What the Specs Mean in Practice
Platform Size
An 8 m × 6 m HT250 cast iron bed accommodates full axle assemblies, sub-frames, and multi-point fixture rigs simultaneously — no reconfiguration between tests.
Force Capacity
±400 kN static per channel handles passenger car AND heavy commercial vehicle (HCV) components under the same setup without capacity limitations.
8-Channel Controller
Multi-point loading replicates real-world road load data (RLD) — simultaneous vertical, lateral, and longitudinal inputs across the component in a single test run.
Waveform Flexibility
Sine, random, user-defined, and mixed profiles — supports OEM-specific load spectra, PSD profiles, and custom fatigue sequences without additional setup.

Why Microlab
ARAI-Equivalent Capability. Private-Sector Speed and Pricing.
India’s government labs are benchmark references — but queue times and inflexible schedules drive engineering teams toward private accredited facilities. Microlab closes that gap.
±400 kN Capacity
Handles both passenger car and heavy commercial vehicle components without force-range limitations. No need to split testing across multiple labs.
8-Channel Controller
Multi-point simultaneous loading replicates real-world road load data — vertical, lateral, and longitudinal inputs in a single test event. Not sequential, not estimated.
8000 × 6000 mm Platform
Full sub-assemblies — complete axle, suspension corner, or seat module — fit on the HT250 cast iron bed without spatial constraints or fixture compromises.
Combined Environment
Vibration and thermal and humidity simultaneously in a single test run. Accelerated life testing that reflects real operating conditions, not isolated stress modes.
IP69K Capable
Highest standard of water ingress protection testing — 80°C water at 80–100 bar. Critical for EV connectors, underbody electronics, and off-highway components.
Private-Sector Pricing
Test results without government lab overhead. Transparent quotation, confirmed scope before testing begins, no hidden charges on report issuance.
Fast Turnaround
No government queue. Test scheduling within days, not months. Urgent project support available. Direct engineer-to-engineer communication on test configuration.

Defining Your Test Program
Key variables we work through before testing begins
Component Type
Automotive assemblies (suspension, chassis, brackets), industrial equipment (frames, housings, actuators), consumer products (furniture, appliances), infrastructure components (poles, beams, connections).
Load Path & Duty Cycle
Static (proof load, ultimate), cyclic (constant amplitude, variable amplitude, spectrum loading), combined (tension + bending, axial + torsion), with defined load levels and cycle targets.
Fixture Design
In-house fixture engineering ensures load application replicates real-world constraints. Custom jigs, grips, loading shoes, and reaction frames designed per component geometry.
Failure Criterion
Complete fracture, crack initiation (visual or instrumented), stiffness degradation (%), permanent deformation limit, functional loss (e.g., seal failure, bearing play). Defined before test start.
Data Acquisition
Multi-channel DAQ: load, displacement, strain gauges, accelerometers, temperature, cycle count. Real-time monitoring with peak/valley capture and time-history recording.
Correlation Studies
Comparison between FEA predictions and physical test results. Strain gauge rosettes at critical locations, displacement measurement via LVDT, and correlation reporting for design validation.

Structural vs. Product Validation vs. Environmental
Choosing the right test program for your component
Structural Testing
This page
Applies mechanical loads (static, cyclic, multi-axis) to components or assemblies to validate structural integrity, endurance life, and load-carrying capacity. Focus: will it break under service loads?
Corrosion vs. Environmental Testing
Full qualification programs
Manages the complete qualification program: DV (design validation), PV (production validation), PPAP documentation. May include structural tests as part of a broader test matrix with dimensional, environmental, and functional tests.
Metallography vs. SEM/EBSD
Exposure-based qualification
Subjects products to environmental stresses: temperature cycling, humidity, UV, salt spray, vibration. Focus: will it survive the environment? — not the structural load. Often combined with structural testing for comprehensive qualification.
