Overview
ISO 20695:2020 - Enteral feeding systems - Design and testing specifies design, safety and testing requirements for enteral feeding systems, including enteral giving sets, enteral extension sets, enteral syringes, enteral feeding catheters and enteral accessories. The standard aims to reduce clinical risk (including wrong‑route administration) by defining functional requirements, usability, materials, biological safety, packaging, labeling and prescriptive test methods. Note: ISO 20695:2020 is not applicable to oral syringes.
Key topics and requirements
- General requirements: risk management, usability engineering, information supplied by the manufacturer (marking, symbols, labelling, instructions for use).
- Materials and biological safety: biocompatibility, cleaning/disinfection, sterility and corrosion resistance.
- Mechanical and fluid performance: tensile strength, leakage resistance, flow rate and dimensional (outer diameter) verification.
- Enteral syringe specifics: outlet port design, dose accuracy and marking requirements.
- Enteral catheter specifics: access ports, tensile properties (with/without introducer systems), flow characteristics, designated size, and requirements for catheters with retention balloons (burst volume, recommended inflation volume, inflation system performance, concentricity, integrity in simulated gastric fluid).
- Test methods: normative annexes provide test procedures for corrosion resistance, tensile testing, leakage under pressure, flow rate measurement, outer diameter determination, balloon testing and more.
- Usability and connector safety: specifies use of enteral‑specific small‑bore connectors to help prevent misconnections.
Practical applications
- Manufacturers use ISO 20695:2020 to design and validate enteral feeding products that meet international safety and performance expectations.
- Test laboratories and quality teams apply the annexed test methods for product type approval, verification and conformity testing.
- Regulators and notified bodies reference the standard during conformity assessment for market access.
- Procurement and clinical engineering teams rely on the standard to evaluate device specifications, labeling and compatibility to reduce patient risk.
- Clinicians and hospitals benefit indirectly through safer, standardized devices that help prevent wrong‑route administration.
