ISO 8600-1:2015

Overview

ISO 8600-1:2015 - "Endoscopes - Medical endoscopes and endotherapy devices - Part 1: General requirements" provides core definitions and general requirements for the design, construction, testing and information supplied for medical endoscopes and endotherapy devices. It is the foundational part of the ISO 8600 series and sets baseline expectations for safety, usability and performance for rigid and flexible endoscopes used in clinical practice.

Key topics and technical requirements

• Scope and definitions: Clear definitions for terms such as endoscope, endotherapy device, rigid/flexible endoscope, insertion portion, instrument channel, working length, field of view, direction of view, French (Fr) sizing, and controllable portion.
• Design and safety requirements: Surfaces and edges must avoid pores, cracks and tooling residues to prevent injury or contamination. Devices must be designed to minimize unintentional injury during intended use.
• Dimensional requirements:
  • Maximum insertion portion width must not exceed the value stated in the instruction manual.
  • Minimum instrument channel width must not be smaller than the value stated in the instruction manual.
• Optical performance tolerances:
  • Field of view deviation from the manufacturer-stated value shall not exceed 15% unless otherwise specified.
  • Direction of view deviation for rigid endoscopes shall not exceed 10° unless otherwise specified.
• Functional controls: Requirements for deflection control systems (up/down, right/left), arrangement of hand wheels and maximum deflection angles for controllable portions.
• Safety and biological compatibility: Conformity with IEC 60601-2-18 for medical electrical safety and with ISO 10993-1 for biological evaluation of materials contacting the patient.
• Fittings/connectors: Requirements for fittings or connectors for liquid or gaseous media, and guidance on associated risk management.
• Testing, marking, documentation and packaging: Specifies test methods, minimum marking and legibility, instruction manual content, and packaging requirements. Annex A gives guidance on risk management for system connectors.

Practical applications and users

ISO 8600-1:2015 is used to:

• Guide medical device manufacturers in design verification, risk assessment and product labeling for endoscopes and endotherapy accessories.
• Inform test laboratories and quality/validation teams when performing dimensional, optical and safety testing.
• Support regulatory submissions and compliance activities (CE marking, FDA dossiers) by documenting adherence to recognized international requirements.
• Help hospital procurement, clinical engineers and endoscopy departments evaluate device specifications and compatibility with existing systems.
• Aid standards writers and risk managers when applying ISO 14971-based risk management principles to endoscopic connectors and interfaces.

Related standards

• ISO 8600 series (Parts 2–7) for particular requirements and test methods (e.g., field of view, maximum width, optical resolution, vocabulary).
