How to Set Up a Mechanical Testing Laboratory
A mechanical testing laboratory is built around the loads, speeds, specimen sizes and environments your methods require. Static testing uses electromechanical frames; fatigue and dynamic testing usually need servo-hydraulic or electrodynamic systems with hydraulic power, cooling and foundations. Fixtures, extensometry and calibration are as important as the frames themselves.
Equipment checklist (categories)
- Electromechanical universal testing machines (tension, compression, flexure)
- Servo-hydraulic or electrodynamic fatigue systems
- Test fixtures, grips and custom jigs for components
- Extensometers, strain gauges and data acquisition
- Environmental chambers for temperature-controlled testing
- Vibration and shock systems where product testing is in scope
- Torque, hardness and dimensional measurement equipment
Facility considerations
Servo-hydraulic systems need a hydraulic power unit, cooling water or chillers, noise control and often seismic masses or reinforced foundations. Vibration shakers need isolation and significant electrical supply.
Questions to answer before buying equipment
- Which methods or standards must the laboratory run, and at what edition?
- What sample types, sizes and annual volumes are expected?
- Are accredited (ISO/IEC 17025) results required for customers or regulators?
- What utilities, floor loading, ventilation and environmental control does the space provide today?
- Who will calibrate, service and qualify the equipment, and how quickly can they respond?
- Would outsourcing some work until volumes justify the investment be more economical?
Common questions
- How are test frames calibrated?
- Force measurement is verified against standards such as ASTM E4 or ISO 7500-1 by a qualified calibration provider, typically annually or per your quality system.
