Dust Test Chambers
DNDC529 Series – 500 L to 3600 L
Models for Light-Weight Samples and Reduced Volume
Product Overview
Dust test chambers are designed and manufactured in Canada.
Ensures reliable testing for IP5X / IP6X (IEC 60529) and IP5KX / IP6KX (ISO 20653) standards.
Uniform dust distribution, no dead zones, with excellent repeatability.
Compliance and Applicable Standards
It is crucial to respect occupancy limits to ensure test validity.
IEC 60529 – IP5X and IP6X
Maximum specimen volume: ≤ 33 % of usable chamber volume
Maximum specimen floor area: ≤ 33 % of chamber floor area
ISO 20653 – IP5KX and IP6KX (Road vehicles)
Maximum specimen volume: ≤ 25 % of usable chamber volume
Maximum specimen floor area: ≤ 50 % of chamber floor area
Important: Exceeding these limits invalidates the IP classification.

*Notes:
¹ Recommended talc load is based on standard 2 kg/m³ concentration (higher concentrations supported).
Usable volume is approximately gross volume minus the blower and dust injection system.*
Electrical and Certification Data
Power Supply: 220–240 V AC, 50/60 Hz
Maximum Current: 10 A
Typical Consumption: < 2.2 kW
Acoustic Noise: ≤ 72 dB(A) at 1 m distance (full blower operation)
Documentation supplied with every chamber:
ISO 17025 accredited calibration certificate (issued by Ormity & Dunel accredited laboratory).

Complete risk assessment and test protocol templates.
Operational and Installation Requirements
Minimum 100 mm free space on all six sides of the device under test.
Blower intake must be ≥ 50 mm above the chamber floor (exhaust preferably on opposite wall).
For combined dust + vibration tests (IP6KX): Select the next larger chamber size.
Use talcum powder according to IEC 60529 / ISO 20653 (particle size ≤ 75 µm).
Chamber Sizing Example
Scenario: Automotive Headlamp test (specimen volume = 16.56 L)
Calculation for IEC 60529 (max 33 % occupancy):
Minimum chamber volume required = 16.56 ÷ 0.33 ≈ 50 L
Recommended model: DNDC529/1.0 or larger.
Calculation for ISO 20653 (max 25 % occupancy):
Minimum chamber volume required = 16.56 ÷ 0.25 ≈ 66 L
Recommended model: DNDC529/2.0 or larger.
