical inspection using coloured water (erythrosin).
- Under load - Compressive load (specified force) between parallel plates with visual inspection for leakage.
- Under impact - Drop tests from specified height with 50% test volume to check impact resistance.
- Nonreturn valve performance - Measures reflux flowrate under load; maximum allowable reflux specified (10 ml/min).
- Attachment strength - Tests for suspension cutouts, button/buttonhole systems and integral suspensory systems to verify no failure of attachment points.
- Inlet tubing attachment - Tensile test to ensure tubing does not detach.
- Filling behaviour - Pressure/time to initiate flow and minimum average filling rate (water should start within 1 minute; filling rate not less than 10 ml/s).
- General test conditions - Standard temperature (23 °C ± 2 °C), materials as supplied to end user, and specified reagents (tap water; coloured water for leakage tests).
- Dimensions - If provided by manufacturer, measured per Annex A.
Practical applications and users
This standard is essential for:
- Manufacturers of urine collection bags to design and validate products that meet regulatory and quality expectations.
- Test laboratories performing conformity testing and issuing reports against EN ISO 8669‑2:1996 criteria.
- Regulatory bodies and procurement teams assessing product safety and performance for clinical use.
- Healthcare institutions and clinicians evaluating device suitability for in‑patient or ambulatory use.
Using EN ISO 8669‑2:1996 supports consistent medical device testing, reduces device failure risk (leakage, detachment, reflux) and facilitates third‑party certification and quality assurance.
