ISO 10109:2024

Overview

ISO 10109:2024 - Optics and photonics - Guidance for the selection of environmental tests - provides structured, practical guidance for choosing environmental tests and test parameters for optical and photonic instruments. The third edition (2024) supplies tables that link environmental influences and standard environments to appropriate test methods, helping manufacturers and test laboratories verify the reliability of optical, mechanical, chemical and electrical properties under simulated conditions. The document complements the environmental test methods specified in ISO 9022 and adds parameters specific to optics and photonics.

Key topics and requirements

• Selection tables for environmental tests: Ready-to-use tables that map environmental influences (temperature, humidity, pressure, solar irradiance, precipitation, dust, etc.) to test parameters and severity levels.
• Standard environments: Classifications (Standard environment 1–11 and others) describing typical use cases - from extreme cold (e.g., arctic) to weather-protected technical climates and high-altitude conditions - with associated ranges for temperature, humidity and other influences.
• Technical requirements and degrees of severity: Definitions of technical requirements, conditioning methods, states of operation, and status-after-test codes to standardize pass/fail criteria.
• Compatibility with ISO 9022: Environmental test methods from ISO 9022 (all parts) are referenced for detailed procedures; ISO 10109 provides guidance on assigning those methods to areas of application.
• Examples and guidance annexes: Informative Annex A (examples of test selection) and Annex B (examples of selection of standard environmental tests) to assist practical implementation.
• Focus on reliability: Tables specify what to verify to ensure instruments remain within defined performance specifications when exposed to environmental influences.

Applications and who should use it

ISO 10109:2024 is intended for professionals involved in the design, testing, procurement and certification of optical and photonic products, including:

• Manufacturers of optical systems, lenses, imaging sensors, lasers and photonic assemblies
• Environmental and qualification test laboratories and QA teams
• Product design and reliability engineers defining verification plans and test matrices
• Procurement specialists and system integrators specifying environmental requirements for components and instruments
• Aerospace, defense, automotive, medical device and industrial photonics sectors where environmental robustness is required

Practical uses include selecting test suites for environmental qualification, defining conditioning methods and severity levels, and aligning vendor testing with buyer expectations.
