Product Overview

The walk-in sand and dust test chamber is a professional piece of equipment designed to simulate sand and dust environments. It is primarily used to test the sealing performance of product enclosures, especially for evaluating the IP5X and IP6X dust protection ratings specified in ingress protection (IP) standards. It is widely applied in industries such as electronics, automotive, electrical appliances, lighting, and new energy products.

Product Features

The walk-in sand and dust test chamber combines robust construction with advanced automation to deliver reliable, repeatable tests:

Customizable interior capacity – Workroom dimensions are fully customizable based on customer requirements (standard options available upon request).
Personnel access door – Allows operators to place and inspect large test samples directly inside the chamber.
Wide temperature range – RT+10°C to 40°C (extended ranges available on request).
Dust feeding modes – Supports both powder blowing and free dust settling, selectable as continuous or periodic cycles.
Vacuum system – Built-in vacuum pump with adjustable vacuum degree (0–10 Kpa) and air extraction rate (0–6000 L/h) for testing specimens that require negative-pressure sealing verification.
Test duration flexibility – Timer range from 0 to 999 hours (or 0–9999 H) to accommodate both short and long-term test protocols.
Dust concentration control – Typical dust concentration of 2–4 kg/m³ using dried talcum powder (200-mesh or 75-μm sieve).
Durable stainless steel interior – The workroom is constructed from SUS304 stainless steel to resist corrosion and facilitate cleaning.
Touch-screen controller – Intuitive interface with programmable test cycles, real-time monitoring, and data logging capabilities.
Safety protections – Equipped with leakage protection, short-circuit protection, and low-water level alarms for the dust-handling system.
Compressed air dust removal – Optional feature to blow out residual dust from internal surfaces after testing, reducing manual cleaning.

Test Standards

The walk-in sand and dust test chamber is designed to comply with the following international and domestic standards, ensuring globally recognized test results:

IEC60529:1989 + A1:1999 + A2:2013 – Degrees of protection provided by enclosures (IP Code), specifically IP5X (dust-protected) and IP6X (dust-tight).

GB/T4208-2017 – Chinese national standard equivalent to IEC60529, covering enclosure protection ratings.

GB/T2423.37-2006 – Environmental testing for electric and electronic products – Dust test method.

ISO 20653 – Road vehicles – Degrees of protection (IP code) – Protection against dust.

MIL-STD-810 (Method 510.7) – Sand and dust testing for military equipment (optional configuration available).

The chamber reliably reproduces the required test conditions: airflow velocity not exceeding 2 m/s, dust particle size passing through 75-μm mesh with 50-μm wire diameter, and dust concentration maintained at 2–4 kg/m³ throughout the test. All critical parameters can be preset on the touch-screen controller, ensuring full standard compliance with minimal operator intervention.

FAQ

Q1: What types of products are typically tested in a walkin sand and dust test chamber?

A: This walk-in sand and dust test chamber is ideal for large or heavy products such as automotive lamps, steering systems, electrical control cabinets, energy storage containers, outdoor telecom enclosures, military shelters, and aerospace components. It is also widely used for testing LV electrical devices, motors, and instruments that require IP5X or IP6X certification.

Q2: How is the dust circulated and collected inside the chamber?

A: The chamber uses a highpower circulation fan to blow dust through the test area. Dust falls onto a funnelshaped bottom and is recirculated, minimizing waste. A vibrating motor prevents dust from clumping. After the test, residual dust can be removed using an optional compressed air blowdown system or a vacuum cleaner.

Q3: Can the chamber test samples that require vacuum sealing?

A: Yes. The builtin vacuum system provides adjustable vacuum degree (0–10 Kpa) and extraction rates up to 6000 L/h, making it suitable for testing seals, gaskets, and enclosures that must maintain integrity under negative pressure.

Q4: What utilities are required for installation?

A: The standard model requires a 220V 50Hz power supply with approximately 2.0 kW capacity (higher for larger units). The chamber should be placed on a level, wellventilated floor with adequate drainage. A dedicated water source may be needed if dust conditioning or washdown features are included. The required floor space depends on the customized chamber size – our engineers will provide a layout drawing based on your specific dimensions.

Q5: Is the chamber easy to operate?

A: Absolutely. The 7inch touchscreen controller offers preset test protocols for IP5X and IP6X, plus custom programming options. The controller supports realtime monitoring, data logging, and alarm notifications. Most operators become proficient after a short training session.
