GOST 14254 Sand And Dust Test Chamber 2000L for Electronic Products Car
Complied Standards & Clauses
Conforms to IEC60529 Fig 2 IP5X and IP6X, GOST 14254-2015 figure 8 and etc.
Product Overview
The test device is suitable for sealing parts and enclosure’s sand and dust resistance capacity testing of the electrical and electronic products, car and motorcycles spare parts and seals. In order to detect the use, storage, transport performance of the electrical and electronic products, car and motorcycles spare parts and seals under the sand and dust environment.
The test equipment uses intelligent and humanized PLC control system, the inner of the test equipment is made of high quality SUS304 stainless steel, the enclosure is A3 plate electrostatic spraying. And it also has large observation window and manual wiper device. The security protection is good.
Technical Parameters

|
| 1.1 Inner chamber effective capacity | Approx. 2m³ |
| 1.2 Inner chamber sizes | 2000*1000*1000mm(W*D*H) |
| 1.3 External chamber sizes | Approx. 2400*1500*1900 mm(W*D*H) |
| 2. Function parameters | |
| 2.1 Working room temperature | RT+10℃～+70℃ |
| 2.2 Product vacuum degree | ≤60KPa |
| 2.3 Dust composition | Talcum powder |
| 2.4 Dust particle composition |
Dry talc that can pass through a square mesh sieve with a mesh size of 75µm and a wire diameter of 50µm |
| 2.5 Dust concentration | 2～4kg/m3 |
| 2.6 Air flow meter | Digital flow meter |
| 2.7 Air flow rate | 1.5 m/s (Adjustable range: 0 ~ 4.99 m/s) |
| 2.8 Time Control | Dust blowing control cycle: 1s ~ 99h (adjustable), test time: 1s ~ 99h (adjustable), vibration time: 1S ~ 99H (adjustable) |
| 2.9 Metal Screen | Nominal wire diameter: ≥50μm, standard spacing between wires: ≥75μm. |
| 2.10 Sand and dust air circulation device | The circulating air duct and high-power mixed flow fan have an exhaust volume of 80 times the volume of the sample’s shell, and the exhaust speed does not exceed 60 times the volume of the shell per hour. The air flow speed can make the dust evenly distributed in the test chamber. The air flow in the test chamber is mainly vertical airflow from top to bottom, rather than laminar flow. |
| 2.11 Sample rack |
2 pcs |
| 2.12 Dust drying system | The equipment is equipped with a dust drying and heating device. There is a heating button on the controller control screen. When the dust is found to be a little damp during the test, the heating button on the control screen can be turned on to start the dust heating device to dry the dust. The button can be turned off after the dust is dry. The drying process will not affect the test process, effectively ensuring the dust concentration in the test chamber and the accuracy of the test data. |
| 2.13 Dust replacement method | Manually change dust, dust can be easily replaced at any time |
