Top Notch Features of Salt Spray Test Chamber which makes it a best choice for Industries

A top-notch lab testing device from Effective Lab India helps producers across several industries evaluate a material’s resistance to corrosion in real-world conditions. The name of the device is the salt spray test chamber or salt spray chamber.

Manufacturers from various industries employ various materials to build everyday instruments, electrical gadgets, and other equipment. That is imperative these materials undergo testing prior, to being used in the device’s production to ensure that the finished product meets the highest possible standards of quality.

Materials used in construction are widely used, including metals and plastics. Manufacturers evaluate the quality of these materials using various testing techniques to maintain the quality. Assessing the rustproofing for the material being used in the building is one such factor that determines quality.

What is a Salt Spray Test Machine?

A significant device in corrosion testing is the Salt Spray Test Machine, which helps assess a material’s resistance to corrosive conditions. These devices are indispensable in industries where material lifespan and durability are critical, such as automotive, aerospace, and construction. The varieties of salt spray chambers, how they function by ASTM B117 and ASTM G85 standards, and Effective Lab state-of-the-art products in this area are all covered in detail in this article.

The four main components of the salt spray corrosion test chamber’s design are as follows:

1. The electrical chamber

2. Tank reservoir

3. Tank for air pressure

4. Interior space

Salt Spray Inner Chamber

The salt spray test is carried out inside the instrument’s inner chamber. The manufacturer can test both large and small specimens simultaneously thanks to the inner chamber’s various sample placement possibilities. Because the inner chamber is securely fastened and prevents any air from escaping from the inside to the outside, it is incredibly insulated.

Tank Reservoir

The lab testing apparatus has a reservoir tank that holds a demineralized water solution and sodium chloride/salt, or NaCl. The reservoir tank is attached to an inlet pipe, which makes it possible for the reservoir tank to easily deliver the solution to the inner chamber, aiding in the humidification of the air from the air pressure tank.

Air Pressure Tank

Using the inflow pipe, the air pressure tank of the salt spray corrosion test chamber creates humidified air, which is then supplied to the inner chamber. Using an atomizer and an igus, the air pressure within the inner chamber may be supplied thanks to the air purge linked to the inlet pipe. The atomizer and igus, which are crucial pieces of equipment located at the bottom of the inner chamber, spray the solution from the reservoir tank mixed with the humified air from the air pressure tank into the inner chamber, creating an atmosphere that is resistant to corrosion around the specimen.

A fog dispenser on top of the igus helps to preserve the homogeneity of the salt spray test by allowing the concentrated fog to flow evenly throughout the inner chamber.

Electrical Chamber

The motherboard of the salt spray test chamber is located in the electrical chamber. The lab testing instrument’s manual adjustments and operation are handled by the electrical chamber. This chamber makes the control panel work, which makes it easier for the operator to do the salt spray test by encouraging one-handed operations.

Features of Salt Spray Test Chamber

High-end and cutting-edge features are packed into the instrument to increase the user’s competitive advantage.

Following are some of the Salt Spray Test Chamber’s features.

•One of the best aspects of the apparatus is the way the salt spray test chamber is built. The instrument’s inner chamber is built with a three-layer insulation made of mild steel, glass wool, and a specially made FRP material. There is no chance at all that the concentrated fog from the inner chamber will leak thanks to these three materials.

Additionally, the instrument has carefully designed air purge equipment that, before opening the canopy, reduces the amount of salt spray inside the inner chamber due to its high compressive ability to prevent corrosion or rusting of nearby electronics.

•Various sizes of the device are available to suit the operator’s requirements. Testing of even large specimens is made possible by the direct proportionality between the sizes of the reservoir tank and inner chamber. The following are the available sizes for the instrument:

1. A 250-litre inner chamber

2. A 450-litre inner chamber

3. A 1000-litre inner chamber

Safety Features of Salt Spray Chamber

To protect the operator and strengthen security protocols during test execution, the instrument is additionally equipped with several safety features.

There are astounding alarm systems available in the salt spray corrosion test chamber, covering all four of the separated components of the lab testing instruments:

1. Temperature overshoot alarm in the inner chamber

2. Overshoot warning for air saturator temperature

3. Low alert for solution level

4. The low air pressure alert

5. Low water level alert

7. An alert for overvoltage or undervoltage

Salt Spray Chamber Test Standard IS 9844-1981 PDF Download Now

This Salt Spray Chamber is made for corrosion tests on coating products and that Standard, is adopted by the Indian standards institution for conducting salt spray tests. In this test standard, there is a direct relation between salt spray resistance and corrosion resistance present in other mediums. This is because the corrosion progress is affected by several factors such as; protective film formation. Due to this, results obtained from the test can not be counted directly. Moreover, Anodized Aluminium which has a coating thickness below then 3 micrometers is not recommended for this test.
In addition, if the final value observed in the reporting of test results is rounded off, then it shall be done following IS: 2-1960.

Scope

In this test standard, the reagent apparatus and procedure of conducting the test are specified for assessing the quality of coatings made following the product’s specifications. The type of test specimen is not specified by this test standard. The detail of the test specimen is provided in the specifications of the product.

Test solution

Dissolve sodium chloride in distilled water to produce a concentration of 50+ -5 g/l. Sodium chloride should be white and give a colourless solution in the water. Also, it should be free from nickel and copper and contain a 0.1% concentration of sodium iodide. Also, take care of the pH. If the pH is more than 7.0 then investigate the presence of impurities in salt and water.
* Adjusting the pH of the salt solution is important so that the pH of the sprayed solution will be between 6.5 and 7.2. Kept the pH control based on electronic measurement at 25 degrees. Moreover, any necessary correction shall be made by adding a solution of hydrochloric acid or sodium hydroxide.
Filter the solution before placing it into the reservoir of the apparatus. This filtration removes the presence of any solid matter. The solid matter might block the spraying device apparatus.

Apparatus

The apparatus of the test should be:

A spray cabinet
Means of supplying and controlling heat.
Means of spraying the salt solution
Reservoir
Atomizers are made up of inert material.
Two suitable collecting devices.
Clean the apparatus before use.

Method of exposing test specimens

Expose the test specimens into the test chamber.
The angle of exposing samples is very important. 20 degrees vertical and be within the limits of 10-20 degrees in all cases.
Arrange the specimens, so that they should not come in contact with one another.
Support for specimens should be made up of inert non-metallic materials such as plastic or glass.
