Standard
IEC60068-2-68 Test L:Dust and Sand La2, IEC60529 Degrees of protection provided by enclosures (IP Code), IEC60034-5,IEC60598-1 and ISO/DIS12346.
Application
The sand and dust test chamber is designed to verify the sealing performance of the enclosures of electronics. This is particularly important for equipment used outdoors such as automobiles, motorcycles, etc.
Test Sample
Electrical and electronic products.
Feature
The main effects of sand and dust on the product are as follow
1. Intrude into sealing element and enclosures
2. Interfere with electrical performance
3. Block and wear bearings and other moving parts
4. Abrasive surface, lubricant pollution
5. Blocking ventilation opening, pipeline, filters, and other operation holes
Main Features and Functions of Sand and Dust Chamber
1. The chamber body is made of stainless steel
2. PLC control, touch screen operation, it can be controlled by manual and automatic operation
3. Large observation window with wiper
4. Configuration of vacuum pumping system
5. The size of the inner chamber can be customized according to the size of the test sample.
