UN38.3 Testing: What Makes Our Testing Services Different?

01
Quality

Our experienced engineers ensure that your cells and packs undergo electrical and mechanical safety testing so that they can be brought to market in compliance with the highest safety standards.

02
Agile Testing

While we provide full UN38.3 compliance certification, we also offer rapid individual testing for early prototype validation. Driven by lean internal workflows and direct engineer to engineer communication, your project moves through our lab with maximum speed and zero administrative delays.

03
Purpose Built Infrastructure

We deliberately optimize our equipment and processes for cells and small modules. This absolute focus guarantees state of the art, high precision testing environments and highly specialized handling tailored precisely to your component size.

Battery Validation and Pre-Compliance Testing

Battery validation can be performed as a single test for early-stage prototypes or as a full UN38.3 testing sequence. Stress assessments are carried out within a unified infrastructure, ensuring reliable and consistent results. We also offer targeted pre-testing to prepare your batteries for all common battery safety standards (IEC 62619, IEC 62133-2 etc.).

  • T.1 Altitude Simulation

    This test simulates air transport under low pressure conditions. The batteries are exposed to a low pressure of 11.6 kPa for at least 6 hours.The batteries are exposed to a low pressure of 11.6 kPa for at least 6 hours.

  • T.2 Thermal Test

    This test assesses battery seal integrity and internal electrical connections. The test is conducted using rapid and extreme temperature changes. The test object undergoes 10 cycles between -40 °C and +72 °C.

  • T.3 Vibration

    The batteries are subjected to sinusoidal vibrations for 9 hours to simulate the mechanical stress during transport.

  • T.4 Shock

    The batteries are subjected to a total of 18 mechanical shock pulses of 150G along three axes to simulate sudden impact loads.

  • T.5 External Short Circuit

    At an ambient temperature of 57 °C, a low impedance external short circuit of less than 0.1 Ohm is induced to verify safety during electrical faults.

  • T.6 Impact and Crush

    The battery is mechanically deformed either by a defined mass impact or hydraulic pressing force to evaluate the reaction to severe physical damage.

  • T.7 Overcharge

    The battery is charged for 24 hours at twice the rated current to evaluate its reaction to a charger malfunction.

  • T.8 Forced Discharge

    A battery is artificially deeply discharged to simulate the behavior during forced polarity reversal within a battery assembly.

Precision Testing,
Audit-Ready-Compliance

Technical Validation & High-Resolution Telemetry

Our validation stations support cells, packs, and modules. They provide full raw telemetry, including voltage curves, current profiles, and multi-point thermal mapping, for comprehensive performance evaluation and verification. High measurement resolution enables the precise capturing of critical cell behaviors, such as separator collapse, internal shorts, vent activation behavior, and battery management system response characteristics.

Regulatory & Audit-Ready Documentation

Each validation sequence generates serialized, audit-ready documentation aligned with international transport and safety standards. Reports include complete test traceability, data from calibrated instrumentation, and comprehensive test reports suitable for certification bodies and supply chain audits.
