Overview
ISO 8669-2:1996 - "Urine collection bags - Part 2: Requirements and test methods" specifies performance requirements and laboratory test methods for open-ended and closed urine collection bags, both body-worn and non-body-worn. It excludes urostomy bags, urimeters and bags intended specifically for paediatric use. This second edition consolidates and replaces earlier parts of ISO 8669 and is intended to support product design, manufacturing and conformity testing.
Key topics and technical requirements
The standard defines measurable performance criteria and test procedures, including:
- Rated/test volume: Procedure to determine bag capacity (test volume) by controlled filling; bags must have a rated volume not larger than the measured test volume.
- Leakage resistance:
- Freedom from leakage without load - horizontal then vertical inspection after filling to 75% of test volume using coloured water.
- Under load - compressive load test (200 N ±10 N) while filled to 75% of test volume.
- Under impact - drop test from 500 mm ±10 mm onto a smooth rigid surface with 50% test volume.
- Nonreturn valve performance: If fitted, reflux must not exceed 10 ml/min measured under a specified compressive load (100 N ±5 N).
- Attachment and mechanical strength:
- Tests for cutouts, button/buttonhole systems and integral suspensory systems to verify attachment points support the bag.
- Inlet tubing must remain attached under the specified pull/load test.
- Filling performance: Water must start flowing into the bag within 1 minute and the average filling rate must be at least 10 ml/s.
- General test conditions: Standard temperature for testing is 23 °C ± 2 °C. Annex A defines dimensional measurement methods.
The document also specifies required test reporting content and describes apparatus, reagents and step-by-step procedures for reproducible testing.
Applications and users
ISO 8669-2 is primarily used by:
- Manufacturers of urine collection bags for product design, in-house verification and declaration of conformity.
- Independent test laboratories and notified bodies conducting type testing and certification.
- Regulatory and procurement teams assessing compliance for clinical use.
- Quality managers implementing surveillance testing (recommended coordination with ISO 9000 series quality system assessment).
Practical uses include validating leakproofness, mechanical durability, nonreturn valve effectiveness and ensuring safe, reliable performance for clinical and home-care settings.
