IEC60529-2013 Fig 2 IP5X And IP6X Sand And Dust Environmental Test Chamber 1000L
Equipment Overview:
This dust test chamber is designed and manufactured according to IEC60529-2013 Fig 2, and required by IEC 60335-1 Clause 22.1, IEC60598-1-2008, and etc. It is suitable for carrying out the sand dust test for electrical products with the first characteristic numbers of 5 and 6 (IP5X and IP6X).
This test chamber can provide non-laminar dust-carrying vertical circulating airflow, which can be controlled at regular intervals. It is configured with a vacuum pump, operator can choose the vacuum function to pump the air out of the tested product shell, and the pumping volume and pressure difference can be adjustable. In addition, the airflow temperature control device is equipped in the chamber to ensure that the test is carried out under the environmental conditions required by the standard.
In accordance with the requirements of the standard, this test chamber adopts artificially simulated dust environment to test the dustproof ability of the sample, the specific requirements and qualification criteria should be in accordance with IEC60529-2013 or product standard requirements.
Main Technical Parameters:
Model and working size
Model: SN441-1000L
Chamber inner size (mm): 1000×1000×1000 mm (D×W×H)
Structure and material
Basic design principle of this chamber:
Design a cone-shaped funnel with a dust collection port at the bottom, install the suction port of the high-pressure turbine circulation fan at the dust extraction port (bottom), the pumped dust is sent to the top of the inner chamber and then freely spilled from top to bottom, thus repeating the cycles again and again.
Structure and material:
a. Inner chamber material: SUS201 stainless steel mirror panels.
b. Outer chamber material: Painted steel plates.
c. With large observation window on the door.
d. Unique air duct design to ensure that the cabinet produces a concentrated laminar airflow.
e. Basic structure: pretreatment box, test chamber, dust suction port, dust collection box, circulating dust blowing device, vacuum system, dust storage tank, flow valve, heating system, backflow blade, protective match net, concentration meter back dust tube and other components.
Technical parameters
a. Fine dust: below 75um
b. Coarse dust: below 150um
c. The dust concentration in the chamber and pipeline is 2kg/m³
d. Air velocity: less than 2m/s (adjustable)
e. The amount of talc powder: Prepared according to standard requirements (prepared by user, at least 2KG for the first time, as talc powder is not allowed to ship internationally)
f. PLC and touch screen intelligent control system
g. PT100 sensor
h. Over temperature protection function
i. Power phase loss protection
j. Leakage circuit breaker
k. Power supply: Three phase AC380 V / 50Hz
l. Door: Tempered glass door
m. Vacuum pump: 60-600L/H
n. Controller: using programmable controller (this controller has the following multiple arbitrary setting control functions):
① Dust blowing time (stop, blowing) h/m/s adjustable
② Cycle period: arbitrarily adjustable
③ Preset test time: 0s～999h99m99s, arbitrarily adjustable
④ Power supply: off-on-off
o. Metal screen size: nominal wire diameter 50um, nominal distance between wires 75um or less than 150um
p. Fan: All plastic centrifugal fan
Remarks: This test chamber can meet the requirements of degrees of protection provided by enclosures of household appliances, low-voltage electrical appliances, automobile, motorcycle parts and etc.
Structure and Panel Description:
The structure and working principle of the dust test chamber are the same as IEC60529-2013, and equipped with an additional airflow heating device, in order to facilitate the use in the case of low ambient temperature or high humidity. When the system is working, operator first puts the dried standard talc powder (2kg/M3) into the dust test chamber, then puts test sample into the dust test chamber, and then starts the fan to make a high-density dust mist formed in the chamber until the preset test time is reached (Usually 8h).
