SIRIM (Standard and Industrial Research Institute of Malaysia) has deployed a ZKSSUN low-pressure test chamber in its environmental reliability laboratory to support aerospace, automotive, and electronics testing across Malaysia and ASEAN regions. The system provides controlled altitude simulation combined with temperature cycling for multi-industry validation.
With a temperature range of -70°C to 150°C, the chamber enables precise low-pressure simulation for aerospace avionics, automotive electronics, consumer devices, and packaging systems under realistic high-altitude transport conditions.
Aerospace & Avionics Validation
The system is used to conduct RTCA DO-160G Section 4 altitude simulation tests for drone controllers, avionics modules, and communication systems. Multi-stage altitude conditions from 2,500m to 15,000m are applied to evaluate current stability, signal integrity, and thermal response, supporting airworthiness compliance for regional aerospace suppliers.
Automotive & Plateau Environment Simulation
For automotive electronics such as ECUs and sensors, SIRIM replicates plateau driving conditions (~60 kPa) combined with thermal cycling between -20°C and +60°C. This allows validation of ignition stability, sealing performance, and circuit reliability under low-pressure environments typical of high-altitude regions.
Logistics, Packaging & Medical Transport Testing
Low-pressure conditions equivalent to air freight (up to 18 kPa) are used to evaluate smartphones, wearables, medical consumables, and vacuum packaging integrity. These tests help manufacturers reduce transport-related failures and improve export reliability.
Efficiency & Data Management Improvement
After installation, SIRIM significantly improved testing throughput by localizing low-pressure simulation capabilities. Test cycles were shortened from weeks to 3–5 days, while all results are automatically recorded through LIMS for ISO 17025-compliant reporting and traceability.
