A dust test chamber is essential for the quality assurance of many products available in the current market. The products that go through sand and dust testing tend to be more durable and popular in markets due to their resilience and high finishing quality, tested and ensured in the Dust test chamber through sand and dust testing. In this article, we will investigate the LISUN SC-015 Dust-proof test chamber (Sand Dust Chamber) for its abilities and performance for performing such tests.

Dust test chamber:

The dust test chamber is the name of “Sand Dust Test chamber”, which simulates the destructive effect of natural sand, dust, and wind climate on products for sand and dust testing. This is suitable for checking the shell sealing performance of products. The dust test chamber is mainly used for the ip5x and ip6x, which are two grades of test in the standard of shell protection. 

Working principle of dust test chamber:

The Dust test chamber utilizes a fan. A concentration of dust is thrown upon the surface of the object being tested, at a certain velocity. The ability to defend the abrasive or blocking effects of grit, and the ability to store and operate to test the ability of these test specimens to be exposed to the infiltration of dust particles in products under the action of dry sand or dust-filled atmospheres.

Test object:

Mobile phones, electrical items, and other products are tested in the sand dust environment. Also, the sealing performance in the use, storage, and transportation of the automobile, motorcycle parts, seals, and so on are tested out in the sand and dust testing environment.

Sand and Dust Testing:

Sand and dust testing can determine the resistance of the sand and dust. Usually, hot and dry environments have blowing dust and sand. It can also exist seasonally in other regions of the world. Natural sand and dust storms are a crucial factor in the development of material.

Some common features of sand and dust testing:

Temperature – The tests are conducted with the test item at standard ambient, high operating, and storage conditions.

Relative Humidity – High relative humidity may be a reason for caking of dust particles. Thus, the test chamber RH is set to not exceed 30 percent.

Air Velocity – Decreased air velocity maintains the temperature conditions and a higher air velocity as a typical desert environment. For typical testing, test area is provided with uniform speeds.

Duration – Normally, the sand and dust tests are performed for a minimum of 90 minutes per each vulnerable face of the item at hand and must be re-orientated.

Why perform sand and dust testing?

Sand and dust environments can wreak an equipment. Some adverse effects are the penetration of the particles in cracks, crevices, and bearings. Particles may hinder the openings and filters, prompting a fire hazard because of the restricted ventilation or cooling. They might also interfere with matting and moving parts.

Purpose

1. Dust (< 150μm) procedure. Performing this test helps evaluate the ability of the material to resist the effects of dust that may obstruct openings, penetrate through bearings, cracks, joints, and evaluate the effectiveness of filters.
2. Sand (150 to 850μm particle size) procedure. This test assesses the ability of a material to be stored and operated in sandstorms or similar conditions, without experiencing degrading performance, effectiveness, reliability, and ease of maintenance due to erosion or blockage of large, sharp-edged particles.

Electronic devices such as mobile phones, tablets, and cameras have become an integral part of our daily essentials, both professionally and in everyday life. The demand for rugged devices that can be used outdoors as well as under demanding circumstances at work has increased. The LISUN SC-015 Dust-proof test chamber (Sand Dust Chamber) can help manufacturers cater to this demand by producing and marketing dustproof and waterproof devices.
