Blowing Sand and Dust Test Chambers for Environmental IP Dustproof
Testing
Features
1. Built-in chest configuration
2. Designed to be used under extreme conditions
3. The interior chamber is built with 304 grade stainless steel
treated for erosion resistance and high temperature application to
avoid creep failure
4. The exterior chamber is made of steel plates with electrostatic
powder coating offering high wear resistance
5. Acrylic glass door with with a window wiper fitted to the front
of the test chamber to view the specimen under testing
6. Electrical section installed in the switch cabinet and fitted to
the test chamber side wall
7. Modular design, ready to be installed
What is a Sand and Dust Test Chamber ?
The Sand and Dust Environmental Test Chamber simulates extremely
sandy, dusty and desert-like environments to test product’s ip dust
proof/resistance performance (seal integrity) in accordance with
related IEC, ASTM, and ISO standards.
Sand and Dust Test Chamber from ATMARS meets Automotive,
Electronic, Military Equipment and other test specifications.
Powerful blowers intermittently blow compressed air up through
finely powdered sand and dust and then allow the sand and dust to
settle back down covering the product. Concentration of dust can be
easily varied by changing the air pressure and the amount of the
blowing time.
| IP Code First digit: Solid Particle Protection | ||
| Level | Effective Against | Description |
| X | - | X means there is no data available to specify a protection rating with regard to one of the criteria. |
| 0 | - | No protection against contact and ingress of objects. |
| 1 | >50 mm | Any large surface of the body, such as the back of a hand, but no protection against deliberate contact with a body part. |
| 2 | >12.5 mm | Fingers or similar objects. |
| 3 | >2.5 mm | Tools, thick wires, etc. |
| 4 | >1.0 mm | Most wires, slender screws, large ants etc. |
| 5 | Dust protected | Ingress of dust is not entirely prevented, but it must not enter in sufficient quantity to interfere with the satisfactory operation of the equipment. |
| 6 | Dust tight | No ingress of dust; complete protection against contact (dust tight). A vacuum must be applied. Test duration of up to 8 hours based on air flow. |
