Ensure that your products stand the test of time with Presto’s Salt Spray Chamber

Presto’s salts spray chamber is an ideal environmental chamber with the latest technology, used to create the designated temperature and humidity. It has the lowest heat loss ratio due to the high quality of insulation with imported PUF.

Why is the Salts Spray Chamber important?

Metal components, automobile parts, pipes, fittings & coated panels get damaged due to corrosion. So, it is important to check their resistance to corrosion.

This can be done using a comprehensive salt spray chamber test that meets specific international standard requirements. Manufacturers can use salt spray testing to ensure that products are thoroughly tested. This test system is like a performance indicator - showing how the product would react when exposed to harsh environmental conditions.

Salt Spray Chamber

The Corrosion chamber is a highly effective equipment used to evaluate the resistance to corrosion of coatings, paints, and mechanical parts. Here, the sample is exposed to a very intensive salt-based atmosphere, for a specified period, while considerably accelerating the corrosion process.

The industry standards state that a product should be tested, under accelerated conditions for 240 to 1000 hours. However, the period can be customized according to specific requirements. Manufacturers of corrosion protection coatings can apply different kinds of coatings and weather-resistant products from their extensive range.

What Can Be Tested Using Salt Spray Chamber?

A wide variety of products can be tested using the Salt Spray Chamber, to perform corrosion testing. This includes coated & uncoated panels, screws, nuts & bolts. It can also be used for finished parts, consumer products, kitchen appliances & tools. Furthermore, manufacturers can also test automobile components, mechanical parts, springs, and bearings.

Salt Spray testing system is widely used in the Automotive, Paint, and coating industries.

This simple test is used to check, the corrosion resistance of parts or finished surfaces. When it comes to OEM manufacturers or suppliers - all components need to be thoroughly tested and documented for their corrosion resistance.

Why Conduct Corrosion Testing?

1. Durability and Protection –

Manufacturers can estimate the service life of the component/product by performing a standardized accelerated corrosion test of the product. The cyclic corrosion test can be conducted to ensure that products are adequately protected throughout their life span. During the test cycle, they can monitor the corrosion levels at specified time intervals by also opening the cabinet and taking photographic evidence of any surface oxidization.

2. Performance Indication Results-

The Salt Spray Test is a reliable source for predicting the suitability of a protective coating. One can compare various samples, to provide effective corrosion resistance. Precise environmental test conditions are created by the tester. Throughout the test cycle, the technicians examine the metal plate surface for evidence of corrosive characteristics.

3. Blistering and Creep Defects –

Blistering and creep defects are analyzed by the technicians. Technicians are specially trained to search and assess edge protection, especially, when checking the surfaces.

There’s provision for numerous small metal panels or objects to be accommodated in the chamber. This allows the QC department to compare multiple products, scientifically in the same controlled test environment. The process when corrosion is evident underneath the coating is called “Creep”. Here, a membrane is formed, which exposes the untreated surface to air and moisture. Soon, in the center of the metal test panels, blistering can be observed.

How Can the Corrosion Tester Be Standardized?

In salt spray testing, refined salt is used, with a purity that meets the latest requirements. International Standards to comply with, for Salt Spray Test Chamber are - ASTM B117 and JIS Z 2371 standards. A sophisticated atomizer is fitted into the equipment. It ensures an even distribution of salt spray and precise collection rates throughout the chamber.

FAQs related to the salt spray chamber

Q1. What parameters are controlled during a salt spray test?

A1. The following parameters can be controlled :

• Temperature is typically maintained around 35°C (95°F).

• Salinity usually remains 5% NaCl solution.

• The pH level Should be between 6.5 and 7.2.

• The spray rate must conform to specific standards.

Q2. How long does a typical salt spray test last?

A1. The duration varies based on the material and the specific test requirements. Various standards such as ASTM B117 ETC determine the duration for various materials. Presto’s cyclic corrosion tester  can conduct the test from 24 hours.
