ISO 17510:2025

Overview

ISO 17510:2025 - Medical devices: Sleep apnoea breathing therapy - Masks and application accessories defines safety, performance and information requirements for masks and associated application accessories used to connect sleep apnoea breathing therapy equipment to a patient. It covers nasal masks, exhaust ports, headgear, connectors and related parts required for therapy delivery. The standard takes priority over ISO 18190, does not cover oral appliances, and aligns with IMDRF essential and labelling principles (see Annex I).

Key topics and technical requirements

ISO 17510:2025 addresses design, testing and manufacturer information for masks and accessories. Major technical topics include:

• Construction and connectors: requirements for mask connectors and patient-connection elements to ensure compatibility and safe attachment to therapy equipment.
• Biocompatibility: gas-pathway and patient-contacting materials are evaluated in line with ISO 18562-1 and ISO 10993-1 risk-management principles.
• Protection against rebreathing: design requirements for normal and single-fault conditions to limit carbon dioxide rebreathing (see Annex F).
• Anti-asphyxia valves: definitions and pressure testing procedures (Annex D) to allow spontaneous breathing if therapy flow fails.
• Cleaning, disinfection and sterilization: processing guidance for single-patient and multiple-patient reuse (references to ISO 17664 series).
• Breathing system filters and resistance to flow: requirements and test methods (Annex C, Annex E) for pressure drop and filter performance.
• Audible acoustic energy (noise): measurement and limits, with referenced acoustic standards (ISO 3744, ISO 4871 and IEC 61672-1; see Annex G).
• Manufacturer information and labelling: content and presentation expectations, harmonized with ISO 20417 (see Clause 4 and Annex H).
• Normative test procedures: exhaust flow testing, CO2 rebreathing, valve testing and uncertainty treatment (Annexes B–G).

Practical applications and who uses this standard

ISO 17510:2025 is essential for:

• Medical device manufacturers designing and producing CPAP/BiPAP masks, headgear and connectors.
• Regulatory and conformity assessment bodies evaluating safety and labelling compliance.
• Clinical engineers and procurement teams specifying compatible masks and accessories for sleep clinics and hospitals.
• Test laboratories performing normative assessments (exhaust flow, pressure drop, noise, biocompatibility).
• Standards writers and product safety specialists harmonizing device documentation with IMDRF principles.

Adopting ISO 17510 helps ensure patient safety, interoperability with sleep apnoea breathing therapy equipment (ISO 80601-2-70), and clear manufacturer instructions for processing and use.
