GB/T 12085.1-2022 "Optics and photonics—Environmental test methods—Part 1: Terminology, scope of tests" serves as the foundational framework for the entire series of standards. It specifies unified terminology, definitions, general test procedures, and environmental test marking methods for the series, providing a common regulatory framework for the implementation of subsequent specific environmental tests (such as salt spray, sand and dust, mechanical stress, etc.). This document applies to optical and photonic instruments, and its relevant terminology and procedures can also be referenced in other fields such as mechanical, chemical, and electronic equipment. As a foundational component, it does not directly specify particular testing instruments but provides the terminological and procedural basis for the standardized use of all specialized test equipment involved in the series (such as salt spray test chambers, sand and dust test chambers, vibration test systems, etc.).
