Overview
EN ISO 20695:2020 - Enteral feeding systems: Design and testing is the European adoption of ISO 20695:2020 prepared by CEN/TC 205 and ISO/TC 84. The standard specifies requirements and test methods for enteral feeding systems, including enteral giving sets, enteral extension sets, enteral syringes, enteral feeding catheters, and enteral accessories. It is explicitly not applicable to oral syringes. EN ISO 20695:2020 replaces earlier EN standards (EN 1615 and EN 1618).
Key topics and technical requirements
The standard covers general design, safety and performance topics relevant to enteral feeding systems:
- General requirements: risk management, usability, materials, cleaning/disinfection, sterility, packaging, biological safety, corrosion resistance and surface finish.
- Information and labeling: marking, symbols, labelling and instructions for use required from the manufacturer.
- Specific device requirements:
- Enteral giving sets and extension sets: inlet/outlet/access port design, tensile strength and leakage testing, plus required manufacturer information.
- Enteral syringes: outlet port design, dose accuracy requirements and marking.
- Enteral feeding catheters: access ports, tensile properties, leakage performance, flow rate, designated size, and detectability (radiopacity/MRI compatibility where applicable).
- Retention-balloon catheters: balloon burst volume, recommended inflation volume, inflation-system performance, balloon concentricity and integrity in simulated gastric fluid.
- Test methods and normative annexes: the standard contains detailed test methods (normative annexes) for corrosion resistance, tensile testing, liquid leakage under pressure, flow-rate determination, catheter diameter measurement, balloon burst and performance tests, and others.
Applications and who uses it
EN ISO 20695:2020 is intended for stakeholders involved in the lifecycle of enteral feeding devices:
- Manufacturers and designers of enteral giving sets, syringes, catheters and accessories - to guide product design, risk mitigation and validation testing.
- Quality assurance and regulatory teams - to demonstrate conformity with recognized design and testing practices used in Europe and internationally.
- Test laboratories and notified bodies - for performing and assessing the standardized test methods contained in the normative annexes.
- Healthcare procurement and clinical engineers - to specify compliant products and evaluate device compatibility and safety.
- Clinicians and patient-safety officers - for understanding device performance parameters relevant to clinical use.
Related standards
- ISO 20695:2020 is the international standard; EN ISO 20695:2020 is the CEN-endorsed European version (superseding EN 1615 and EN 1618).
- Manufacturers should consider this standard alongside other applicable medical device, sterility, biocompatibility and connector/compatibility standards when seeking regulatory compliance (e.g., national medical device regulations).
