Introduction
From desert installations to coastal industries, electronic products face a spectrum of environmental stressors that challenge their reliability and lifespan. To simulate these conditions in a repeatable and standardized way, the IEC 60068-2 series defines rigorous environmental test methods for both particulate intrusion and corrosive gas exposure.
In this article, we'll unpack the key IEC 60068-2 test methods related to dust, sand, and noxious gases, explain why each matters in real-world deployments, and show how LIB's specialized test chambers make it easy to comply-while delivering reliable, repeatable data.
Part 1: Dust and Sand Testing – Why It Matters
Real-World Risk: Dust Is Everywhere
Fine dust and sand are ubiquitous in outdoor and semi-outdoor environments-from base stations in desert climates to smart sensors in roadside cabinets. Dust infiltration can:
Abrade mechanical parts and sensitive optics
Compromise IP-rated enclosures
Lead to overheating or contact failure in electronics
Standard in Focus: IEC 60068-2-68 (Test L)
This standard simulates airborne particulates under different motion and pressure conditions:
La – Settling Dust: Fine dust suspended in still air, settling on test items
Lb – Free-Falling Dust: Simulated intermittent or light dust exposure
Lc – Blown Sand: High-velocity sand impacting surfaces, mimicking desert winds
Test Solution: LIB Dust-Proof Test Chamber

Part 2: Corrosive Gas Testing – Why It Matters
The Silent Enemy: Atmospheric Gases
Even at low concentrations, industrial gases like SO₂, H₂S, Cl₂, and NO₂ can initiate corrosion on metal surfaces, degrading electronics over time. Affected components include:
PCBs and connectors
Relay contacts and wire terminations
Solder joints and housing materials
