Overview
ISO 10813-1:2023 - "Vibration generating machines - Guidance for selection - Part 1: Equipment for environmental testing" provides practical guidance for selecting vibration generating equipment intended for environmental vibration tests. The standard helps buyers, test-lab managers and engineers translate test requirements into functional specifications for the equipment type, model and main components (excluding the control system). It focuses on environmental testing applications and includes informative examples (Annex A).
Key topics and technical requirements
- Scope of selection: Guidance covers equipment type, model choice and major components while excluding control-system specification.
- Vibration test methods: Describes common excitation waveforms used in environmental testing - sinusoidal (fixed and swept), wide‑band random, time‑history, and sine‑beat - referencing applicable IEC test-method standards.
- Types of vibration generators: Reviews the main families - electrodynamic, servo‑hydraulic, and mechanical - and compares their features and typical capabilities.
- Major parameters for selection: Highlights the functional specification elements you must define, including frequency range, maximum acceleration, force, moving mass and size, rated travel, and maximum velocity.
- Component selection: Addresses selection of power amplifiers (for electrodynamic systems) and hydraulic power supplies (for servo‑hydraulic systems), plus other main components.
- Infrastructure verification: Emphasizes the need to check site infrastructure (power, cooling, foundations, access, and fixturing constraints) to ensure the chosen equipment can be accommodated.
- Practical guidance: Includes examples and a non‑mathematical treatment of armature size and infrastructure in the updated 2023 edition.
Practical applications - who uses ISO 10813-1:2023
- Test laboratories selecting or justifying vibration shakers for environmental qualification tests.
- Purchasers and procurement teams evaluating proposals and comparing vendor systems.
- Designers and manufacturers of vibration test systems assessing market and functional requirements.
- Third‑party consultants helping organizations specify equipment or validate supplier recommendations.
Use cases include specifying a shaker for climatic‑chamber vibration, defining performance requirements for functional or endurance tests, and ensuring system compatibility with target test articles.
