IEC 68 Impact Test Machine: Mechanical Shock Tester & Free-Fall Impact Test Equipment

Preface

Reliability validation has become an indispensable link in the R&D and mass production of electronic, automotive, military and packaging products. During transportation, handling, accidental drops and field operation, finished products and internal components will suffer instantaneous high-intensity mechanical shocks, which easily trigger hidden failures such as structural cracking, loose solder joints, component detachment and functional interruption. To quantify product anti-shock performance with unified, internationally recognized test specifications, IEC 68 (official serial standard IEC 60068) and supporting military standard MIL-STD-202F are widely adopted across global industries. The free-fall mechanical shock tester is the core precision testing instrument fully compliant with these standards, delivering repeatable, comparable shock impact data for product design optimization, incoming quality inspection and global certification. This article systematically interprets IEC 68 standard requirements, machine working principles, core functions, industrial application scenarios, and highlights the mature LONROY IEC 68 shock test equipment for laboratory and factory production lines.

Ⅰ. Full Overview of IEC 68 Standard for Mechanical Shock Testing

IEC 68 refers to the IEC 60068 series international environmental testing standard issued by the International Electrotechnical Commission, among which IEC 60068-2-27 Test Ea: Shock is the core clause governing mechanical shock and free-fall impact testsIEC Webstore. This standard unifies the complete test workflow for evaluating the anti-shock capacity of electrical, electronic components and complete equipment, covering specimen mounting rules, standard shock pulse waveforms, adjustable severity grades (peak acceleration & pulse duration), multi-axis test requirements, waveform tolerance limits and data recording specifications.

Core Standard Value

Standardized test methodology: Eliminates result deviation caused by inconsistent equipment, operation height and impact buffering materials among different laboratories.

Global data compatibility: Test reports complying with IEC 68 are recognized by certification bodies, overseas purchasers and cross-border trade customs.

Matching military validation: Cooperates with MIL-STD-202F electronic component shock specification to cover both civil industrial and military product reliability verification demands.

Supported Test Modes Defined by IEC 68

Repetitive mechanical shock test for component fatigue assessment

Free-fall vertical impact test for finished consumer electronics and packaging boxes

Multi-directional X/Y/Z orthogonal impact test to simulate all-angle accidental collision

Dynamic waveform acquisition to record real-time acceleration, pulse width and impact energy

Ⅱ. IEC 68 Compliant Mechanical Shock Tester: Equipment Introduction

The IEC 68 Impact Test Machine (also named Mechanical Shock Tester, Free-Fall Impact Test Equipment, Shock Test Device) is a dedicated dynamic force simulation instrument independently developed to fully meet IEC 60068-2-27 and MIL-STD-202F regulatory thresholds. Taking the mature LONROY model as the benchmark, the equipment integrates servo lifting module, instantaneous magnetic release mechanism, waveform shaping buffer, high-precision acceleration sensor, industrial touch control system and real-time data acquisition software, forming a closed-loop free-fall shock test system with stable impact output and ultra-high test repeatability.

Complete System Composition of LONROY Shock Test Device

Heavy-duty steel main frame: Anti-deformation thickened base with built-in air spring vibration isolation, no special foundation required for laboratory placement.

Servo lifting platform: Precise height adjustment via ball screw, digital height locking, error controlled within ±1mm.

Instant magnetic release unit: Zero-delay unlocking to realize true free-fall without lateral friction interference.

Replaceable waveform buffer pads: Supports half-sine, trapezoidal and triangular shock waveforms required by IEC 68.

High-speed data acquisition module: Matching industrial accelerometer to capture full shock waveform curves.

PLC computer control system: Touch screen operation, automatic parameter storage and one-click test execution.

Full safety protection assembly: Emergency stop switch, anti-secondary rebound hydraulic brake, safety isolation fence to prevent accidental injury.

Compared with ordinary low-cost drop testers, LONROY’s IEC 68 shock equipment strictly calibrates shock pulse tolerance in accordance with standard clauses, avoiding distorted waveforms and invalid test data, and can directly output certification-grade test reports for third-party inspection institutions.

Ⅲ. Working Principle of Free-Fall Mechanical Shock Tester

The entire test logic follows the free-fall impact dynamics model specified in IEC 68 standard test procedures:

Specimen clamping: Fix the test sample to the lifting platform via customized universal fixture, completing X/Y/Z three-axis positioning according to product test requirements.

Height parameter setting: Input target drop height, preset shock times, expected peak acceleration and pulse duration on the control software; the servo system automatically lifts the platform to the calibrated height.

Free release impact: The magnetic locking mechanism instantly releases the platform, which falls vertically under pure gravity and collides with the standardized waveform buffer installed on the base.

Standard shock pulse generation: The elastic buffer converts gravitational potential energy into controllable transient impact force, producing standard shock waveforms defined by IEC 68. The acceleration sensor mounted on the platform synchronously collects real-time impact signals.

Anti-rebound braking: The built-in hydraulic brake locks the platform immediately after the first impact, eliminating secondary rebound interference that would destroy test waveform consistency.

Data analysis & storage: The host software automatically calculates peak G value, pulse duration, impact energy and waveform fitting curve; all raw data can be saved, graphed and exported for traceability.

Common calculation algorithms embedded in LONROY control software include waveform envelope fitting, peak acceleration extraction and impact energy integral calculation, fully meeting the data recording accuracy requirements of IEC 68 and MIL-STD-202F.
